Intel Broadwell Iris Pro Graphics: Windows 10 vs. Linux

Lastly for this initial Intel graphics comparison for the day-old Windows 10 are some synthetic tests using GpuTest.

With many of the GpuTest cases, the Intel Windows 10 driver remained faster than the latest Intel Linux driver code.

In the Pixmark tests, the Linux driver on Fedora 22 came out ahead.

There's also some tests that run fine under the Intel Windows 10 driver but not the Intel Linux driver at this time. As a reminder, the Intel Windows driver exposes OpenGL 4.3 and OpenCL 2.0 support while at the moment the Intel driver exposes OpenGL 3.3 (but 4.0~4.1 in the coming days) and OpenCL 1.2.

These results were interesting for our first Windows 10 benchmarks, albeit the Intel Linux driver ended up being a little bit slower than the Intel closed-source Windows driver in many of these OpenGL tests.

If you appreciate the Linux hardware reviews and unique Linux tests like these that I do at Phoronix, please consider subscribing to Phoronix Premium to allow such testing to continue in the future. Consider a PayPal tip or Bitcoin if wishing for more Windows vs. Linux benchmarks and to invest in adding more Windows-compatible tests, etc, as outlined earlier.
