AMD Ryzen 9 3950X Review
- LatteLazy 7y ago7nm is about 35 times the diameter of a silicon atom.
- BubRoss 7y agoThat's interesting but to put it in perspective I need to know how it relates to a human hair or how many times it can circle the earth.
- awareBrah 7y agoAbout the length your hair grows in one second
- Koshkin 7y agoI am sure you meant one microsecond.
- shantly 7y agoIf I've used Wolfram Alpha correctly, a 7nm span of silicon circles the earth 5.4874958×10^-16 times at the equator.
- deleted 7y ago[deleted]
- codyb 7y agoI may be reading this wrong, wouldn’t a 7nm span of anything span the Earth 5.4874958x10^-16 times then? Or is this somehow different than a pound of feathers vs a pound of gold question? Edit: definitely glossed over the dead comment there this is in response to
- dewey 7y agoSorry but I only calculate in football fields.
- hkjhreiou 7y agoI don't know, I find it more relatable if put in terms of how high a stack of CDs would be or how many times we can write the Library of Congress on it.
- Filligree 7y agoOf an individual silicon atom, apparently. I'd think the "grid size" of silicon crystals might be more relevant, and that's not necessarily the same number... Hmm. 0.235nm between atoms, 1/30th of 7nm. (Though, precisely what does the 7nm number measure?)
- andy_ppp 7y agoNobody knows anymore, it’s kind of feature size, but everyone defines feature differently!
- mantap 7y agoIt seems like transistor density (N per unit area) would be a more useful measurement.
- gruez 7y agoIsn't that the logic behind the "fake" nanometer measurements? Let's say everyone is on "32nm", but you got a new process[1] that packs twice the number of transistors than everyone else, but with the same feature size. Essentially, your 32nm feature size process is equivalent to everyone else's 22nm feature size process. Are you going to advertise your new process as "32nm" which is the same as everyone else, or "22nm"? [1] eg. https://en.wikipedia.org/wiki/Multigate_device https://en.wikipedia.org/wiki/Multigate_device
- andy_ppp 7y agoI mean I'm no chip designer but surely they are using some crazy hacks like transistors that take up more space than the lines between them by being part of the substraight above and below the etched lines. And presumably they use interference/coherence to etch even finer details? There are probably about a million different techniques they use to pack in more transistors without making the process smaller.
- lm28469 7y agoIt sure is, but 7nm in cpu lithography doesn't mean anything, it's pure marketing. https://en.wikichip.org/wiki/7_nm_lithography_process https://en.wikichip.org/wiki/7_nm_lithography_process > The term "7 nm" is simply a commercial name for a generation of a certain size and its technology and does not represent any geometry of a transistor.
- api 7y agoYeah, since about 14nm the nanometer number has become kind of like CPU speed (mhz/ghz) became in the early-mid 1990s and for the same reason. Long ago you could say e.g. a 600mhz CPU was faster than a 500mhz CPU. Then things like instruction level parallelism and other significant optimizations started and you had lower-core-speed CPUs that would in practice be quite a bit faster than higher-core-speed CPUs. Today a 1.6ghz mobile chip is far faster than a 2.4ghz earlier generation Pentium-4 for example, at least for most workloads. My understanding is that chip fab processes have developed similar numbers of devils in details. It's not just about the smallest feature size but lots of other things like materials, transistor types, layout, power density, etc. I've heard that Intel's 14nm processes are comparable to other fabs' 10nm processes for instance. Still this 7nm node is better than what Intel is currently shipping.
- mc32 7y agoWe need a new “PR rating”[1] system for feature size to make some sense of these numbers being bandied about. [1]https://en.m.wikipedia.org/wiki/Performance_Rating https://en.m.wikipedia.org/wiki/Performance_Rating
- Nokinside 7y ago7mm is so called 'commercial name' nothing physical. Million transistors per square millimeter (MTr/mm²) is better comparison metric than the commercial name for the process. Here is handy chart I copied from https://www.techcenturion.com/7nm-10nm-14nm-fabrication https://www.techcenturion.com/7nm-10nm-14nm-fabrication: Tech Node name (MTr/mm²) Intel 7nm (2??) TSMC 5nm EUV 171.3 TSMC 7nm+ EUV 115.8 Intel 10nm 100.8 TSMC 7nm Mobile 96.5 Samsung 7nm EUV 95.3 TSMC 7nm HPC 66.7 Samsung 8nm 61.2 TSMC 10nm 60.3 Samsung 10nm 51.8 Intel 14nm 43.5 GF 12nm 36.7 TSMC 12nm 33.8 Samsung/GF 14nm 32.5 TSMC 16nm 28.2
- IanCutress 7y agoIt's worth pointing out that the value for Intel's 10nm is on its high-density libraries, not its high-performance libraries, which are less dense.
