AMD CEO: The Next Challenge Is Energy Efficiency
- deleted 4y ago[deleted]
- Kon-Peki 4y agoEnergy efficiency and improved packaging are things I can readily agree with. The last thing though - “hybrid algorithms leveraging AI efficiency” sounds an awful lot like a buzzword sales pitch. This article reminds of this other one [1] posted about 1 month ago. It’s an interview with some guys that just got done building an exascale supercomputer, in which it was originally estimated to need 1000 megawatts but ultimately only needs 60. The reporter asks about zettascale and the power requirements; they wave it off and say that the big question about whether it will even be possible in the next 10 years is getting the chip lithography small enough so that you can physically build a working zettascale supercomputer.

- unixhero 4y agoWhat are hybrid algorithms supposed to be anyways? Half algorithm & half dictionary? Half algorithm & half user manual? Half algorithm & half class?
- LilBytes 4y agoHalf SQL statements and half array.sort() methods I assume.
- abudabi123 4y ago(solve (this :by strong-ai) (that :by weak-ai))
- shmerl 4y agoFrom the article it looks like half AI guessing the solution, half some static algorithm fixing the result to be better. Not sure how it's supposed to really work.
- adgjlsfhk1 4y agoone variant of this is sciml approaches where you use an ODE solver wrapped around a NN. the ODE solver guarantees you get the right conversation laws which NNs don't do well and the NN is more accurate than the hand written model since it doesn't ignore the higher order effects.
- CuriousCosmic 4y agoGenerally the concept of hybrid algorithms is: - Half "hard maths" algorithms. i.e. cominbatorics, geometry, etc. - Half "fuzzy maths" algorithms. i.e. heuristics, approximation, machine learning. The idea being to solve the parts that can be easily solved by hard maths with those hard maths so that you can reduce the problem space for when you apply the fuzzy maths to solve the rest of the problem. In other words, it's taking the problem, breaking out discrete pieces to solve with well established hard maths, using heuristics & numerical solutions to tackle the remaining known problems without "easy" analytical solutions, then using ML to fill in all the gaps and glue the whole thing together.
- ororroro 4y agoThe article gives a concrete example in the same paragraph: "For example, AI algorithms could get close to a solution quickly and efficiently, and then the gap between the AI answer and the true solution can be filled by high-precision computing." Interestingly the example is backwards (statistical reasoning first, hard reasoning second) compared to traditional usage of "hybrid" in AI and control contexts.
- Dylan16807 4y agoThat's not concrete at all.
- Certhas 4y agoHalf conventional HPC simulation that runs best on CPU, half Neural Networks that need GPUs. As proposed for example here https://www.nature.com/articles/s41586-019-0912-1 https://www.nature.com/articles/s41586-019-0912-1 and here https://www.nature.com/articles/s42256-021-00374-3 https://www.nature.com/articles/s42256-021-00374-3 > The next step will be a hybrid modelling approach, coupling physical process models with the versatility of data-driven machine learning. The Frontier HPC system that AMD just delivered is aimed fully at that problem. https://en.wikipedia.org/wiki/Frontier_(supercomputer) https://en.wikipedia.org/wiki/Frontier_(supercomputer)

- jayd16 4y agoI assume it means using ML to choose between multiple algorithms instead of more traditional heuristics. That or the algorithms use a combination battery and gasoline.
- evancox100 4y agoRe. The “hybrid algorithms” bit: I was at this talk. The example she gave was a physics sim like CFD, iterating between a fast/approximate ML-based algorithm and slow/accurate classical physics algorithm, with the output of each feeding in as the starting point of the next round. But this was just an example, clearly there are lots of area you could apply a similar approach.
- greenknight 4y agoI think its also leaning into their new product MI300, which has 24 cpu cores with 8 compute dies. Both CPU and GPU (and memory) on a single package. Conventional processing + AI together. Hybrid approaches.
- evancox100 4y agoYes they were really crowing about MI250X adoption and touting the upcoming MI300
- m_mueller 4y agoAfaik, having worked in HPC, one area where this can be employed is error bias correction of CFD models. E.g. weather models have various biases that need to be corrected for - so far this is just done with some relatively simple statistics afaik.
- PartiallyTyped 4y agoSo differentiable programming with nns as approximators? Cool!
- Certhas 4y agoThe main thing AMD has in their accelerators that enables this this is unified memory between CPU and GPU. Thats really interesting.
