Intel Core I7-11700K Review: Blasting Off with Rocket Lake
- giuliomagnifico 6y ago291W... whoa!
- meepmorp 6y agoYeah, that’s getting into space heater range. Edit: Temperature peaks on some workloads up to 100c. Jeez
- Cullinet 6y agowe simply need a radiator or exchanger design to plug in to our domestic water supply at least I'll be very happy with either free compute or free hot water pov depending.
- hnuser123456 6y agoGood thing nobody actually uses AVX512
- rbanffy 6y agoInterestingly enough, the AVX512 test was the easy win for Intel. Nobody uses it because it wasn't available and, when available, wasn't much faster overall. Now it is.
- Cullinet 6y agoiirc wasn't until recently available in the HEDT line, but the user base is equipped with scalable xeon boxes not awfully constrained desktop chips.
- rbanffy 6y agoI'm imagining its availability will have more impact outside the user base that's already well served by Xeon Scalable. Visicalc didn't make a big impact in mainframes.
- kcb 6y agoIs it though? The vast majority of PCs even on the enthusiast level aren't going to have coolers that can handle 300w for any sustained period.
- rbanffy 6y agoFrom eyeballing the chart, they'd only need to handle the load for 20% of the time compared to non AVX512 CPUs to be equivalent. Anything more is an advantage.
- kllrnohj 6y agoWho both buys consumer desktop CPUs (without ECC) and runs software that can use AVX512? Games won't use avx512 (not really simd math heavy work on the CPU, and also consoles don't have it). Web browsers won't use AVX512 (similar to games - not really SIMD-friendly raw math computation limited). Video & photo editing maybe will, but GPU acceleration is already more widely available & faster than avx512. What else does that leave?
- krapht 6y ago<-- this engineer's company workstation uses a consumer desktop CPU Most scientific and engineering computing applications use double precision floats.
- rbanffy 6y agoHow many of those workloads would benefit from it if it were more available? I'm not sure, but we haven't seen it being widely deployed just yet.
- 37ef_ced3 6y agoAVX-512 software is appearing. For example, for neural net inference: https://NN-512.com https://NN-512.com AVX-512 is a pleasure from the programmer's perspective, much nicer than writing software for GPUs or for earlier SIMD instruction sets like AVX2/SSE Versus a GPU, the AVX-512 machine model is just much simpler, and there are no drivers or proprietary compilers Versus earlier SIMD instruction sets, AVX-512 provides all the instructions you want (permutations, floating point conversions, etc.) and they're all masked so edge cases are easy. AVX-512 Foundation is a really nice instruction set and it has a bright future
- dogma1138 6y agoIsn’t the issue with AVX-512 is that different CPUs support different instructions? https://en.m.wikipedia.org/wiki/AVX-512 https://en.m.wikipedia.org/wiki/AVX-512 It might eventually get normalized but atm it’s a bit of a mess.
- wtallis 6y agoIt's a bit less messy if you ignore the GPU-like Xeon Phi (Knights Landing and Knights Mill) and the failed Cannonlake that Intel definitely would prefer everyone pretend never happened. But that still leaves you with a progression of four levels of expanding support, and the Cooper Lake mess of having BFLOAT16 but not the stuff added in Ice Lake and Tiger Lake. If you don't cut down the support table to eliminate irrelevant niche products, it's most of the way to being a Gray code.
- dogma1138 6y agoI think Icelake and Tiger lake not having BF16 is going to be a big issue especially for machine learning applications, I can’t find what Rocket Lake supports yet but I’m guessing it’s going to be similar to Tiger Lake. There is also the big unknown of what kind of support AMD will bring to the table. I think Intel is banking on people using OneAPI more than writing AVX-512 code using intrinsics or compiler magic. At that point compatibility might be not as much of an issue if you ignore potentially drastic differences in performance.
- Cullinet 6y ago37ef_ has covered why AVX512 is plenty in use internally everywhere I know. Shrink wrapped products, not so much.
