Does Matlab perform well on AMD Ryzen?
Out of curiosity I decided to benchmark my own matrix multiplication function versus the BLAS implementation I was to say the least surprised at the result:. They provide a free download version. Level 1 defines a set of linear algebra functions that operate on vectors only. These functions benefit from vectorization e. Level 2 functions are matrix-vector operations, e.
These functions could be implemented in terms of Level1 functions. However, you can boost the performance of this functions if you can provide a dedicated implementation that makes use of some multiprocessor architecture with shared memory.
Level 3 functions are operations like the matrix-matrix product. Again you could implement them in terms of Level2 functions. This is nicely described in the book. The main boost of Level3 functions comes from cache optimization. This boost significantly exceeds the second boost from parallelism and other hardware optimizations. I am not exactly sure about the reason, but this is my guess:. The new and ground breaking paper for this topic are the BLIS papers.
They are exceptionally well written. For my lecture "Software Basics for High Performance Computing" I implemented the matrix-matrix product following their paper.Intel's overclocked configurations also use DDR This feature debuted with the first-gen Threadripper processors to improve gaming performance and ensure compatibility with some games.
AMD says this feature largely isn't needed anymore, although there are a few titles that aren't compatible with the copious helping of threads. Far Cry 5 notoriously struggles with high core counts, and we also noticed abnormally low performance and outwardly rough gameplay in Dawn of War: Warhammer.Lga 1151 quad channel
The second-gen Threadripper models still suffer from the same odd performance in games if we leave all cores active, so we tested the Ryzen Threadripper WX and WX in game mode for all gaming tests. Given Threadripper 's high-priced nature, we fully expect these processors to be paired with high-resolution QHD and beyond displays. However, in keeping with our standard practice, we test at the FHD resolution to eliminate graphics-imposed bottlenecks.
Be aware: These deltas will shrink at higher gaming resolutions. The 3DMark DX12 and DX11 tests measure the amount of raw horsepower exposed by the processor to game engines, but most game engines don't scale as linearly with additional compute resources.
The DX12 tests expose the huge step forward with the Threadripper as the chips easily outpace their predecessors. However, Intel's new flagship turns the tables after overclocking. The DX11 tests also don't scale as well with additional cores, though we do see the expected gains with overclocking. The top of these charts used to be Intel-only territory, but AMD has made amazing gains in per-core performance a mixture of IPC and frequency with the Zen 2 microarchitecture.
Despite its hefty core counts, the Threadripper X features the same boost clock as the X, but it's premium silicon might be able to attain those boosts and stay at those heightened speeds for longer periods. Here we can see the X beat the X, if only by the slimmest of margins, and also experience additional uplift from the auto-overclocking feature. Intel's HEDT chips trail at stock settings, but once again take the lead after tuning.
This engine is designed specifically for many-core chips and scales well up to cores, which is music to Threadripper's ears. At stock settings, the X leads convincingly while the overclocked WX struggles to keep pace. The X once again doesn't see much uplift from overclocking, but it effectively ties the WX at stock settings. Keep your eyes on the previous-gen Threadripper models as you flip through the charts. AMD's explosive gen-on-gen performance improvement, borne of a new architecture and manufacturing process, is impressive.
Ashes of the Singularity: Escalation responds well to extra cores and threads, which benefits the Ryzen lineup. However, the condition is repeatable and carries over to the overclocked configuration, too. As we can see, this results in a lower 99th percentile frame rate, but that same trend applies to the WX and the XE.
We theorize this stems from Intel's mesh architecturepresent only on Intel's HEDT and data center processors, which can negatively impact performance with unoptimized software. Overclocking helps, but the XE at 4. The overclocked WX blasts to the top of the chart but its 99th percentile frame rates trail the X. Meanwhile, the Threadripper processors are a solid generational step forward.
As you can see at the bottom of the chart, the second-gen Threadripper chips aren't the best solution for gaming due to the eccentricities of their multi-die design.
