Intel Haswell Linux OpenGL Driver Catching Up To The Intel Windows Driver
Like Furmark, the synthetic triangle test of GpuTest showed the Windows driver still being quite a bit faster.
The Pixmark tests were relatively close to the Intel Windows driver.
While the OpenGL performance improved a lot this year for Intel Haswell and for some tests there's now close to a performance parity, the open-source Linux driver still lags behind on features. The Intel Windows driver boasts OpenGL 4.3 compliance for the Haswell HD Graphics while on the Linux side it's still stuck at OpenGL 3.3. At least in 2014, the OpenGL 4.0~4.2 support is coming along well and we'll hopefully see that in Mesa in the first half of 2015. The Intel OpenCL Linux support also finally matured this year with Beignet now providing modest OpenCL compute support via an open-source stack.
Stay tuned for many more Linux graphics benchmarks in 2015. If you appreciate the testing done please consider subscribing to Phoronix Premium or making a year-end PayPal contribution.
