As has been known for a while now, AMD Ryzen Threadripper processors really show their true potential on Linux with often significant increases to the performance thanks to the kernel's better scalability compared to Microsoft Windows. While Microsoft has made some improvements in this area over the past year, with the AMD Ryzen Threadripper 3990X 64-core / 128-thread HEDT processor it really shines on Linux. In this article are benchmarks of Windows 10 Professional and Windows 10 Enterprise against Linux on the Threadripper 3990X when going from 16 cores to 128 threads for seeing how the three operating systems are scaling.

Here are some fresh numbers looking at the current performance of various AMD EPYC 7002 "Rome" processors up against Intel Xeon Cascade Lake processors when using an Ubuntu 20.04 LTS development snapshot and also upgrading to Linux 5.5 as the latest stable kernel. Beyond raw performance, power efficiency and performance-per-dollar for these different server CPUs are being compared as well for these sub-$5000 processors.

If you are looking for the absolute best single-socket workstation performance for Linux, there has already been the Threadripper 3970X that easily outperforms the likes of the Core i9 10980XE as Intel's top-end HEDT product, but now the Threadripper 3990X is shipping. The Threadripper 3990X is AMD's first 64-core / 128-thread desktop/workstation processor and will love your multi-threaded workloads from code compilation to content creation. As shown in our benchmarks, this single CPU is indeed faster than $20k worth of Intel Xeon Platinum CPUs.

This week our AMD Ryzen 9 3950X review sample finally arrived and so we've begun putting it through the paces of many different benchmarks. The first of these Linux tests with the Ryzen 9 3950X is looking at the performance up against the Ryzen 9 3900X and Intel Core i9 9900KS in 149 different tests.

Announced last month was the Athlon 3000G as a ~$49 processor based on Zen and featuring two cores / four threads and Vega 3 graphics. This 35 Watt TDP processor has finally begun appearing at more Internet retailers in stock last week and I was able to pick up one of these budget CPUs for $55 USD. Here are benchmarks of the Athlon 3000G on Ubuntu Linux compared to other low-end and older processors.

Since the AMD EPYC 7002 "Rome" series launch in August we have continue to be captivated by the raw performance of AMD's Zen 2 server processors across many different workloads as covered now in countless articles. The performance-per-dollar / TCO is also extremely competitive against Intel's Xeon Scalable line-up, but how is the power efficiency of these 7nm EPYC processors? We waited to deliver those numbers until having a retail Rome board for carrying out those tests and now after that and then several weeks of benchmarking, here is an extensive exploration of the AMD EPYC 7002 series power efficiency as well as a look at the peak clock frequencies being achieved in various workloads to also provide some performance-per-clock metrics compared to Naples.

Complementing our launch-day Intel Core i9 10980XE and AMD Ryzen Threadripper 3960X/3970X Linux benchmarks, here is much more data now that we've had the additional time for carrying out more tests... For your viewing pleasure this US holiday week are more than 330 benchmarks carried out on both the Core i9 10980XE and Threadripper 3960X in the same configuration while running Ubuntu Linux.

After the embargo on the Intel Core i9 10980XE expired a few hours ago, now we are allowed to share the performance numbers on the new AMD Ryzen Threadripper 3960X and 3970X processors. These new Zen 2 HEDT CPUs pack a real performance punch, but do come in as more expensive than the i9-10980XE and there is one boot-stopping Linux bug to mention with a workaround... But besides that lone Linux support caveat, the Threadripper 3960X and Threadripper 3970X absolutely dominate in performance.

Intel today is rolling out the Core i9 10980XE as their new Cascade Lake X-Series processor that features 18 cores / 36 threads with a maximum turbo frequency of 4.6GHz and TBM 3.0 frequency of 4.8GHz. Following a last minute change, Intel moved up the embargo lift time of the Core i9 10980XE so here are the results we can share with you right now.

With the many Intel Ice Lake Linux benchmarks we began publishing over the past month since picking up a Dell XPS with Core i7-1065G7, there have been many benchmarks compared to the likes of the Core i7 Whiskey Lake and Kaby Lake processors. For those curious how the performance stacks up going further back, here are some Ubuntu 19.10 laptop benchmarks putting it up against the likes of Core i7 Haswell and Broadwell processors.

