10-Way Radeon/AMDGPU Benchmarks On Linux 4.8 + Mesa 12.1 Git

Continuing off from the fresh open-source AMDGPU test data from yesterday's AMDGPU-PRO vs. open-source Polaris + Fiji comparison, here are more AMD graphics cards tested from the Linux 4.8 development code paired with Mesa 12.1 Git.

The GPUs tested for this weekend benchmarking fun were the Radeon HD 6870. HD 7950. R7 260X. R9 270X, R9 285, R7 370, R9 Fury, RX 460, RX 470, and RX 480. All tests happened from Mesa 12.1-dev via the Padoka PPA this week on Ubuntu 16.04 LTS paired with the Linux 4.8 kernel from 18 August. Note that with Mesa Git on pre-GCN GPUs there is only OpenGL 4.1 support for the Radeon HD 5800/6900 series while all other cards such as the HD 6870 are still currently bound to OpenGL 3.3 due to lacking FP64 emulation support.

Aside from the R9 290 having been in a regressed state, during this testing it was discovered my Radeon R7 260X is performing like garbage now too on this latest open-source driver code. After testing all of the other cards and seeing how poorly the R7 260X, I re-tested the R7 260X again and it remained to be in a troubled state -- yet no messages in dmesg or other easy explanation for the regression but perhaps is related to the cause of the R9 290 and friends dropping.

See more of these OpenGL test results via this OpenBenchmarking.org file. To see how your own Linux graphics performance compares, simply install the Phoronix Test Suite and run phoronix-test-suite benchmark 1608213-PTS-OPENAMD303.