- Filligree 7y ago"Libraries"?
- KuiN 7y agoThere's a lot of detail in a really in-depth (but very interesting) AnandTech article about Intel's 10nm process [0]. The basic idea is Intel have multiple distinct sets of logical unit designs at different densities which have different characteristics. It's like having multiple software libraries that do the same thing but have different performance etc. except it's a library of silicon building blocks. You trade-off speed with density (highest performance library uses the least dense circuits). Each chip's design can be made up of bits of silicon from these different libraries. Different densities also have different power consumption, so in cases it makes sense to build low power chips that have small high performance, power sucking parts that can be used sparingly.

- 7y ago
- piinbinary 7y agoWhen GPUs became vastly more powerful over the last ~10 years, it made big neural nets practical. I wonder what an equivalent jump in CPU power will unlock.
- Scarbutt 7y agoMore electron apps.
- ralusek 7y agoOnly if people make more usage of worker threads.
- dkersten 7y agoNot faster electron apps, just more. One per core.
- adzm 7y agoThat's more of a memory bottleneck though.
- mantap 7y agoYeah indeed chromium is a more efficient 2D rendering engine than what's available natively and performance of JS is comparable to Java. Electron apps being slow is mostly a developer laziness problem, not a technology problem. Making a fast electron app is actually easier than making a fast C++ app IMO, when you take into account the libraries and tooling available.
- mrec 7y agoI think the difficulty is in making a lightweight Electron app, not a fast one. Games run fast too, but they can get away with hogging resources because they're typically the only app you're using at the time.
- neogodless 7y agoThis isn't the most groundbreaking release - it's not the first 16-core chip you can buy (edited), nor the first 7nm. No new clockspeed records were set. Still, $750 for all that power! Any professionals shopping for this, or waiting for 24 or 32-core Threadripper? Anyone trying to upgrade on an older motherboard, or are you getting a matching X570 to ensure maximum boost and PCI-e bandwidth?
- snagglegaggle 7y agoThe step from Ryzen to Threadripper is quite a big one. I'd benefit from a Threadripper system, but budget only allows a (top tier) Ryzen for now. I suppose spare money could go towards a Threadripper right now and I wouldn't consider it wasted per se.
- Tepix 7y agoEven if you can get a good price for the CPU, the mainboards are very pricey compared to the consumer CPU boards.
- penagwin 7y agoLast time I checked, motherboard's for thread ripper cpus were around 200~300$, is that still the case? The motherboard cost really erases the budget for entry, as that's the price of a decent ryzen cpu.
- snagglegaggle 7y agoExactly, and there's not a lot of used DDR4 (w/ or w/o ECC) on the market.
- jagger27 7y agoI would say it is the first 16-core "consumer chip", since every other 16-core chip has either been HEDT-class or server-grade, both requiring expensive motherboards. I would be happy to try plopping this into my B450 motherboard from my 2700X. I'm happy with my current NVMe storage, which is just about the only thing that takes advantage of the extra bandwidth. Graphics cards aren't there yet.
- zamubafoo 7y agoI find it interesting how desktop CPUs are essentially coming down to two enthusiast markets, developers/content creators/workstations and gaming. While the gaming market is (usually) seeking the highest top single core clock speed with respect to CPUs, it also relies on other expensive hardware. Meanwhile the dev/content creator/workstation market is much better served by these multi-core behemoths. Intel really has their work cutout for them with performance to cost for consumer desktops.
- CoolGuySteve 7y agoBefore Vulkan, there were more bottlenecks on multithreaded rendering. Most games pushed everything to a single drawing thread. Hopefully going forward that will change, but even with Red Dead Redemption 2's Vulkan implementation, a 6 core Intel/AMD chip is competitive with this processor at lower settings/resolutions where the GPU is less of a bottleneck. Compute bound games like Civilization 6 do scale with processor count however.
- swebs 7y agoFactorio is also limited by single core performance, with the developers saying they have no plans to implement multithreading.
- kuzko_topia 7y agoThis is unfortunate, and I'm saying this as an AMD owner and factorio player. Do you have a source for this?