In contrast, Threadripper beats the stock Intel processors. The Civilization VI graphics test finds the stock Ryzen 9 X delivering excellent performance given its price point.
That reminds us that these HEDT processors aren't the best fit for gamers — most enthusiasts are better served by mid-range and high-end mainstream chips. Intel's overclocking advantage comes into play once again, with the Core iXE taking a convincing lead.Of course, one can easily download an MKL binary with JuliaPro, but then you may have to face down an army of dependency conflicts.
Lots of performance comparisons are already out there, but I figured I would add one without an intel chip. Results are probably different with an Intel processor, eg probably this.
I just wiped my hard drive and installed a fresh x ubuntu Ubuntu I just used sudo apt-get install for the remaining dependencies.
All I recall installing was build-essential not sure if this included anything relevantm4and pkg-config. Otherwise, you can skip the Make. The end result:. I remember needing parallel studio to satisfy some dependency I believe it was libimf months ago, so I just went ahead and downloaded it today seeing if things could work without it. Therefore the new, Make. Below are the results using the same commit of Julia-master v0. Julia v0. Triangular x General Matrix Multiplication I figured rather than calling gemm!
Also, because StaticArrays performs poorly here, I wanted to add a different Julia function for comparison:. This is a naive algorithm and scales very poorly, but it is still faster for 8x8 matrices and in the same ballpark for 64x Here, MKL maintained its edge.
IterativeSolvers is essentially just sparse matrix multiplications so it would nice to test those.

Methods for extremely large matrices are the same iterative solvers just setup with a parallel implementation of the matrix multiplication, which in Julia could in theory be done by the array type so IterativeSolvers. Here is the gist from a few months back I was thinking of, where the Julia implementation was faster at symmetric eigendecomposition up to x or 35x35 matrices, depending on the computer. Here, Julia was faster until roughly x With 32 threads, MKL took 6. Thanks for doing this. It would be great if you could make a few graphs to summarize the results.
If someone could arrange some set of benchmarks for AMD vs. The Ryzen 7 and the i7 K or i7 are in the same ball park. Most of the benchmarks and random things I do are single threaded, but more serious things where time matters more than just a game are more likely to be parallel or threaded. As in all his benchmarks, Clear Linux dominates more often than not. And this is true on both AMD and Intel hardware. Which is cool because Clear Linux, like a lot of the fastest software, is made and maintained by Intel.
I should get around to more benchmarks and graphics.AMD's China-Only Ryzen 5 3500X CPU Review: 6C/6T Zen 2 vs. 3600, 2600
I have a new Ryzen CPU and ran into this issue. If a numpy version using openblas is used, then it's much faster. The above example is in ubuntu but I need to achieve this in windows as well. To be more specific I actually managed to install numpy with openblas but as soon I I then try to install anything on top like scikit-learn it will "downgrade" to mkl again. What I'm looking for is install instructions for a "scypi stack" python environment on windows using openblas?
This issue seems to be extremely annoying. While there is since not very long a nomkl package also for windows it doesn't seem to take as it always installs mkl version regardless.
Even if I install from pio, conda will just overwrite it, with an mkl version again next time you install something, in my case another lib which requires conda. As far as I can tell for now the only "solution" is to install anything scypi related from pypi pip : numpy, scipy, pandas, scikit-learn possibly more. Performance with mkl is restored and a bit better than with openblas. I did a very basic test see the link above with a fixed seed and the result is the same for mkl and openblas. Learn more.
Anaconda numpy scypi stack perfromance on Ryzen and windows Ask Question. Asked 5 months ago.
Active 5 months ago. Viewed times. EDIT: This issue seems to be extremely annoying. EDIT2: As far as I can tell for now the only "solution" is to install anything scypi related from pypi pip : numpy, scipy, pandas, scikit-learn possibly more. Maybe this helps. I did find that but seem unmaintained and hence not sure it has an upgrade path.
I will try this out on my ryzen system once I get the chance. This would help a lot. The only other option is to either use conda-forge but scipy still needs to come from pip or not use conda at all or switch to Linux. Active Oldest Votes. Sign up or log in Sign up using Google.