Intel is today making public the Jump Conditional Code (JCC) erratum. This is a bug involving the CPU's Decoded ICache where on Skylake and derived CPUs where unpredictable behavior could happen when jump instructions cross cache lines. Unfortunately addressing this error in software comes with a performance penalty but ultimately Intel engineers are working to offset that through a toolchain update. Here are the exclusive benchmarks out today of the JCC erratum performance impact as well as when trying to recover that performance through the updated GNU Assembler.

Today the Intel Core i9 9900KS is shipping at $513 USD for this specially-binned Coffeelake CPU that is capable of achieving a 5.0GHz all-core turbo frequency. The all-core 5.0GHz turbo is great, but it remains an eight-core / sixteen-thread 14nm processor going up against AMD's similarly priced Ryzen 9 3900X. Here are our initial benchmarks of the Core i9 9900KS compared to the Core i9 9900K and Ryzen 9 3900X.

Here are the latest numbers in our ongoing AMD EPYC 7002 "Rome" series benchmarking. This time around for some curiosity over the weekend is a look at the EPYC 7642 and EPYC 7742 up against the Xeon Platinum 8280 all in 2P configurations while running benchmarks publicly recommended by Intel in one of their whitepapers. Even going by Intel-recommended tests, the EPYC 7642/7742 deliver significantly better performance and cost savings over the comparable Xeon Platinum 8280.

Following this week's Intel Core i7-1065G7 Ice Lake Linux benchmarks there was some questions and speculations about the per-clock performance of this long-awaited Intel microarchitecture update. Here is some additional data shedding light on the clock frequencies under load and ultimately how the per-clock performance compares to the common Intel previous-generation mobile CPUs.

Recently I picked up a Dell XPS 7390 Core i7 Ice Lake laptop for finally testing this Intel 10nm+ processor under Linux. I have delivered some results so far like the Windows vs. Linux OpenGL/Vulkan performance and the Spectre impact with Ice Lake while this article is the first of several really drilling down on the CPU performance. In this article are benchmarks showing how the Core i7-1065G7 compares in raw performance and performance-per-Watt to the earlier Core i7-8565U (Whiskey Lake) and Core i7-8550U (Kabylake-R) processors.

Following the benchmarks earlier this month looking at PostgreSQL 12.0 on AMD EPYC Rome versus Intel Xeon Cascade Lake there was interest from Phoronix readers in wondering how well Rome is doing for other modern enterprise database workloads. One of those workloads that was recently added to the Phoronix Test Suite / OpenBenchmarking.org is Facebook's RocksDB, the company's embedded database that is forked from Google LevelDB. With RocksDB being designed to exploit many CPU cores and modern SSD storage, here are some benchmarks looking at how the Xeon Platinum 8280 stacks up against various new AMD EPYC 7002 series processors.

Last week I shared benchmark results of the AMD Ryzen 9 3900X vs. Intel Core i9 9900K in 400+ benchmarks in the largest comparison ever for these two competing ~$500 USD processors. If that wasn't enough, I repeated the hundreds of CPU/system benchmarks again but without any of the recent CPU security mitigations in place to see how the situation would have played out pre-2018.

Given the recent AMD "ABBA" Ryzen 3000 boost fix, the upcoming release of Ubuntu 19.10 powered by Linux 5.3, here is a fresh round of AMD Ryzen 9 3900X vs. Intel Core i9 9900K benchmarks in a side-by-side matchup . It's just not any comparison but our largest i9-9900K vs. 3900X comparison ever: 112 gaming benchmarks and 321 system/CPU benchmarks carried out for our most extensive look yet at how these ~$500 CPUs are competing in this fierce race.

Since the AMD EPYC 7002 series "Rome" launch at the beginning of August, it's been known how AMD's top-end (aside from the newly-announced EPYC 7H12) EPYC 7742 easily outperforms the Intel Xeon Platinum 8280 in most real-world benchmarks. The EPYC 7742 not only outperforms the Xeon Platinum 8280 in raw performance but also at a significantly lower cost and it gets even better with the EPYC 7642. We have been testing the EPYC 7642 48-core processors and even there the performance is generally ahead of a Xeon Platinum 8280 while being about half the cost of that flagship non-AP Intel Xeon Scalable Cascadelake processor.

Last week AMD's AGESA "ABBA" update began shipping with a fix to how the boost clock frequencies are handled in hopes of better achieving the rated boost frequencies for Ryzen 3000 series processors. I've been running some tests of an updated ASUS BIOS with this adjusted boost clock behavior to see how it performs under Linux with a Ryzen 9 3900X processor.

