AMD Ryzen 9 7900X / Ryzen 9 7950X Benchmarks Show Impressive Linux Performance
- djha-skin 4y agoFun seeing performance reviews of new chips coming out. It's a sign to me that the market is recovering after the pandemic. Imagine someone promoting a chip during the pandemic, when you couldn't get them for love or money. Still, I would have liked to see a graph or other pretty chart showing the results of the benchmark off better so that I could internalize them easier.
- Bilal_io 4y agoThe embargo is going to be lifted later today on reviewers
- pedrocr 4y agoThese reviews came out normally during the pandemic. Here's the same review for the previous generation, released in November 2020: https://www.phoronix.com/review/ryzen-5900x-5950x https://www.phoronix.com/review/ryzen-5900x-5950x
- dschuetz 4y agoDoes the 7000 series have Pluton? Can't find specifics anywhere.
- nicolaslem 4y agoI don't know but for what it's worth my main machine is a 6000 series laptop (with Pluton) running Linux and I did not have any compatibility issues. Sure, it sucks to have some Microsoft designed hardware in my CPU but at least it not causing issues (for now).
- anonym29 4y agoYou have two ring -3 coprocessors with unrestricted DMA, unrestricted disk I/O, and unrestricted access to your network interface. One belongs to the NSA, the other to Microsoft. Do some traffic analysis on the upstream end of an ethernet cable plugged into that computer while it is hibernating or sleeping some time, you might not like what you what you find.
- YakBizzarro 4y agoany reference to that? I would like to read more
- anonym29 4y agoReference: I've done it on my own system. I'd encourage you to do it on your own system if you're curious.
- bruce343434 4y agoI don't have the hardware for it; what did you find?
- anonym29 4y agoWithout divulging too much information about the specifics, a LOT more traffic than I was expecting or willing to tolerate.
- bruce343434 4y agoSuch as?
- anonym29 4y agoSuch as outbound traffic that should not have been taking place. Like I said, not divulging more info. If you're skeptical, just try it.
- anonym29 4y agoZen 4 (Raphael) desktop CPUs will have it. Right now, Zen 3 (Chagall) and Zen 4 Threadripper (Storm Peak) don't currently have plans for integrating it, but that may be subject to change. I cannot provide proof, but I sure as hell am never buying Zen 4 or later AMD Desktop CPUs ever again for a system that will be connected to the internet.
- dschuetz 4y agoI would not go that far saying I won't buy AMD ever again, but if Microsoft has a foot in the door inside my systems in form of creepware like Pluton it is there for keeping the door open.
- anonym29 4y agoI edited to clarify. I would consider using them on a system that never gets connected to the internet.
- adrian_b 4y agoI am also paranoiac about such things, but the part with avoiding the connection to the Internet is easy for a desktop computer, if it also does not run Windows, where you never know what services might be active and with which external servers they might try to communicate. I have a small computer that is used as the router for the Internet connection and on which I have complete control over the firewall and over the proxies used for connecting to the Internet, so there are no chances for an unwanted connection to the Internet. For additional protection, one could run the Internet browsers in a Virtual Machine, to be absolutely certain that there is no way for a script run by the browser to access the physical hardware, assuming that you do not trust the sandboxing capabilities of the browser.
- anonym29 4y agoVMs are an imperfect solution to preventing programs running in the guest OS from affecting the host OS (imperfect, as VM escapes are a thing). VMs do not provide protection to the guest OS (or it's processes) from inspection and snooping by the host OS, or from inspection / snooping by the hardware the host OS is running on. If using a bare metal hypervisor, sed 's/host OS/hypervisor/g'
- est 4y agoStill waiting for the rumored 6700G with 12 RDNA2 CUs.
- dis-sys 4y agobased on what I heard from insiders, two batches of reviews for AMD's new chips, those released now are the ones from sites traditionally happy to provide overwhelmingly positive reviews, those going to be released tomorrow are the ones which usually provide more balanced reviews. good PR tricks - they just sign NDA agreements with different reviewers with slightly different embargo lift dates.
- Tepix 4y agoHeise Online has released their review (alas, behind a paywall) and it starts very positive. I'm pretty sure they are the most trusted reviewers in the german language.
- pedrocr 4y agoThe Anandtech review is also out. I had them as pretty balanced at least in the past.
- dis-sys 4y agosurely Anandtech is in a different category - why would the PR dept of AMD or Intel mess with Anandtech. sadly, the same can't be said for hundreds/thousands other much smaller reviewers.