- deleted 6y ago[deleted]
- CapriciousCptl 6y agoAnd 104*C without overclocking! Sounds like they’re pushing the envelope.
- mirekrusin 6y agoThey should drop in kettle stand as a free gift.
- fctorial 6y agoctrl-f 104 didn't bring up anything
- AmVess 6y agoIntel has really lost it. My Ryzen 8 core CPU is easy to cool with a quiet set of fans. Cooling this for real work will require a custom watercooling set up...and it isn't even as fast as a Ryzen 8 core CPU.
- outworlder 6y ago> 291W... whoa! Truly a rocket. All it needs is a nozzle and some reaction mass. Maybe they should pivot? "Intel exhaust outside". Do some computations and get thrust for free!
- floatboth 6y agoTo be fair that's the peak under AVX-512, and looks like early firmware that might not do all the power management right yet. Still, I can't get my 5950X to ever come anywhere close to that, even running AVX2 Prime95 with max overclocking tops out at 190-ish IIRC.
- celrod 6y ago4.6 GHz all core with AVX512 surprised me. At least AVX512 downclocking seems to be a Skylake problem. Ice Lake (which Rocket Lake is a backport of) similarly doesn't downclock much: https://travisdowns.github.io/blog/2020/08/19/icl-avx512-freq.html https://travisdowns.github.io/blog/2020/08/19/icl-avx512-fre... The 100+C temperatures suggest it probably should downclock a bit, at least on 14nm.
- guardiangod 6y agoi7-10700K to the i7-11700K Single thread floating point: +19.0% Multi-thread floating point: +19.5% Single thread integer: +13.0% Multi-thread integer: +7.3% Jesus. Just overclocking the RAM for the 10700k would give a similar performance increase. Along with 291W, this 10nm->14nm backport is not working out well for Intel. PS My work desktop died on Wednesday afternoon during the SpaceX SN10 flight. I rushed to my local computer store to replace it. Out of the entire store, only 2 motherboards models with Intel's LGA1200 are in stock. All the other motherboards on the shelf were for AMD. I picked the i5 10400f as it's under deep discount. I asked around and everyone agrees that Intel is competing only on price point right now.
- nullifidian 6y agoIs it a backport? I read somewhere that it's a continuation of Skylake evolution and not a new architecture.
- imajoo 6y agoAccording to the article, "The new generation Rocket Lake is the combination of two different backported technologies. Intel took the Sunny Cove core from 10nm Ice Lake, and re-built it on 14nm, calling it now Cypress Cove. Intel also took the Xe graphics from 10nm Tiger Lake and re-built those on 14nm, but these are still called Xe graphics." So, yes, it appears to be a backport.
- deleted 6y ago[deleted]
- guardiangod 6y agoRocket Lake was designed for 10nm, but Intel couldn't get 10nm to work, so they backport Rocket Lake to 14nm. https://semiaccurate.com/2020/10/29/intels-palpable-desperation-on-display-with-rocket-lake/ https://semiaccurate.com/2020/10/29/intels-palpable-desperat... Just filter out Charlie Demerjian's grudge against Intel. Companies don’t backport because a core is designed for a process. It’s efficiency and architecture is based on the transistors that it will use from the design start, caches are sized based on the process too, and a lot of the architectural gains are due to the added transistor counts. If you backport a CPU you lose the efficiency of these new transistors so the energy use goes up and the clocks likely go down as well. Cores take up 2x the size, or at least a lot more than the older core did on the older process, so costs go up too. You can either cut out bits of the core and lose performance or eat it on area and therefor cost. Backporting a design not made for portability isn’t a lose/lose proposition, it is a lose/lose/lose/lose proposition. But Intel is desperate so…
- jpgvm 6y agoRIP Intel... They need their new process node and whatever new architecture they have in the pipe to land -soon-. Looks like my 9900k might be the last Intel processor I buy for a long time unless things drastically change.