- tankenmate 4y agoDon't forget that AMD also bought Xilinx
- WithinReason 4y ago“hybrid algorithms leveraging AI efficiency”: An example I came across recently: https://arxiv.org/abs/2202.11214 https://arxiv.org/abs/2202.11214 A neural network-based solution for weather forecasting: "FourCastNet is about 45,000 times faster than traditional NWP models on a node-hour basis."
- JustSomeNobody 4y ago> The last thing though - “hybrid algorithms leveraging AI efficiency” sounds an awful lot like a buzzword sales pitch. It's supposed to. Investors want to hear this, not some crap about efficiency, when the entire world is talking about AI. Edit: TBC, I care about efficiency and it's not crap, but that's likely the view of investors.
- pessimizer 4y ago> The last thing though - “hybrid algorithms leveraging AI efficiency” sounds an awful lot like a buzzword sales pitch. Oddly, to me this just sounds like efficiency gains by potentially introducing massive security holes i.e. the vector of the Meltdown/Spectres of the future. It also seems like they're trying to sell AI as some sort of secular qubit that they'll be error-correcting.
- agumonkey 4y agoNot a cpu designer, but I remember AMD using AI for branch prediction since long ago. Hopefully they still mention AI in that sense and not only branding.
- undersuit 4y agoAMD already uses a Perceptron for their branch prediction. I would say they're talking about support for ML speed ups in hardware but maybe the plans also include a more complex complete neural net in hardware for data prediction.
- vlovich123 4y agoWhen I was an undergrad, one of my professors was exploring “approximate” computation (forget what it was technically called). The gist was that you build mathematical circuitry that approximates an answer instead of giving you a concrete answer (kinda like floating point but also applied to Boolean algebra, integer math etc). The reasoning was that the approximation could let you reduce the power. I wonder where that line of research has gone.
- cplusplusfellow 4y agoWhat if all the text in your comment was approximately the correct set of letters in each word?

- anonymouskimmer 4y agoThis line was worth reading! > dig the life that both are scary and jamming lore whose biased top must be recoverable.
- myself248 4y ago"Fuzzy logic" was the "AI" hype buzzword of the 90s.
- georgeburdell 4y agoSu is just talking up AMD’s strengths, many of which come care of TSMC and for which the original R&D was largely funded by Apple. She is not wrong, and AMD has certainly made large gains in HPC recently, but AMD does not monopolize all possible paths to success here.
- greenknight 4y agoI agree that a lot of AMDs wins have come from TSMC. That being said, I feel like the biggest win for them over the past 5 years (well 6 now)... was moving to chiplets, which all started at Global Foundaries. Having the same chip, from the lowest end consumer chip all the way to the top end server chip means that they can spend less time and cost developing up processors for every segment, and they just bin the chips in terms of quality. Intel is starting to make changes towards this structure but they haven't fully committed to it yet.
- bitL 4y agoA move to chiplets would be just prolonging their terminal suffering if they didn't replicate Haswell in the first Ryzen chips, making them somewhat performance-competitive and due to chiplets also economically viable with the ability to wow consumers with the first 8 core desktop chips and later 12/16/24/32-core ones.
- spixy 4y ago5nm? It was also funded by AMD since it is their customer, and by many other customers.
- georgeburdell 4y agoAMD just released a 5nm product a few months ago. Apple’s M1 is a year older. Apple funded 5nm
- unixhero 4y agoWe have know this for a long time. This is one of the benefits of ARM64 CPUs as they require much less energy. What's new about his point?
- deleted 4y ago[deleted]
- howinteresting 4y agoThey definitely don't require "much" less energy. Zen 4 is very close to the M series in perf per watt
- unixhero 4y agoYes ARM isa requires less power. Why do you think we don't have mobile chips with Intel x86 instructions...
- cletus 4y agoPut another way: if AMD (and especially Intel) don't do something about this they're going to get completely eaten alive by ARM. The amount of processing power available in a modern smartphone is truly mind-boggling. I'd love to see a chart showing the chip cost and energy cost of the power on an M1 chip in each previou syear. I would guess that 30+ years ago you'd be in the millions of dollars and watts of power but that's just a guess. As we see from the modern M1/M2 Macbooks, these lower TDP SoCs are more than capable of running a computer for most people for most things. The need for an Intel or AMD CPU is shrinking. It's still there and very real but the waters are rising.
- beebmam 4y agoIn my own experience, the supposed ARM chip superiority claims are almost entirely marketing. I get significantly better performance (15-50%) from nearly all of my CPU workloads on modern Intel/AMD hardware vs the ARM Apple devices.