- hipnoizz 4y agoAs this specific review is from Phoronix - do you have some proof that their reviews are (heavily) biased? I'm looking at reviews in more details only when I want to buy something, other than that I skip them or just have a quick look. I haven't did any serious comparison either, but I remember Michael Larabel from Phoronix criticising various parties. Many of his reviews are basically measures/benchmarks with some summary on top of that - his benchmarking methodology may be or may be not flawed, I don't remember him shilling for AMD. AMD has probably some goodwill from the Linux community since they open source or provide various specs for their graphics card. At least that used to be the case.
- cesarb 4y agoI recall that back in the 90s, besides higher clock speeds, one of the greatest reasons for excitement about a new CPU was instruction set extensions (MMX, 3DNow, etc), which could give outsized performance gains when software was updated to work with them. This latest release from AMD has similar cause for excitement: AVX-512 is more than just larger vectors, it also doubles the number of registers, adds per-lane mask registers, and other enhancements; unlike with Intel processors, there should be no worry of slowing down the clock for the whole processor when using these instructions with larger vectors, and unlike with Intel, we can reasonably expect that every AMD processor from now on will always have these instructions enabled.
- Scene_Cast2 4y agoI'm personally curious about AVX512 support in pyTorch and numpy. Numpy depends on BLAS libraries for performance, and I don't know how much dev resources are behind openBLAS (i.e. how soon I can expect performance increases), especially given that AMD is a much smaller company and doesn't spend as much as Intel on software.
- michaellarabel 4y agoMany AVX-512 Zen 4 benchmarks here - https://www.phoronix.com/review/amd-zen4-avx512 https://www.phoronix.com/review/amd-zen4-avx512
- timeu 4y agoInterestingly even software (oneDNN) that is using Intel's brand new OneAPI is running excellent one Zen 4 CPUs, often faster than on Intel's own CPUs: https://www.phoronix.com/review/amd-ryzen-7900x-7950x-linux/16 https://www.phoronix.com/review/amd-ryzen-7900x-7950x-linux/...
- devwastaken 4y agoCache sizes are also significant in these gens. The 5800x3D outperforms the 12900KS in many games. They just stuck a bunch of cache onto the 5800.
- AshamedCaptain 4y agoI really wish that someone would review CPUs at similar power levels, rather than TDP when there is a big difference between the two models. Also, there is no idle power comparison, something that may also differ significantly and affect Linux.
- devwastaken 4y agoWhat would be the purpose? If you want to purposefully limit power you're forcing the chip to underperform. You can just get the lower cost chip that does run at that power. For example the 5600x being 76W versus the higher chips.
- fomine3 4y agoIt's not the same. Many core on lower frequency is efficient than fewer core on high frequency, even if TDP is same.
- pizza234 4y ago> What would be the purpose? If you want to purposefully limit power you're forcing the chip to underperform The rationale is that each architecture has a sweet spot consumption/performance, and increasing performance over a certain threshold has increasing costs (AFAIK, one significant factor is the increase of voltage in order to push frequencies higher). I don't know the numbers, but AMD has been offering the 65W threshold for a while, so it can be reasonably assumed that 65W is the sweet spot performance/consumption. The reason for not buying directly a cheaper model is the number of cores - one may choose, say, a 65W-throttled CPU with 16 cores over an unthrottled 8-cores (in some scenarios, this can make sense).
- Kerrick 4y agoIn addition to this, you can choose to run your top-of-the-line multi-core processor in eco mode most of the time, and then consciously turn it back to stock settings when you know you'll need the extra speed/throughput, only bearing the extra heat and cost of that performance when you really need it.
- Tepix 4y agoCan't wait for the 65W, 45W and 35W Ryzen 7000 CPUs/APUs. These 100+W CPUs are a step backwards.
- doikor 4y agoYou can run it in 65W or 105W Eco mode. It will get the power consumption down a lot. Single thread performance will be the same and in multi thread it will still beat 12900K even in 65W Eco mode. https://youtu.be/uks4qQ2MXrM?t=1087 https://youtu.be/uks4qQ2MXrM?t=1087 https://www.anandtech.com/show/17585/amd-zen-4-ryzen-9-7950x-and-ryzen-5-7600x-review-retaking-the-high-end/20 https://www.anandtech.com/show/17585/amd-zen-4-ryzen-9-7950x...