- oumua_don17 6y ago>> land soon Not soon but yesterday
- redisman 6y agoThe next big desktop release will be whatever comes with the new AM5 socket so they have some time to get their act together. I don’t have high hopes that they can actually compete and now Apple also leapfrogged them with non-desktop chips
- rglullis 6y agoEither I had really bad timing or bad luck, but somehow I am ending up with Intel even though I really wanted to switch. Around 2012 I bought a 4-core Core i5 and after some basic upgrades (max RAM to 32GB and a good SSD) it had more-than-acceptable performance for my work until mid-2018. Even when I dabbled with Machine Learning I borrowed a 1070 from my office and was plenty to run my tasks. Around end of 2018 I started working more in different offices, so I needed a more powerful laptop. No strong offering from AMD yet, so I ended up with a System76 core i7, 6-core 32GB RAM. 2020 came and with it I got back into working at home. So I got excited about upgrading my workstation. I bought all the components to get a Ryzen 5, a 3700X I think. What a shitshow: had to go through three different pairs of RAM to find one that was actually compatible with the motherboard. Then I had to find a way to upgrade the BIOS, and I could only do it by getting an Athlon CPU. BIOS upgraded, then the original 3700 died. I ended up turning the whole system into a very expensive media center just with the Athlon and continued working with the laptop. A couple of weeks ago my laptop's battery puffed up, so I decided to go look again into a nice desktop. An 12-core Ryzen 5900X is coming out at 900€ and a basic motherboard is 300€. 10-core Intel i9-10900 is 300€ and a motherboard for it is 180€. Guess which one I ended up taking and that I managed to get running without any issue whatsoever? Here is to hope that in 6-8 years from now I finally manage to make the switch to AMD. (Edit: why the downvotes, HN? It's an honest account of my experience.)
- rubyist5eva 6y agoIntel is on my shitlist now for their new "Coalition for Content Provenance and Authenticity" with Microsoft and Adobe. I don't care how fast their CPUs are, they are dead to me.
- jimbob45 6y agoWould you like to explain why for those of us out of the loop?
- LegitShady 6y agohttps://contentauthenticity.org/our-members https://contentauthenticity.org/our-members Basically a large group of companies are forming a group to create an agreed upon fingerprinting system for 'content' (read: everything) to destroy privacy in the name of 'fighting disinformation'.
- smt88 6y agoIsn't such a thing necessary as we see US presidents falling for (deep)fake media? Is there a privacy-respecting solution that you prefer?
- texasbigdata 6y agoWell, privacy is a fundamental human right. Perhaps not doing anything is better than Adobes likely self serving solution.
- smt88 6y agoThat's why I asked about a privacy-respecting solution. I understand that an Adobe product is not that.
- rubyist5eva 6y agoI'm just going to say, if you don't think this _isn't_ going to be massively abused - take a look at what the CCP, or any authoritarian regime does really, to silence dissent. Don't have a good enough social credit because you shared an opinion somebody doesn't like one too many times? Intel and Microsoft will just remotely brick all your devices. > Is there a privacy-respecting solution that you prefer? Yeah, it's called being media literate, using my brain and being vigilant. I don't need Pat Gelsinger, Satya Nadella, Sundar Pichai, Shantanu Narayen, Tim Cook, Mark Zuckerberg, Jack Dorsey or any other power hungry jackass telling me what to think.
- jonplackett 6y ago> In order to bring its best single core performance to the desktop market, Intel had to redesign its 10nm product on 14nm, which combines the high throughput of the design with the high frequency of 14nm Is that just because they couldn't do it at 10nm? I thought the whole point of die shrinking was to get higher frequency, lower heat etc?
- rayiner 6y agoThat is the purpose, but Intel's 10nm process is a cluster--k in terms of execution.