- jsgo 7y agothat reminds me of what I had read on EverQuest 2. I downloaded it when it went f2p years after launch. My gaming PC had some issues with it which seemed nuts as it could handle more intensive games. After reading up on it, EQ2 came about a little bit before the shift to multiple cores which was to their detriment: they basically expected single core performance to keep going up substantially (as it had during EQ1 era) and not expanding to multiple cores. As such, they optimized against a configuration that never ended up existing.
- mrandish 7y agoI noticed yesterday's articles about Intel's upcoming unusually large release of security mitigations. Under serious competitive threat for the first time in a while, I'm curious if Intel may have slowed the release of some mitigations to land after this round of comparison benchmarks.
- Someone1234 7y agoThat's an interesting idea I didn't consider. edit: Below is wrong, see author of article's reply below for why. Preserving for record. They have been holding back review samples of their latest i9s so reviewers wouldn't do head-to-heads with this new 3950X (but people have anyway, and the 3950X crushes the i9). See Linus Tech Tip's review of the 3950X this morning for citation.
- neogodless 7y agohttps://linustechtips.com/main/topic/1123580-intel-could-take-years-to-catch-up%E2%80%A6-ryzen-9-3950x-review/ https://linustechtips.com/main/topic/1123580-intel-could-tak... For those of you without really good search engines :) (Contains link to YouTube video review.)
- IanCutress 7y agoThe new 18-core i9-10980XE isn't out yet, and review embargoes haven't been lifted. We know it's a slightly clock bumped version of the i9-9980XE, which was included in the AnandTech review and not the Linus review. Linus tested the 8-core i9-9900KS, which came out a few weeks ago, and those results are also in the link which is the title to this thread.
- greatpatton 7y agoYet the main question remain if the benchmark were done with the latest mitigation (and version of the microcode) or without...
- IanCutress 7y ago
- th-miracle-257 7y agoWhy did Apple not release their new MBP 16 with the 3950X? [1] [1] https://news.ycombinator.com/item?id=21523780 https://news.ycombinator.com/item?id=21523780
- Someone1234 7y agoThey're Intel based mobile systems. The 3950X is a desktop class AMD CPU.
- 3JPLW 7y agoBecause it's not a notebook chip? 105W is... a little toasty.
- HHad3 7y agoIn addition to the points already mentioned, a good bit of Apple's software depends on Intel-proprietary features, e.g. QuickSync for video encoding. So far, no macOS system ever shipped with an AMD CPU, and porting the OS and user-mode application stack is not trivial.
- neogodless 7y agoYeah, I don't think you need downvoted into oblivion for not knowing, but AMD mobile APUs are also not anywhere near this level. The top-end Ryzen 7 3780U is a 4-core multi-threaded part, using Zen+ rather than Zen 2, and the older Vega graphics. (And that's only available in a Surface laptop.) https://en.wikipedia.org/wiki/List_of_AMD_accelerated_processing_units#Mobile_APUs https://en.wikipedia.org/wiki/List_of_AMD_accelerated_proces...
- davidy123 7y agoSlight meta, and part of a larger 'rant,' but when are we going to get away from reviews that might as well have been printed on glossy pages in PC Magazine in 1986? Anandtech has been at it since the 90s and hasn't changed their format at all. This is a serious decades-long stagnation of the web. The graphs should be dynamic (able to choose what scenarios and components to compare, and able to search within them), and user contributed. Instead we get feeble excuses like "it doesn't make sense to compare a two-year-old-generation to this one," well yes it does if I'm considering an upgrade. Only a few sites support these options. Storage Review was an early leader but hasn't much moved much, Notebookcheck is another, and of course Phoronix.
- localhost 7y agoJupyter could form the basis of an interesting publishing pipeline for this kind of a review using various Python viz libraries. For user-contributed content, it would be interesting if you could "fork" an existing publication and add your own color to it. But somebody would need to pay for the compute and storage for this to work, as well as enable the kind of advertising / layout requirements that drive the business side of sites like Anandtech.
- lettergram 7y agoNot trying to be snarky, but: If you think that it’s be better - why don’t you make it? I suspect the current format is the way it is because it’s easier and “good enough”. I feel if you reach out to Phoronix you might get a response.
- davidy123 7y ago> If you think that it’s be better - why don’t you make it? Because I am already quite busy on other projects.
- whatshisface 7y agoDynamic JS graphs sound like a pain, I'm not a professional user of this specific website, and I don't want to learn a new dynamic interface for every website I visit. Sometimes I just want to look at a chart. User-contributed data would be of limited value on a website whose specific value proposition is that they know more about benchmarking than the average Joe. The pagination is annoying, though.
