An Early Look At The L1 Terminal Fault "L1TF" Performance Impact On Virtual Machines

Yesterday the latest speculative execution vulnerability was disclosed that was akin to Meltdown and is dubbed the L1 Terminal Fault, or "L1TF" for short. Here are some very early benchmarks of the performance impact of the L1TF mitigation on the Linux virtual machine performance when testing the various levels of mitigation as well as the unpatched system performance prior to this vulnerability coming to light.

A Look At The Windows 10 vs. Linux Performance On AMD Threadripper 2990WX

Complementing the extensive Linux benchmarks done earlier today of the AMD Threadripper 2990WX in our review (as well as on the Threadripper 2950X), in this article are our first Windows 10 vs. Linux benchmarks of this 32-core / 64-thread $1799 USD processor. Tests were done from Microsoft Windows 10 against Clear Linux, Ubuntu 18.04, the Arch-based Antergos 18.7-Rolling, and openSUSE Tumbleweed.

AMD Threadripper 2990WX Linux Benchmarks: The 32-Core / 64-Thread Beast

Whether you are compiling a lot of code, rendering models with Blender, or running various scientific workloads with OpenMP or MPI, the AMD Threadripper 2990WX is capable of delivering immersive Linux performance with its 32-cores and 64 total threads. While coming in at $1800 USD, the AMD Threadripper 2990WX can deliver better performance than the more expensive Intel Core i9 7980XE. Beyond being mesmerized about the performance today with this high-end desktop/workstation processor with the many thread-happy Linux workloads we encounter daily, this 32-core Zen+ processor has us even more eager to see AMD's next-generation Zen2-based EPYC CPUs next year.

AMD Threadripper 2990WX Cooling Performance - Testing Five Heatsinks & Two Water Coolers

The 32-core / 64-thread AMD Threadripper 2990WX carries a 250 Watt TDP rating, thus the cooling performance is quite important especially if you don't want to hit any thermal throttling with this $1799 USD processor. Fortunately, the 2990WX doesn't require water cooling but actually can work quite well with high-end air heatsinks too. For adding some perspective on the cooling requirements of the Threadripper 2990WX, here are benchmarks of five heatsinks and two all-in-one water cooling systems.

SoundWire For Linux Preps Support For Multiple Masters

Back in Linux 4.16 the SoundWire subsystem was added to the staging area as the MIPI standard for a low-power, two-wire sound bus that can support multiple audio streams and primarily utilized by small audio peripherals like IoT and mobile devices. With the next Linux kernel cycle, the SoundWire support is being improved upon.