- zerocrates 6y agoMy understanding is that they can't get things to work at 10nm at the high desktop frequencies they use at 14nm. I don't know if that's yield issues, instability, or what... probably a combination of those? My sense is that on laptop, the 10nm stuff is doing... okay. It sure seems like the hope is to limp along on 14(+++++) for a while longer and leap straight to a kinks-worked-out 7?
- tedunangst 6y agoThe article drops some hints that the 10nm parts aren't stable at desktop power levels. Normally process shrink -> reduced power -> more power budget -> higher frequency. The power savings gives you room to push frequency (and power) back up. But it's not working out for 10nm. They're more efficient than 14nm, but they can't spend the energy they're saving on performance.
- rektide 6y agoI'm just flabbergasted that Intel has Thunderbolt support integrated into it's mobile chips, but on desktop it's business as usual, left to motherboard vendors to implement Thunderbolt themselves with the normal slew of add-on chips. Super frustrating that desktop users can't expect modern connectivity. It should be on the chip, like mobile. Notably, one can take any old TB4 cable, connect two modern Intel laptops, and get a 40Gbps networking connection between them. Alas, only a couple rare desktops will be able to participate & do this, because for whatever reason this on-chip capability that Intel has was omitted on desktop. I was so excited to be entering an era of enhanced connectivity!! Not yet, I guess.
- onli 6y agoIntel still did not react properly to their new situation of being objectively worse than AMD. They lowered the prices a bit, that's all. Still trying to segment the market with locked processors, even introducing more limits on ram overclocking, and still refusing to honor warranty when enabling XMP. That's not a company that wants to compete, so I wouldn't expect big moves with regards to connectivity. Locked processors shouldn't be a thing anymore, ECC should be supported, motherboard chipset segmentation stopped, and it would be nice if the new processors wouldn't be set to 300W energy usage. With the right price Intel's processors would have a chance then even though they are slower. But like this - who would want to buy this? You are right to be flabbergasted, they should do things like integrated thunderbolt support to better the situation.
- outworlder 6y agoNowadays they change their sockets at a much higher rate compared to AMD. Since you have to replace the motherboard to upgrade to a newer generation, the door is open to move from Intel to AMD.
- wmf 6y agoI think Intel sees slots as mutually exclusive with Thunderbolt.
- AtlasBarfed 6y ago
- ACAVJW4H 6y agoSaddest thing is that even this stopgap meh CPU will be outsold and you'll wait ages to get it.
- ternaryoperator 6y ago*will be sold out "will be outsold" has a different meaning, (which is likely also true for this processor, but not what you meant)
- samfisher83 6y agoYou have to give whomever came up with 14nm process. Despite being super old it's still somewhat competitive. It's crazy Intel can't fix their process. They make more cash than amd, nvida etc. They make more cash than tsmc.
- Guthur 6y agoI would not be surprised if there was a lot of sunk cost fallacy on Intel's 10nm. They couldn't make it work effectively and it was so far behind that they bled out most of their process leadership. But rather than pivot and reset they've just kept hammering away at it. Of course the decision would not be trivial to make; the lead time for a new process node is significant.
- fshbbdssbbgdd 6y agoKnowing very little about the subject... Is it plausible that they wouldn’t be able to get 10nm to work, but would be able to make 7nm work? Or put differently, would abandoning 10nm be tantamount to abandoning the effort to develop a smaller process?
- deleted 6y ago[deleted]
- Guthur 6y agoI am a very causal enthusiast but from my understanding there are many ways to skin a cat when it comes to process nodes hence with the company A 10nm vs company B 10nm are not equivalent. Intel somewhere along the line chose the wrong set of solutions to achieve their 10nm process. IMO these mistakes will not necessarily mean that some other node will be inherently disadvantaged other than the fact that they may now find themselves scrambling for tech lead. They will still have learned a lot from 10nm and hopefully should be able to feed that into future density improvements.
- Hiopl 6y ago
- pantalaimon 6y agoBeaten by the 5800X in almost every test, unless AVX512 was used. Given the 7nm shortage at TSMC, Intel might still beat it in price / availability.