Since Anaconda now comes pre-packaged with MKL which is slow on AMD CPUs, what is the best way to setup an Anaconda environment with openblas, and link numpy and scikit-learn, while keeping all other packages the same?

Seems like there's no scipy in conda-forge without mkl see github. So I'm going to try github. Are you on Windows? That wasn't clear from your question Active Oldest Votes.

Find more results in the link below. RejZoR How does it compare to Intel's compiler since most use that only? Who uses icc on linux with ryzen? I'm not asking for Linux specifically, I was asking how specific compilers for Ryzen narrow the gap which Intel's creates on purpose? Did you somehow read a different article on Phoronix then I did? In a few cases AOCC was faster, but it was generally about three percent or less.
In some benchmarks, the Clang 5. Interesting, how you came to a totally different conclusion. What a non-news. R-T-B They barely improve over what they patched. Not impressive. Maybe it exposes some Ryzen-specific features and scheduling?
I would hope. Those initial results don't show much performance gain unless they basically didn't utilize something similar to that. Except when it's not an improvement. Read the original article, with a couple of exception, this compiler always falls between clang and gcc. Sometimes clang produces faster code than this, other times gcc beats it. This compiler wins in exactly one benchmark, but at the same time it also finishes last once. I don't think they would bother if it didn't improve something I refer to BTA's post Maybe Ryzen specific features and scheduling Horrible results I must say :.
Horrible results I must say : I went back to the article and counted: it beats gcc in 5 tests and looses to gcc in 3. In 19 other tests, it performs about the same. In all instances where it wins, Clang also wins, so the win is not because of this compiler. In 2 out of the 3 tests where it looses, it also trails Clang. It's a patchset to clang, which it fails to improve.We did want to point to our guide on installing Linux kernel 4.
Even if you need to use Ubuntu The AMD Ryzen 7 is an extremely interesting part. It can be overclocked with little effort. It also has a much lower TDP at 65W. We expect most X users will opt for a X motherboard. We recommend using Ryzen only with Linux kernels 4. Here is the guide to stop the crashes in CentOS 7 by upgrading the kernel to 4.
We are using gcc due to its ubiquity as a default compiler. One can see details of each benchmark here. The item to remember here is that any benchmark we are publishing has had at least 10, profiling runs on a multitude of different architectures to ensure we get consistent results before we add it to our repertoire. Due to the desktop nature of Ryzen chips, we are going to present our linux kernel 4. This is one of the most requested benchmarks for STH over the past few years.Astral sorcery growing crystals
The task was simple, we have a standard configuration file, the Linux 4. We are expressing results in terms of complies per hour to make the results easier to read. We wanted to point out that there are a few differences between our Ryzen 7 X results we published on launch day and the additional results here. Namely, we are using a different kernel that has many of the necessary patches required to make everything run smoothly.Taos mesa brewery
There are a few ways to look at this graph. If you have a bunch of AWS c4 instances crunching numbers, the payback, including electricity, will be around two months with the AMD Ryzen 7 X machines instead. We have been using c-ray for our performance testing for years now.
It is a ray tracing benchmark that is extremely popular to show differences in processors under multi-threaded workloads. There are two ways to view this graph. First, the AMD Ryzen 7 systems do extremely well in this type of workload.
We started using the program during our early days with Windows testing. It is now part of Linux-Bench. If you look near the bottom of that chart, you will find the 4 core Intel generations that also have ECC enabled and no 10GbE. Performance is not even close. Sysbench is another one of those widely used Linux benchmarks.
At this point, the chart is self-explanatory. It is even besting the higher clock speed Intel chips.
OpenSSL is widely used to secure communications between servers. We first look at our sign tests:. One of our longest running tests is the venerable UnixBench 5. They are certainly aging, however, we constantly get requests for them, and many angry notes when we leave them out. For example on our original AMD Ryzen 7 X review where UnixBench was crashing due to the kernel version we were using we left the results out and received many e-mails asking about them.
