16-Way GPU Comparison With NVIDIA GPUs Going Back To Kepler

Last week I provided a fresh look at the NVIDIA GeForce vs. AMD Radeon Linux gaming performance using the latest drivers at the start of 2018. That testing included the latest NVIDIA and AMD GPUs, but for those curious how these numbers compare for older NVIDIA GPUs, here's a look with the Kepler and Maxwell graphics cards added to the comparison.

Intel's Mesa Driver Is A Step Closer To ARB_gl_spirv Support

Igalia has sent out the fourth version of their patches for wiring in ARB_gl_spirv support into the Mesa OpenGL driver. This extension is the last main blocker from Intel having OpenGL 4.6 support and allows for SPIR-V ingestion support for better interoperability between OpenGL and Vulkan.

ADATA XPG SX6000: Benchmarking A ~$50 USD 128GB NVMe SSD On Linux

While solid-state drives have generally been quite reliable in recent years and even with all the benchmarking I put them through have had less than a handful fail out of dozens, whenever there's a bargain on NVMe SSDs, it's hard to resist. The speed of NVMe SSDs has generally been great and while it's not a key focus on Phoronix (and thus generally not receiving review samples of them), I upgrade some of the server room test systems when finding a deal. The latest is trying an ADATA XPG SX6000 NVMe SSD I managed to get for $49.99 USD.

Benchmarking Ubuntu's Low-Latency Kernel & Liquorix Post-Meltdown

A new Phoronix Premium member was hypothesizing in the forums whether Ubuntu's low-latency kernel would be performing better in the wake of the Kernel Page Table Isolation (KPTI) support in the kernel for fending off the Meltdown CPU vulnerability. With always aiming to deliver on test requests by premium members, I ran some benchmarks of the Ubuntu low-latency vs. generic kernels and I also tossed in the Liquorix kernel for benchmarking too.

Some Of What's Coming For Wayland's Weston 4.0 Compositor

Earlier this week ongoing Wayland/Weston release manager Bryce Harrington at Samsung laid out plans for Wayland 1.15 and Weston 4.0. There's been some push-back on the proposed dates to try to allow some more work to land in these upcoming six month releases to Wayland/Weston, but long story short, these next releases will be here in the near future.

Tweaking Ubuntu 17.10 To Try To Run Like Clear Linux

Even with the overhead of having both KPTI and Retpoline kernel support in place, our recent Linux distribution benchmarks have shown Intel's Clear Linux generally outperforming the more popular distributions. But if applying some basic performance tweaks, can Ubuntu 17.10 perform like Clear Linux? Here are some benchmarks looking at a few factors.

GCC 8.0 vs. LLVM Clang 6.0 On AMD EPYC

At the beginning of January I posted some early LLVM Clang 6.0 benchmarks on AMD EPYC while in this article is comparing the tentative Clang 6.0 performance to that of the in-development GCC 8.0. Both compilers are now into their feature freeze and this testing looked at the performance of generated binaries both for generic x86_64 as well as being tuned for AMD's Zen "znver1" microarchitecture.

Linux Graphics Trends Over The Past Five Years

Yesterday I posted some Linux hardware statistics going back to 2011 using data collected by the Phoronix Test Suite and OpenBenchmarking.org. Those yearly metrics hadn't contained any GPU/driver data, but here are those numbers.

Systemd 237 Will Have Support For WireGuard

The next release of systemd, v237, will introduce support for WireGuard. WireGuard as a reminder is the effort to provide a fast, modern and secure VPN tunnel that eventually plans to be part of the mainline Linux kernel.

Initial Intel Ice Lake PCH Support Posted

A few days back I wrote about open-source Intel developers posting their initial GPU driver patches for Icelake "Gen 11" graphics. That first code drop was just the tip of the iceberg unlike code drops for previous generations where they published the whole stack at once. But now the developers have already moved on to publishing more of the code.
