Benchmarking Amazon EC2 Instances vs. Various Intel/AMD CPUs

Given the recent performance changes following the Spectre/Meltdown CPU vulnerability mitigation and having just wrapped up some fresh CPU bare metal benchmarks as part of that testing as well as the recent AMD Raven Ridge launch, I've carried out a fresh round this week of benchmarks on various Amazon EC2 on-demand instance types compared to a number of bare metal Intel and AMD processors in looking at how the compute performance compares.

RadeonSI Now Offers NIR Shader Cache Support

Earlier this month Valve Linux GPU driver developer Timothy Arceri landed NIR shader caching support within the Gallium3D Mesa state tracker as an alternative to the existing TGSI IR caching support. Arceri has now worked through implementing this NIR cache support for the RadeonSI driver.

Ryzen 3 2200G Video Memory Size Testing On Linux

One of the discussion items in the forums this week was about the video memory allowance for the Vega graphics on Raven Ridge APUs as well as efficiences or inefficiencies around the TTM memory manager as used by the AMDGPU kernel driver. Here are some vRAM size tests with the Ryzen 3 2200G.

AMD's Raven Ridge Botchy Linux Support Appears Worse With Some Motherboards/BIOS

With my launch testing of the Raven Ridge desktop APUs with the Ryzen 5 2400G and Ryzen 3 2200G there were some stability issues to report and some hangs within games and mode-setting issues. It appears those issues are exacerbated with some motherboards: the past few days with two different AMD B350 motherboards have been a real pain getting the current AMDGPU driver stack working -- and even Linux 4.17 AMDGPU WIP code -- on either of these Raven Ridge APUs.

Wine-Staging Will No Longer Be Putting Out New Releases

Wine-Staging as many of you have known it for the past four years is unfortunately no more. We'll see if other reliable folks step up to maintain this experimental version of Wine but the original developers have sadly stepped away.

Initial Intel Icelake Support Lands In Mesa OpenGL Driver, Vulkan Support Started

A few days back I reported on Intel Icelake patches for the i965 Mesa driver in bringing up the OpenGL support now that several kernel patch series have been published for enabling these "Gen 11" graphics within the Direct Rendering Manager driver. This Icelake support has been quick to materialize even with Cannonlake hardware not yet being available.

AMD Raven Ridge Graphics On Linux vs. Lower-End NVIDIA / AMD GPUs

This week we have delivered the first Linux benchmarks of the OpenGL/Vulkan graphics capabilities of AMD's new Raven Ridge desktop APUs with the Vega 8 on the Ryzen 3 2200G an the Vega 11 on Ryzen 5 2400G. Those tests have included comparisons to the integrated graphics capabilities of Intel processors as well as older AMD Kaveri APUs. For those interested in seeing how the Raven Ridge Vega graphics compare to lower-end Radeon and GeForce discrete graphics cards, here are those first Linux benchmarks.
