Open-Source Nouveau Linux 4.10 + NvBoost vs. NVIDIA Proprietary Linux Driver Performance

Earlier this week I posted some benchmarks showing the open-source NVIDIA (Nouveau) driver performance on Linux 4.10 with the new NvBoost capability for finally being able to hit the "boost" clock frequencies with Kepler graphics cards when using this reverse-engineered driver. While the manual re-clocking and enabling NvBoost is able to increase the Nouveau driver's performance, how do these results compare to using the closed-source NVIDIA Linux driver? These benchmarks answer that question.

AMDGPU-PRO vs. RadeonSI/RADV & NVIDIA's Linux Drivers To End 2016

Last week I published a 31-way Linux graphics card comparison with an assortment of both NVIDIA GeForce and Radeon graphics cards using the latest Linux drivers. I also published a variety of Vulkan benchmarks. In those tests the open-source Radeon driver stack was used given that's what AMD is endorsing these days for Linux gamers with AMDGPU-PRO not even working on all modern Linux distributions. But for those curious how AMDGPU-PRO compares to those big result data-sets, here are those -PRO results to share today.

AMDGPU-PRO 16.50 Rolls Out With GCN 1.0 Support, FreeSync

The embargo has just expired on the Radeon Software Crimson ReLive Edition release, which had leaked out a few days ago elsewhere. While Crimson ReLive Edition is a big update for AMD Windows users, on the Linux side there's less to talk about but it's still a rather big release. I've been testing the AMDGPU-PRO 16.50 release the past two weeks and overall it's a sizable update for those using this hybrid AMD Linux driver.

Intel Iris Pro OpenGL vs. Vulkan Benchmarks With Linux 4.9, Mesa 13.1-dev

It's been a while since publishing any fresh Intel Core i7 5775C benchmarks, the socketed Broadwell CPU with Iris Pro 6200 graphics, since normally it's busy in the daily benchmarking churn of the server room for Phoronix Test Suite / OpenBenchmarking.org / LinuxBenchmarking.com efforts. But with having been doing some maintenance on that system this week and loading a clean install of Ubuntu 16.10, I did some fresh benchmarks of the Iris Pro 6200 graphics using Mesa 13.1-dev and Linux 4.9, including a look at the OpenGL vs. Vulkan performance for the Iris Pro graphics.

Editorial: Using NVIDIA On Linux For The First Time In 10 Years

Anyone who read any number of my reviews from a few years ago, when I interned here at Phoronix, should know that I have been a fan of AMD and their open source efforts for a very long time. I remember the years of trying to get Catalyst to work under Arch or Fedora, usually only to have it blow up in my face. I remember the struggle holding back kernel and X server updates, hoping that none of those updates contained security fixes that were pertinent to me.

Radeon Vulkan Driver Added To Mesa, Fresh Radeon Vulkan vs. OpenGL Benchmarks + AMDGPU-PRO

Today the RADV Radeon Vulkan driver is landing in mainline Mesa and just hit the Git code minutes ago. Merging the RADV driver came up just over the past few weeks in time for next month's Mesa stable release while this community-based driver was developed over the summer by David Airlie and Bas Nieuwenhuizen. This "unofficial" Radeon Vulkan open-source driver is now becoming part of the Mesa code-base with it being able to support the few Vulkan Linux games but isn't yet a fully conformant driver. Here are fresh benchmarks of the RADV driver compared to the RadeonSI OpenGL driver and benchmarks compared to AMD's hybrid closed-source AMDGPU-PRO driver on several different graphics cards.
