Ampere Altra vs. Amazon Graviton2 Linux Performance Benchmarks

Last month we provided benchmarks of Ampere Altra against Intel Xeon and AMD EPYC with the Q80-33 CPUs in a 2P / 160 core configuration. From that article, reader questions were raised about how this high performance ARM server chip compares to Amazon's Graviton2 processors, so in this article today are such benchmarks. The Graviton2 via an AWS m6g.metal instance with 64 cores was compared to the Ampere Altra Q80-33 in its 2P 160 core configuration, 1P 80 core configuration, and then a 64 core configuration to match the Graviton2 by disabling the excess cores.

Ampere Altra Performance Shows It Can Compete With - Or Even Outperform - AMD EPYC & Intel Xeon

While the talk in recent weeks has been about the performance of Apple's M1 ARM chip and then rumors there might be a 32 core chip in the pipe, there is already something much stronger: Ampere Altra has begun shipping and its flagship 80-core SoC with up to two sockets per server can easily take on the AMD EPYC 7742 "Rome" and Intel Xeon Platinum 8280 "Cascade Lake" performance across a variety of workloads. Here is our initial look at the Ampere Altra performance on Linux in our independent performance benchmarks.

The Spectre Mitigation Performance Impact On AMD Ryzen 5000 "Zen 3" Processors

For those wondering what the current cost is to the default Spectre mitigation protections on the new AMD Ryzen 5000 series "Zen 3" processors, here are a set of performance tests looking at that overhead with the still relevant mitigations applied by default and then if forcing them off. The Zen 3 mitigation overhead was compared then to similar AMD Zen 2 and Zen+ processors.

AMD Ryzen 7 5800X Linux Performance

Over the past week we have looked at the AMD Ryzen 9 5900X/5950X Linux performance as well as that of the lower-end -- but still very powerful -- Ryzen 5 5600X. Today we are striking in the middle in looking at the last Zen 3 CPU model for the moment: the Ryzen 7 5800X. The AMD Ryzen 7 5800X is a $449 USD processor that is packing eight cores / sixteen threads, a 3.8GHz base clock. 4.7GHz boost clock, 32MB L3 cache, and has a 105 Watt TDP.

AMD Ryzen 5 5600X Linux Performance

Following yesterday's launch-day AMD Ryzen 9 5900X/5950X benchmarks that showed the utter domination of Zen 3 carrying over just fine in the Linux realm, today we are looking at the performance of the Ryzen 5 5600X on Ubuntu against other Intel/AMD processors. The Ryzen 5 5600X is AMD's new $299 USD part that offers six cores / twelve threads and incredible uplift still over Zen 2 / Zen+ processors while outperforming Intel's Comet Lake competition.

AMD Ryzen 9 5900X + Ryzen 9 5950X Dominate On Linux

The AMD Ryzen 9 5900X and Ryzen 9 5950X are hands-down incredible winners. While processor company marketing claims are sometimes dubious and not necessarily relevant to Linux users and their open-source workloads/software, after testing the Ryzen 9 5900X and 5950X the past several weeks the performance has been incredibly compelling with significant single and multi-threaded performance uplift over Zen 2 and easily thrashing Intel's current desktop offerings with over 200 benchmarks conducted for launch-day.

Further Exploring The Intel Tiger Lake Core i7-1165G7 Performance On Ubuntu Linux

Last week I published initial benchmarks of the Intel Core i7 1165G7 "Tiger Lake" performance on Linux with the Dell XPS 13 9310 Developer Edition laptop. Of most surprise from those preliminary Linux figures were finding that for some single-threaded workloads the performance was actually worse than the previous generation Ice Lake. Since then I've been running more tests around the clock with some interesting discoveries to note today. It is possible to enhance the single-threaded performance so it's performing better than Ice Lake as would be expected, but comes with lowering the multi-threaded performance compared to the results shared last week.

Intel 11th Gen Core "Tiger Lake" Launches

Intel Tiger Lake will soon begin appearing in laptops with an upgraded CPU architecture, the all new Iris Xe (Gen12) graphics, new AI capabilities, Thunderbolt 4, PCI Express 4.0, WiFi 6, and other new functionality. The Gen12 graphics have me most excited but there should be healthy improvements as well on the CPU side and not to mention improved connectivity.

Intel Celeron G5900 + Pentium Gold G6400 Benchmarks - Low-Price Comet Lake CPUs

While we have looked a lot at how the Core i9 10900K performs at the top-end of Intel's Comet Lake line-up as well as with the likes of the i5-10600K and i3-10100, here is our first look at the very bottom of the stack with the new Celeron and Pentium processors. Benchmarked today are the Celeron G5900 as a ~$40 processor and the Pentium Gold G6400 that retails for around $60 and compared against other low-end Intel and AMD processors as well as older Intel Core i3 CPUs.

The Linux Performance For AMD Rome vs. Intel Cascade Lake One Year After Launch

With the Intel 2nd Gen Xeon Scalable (Cascade Lake) processors having turned a year old in April and next month marking one year since the launch of the AMD EPYC 7002 (Rome) series, here are fresh benchmarks of the dual Xeon Platinum 8280 versus the AMD EPYC 7742 when testing the Linux software stack from early 2019 and then again using a bleeding-edge Linux software stack as of this month. This shows how the Linux software performance has evolved over the past year for both Intel and AMD on the server front as well as how the current top-end SKUs are competing right now.

AMD Ryzen 5 4500U Benchmarks - Previously Unimaginable Performance For Sub-$600 Laptops

A few weeks back I began delivering Ryzen 7 4700U Linux laptop benchmarks for this 8-core Zen 2 mobile CPU with Vega graphics. The results have been very good and the support is in good shape with the latest Linux kernel, but many have been wondering about the Ryzen 5 4500U. The Ryzen 5 4500U is beginning to appear in several $500~600 USD laptops and offers six cores. Here are benchmarks and initial impressions with the Lenovo Flex 5 that features a 14-inch 1080p display, 16GB dual channel memory, 256GB SSD, and the Ryzen 5 4500U all for just $599!