- menmob 6y agoFor 5600X/5800X, availability is fine now. They’ve been in stock at amazon for a few days continuously. 5900X and 5950X on the other hand.. good luck.
- ChuckMcM 6y agoI find it really amazing that one of the things "saving" Intel at the moment is that TSMC is maxxed out on 7nm capacity ATM.
- SloopJon 6y agoI really wanted to build a Zen 3 / RTX 30-something to replace my Ivy Bridge / GTX 1060. After months of chasing the RTX, I finally ordered a prebuilt yesterday with a 10700K / RTX 3080. Now to see if it really is "in stock and ready to ship." The only thing I feel like I'll be missing in the 10700K compared to the 11700K is AVX512. It's been derided for throttling, but it does look kind of amazing for certain workloads. One thing I find curious about the Zen 2 and Zen 3 product lines is that the processor I really want is OEM only: first the 3900, now the 5900. I like the idea of twelve cores at an easier-to-cool 65W. I bought an OEM Athlon back in the day, but I don't see a lot of OEM processors for sale these days. Maybe just more fallout from the chip shortage.
- dannyw 6y agoYou can just get a higher TDP processor and set limits so it's a low-TDP one. It will perform better. The most efficient CPUs go to the highest end parts; not the other way around.
- pengaru 6y agoBetween ECC and tsmc 7nm, amd will continue to eat Intel's lunch until they at least get past 14nm, this is getting pathetic.
- colinmhayes 6y agoAnyone have any idea when intel's 10nm will hit desktop? Are they making any progress at all? Are they just planning on skipping straight to 7 at this point?
- dogma1138 6y agoIn 6 months for the past 5 years.. Realistically now probably mid 2022 we’ll see something, but probably not a full lineup until 2023.
- wmf 6y agoAlder Lake-S is rumored for December 2021. The delays have cascaded so 7nm is still pretty far away.
- AtlasBarfed 6y agoThis is half- to full- snark: When they outsource to TSMC. At some point Intel will get their act together and only be one step behind rather than... christ, are they three steps behind? They just have way too much money. But it does look like with the management purges, re-hires of old guard, and other changes it'll be a while before they right ship. There's probably pride to overcome, since a lot of process choices probably are "stake my career" things and now those careers may be coming to an end. The interesting thing may be that Intel now not only must close a gap in process technology, they may also need to change instruction set and make an ARM offering.
- toast0 6y ago> At some point Intel will get their act together and only be one step behind rather than... christ, are they three steps behind? They're not really three steps behind. At some point, node measurements became more useless as Intel and TSMC differ on what part of the thing they're measuring. Intel's 14 nm is roughly the same as TSMCs 10, and i10 ~= t7, i7 ~= t5. TSMC is shipping their 5nm chips, and intel is halfway shipping their 10nm chips, so that's somewhere between 1.5 and 2 steps behind.
- 6y ago
- pdog 6y agoNo ECC support means it's totally useless for workstation workloads.
- jeffbee 6y agoThis wasn't ever going in workstations anyway. The part you want for that is Ice Lake.
- cbozeman 6y agoActually the part you want for workstations is Threadripper.
- wmf 6y agoPresumably Xeon E-23xx is coming but you'll still be better off with Ryzen Pro 5xxx.
- p1mrx 6y agoWith Ryzen, it's feasible to use ECC in a desktop/gaming PC too; you just need a motherboard that lists ECC support. I'm running DDR4-3200 CL22 ECC overclocked to 3666 CL16 on an ASRock board with a 5800X.
- loeg 6y agoYeah, this is likely the implicit comparison GP was drawing. Which ASRock board did you go with?
- p1mrx 6y agoB550M Steel Legend... I think it's the only AM4 microATX board with ECC, 2.5G Ethernet, and dual USB3 headers.
- esperent 6y agoIs there any advantage to using ECC for a gaming or desktop PC?