- Tepix 7y agoLooking at some benchmarks done by PC Games Hardware it appears that games are still not capable of taking advantage of 16 cores and 32 threads. It's not surprising - why would developers optimize for something that's not yet widely used. But I wonder when we'll get there...
- paulmd 7y agoConsoles determines how many cores game engines will be coded to use, and consoles are staying with 8C processors for another generation.
- oouiterud 7y agoI read that all these new AMD CPUs support ECC, but it’s been hard finding verification. Can any one recommended a motherboard that both supports and uses ECC RAM with this new CPU?
- Tepix 7y agoHere is a list of AM4 mainboards that support Ryzen 3000 and support ECC RAM: https://geizhals.eu/?cat=mbam4&xf=16791_R3000X%7E494_ECC-Unterst%FCtzung https://geizhals.eu/?cat=mbam4&xf=16791_R3000X%7E494_ECC-Unt... There's 107 of them, starting at 43 Euros.
- neogodless 7y agoSome useful links within: https://www.reddit.com/r/Amd/comments/cb8tyr/asus_pro_ws_x570ace_paired_with_ryzen_9_3900x/ https://www.reddit.com/r/Amd/comments/cb8tyr/asus_pro_ws_x57... ASUS Pro WS X570-Ace seems like the top dog here. https://www.anandtech.com/show/14161/the-amd-x570-motherboard-overview/39 https://www.anandtech.com/show/14161/the-amd-x570-motherboar... The conclusion doesn't point out ECC-compatible boards, but the comments mention the same Asus.
- boris 7y agoAnyone hopping to have ECC with Ryzen should really read the reddit thread. Wow, what a mess.
- fivefive55 7y agoIt seems like ECC support is pretty widespread, I know for a fact that my Asus Prime X570-PRO has an option for ECC memory in the bios and it's a midrange board. Might depend on the board manufacturer to enable it. Asus seems to have it in most if not all of their boards.
- bhauer 7y agoI am using ECC memory with my 3900X on a Gigabyte Aorus X570 motherboard. Works great.
- InternetOfStuff 7y ago
- cracker_jacks 7y agoWhere is the 9980XE @ $979 coming from in the price vs performance chart? Where can I get a 9980XE for $979??
- neogodless 7y agohttps://ark.intel.com/content/www/us/en/ark/products/189126/intel-core-i9-9980xe-extreme-edition-processor-24-75m-cache-up-to-4-50-ghz.html https://ark.intel.com/content/www/us/en/ark/products/189126/... Seems like it should be $1979 to match Intel's suggested pricing. (Retail looks like it's $1949 on sale, and typically even higher.)
- IanCutress 7y agoIntel has announced the Cascade Lake-X i9-10980XE coming out later this month for $979. It's slightly higher in frequency,
- neogodless 7y agoRight - I didn't notice a footnote. I just saw your comment / reply on the article. It's a fair label, just wasn't clear to me!
- stagger87 7y agoIntel recently announced price cuts for the 9th gen Skylake X series processors to match the upcoming 10th gen versions. I don't think resellers/vendors have caught up yet, this was only a few weeks ago. They pretty much cut the price in half for all of the processors in this category. I haven't seen them available at these prices yet anywhere.
- ibobev 7y agoAs a developer I am keen to see some compilation benchmarks. Unfortunately those kinds of benchmarks are almost never included in such reviews. Instead there are many gaming benchmarks which purpose is not exactly clear for me, after obviously gaming is not the primary target market for R9 3950X.
- mmastrac 7y agoI believe that some of the YouTube channels have started including compilation benchmarks. GamersNexus [1] and Linus Tech Tips [2] both do! [1] https://www.gamersnexus.net/guides/3460-new-cpu-bench-methodology-workstation-program-compile-tests-premiere https://www.gamersnexus.net/guides/3460-new-cpu-bench-method... [2] https://youtu.be/stM2CPF9YAY?t=4m49s https://youtu.be/stM2CPF9YAY?t=4m49s
- simplyinfinity 7y agoIn addition, Level1Techs is more developer/sysadmin oriented than consumer oriented : https://www.youtube.com/channel/UC4w1YQAJMWOz4qtxinq55LQ https://www.youtube.com/channel/UC4w1YQAJMWOz4qtxinq55LQ
- polivka2 7y agoAnd in addition to that, we have Open benchmarking and Phoronix for that. :)
- velox_io 7y agoLikewise (I 2nd L1Techs btw). Having 16 cores/ 32 threads will greatly aid testing server applications. Making multi-threading & locking issues much more apparent (Amdahl's law) than they would on a slightly older CPU with only 4-6 cores (a i7 6700k in my case).