- CalChris 4y agoThe article is about energy efficiency. Do you get 15-50% better performance per watt from nearly all of your workloads?
- Salgat 4y agoIf you take a Zen 3 running at optimal clocks for efficiency (such as the 5800U) the difference between its computing performance per watt is competitive with the M1 if you account for the difference in node size (which TSMC claims gives 30% less power consumption at the same performance). As the article points out, the real efficiency gains will be domain specific changes such as shifting to 8 bit for more calculations.
- jorvi 4y agoHow would x86-64 be as efficient with the same transistor & power budget when they have to run an extra decoder and ring within that budget? Seems physically impossible.
- mattmaroon 4y agoThe next challenge? You mean the one that started 15 years ago?
- fastball 4y agoRight? Like, isn't that one of the reasons people have been raving about Apple's MX chips? Because they're very energy efficient and have good performance characteristics?
- rektide 4y agoAMD has done extremely well with multi-chip(let) modules. Zen cores & zen clusters (on Core Chiplet Die, CCD) are wonderfully small, and a huge amount of the regular stuff cores do is relegated to the IO Die (CCX), which is not as cutting edge. But wow there's a bunch of power burned on interconnect between CCDs and CCX. And now AMD's new southbridge, Promontory 21, made by Asmedia, is another pretty significant power hog, and the flagship X670 tier is powered by two of these. There's absolutely a challenge to bring power down. I'm incredibly super impressed by AMD's showing, & they've done very well. But they've been making trade-offs that have pretty large net impacts, especially if we measure at idle power.
- deleted 4y ago[deleted]
- aidenn0 4y agoI'm not up-to-speed on modern chipsets, but WTF is the Southbridge doing that it needs that much power? Is Thunderbolt going through it or something? I think of the Southbridge as a mostly ignorable part of the chipset (up until something goes horribly wrong).
- bayindirh 4y agoSingle word: PCIe. Lots of fast PCIe lanes eat a lot of energy. A server motherboard contains tons of more PCI devices when compared to a consumer desktop systems, and they are not the cards, but the small units enabling the advanced features in servers, which are embedded on the motherboards themselves. Thunderbolt is just a PCIe encapsulator of some sort, which can also do plethora of other things.
- temptemptemp111 4y ago[dead]
- andrewstuart 4y agoAMD is having some challenges at the moment. In particular, the RDNA3 graphics card line launch has been a dud. The Nvidia 4090 turned out to be far ahead of the AMD 7900XTX. Then there turned out to be an overheating issue on the AMD cards. And now it just looks like both Nvidia and AMD are price gouging GPU buyers instead of competing with each other. They are deliberately keeping prices high and creating artificial shortages of GPUs, because that's what kept prices high during covid/crypto mining. I used to be really cheering for AMD as the underdog, but I guess its true that none of these companies are your friend, they're just there to shake you down. AMD had a chance to really pull ahead of Nvidia by being "the good guy" and actually offering end users great value for money, but instead they've chosen to emulate Nvidia. Substantial customer good will has been lost by AMD.
- fsckboy 4y ago>They are deliberately keeping prices high and creating artificial shortages of GPUs you've seen evidence for this, or it's your opinion? >AMD had a chance to really pull ahead of Nvidia with a graphics card line that you just told us is far behind Nvidia's?
- ommz 4y ago>you've seen evidence for this, or it's your opinion? Probably alluding to the under-shipping of GPUs; stated by Lisa Su during the recent investor call[0] [0]https://www.fool.com/earnings/call-transcripts/2023/02/01/advanced-micro-devices-amd-q4-2022-earnings-call-t/ https://www.fool.com/earnings/call-transcripts/2023/02/01/ad...
- lmm 4y ago> with a graphics card line that you just told us is far behind Nvidia's? Cheap and good enough can absolutely be a way to win.
- andrewstuart 4y agoYup. If AMD actually competed on price then they'd be shifting the GPU market away from Nvidia. They seem content however just be second best but making bank.
- polski-g 4y agoWhat don't they just make the chips bigger so there is more surface area contact on the heat sink?
- mort96 4y agoThat might work in the narrow case of desktop. In mobile (anything with a battery really), it obviously doesn't work because you care about battery life. In server, it doesn't work, since two of the main costs and limiting factors in data centers are power and cooling.
- AtlasBarfed 4y agoSo.... that means an Apple M1 killer is in the works? Anybody? That's the type of energy efficiency everyone can get onboard with. Also, IMO software needs to take a lot of responsibility for energy efficiency, we just pawn that off on the hardware vendors. I wonder what the carbon cost of javascript is, I don't think I'd want to see the results, or python for that matter.