- floatboth 6y agoSame amount of L3 cache (16MB) as the good old R7 1700? I guess 14++++++++ doesn't fit more? :D
- ece 6y agoWould be interesting to see a 65W comparison.
- gautamcgoel 6y agoI didn't see any benchmarks if the new Xe iGPU. Wonder how good they are... 2x over previous generation wouldn't surprise me.
- aetherspawn 6y agoI bought one a few months ago and I can confidently say that the performance is fantastic (the integrated Xe graphics plays all manner of games at full settings and framerate), however the drivers are terrible. The particular laptop that I bought is the New Dell XPS 13, and it has an integrated 4K screen that randomly flickers, fails to start after sleep, dims and has a plethora of other issues related to power management bugs in the drivers that Dell have told me are a work-in-progress with the Xe. In the last month or so, there has been a new graphics driver or BIOS nearly every week, and insofar the issues are now nearly all resolved. As for the CPU, the i7-1185G7 runs really hot on idle but thankfully it doesn't get much hotter under extreme load. It feels absurdly fast, but the battery life is quite lackluster as you'd expect due to the heat produced under idle.
- jeffbee 6y agoStrangely it seems like the 35-45W Tiger Lake parts holds their own here. It doesn't feel like Rocket Lake needs to exist, if Tiger Lake-H exists.
- walrus01 6y agoI see nothing in this review that would make me choose the Intel part over a Ryzen 5800X.
- encryptluks2 6y agoPrice is the biggest factor. You can get 10 cores with Intel for cheaper than 8 with AMD, plus with Intel you get integrated graphics as well which is really important right now considering the GPU shortage. Also, Intel allows virtual GPUs for virtualization in QEMU which AMD won't do.
- moreira 6y ago“Choose Intel because it’s cheaper than AMD” is one of those arguments that make you realise how quickly the world changes.
- dwohnitmok 6y agoThe whole situation is a kind of surreal 180-degree turn of what things looked like 5+ years ago and a testament to how far AMD has come. "Yeah go with Intel if you don't need top performance because the CPUs offer more[0], but slower cores, albeit with much higher power draw and a decent-enough integrated GPU at a cheaper price point." Are you sure we're not talking about early 2010s era AMD APUs? [0]: There are as many caveats here as there were 10 years ago for AMD.
- redisman 6y agoIt does make sense though given that they’re still cashing in on their mature process when AMD is in the TSMC 7nm bidding war
- walrus01 6y agoIf I wanted more than 8 cores, the 12-core ryzen 5900X is $549, can you really get an intel 10-core cpu for the same price, or within 50 bucks plus or minus, that performs better? I'm seeing the i9-10900K for $467, but in terms of dollars/performance per core I think it's still behind the ryzen which costs $82 more. https://www.techspot.com/review/2132-amd-ryzen-5900x/ https://www.techspot.com/review/2132-amd-ryzen-5900x/
- intricatedetail 6y agoThis is pathetic. At this point Intel should open up x86 and become like ARM as this is proven to work now. I wonder how badly Intel's mishap set humanity back by releasing essentially the same processors each year...
- AtlasBarfed 6y agoWe're simply fortunate this monopoly was more easily cracked that ones like Microsoft.
- fctorial 6y agoAnd I should open up my sewage pieline and become like starbucks.
- tathisit 6y agoIntel and AMD superglued x86' bottom and gave it laxatives.
- css 6y ago> The improvements Intel has made to its processor seem to do very little in our gaming tests, and in a lot of cases, we see performance regressions rather than improvements. > The answer from our side of the fence is that Rocket Lake has some regressions in core-to-core performance and its memory latency profile.
- coding123 6y agoI think at this point we're just waiting for Windows and Linux to be fully supported on the M1 or for ARM to come out with a system on a chip that's documented enough for Windows and Linux to make a port.