- sbov 7y agoNote that the GamerNexus review of the 3950x didn't include their compile benchmark test, at least on Youtube.
- 7y ago
- wayneftw 7y agoAny problems with AMD cpus and containers or virtualization? (Really? Wow. Sorry for asking a question!)
- neogodless 7y agoI only have limited experience so far, but I was able to enable virtualization and run WSL on Windows 10 with a Ryzen 7 2700X with no obvious issues. I'm sure more in-depth, longer term container testing would be more useful to you, though!
- jmkni 7y agoSame with a 3700x. Running an Android Emulator, Docker, and WSL2 on Hyper-V simultaneously with no obvious issues.
- pb82 7y agoI'm running Kubernetes inside a libvirt VM on a Ryzen 3600. No issues at all.
- wayneftw 7y agoThanks to you and others for your data. I look forward to building my first AMD rig in like 15 years or something! I got an RX580 GPU just sitting around, from when I planned to upgrade my 2012 Mac Pro to support Mojave (not worth doing I decided). Now I just need the rest of the machine!
- Bayart 7y agoNo problem on my side of things running Docker at home on an R5 2600. I heard there were a few problems with IOMMU in the beginning but it should be long gone. Considering AMD's getting into the server market pretty convincingly I don't think you'll have issues on the sysadmin side. If you've got any problem it's gonna be from dodgy BIOSes and half-compatible hardware, the kind of stuff you might get running an older AM4 motherboard.
- fock 7y agoCan anyone comment on the IOMMU-grouping on typical boards? From what I've just googled, the CPU "lanes" seem to support ACS so it could indeed be working to replace my IGP+GPU-for-the-gaming-VN-Haswell system with a dual-GPU-Ryzen one (contrary to what I believed previously). Have been eyeing TR for that reason, but as I don't really need this amount of I/O (and cores), I might be well served by AM4.
- stamps 7y agoI don't have the exact grouping on hand, but I'm able to run a Ryzen 2700x (8 core) with a 2080 (Windows VM GPU) and wx4100 (manjaro host GPU) all on a GIGABYTE X470 AORUS GAMING 5. USB passthrough with an Startech USB PCI-E card was a bit problematic as the group was not isolated. Turned out the 2080 has a USB controller for the type C (I'm told for VR).
- bootloop 7y agoI am finally running a Ryzen 1700 + dual GPU system so I could get rid of dual-booting: CPU: AMD Ryzen 7 1700 Mainboard: GA-AX370-Gaming K5 (Bios: F25) GPU (Host): Gigabyte GeForce GTX 970 GPU (Guest): Gigabyte GeForce RTX 2060 OS (Host): Arch Linux OS (Guest): Win 10 As said it appears to me IOMMU grouping depends a lot on the board used. For mine it looks like all the chipset external PCIes are in one group and the CPU PCIes (basically the 16x for GPUs) are in two seperat groups. So I run two GPUs on 8x on each slot now. I was also able to pass through an USB 3.0 on-board controller as it was also in it's own group. But there is the ACS patch so you are able to pass through single devices which are in a physical IOMMU group (not only cpu lanes). I don't have personal exp with it tho. Warning: There are issues with the latest Ryzen gen and bios updates and they break vifo.
- paulmd 7y agoGamersNexus really hammering AMD's deceptive marketing around boost clocks. The only time it can hit its advertised boost clocks in when it's in the menu and you have near-zero load, and it barely touches it for an instant. Under even a single-core load it's failing to meet its advertised spec. There was a lot of hubbub around this with the initial release, AMD released a BIOS which they claimed fixed this, looks like it still has not. https://www.youtube.com/watch?v=M3sNUFjV7p4 https://www.youtube.com/watch?v=M3sNUFjV7p4 The performance is good enough as it is, no need to lie about it being 200 MHz higher than it can actually do. But here we are again 6 months later and AMD does it again...
- nolok 7y agoWhich is weird because they have the performance. Showing the perf of the processor does all the marketing it needs, no matter what clock it's running at, and with normal/turbo clocks customers don't even get it anymore anyway, so I don't understand why AMD is handicapping itself like this in the marketing department.
- mackal 7y agoThe issue sems to be that the max advertised boosts is based on the number the plug into the boost algorithm. (I say based since some of them, especially higher end chips are 25-75 MHz higher than advertised boosts, a BIOS Dev posted them somewhere that I can't find :/) There is an issue when the chips don't really hit it.
