With the MSI MEG X399 CREATION that we received as part of the launch package for the Threadripper 2950X and Threadripper 2990WX it includes the XPANDER-AERO that provides 4-way M.2 NVMe SSD slots on a PCI Express x16 card. The XPANDER-AERO is actively cooled and could be passed off as a small form factor graphics card upon a very cursory examination. With this card I've been running tests on four Samsung 970 EVO NVMe SSDs in RAID to offer stellar Linux I/O performance. Here are some initial benchmarks using Btrfs.

After resisting Gallium3D for the past decade with a preference on continuing to maintain their "i965" Mesa classic driver and all they've invested into its compiler stack and more, it seems times are changing as the open-source Intel team has been starting up development of a modern Gallium3D driver...
While yesterday were the benchmarks showing how Linux games struggle to scale past a few CPU cores/threads, in this article is a look at the scaling performance of various applications/workloads under Linux up to 64 threads using the AMD Threadripper 2990WX. Here's a look at how the Linux performance changes in a variety of applications from one to sixty-four threads with this new HEDT processor.

The good news is that the open-source AMD graphics team continues working on support for upcoming hardware, but the bad news is that it looks like their VCN video hardware might be a bit more locked down than it is now...
One of the frequent requests/comments stemming from the launch-day Windows 10 vs. Linux benchmarks on the new AMD Threadripper 2990WX were questions about whether this 32-core / 64-thread processor would do better with Windows Server given Microsoft's obvious tuning of that Windows flavor to high core/thread counts... Well, here are some initial figures with Windows Server 2016 and a Windows Server 2019 preview.
ARM has made public an aggressive CPU forward-looking road-map and some performance expectations. ARM is hoping to deliver year-over-year performance improvements of more than 15% through 2020...
On Monday when the launch embargo expired on the Threadripper 2950X and Threadripper 2990WX I hadn't run any gaming benchmarks since, well, most games even on Windows can't scale out to 32 threads let alone 64 threads... Especially on Linux. It's far more practical getting these Threadripper 2 processors if you want to compile with 32 or 64 make jobs -- among many other common multi-threaded Linux workloads -- versus using this $899 or $1799 processor for a Linux gaming system. But if you are curious how Linux games scale with the Threadripper 2950X, here are some benchmark results when testing both AMD Radeon and NVIDIA GeForce graphics.
Last month I wrote about lazy TLB mode improvements on the way to the mainline kernel and this week the changes were indeed merged for the in-development Linux 4.19 kernel...