- Tepix 4y agoSure but i'd rather signal to AMD (with my wallet) that I appreciate their lower power budget CPUs.
- sliken 4y agoI was impressed the 7950 did so well at 65 watts, 81% of the perf at 38% of the power. I'd expect the lower end chips with less cores to have even less of a compromise to get to 65 watts.
- INTPenis 4y agoI'm a life long Linux user, it's not even a thing for me it's just what I've used since my teens. But phoronix saying something has good benchmarks in Linux means absolutely squat to me. That site _always_ has good performance metrics on Linux. I do some gaming and I can tell you their posts never reflect my reality.
- m463 4y agoIsn't this so you as a linux user can decide if purchasing a specific cpu will make a difference?
- INTPenis 4y agoNot Phoronix, all my experience with them is just extremely good performance on Linux and always worse performance on Windows. The whole site seems to be written and edited by one dude. That's why I prefaced by saying I not just love Linux, it's all I've known for over 25 years. So I have every reason to be biased, but even I think there's something shady with phoronix.
- hassanahmad 4y ago95c and that power draw are a skip 7000 series for me. I think a used 5950x will be the sweet spot soon.
- bryanlarsen 4y agoAccording to other reviews, the 7000 series destroys the competition (both Intel and 5000 series) at 65W. Also, 7000 series is designed for 95C. It'll run forever at 95C, and will always run at 95C if it has the workload and power budget. IOW, giving it more cooling will cause it to run faster rather than making it cooler. On other chips 95C might indicate it's on the edge of failure, but AMD asserts that 95C won't shorten the 7000's life.
- bearjaws 4y agoRyzen scales up exponentially in power draw as you try to hit peak frequency numbers. You can run it at 95% speed and usually something like 70% voltage. My 3900x can do around 4.5ghz at 1.4v or 4.3ghz at 1.05v all core. I imagine Zen 4 will be exactly the same. Don't have the power draw off the top of my head, but that is essentially 125w for 4.5ghz and 90w for 4.3ghz.
- blibble 4y agofor FETs the power draw on voltage is quadratic (not exponential)
- mhh__ 4y agoIt's not going to get any better, you can thermal throttle it if needs be.
- Salgat 4y agoJust because it lets you run that hot doesn't mean you're required to. Just use the eco mode and enjoy still having high performance at lower power.
- mhh__ 4y agoNot as much better than alder lake than I was expecting
- didgetmaster 4y agoDoes anyone know how to apply to be a 'reviewer' for pre-released CPUs from AMD or Intel? I am building a new kind of data management platform that is highly threaded so it can do DB queries or other data manipulation functions in parallel. I will benchmark it against other common systems like Postgres (https://www.youtube.com/watch?v=OVICKCkWMZE https://www.youtube.com/watch?v=OVICKCkWMZE) but I only do that when I upgrade my own personal desktop or laptop. I would love to get my hands on loaner hardware to run benchmarks and publish them.
- pella 4y agoYou should add your benchmark to the https://openbenchmarking.org/ https://openbenchmarking.org/ And then there is a greater chance that phoronix will include it in its tests; or others will run it and publish the results.
- didgetmaster 4y agoThat would only really work if I already had the hardware for a meaningful benchmark. Right now my desktop has a 5950x and my laptop has a 6700hq. Showing a benchmark between those two systems would not be that interesting. I would like to show how my system performs on a 7950x vs my 5950x but I don't want to go out and buy another $2000+ computer just to get those numbers.
- pella 4y agoThis is a Clickhouse aggregated benchmarks : https://openbenchmarking.org/test/pts/clickhouse https://openbenchmarking.org/test/pts/clickhouse so everybody can verify and compare the results. If you create a benchmark; everybody can run .. and you can ask your networks for run this public test and upload the results. On the other hand you can wait for ZEN4 Epyc ... and rent for 1-2 hour in a cloud.
- nwmcsween 4y agoPlease give me a Frequency/Power chart so I can tell what if there is any wackiness WRT TDP.
- alkonaut 4y agoIt’s annoying when hardware sites compare new CPUs to a big list of older or less capable ones, but precisely all of them are basically so new that if you have one of them you probably aren’t upgrading now. If you have Ryzen 2/3/4 or 9/10th gen Intel you have to guess what kind of performance leap you’d get with this.
- Arrath 4y agoYeah I'm in this boat with a 9th gen Intel but I can approximate based off the 10th gens listed in the reviews.