- foreverobama 4y ago[dead]
- Loic 4y agoWe can see in practice the gains in energy efficiency coming from very close integration from short distance, to chiplet, to everything on one die. These are our mobile phones down to the Apple M1/M2 laptops with a motherboard having everything packaged into the size close to the size of a mobile phone board.
- KingOfCoders 4y agoIt's amazing on how you can power limit the newest Ryzen to only 105 and get high energy safes for much less performance reductions. But the review-game (same reviewers who complain about power usage) drives AMD/Intel to get the last 5% of performance increase for 20% of power increase.

- apatheticonion 4y agoFrom the perspective of a consumer, my MacBook Pro is basically the perfect laptop, at least in theory. I love the battery life and performance of the hardware, not to mention the unrivaled build quality of the MacBook (screen, trackpad, keyboard). In practice, however, MacOS limits the capabilities of the hardware such that I cannot daily drive my MacBook Pro as a work or personal computer (poor containerization support, an annoying development toolchain, and no _real_ support for video games). When Asahi Linux is mainlined, stable and features full hardware acceleration - the MacBook running Linux will likely be the best laptop money could buy. Until then, please AMD, Intel, release some mobile hardware that's at least as good. It sucks so bad seeing what is possible with today's technology but that being exclusive to a company unsuccessfully determined to ring fence you into their API ecosystem.
- kanbara 4y agoi've used a mac for development for various projects which have been globally impactful for over a decade. it's literally unix, man. docker on mac can be improved, but if i'm developing for other architectures it's much easier to just test natively. toolchain for all the languages i use is exactly the same as any other *nix. gaming i'll give you a point, but that's why i have windows dual boot at home. /shrug
- unxdfa 4y agoIt’s Unix but it’s not Linux. When Linux is your target it makes sense to use it on your development stack entirely. The irony being that Microsoft seem to make the best Linux OS for development for my use cases of docker / server side / cloud operations. And it runs Office better than Linux or Mac.
- jb1991 4y ago> The irony being that Microsoft seem to make the best Linux OS for development WSL?

- kramerger 4y agoPeople criticising the AI talk, remember that they achieved great CPU performance improvement by adding AI to the look aside buffers. Looking forward to even more efficient Zens, my next laptop will definitely be an AMD
- dr_zoidberg 4y agoI've been using a Zen2 notebook for the past few years, and was honestly surprised by the processors performance for the first... 3 or 4 months. Then typical updates happened. And some quirks got in the way too. Like it having a decent iGPU that I can't use because the BIOS will only let me pick one of them (down to it not having a mux to pick one or the other? Not sure what's going on there, just that I can't do it). In general it's a great machine, but there's a host of little details that make the experience a bit worse than it should be. Per my usual update schedule, I'm looking down the line to at least a Zen5(+?) upgrade in a few years time, so I hope they improve this kind of things in the future. However that's entirely up to OEMs deciding to make a good product, and a bit out of AMDs grasp.
- hkt 4y agoHas the environmental impact of less efficient processing been studied? I've been thinking about this since seeing those stories a while back about bitcoin miners collectively having the same power consumption as some smaller countries. If anyone knows a dataset suggesting what % of world energy usage is used by computing hardware (and what proportion of that hardware is idle vs fully utilised) I'd love to see it. Also, less on topic, what's the environmental impact of writing your app in something programmer friendly but power inefficient? I strongly suspect some big tech companies will be suffering with this (namely anyone who is still on RoR at scale).
- LatteLazy 4y agoWhen I worked on London Underground, we investigated regenerative breaking and found it wasn't worth it for the power savings BUT it was worth it to reduce temperatures on platforms (LU applied a £ value to the comfort of passengers for modelling purposes). Interesting to see the same fundamental issue at the nano scale...
- sylware 4y agoAnd RISC-V ISA.
- neverrroot 4y agoIf Intel could also think about same. My Thinkpad X1 Nano Gen 2 with Alder Lake has only 50% battery runtime of what X1 Nano with 1160G7 accomplished. For pretty much the same performance. Power constrained to say 5 or 7W, the 1160G7 feels faster. I hope that Lenovo can offer something so light as a X1 Nano with AMD inside. Technically it should be both possible and feasible, given that the AMD CPUs are much more efficient/performant at low power levels.