- vondur 7y agoAs far as I can see most of the reviews have mentioned how the 3950x is able to hit the advertised boost, so it looks like AMD is paying attention.
- gameswithgo 7y agopeople want big boost clocks which is dumb. they got them (when under no load) which is dumb. seems everything is fine.
- NKosmatos 7y agoWay to go AMD! One of the benefits of competition between the duopoly. AMD has cornered Intel these last couple of years and I don’t see this trend changing soon, not with all these vulnerabilities that chipzilla is having ;-) One thing I’d like to note, is that with all this computing power being available to users at a relatively affordable price, software developers (games - commercial software) won’t optimize their code. I’ve seen it happening where a loop/scanning/sorting algorithm won’t be optimized since the user will anyhow have a few cores and GHz to spare.
- rafaelvasco 7y agoWent with AMD with my latest build. Last time I went with AMD was back in 1999 with an AMD K6-2 500mhz.
- ArlenBales 7y agoI think the last time consumers were swarming AMD for their CPUs was Athlon 64 X2 around 2005.
- tracker1 7y agoBeen waiting for this for about a year now... pulled the trigger early on an X570 build as my old system (i7-4790K) was acting up and bought early. Been running an r5 3600, but replacing cpu with a 3950X.
- mtarnovan 7y agoI'm very curious how this CPU performs for Elixir compilation.
- Bayart 7y agoCompilation should profit pretty linearly from more cores thrown at it. Considering the Erlang VM is very concurrency-conscious it should be a pretty natural fit. But I'm not at all in on the intricacies of it, are there any particular CPU features (instruction set or module) it's known to take advantage of ?
- mtarnovan 7y agoYou mean like vectorized instructions and such? I don't know, but if I had to guess I'd say no. Anyway, I'm sure there are some compilation phases that won't benefit from more cores, but the bulk of the compilation seems to do so. Even though Elixir has incremental compilation, due to use of metaprogramming in the Phoenix framework sometimes even changes to a single file will trigger recompilation of hundreds of others, so I was thinking these new AMD CPUs with lots of cores could be very helpful here.
- Bayart 7y agoTry to ask around Stack Exchange or whatever, I'm certain some people have been running the BEAM on the second generation Threadripper chips (this one being pretty much just a better 16c Threadripper on a consummer socket) since they've been so popular for productivity/compilation.
- lliamander 7y agoIndeed, the only compiler benchmark one typically sees are for C/C++. But Lots of developers use other languages, and it would be nice to have a cross-section because each language is so different. BTW, how much does elixir benefit from multiple cores for compilation?
- mtarnovan 7y ago
- seminatl 7y agoI don't really get how they reached their conclusion. It seems like on most of the tests this new part gets beat by a cheaper one from Intel. It seems like a kinda unfair approach to use handbrake without AVX-512 support? Also not sure why they include the 3-d particle thing without AVX ... I guess because Intel is just too fast on that? If you look through the results, the things most people want to do with a computer, like browse the web and start their applications, are noticeably faster with the Intel i9-9900K at half the price. And the only game where the CPU makes a difference in these benchmarks is also a lot faster with the Intel part.
- gameswithgo 7y agoavx2 performance between the new amd cpus and intel is comparable. ive done some detailed comparisons with my own code that is tuned for intel and the ryzen is quicker in some places, slower in others.
- seminatl 7y agoAVX-512 is not AVX2.
- gameswithgo 7y agoI'm pretty well versed in the SIMD instruction sets, thank you. You might surmise that from the fact that I'm writing and benchmarking SIMD code.... I was responding to: "Also not sure why they include the 3-d particle thing without AVX" in which the op was not clear which AVX instruction set they were referring to. It seemed to be a difference benchmark from the one which had avx-512 disabled, due to the word "also"
- seminatl 7y agoSo aside from your irrelevant comments about AVX2 being about even between the two parts, what is a reasonable explanation for the second chart on page 4 of the article, assuming you can bother yourself to go read it. Their analysis seems to be essentially that if the Intel part wasn't 300% faster, then the AMD part would be 15% faster. But it is a fact that the Intel part is really three times faster on this benchmark, because of AVX-512. The only reason to include the chart with AVX disabled is to fit the article into a prejudiced narrative.
- ArlenBales 7y agoI wish the reviews that included gaming benchmarks would have included Monster Hunter World. Capcom's MT Framework game engine is extremely multi-threading capable.