Last month we provided launch-day benchmarks of the AMD EPYC 7502 and 7742 under Linux in both 1P and 2P configurations for these exciting "Rome" Zen 2 server processors. For your viewing pleasure today is a fresh look at not only the EPYC 7502 and 7742 processors under the latest Linux 5.3 kernel but we've also expanded it to looking at the EPYC 7302 and EPYC 7402 processors as well with those processors recently being sent over by AMD. Under Ubuntu 19.04 with Linux 5.3, these four different AMD EPYC 7002 series SKUs were benchmarked along with some of the older AMD Naples processors and Intel Xeon Gold/Platinum processors for a fresh look at the Linux server performance.

Complementing our recent AMD Ryzen 5 3600X Linux benchmarking, with recently having out the Intel Core i7 3960X Sandy Bridge Extreme Edition, here are benchmarks showing that previous $999 USD six-core / twelve-thread processor compared to today's Ryzen 5 3600X (and previous-generation Ryzen 5 2600X) as well as the Core i7 8700K.

AMD Raven Ridge APUs were a rough launch particularly on Linux where even with the latest motherboard BIOS updates and Linux kernel I am still hitting occasional stability issues, so when the opportunity arose recently to try out the Ryzen 5 3400G as the successor in the Picasso family, I was interested. Fortunately, AMD Picasso APUs have proven to be in better shape on Linux so here is the initial round of performance tests for those interested in the AMD Linux performance on Ubuntu.

For those wondering how ARM and IBM POWER hardware stack up against AMD's new EPYC "Rome" processors and that of Intel's existing Xeon "Cascade Lake" processors, here is a round of tests from the POWER9 Talos II, Ampere eMAG, and Cavium ThunderX in looking at the cross-architecture Linux CPU performance currently in the server space.

Now that the new AMD Ryzen 3000 series are running great with the latest Linux distributions following prominent motherboard vendors issuing BIOS updates that correct the "RdRand" issue, we're moving on with looking at the performance of the rest of the Ryzen 3000 series line-up while having freshly re-tested the processors under Ubuntu 19.04. Up for exploration today is the AMD Ryzen 5 3600X, the six-core / 12-thread processor retailing for about $250 USD.

With last week's dramatic EPYC "Rome" launch where AMD has blown past Intel Xeon "Cascadelake" performance in a majority of server benchmarks, helping the successful launch of these Zen 2 server processors has been Intel's repeated delays of 10nm/Icelake CPUs and also the Spectre / Meltdown / Zombieload / Foreshadow mitigations. Out of curiosity, I've run some unmitigated benchmarks for the various relevant CPU speculative execution vulnerabilities on both the Intel Xeon Platinum 8280 Cascadelake and AMD EPYC 7742 Rome processors for seeing how the performance differs.

Now that you have read our AMD EPYC "Rome" 7002 series overview, here is a look at the initial performance benchmarks from our testing over the past few weeks. This testing focused on the new AMD EPYC 7502 and EPYC 7742 processors in both single (1P) and dual (2P) socket configurations using AMD's Daytona server reference platform. Tests were done on Ubuntu Linux and compared to previous AMD EPYC processors as well as Intel Xeon Scalable.

One month ago today we were talking about the AMD Ryzen 3000 series processor and new Radeon RX 5700 series graphics cards, all manufactured on TSMC's 7nm process. Today, for 7th August, the embargo has now lifted and we are talking about something arguably more exciting, or at least the ability to more profoundly impact an industry (data centers): AMD's EPYC 7002 series is ready and their line-up and ultimately the resulting performance is the most exciting and competitive we have seen ever out of AMD in the server space.

After weeks of anticipation, we can now share how the AMD Ryzen 7 3700X and Ryzen 9 3900X performance is under Linux. These first Zen 2 processors do indeed deliver a significant improvement over Zen/Zen+ processors and also battle Intel's latest 14nm CPUs but for Linux users there is one big, unfortunate issue right now.

A few weeks ago we received a POWER9 Raptor Blackbird for testing that features an IBM POWER9 4-core (16 thread) processor clocked at 3.80GHz. For those curious about the performance potential for low-end POWER9 parts compared to the more common high-core/thread count POWER processors we have benchmarked before like in the Talos II server, here are some initial tests of that petite POWER9 processor.