- irusensei 4y agoLooking forward to this. It seems lately you can only get < 35W x86 CPUs through laptops or some very niche vendors or even mystery sellers on alliexpress. I’d like something that idles at sub 5W like ARM SBCs do but without the whole OS or boot jank. I’m pretty sure people will suggest x86 options that fit into that description but again it looks like you have to scrape the internet for stuff like intel 1[2,3][1-9]00t or wathever the AMD alternative is.
- naoru 4y agoAnecdotally, I use a CPU from an aliexpress mystery seller in my desktop machine. It's a i9-9980HK with about 40W TDP... Which I unlocked to ~300W and installed a water cooling system. It can idle at around 5W, but a synthetic load (e. g. prime95) quickly makes it draw full 300W and then throttle a bit. Fun stuff, definitely wouldn't do it again due to enormous strain on the PSU and an unreasonably high power draw relative to performance.
- AshamedCaptain 4y agoThere are many many machines out there with x86 soldered CPUs all of them idling at less < 10W. E.g. ASUS PN-series with Celeron CPUs. You can even find them on physical stores. I have a PN40 idles at less than my RPI4b...
- jillesvangurp 4y agoTypical for a company that is stuck to be calling out what they should have been doing for the last decade as the thing to focus on. Basically he's promising more of the same. What he should be doing is announce the next big thing. Which I imagine might include trendy things like tackling AI with some hardware/software stack that is energy and cost efficient and competitive with nvidia. Or a non intel architecture based chip intended for high end gaming/ar/vr type devices where energy efficiency and performance are going to matter more than compatibility with legacy PC hardware. AR is going to suck if you have to be tethered to a huge power supply or battery and carry a liquid cooling apparatus with you. This requires a different approach. And even those things really should have been the focus for the last ten years. A slightly faster version of the thing they've been selling for the last ten years is not going to turn things around and there are only so many people still assembling PCs from parts that actually know and appreciate AMD as a brand.
- speedgoose 4y agoI think it’s a she.
- Tuna-Fish 4y ago1. She. AMD's CEO is Lisa Su. 2. This is a keynote at a supercomputing conference. The audience are people who do supercomputing. She's not going talk about consumer stuff. 3. She did announce new, integrated products that are in at least some niches better than what nVidia has. 4. AMD brand is flying very high on the server and supercomputing side right now. They have beat Intel for 3 generations straight now. In general, you should read the article instead of commenting based on just headlines. Doing this just makes you look really stupid.
- Tepix 4y agoThey could score a quick win for power efficiency by making the Ryzen 9 5900 and Ryzen 9 3900 12-core 65W CPUs generally available instead of only selling them to OEMs.
- bayindirh 4y agoIf your production process and binning doesn't create enough supply for these parts, you only sell them to OEMs, because they can silently discontinue, or limit availability of these models when parts can not be found. However it'll be a PR disaster if the parts have spotty availability in retailers, and will cause wild rumors to spread, from "AMD doesn't want you to have this CPU" to "AMD is going bankrupt".
- Tepix 4y agoSure. But since AMD has been producing these CPUs for a while, their yield should be good by now, shouldn't it? Anyway, I hear some people saying you can just buy the 105W "X" variant and limit the power usage to 65W in the BIOS. Does it really give the same result, also in idle power consumption?
- greatpatton 4y agoIt's not a yield issue if your product is only a byproduct of another one.
- deleted 4y ago[deleted]
- pb82 4y agoI'm running my 5800x in 45w Eco mode. It does not improve idle power from what I can see. It only limits the max it can draw.
- deleted 4y ago[deleted]
- 4y ago
- sparkie 4y agoTo reduce power usage by any significant amount, need to get rid of the clock.
- moffkalast 4y agoInstructions unclear, threw alarm clock in dumpster.
- bob1029 4y agoI have never seen a realistic proposal for how this would make a practical consumer PC work better. Having a clock that every component can agree upon means that components don't have to worry about each other anymore. Physics and information theory would suggest that removal of this centralized clock signal necessarily introduces additional latency in order to safely determine or modify system state.
- PedroBatista 4y agoThe last time a chip company talked about "Efficiency" in this way, we got +10 years of 5% increments in performance and 50% in price increases for 2 and 4 core CPUs.. I know it's my PTSD, the words make sense but I really hope this is not code for "we can't get much more performance out of our architectures, so we'll focus in selling "efficiency".. " I really hope I'm wrong, since the power consumed by this chips has gotten a bit out of hand ( not as much as the GPUs.. )
- eric__cartman 4y agoARM CPU manufacturers have been doing that for more than a decade :)
- PedroBatista 4y agoYes, but real world performance ( aka compute speed ) has been like desktop Linux, "it's here, but not really" ( we are talking about general desktop, laptop, server here, not mobile ). Having said that, Apple's M1 was the real one that changed things, also ARM on the server is starting to actually be a mainstream thing, so I get why AMD and Intel are sweating, I just hope they can pull it off because a World where you need to buy a +$1000 aluminum box attached to the CPU you want to get is not a better World.. or worse: Doing business with Qualcomm.