- martinald 6y agoThere already are other SoCs for ARM based PCs. Qualcomm has the 8cx "Gen 2" chip, but it performs really badly compared to M1 (https://www.cpu-monkey.com/en/compare_cpu-qualcomm_snapdragon_8cx_gen._2-1849-vs-apple_m1-1804 https://www.cpu-monkey.com/en/compare_cpu-qualcomm_snapdrago...). Considering how little fab capacity there is for new designs right now (and Apple has probably booked it all out for months/years to come), I can't see this situation changing much. AMD is the closest but they also have insane supply shortages right now.
- kcb 6y agoOr just buy AMD.
- kllrnohj 6y agoWhy would you wait for that when you can have a faster CPU in the form of the 5800X today? The M1 is a phenomenal laptop CPU, but it's still not faster than AMD's desktop offerings, either. At least not according to the specint results in the article.
- jeffbee 6y agoThe M1 is much faster on some single-threaded workloads than any other CPU. For example on browser benchmarks M1 is a whopping 60% faster than the 2nd place processor. Browser is an important workload for most people. If you want to run MS Windows then obviously I can't recommend it.
- StillBored 6y agoYah, the M1 is a single threaded beast, but its too power constrained (and apparently not as efficient in a number of cases) to keep up with AMD's less power constrained laptop cores in throughput tests. I think this could be a fine battle with a strong apple lead at least until amd releases a 5nm design, but i'm afraid that apple, will be apple and keep doing thin/light/constrained devices, with maybe a super expensive mac pro that can't be justified by anyone who doesn't burn cash in their grill.
- StillBored 6y agoSad, 10 years of nothing from intel but single digit uplifts and increasing power. I think apple sort of proves that there is plenty of single threaded perf uplift available with the right designs (aka one not designed for a server). Even AMD traditionally trailing is easily surpassing them now too, the AMD core that is easily matching or beating them isn't even close to the best desktop part they have (and rightfully so, a desktop with 8 cores... lets see phones with 8 cores have been a thing for how many years again?). Couldn't happen to a nicer company, but for the health of the industry I hope they have something to keep up with the Arm hordes. What we need is a good decade of a 3+ way back and forth between an arm vendor or three and amd and intel to really push the industry again. BTW: Just imagine what apple could do with a 300W power budget!
- judge2020 6y ago> BTW: Just imagine what apple could do with a 300W power budget! We'll likely see by the end of 2022 (probably with less than 300w): https://www.theverge.com/2020/12/7/22158264/apple-32-core-processor-arm-mac-macbook-pro https://www.theverge.com/2020/12/7/22158264/apple-32-core-pr...
- nightski 6y agoYet they are still the king of single threaded performance (barely). I'm not so quick to rule out Intel, even if I have no love for them. While the M1 was extremely impressive from a power efficiency standpoint, I think the jury is far from out on whether Apple will be able to take those gains and scale them to serious computers.
- lukevp 6y agoWhere are you getting that they’re the king of single thread? That was true (barely) last gen of AMD, and is not true anymore. AMD is better at single and multi core as well as power efficiency. From the article: > Our results clearly show that Intel’s performance, while substantial, still trails its main competitor, AMD. In a core-for-core comparison, Intel is slightly slower and a lot more inefficient.
- gigatexal 6y agoLooks like Intel gets it wrong with higher latencies whereas the AMD part is a single chip let. AVX512 though screams on this chip.
- khyryk 6y agoGaming performance regressions leave me a bit stunned. That's impressively bad, even for Intel. What are they going to do now, price this below the remaining Comet Lake stock and hope that Zen 3 has low availability until they have Alder Lake ready?
- mentos 6y agoComplete layman here. What prevents Intel from reverse engineering AMDs hard work and offering a fast follow rip off?
- yoz-y 6y agoAmong other things: intel has an internal fab that they do not want to let go. This makes them several generations behind on the process. Even copying AMD arch would not help.
- mywacaday 6y agoWill this run MS Teams better, only half joking