- weberer 4y agoDesktop Linux has been better than Windows out of the box for more than a decade now. Unless you're talking about market share, which will never increase without a hundred million dollar marketing blitz behind it.
- kubb 4y agoIf they could integrate everything into one chip, it would make for great gaming PCs. Quieter, smaller, performant, low power.
- PaulHoule 4y agoIt seems the more power saving features I turn on, the more my computer crashes. No thanks!
- amatheus 4y agoWell, given the chips Apple have released and all the work it has done on efficiency I think this is the current challenge, not the next.
- oolveea 4y agoWill neuromorphic chips ever go main stream amongst AI practitioners? The neurons on these chips are spiking, which is a whole different paradigm what is currently used in neural networks? These chips are however a thousandfold more efficient.
- madmax96 4y agoThis is not a completely hashed-out thought. But I'll share it and see what others think. My impression is that the simplest way to improve energy efficiency is to simplify hardware. Silicon is spent isolating software, etc. Time is spent copying data from kernel space to user space. Shift the burden of correctness to compilers, and use proof-carrying code to convince OSes a binary is safe. Let hardware continue managing what it's good at (e.g., out-of-order execution.) But I want a single address space with absolutely no virtualization. Some may ask "isn't this dangerous? what if there are bugs in the verification process?" But isn't this the same as a bug in the hardware you're relying on for safety? Why is the hardware easier to get right? Isn't it cheaper to patch a software bug than a hardware bug?
- plq 4y agoThis sounds like an exokernel design. What forces you to use the compiler that generates the trusted code to replace the MMU?
- verdagon 4y agoPerhaps instead of distributing program executables, we can distribute program intermediate representations and then lazily invoke the OS's trusted compiler to do the final translation to binary. Someone suggested a Vale-based OS along these lines, it was an interesting notion.
- fireant 4y agoWASM could be such an IR unironically https://github.com/nebulet/nebulet https://github.com/nebulet/nebulet. But I doubt that we would be gaining performance/efficiency this way.
- stonemetal12 4y agoI doubt it. Special purpose hardware is usually more efficient than a software implementation running on general purpose hardware.
- psychomugs 4y ago“I will take tech futures for $800.” “What is AMD’s next challenge?” “Efficiency.” “Sorry, the answer we were looking for was ‘less.’”
- esskay 4y agoI dont think Intel or Nvidia got the memo on this. Both are pumping out seemingly more and more desparate products where their solution to more performance is just to throw more power at it, causing obscene levels of heat in the process. Meanwhile down at the mid-end you've got Apple chipping away at them with ultra efficient ARM chips.
- foolfoolz 4y agowhat? the 4x series cards are the most energy efficient graphics cards ever made. ignore the 4900, they just scaled the top end to have high power and high performance. look at the low tier. they all have significant power requirement reductions compared to the 3x cards. watts per fps is down
- ribit 4y agoHappy to hear that AMD takes these issues seriously. The power draw of current Intel and Nvidia chips is seriously getting out of hand. There is absolutely no justification for drawing 40-50 watts of power for rendering a website!
- mkoubaa 4y agoJust in time for micro nuclear reactors to be commercial I suppose
- imwillofficial 4y agoWay to skate to where the puck was AMD.
- zepmck 4y agoThe next challenge is software stack.
- awill 4y agoAMD should build an arm chip. There's only so much efficiency you can build into the ageing x86_64 architecture
- bob1029 4y agoThe only reason ARM is competitive with x86 is due to heavy borrowing of its tricks (i.e. OOO execution). At the end of the day, Apple M2 and AMD Ryzen cores are not all that dissimilar.
- tas2642 4y agoAMD CEO, Dr. Lisa Su, has identified energy efficiency as the next challenge for the company. With the growing demand for high-performance computing, it is crucial to ensure that energy consumption is minimized to reduce the environmental impact and operating costs. AMD has already made significant progress in this area with their latest processors that deliver excellent performance while consuming less power. Dr. Su's focus on energy efficiency underscores AMD's commitment to sustainability and innovation, and we can expect to see further developments in this area in the coming years.
