A Patch Is Being Worked On For Greater Kabylake Linux Performance With P-State

In our Intel Kabylake benchmarks we have shown how Intel's P-State CPU frequency scaling driver used by most Linux distributions can lead to much lower performance with their latest-generation processors compared to the ACPI CPUFreq scaling driver. Fortunately, action is taking place for improving the P-State performance with Kabylake.

OpenCL With An Intel Celeron: HD Graphics 610 / Kabylake GT1

Yesterday I published Linux benchmarks of the Celeron G3930, Intel's lowest-end Celeron CPU at the moment in the Kabylake family. This CPU goes for about $40 USD and you get a dual-core 2.9GHz processor with HD Graphics 610 (GT1). I had published a few OpenGL benchmarks in that review while for this article are some OpenCL compute numbers.

Expanded Turbo Boost Max 3.0 Support Is Being Worked On For Linux

With the forthcoming Linux 4.10 kernel there is finally support for Turbo Boost Max 3.0 as featured in some newer Intel CPUs. But, unfortunately, the code in Linux 4.10 doesn't work for all TBM3-capable systems out there, but a new kernel patch is being worked on for Linux 4.11 or later to make it work with more hardware.

Intel's Mesa Driver Set To Flip On OpenGL 4.5 For Haswell

It was just two weeks ago that Intel's Mesa driver finally crossed the threshold with Haswell for supporting OpenGL 4.0 and then last week OpenGL 4.2 was crossed for this older generation of Intel graphics hardware. Now, it looks like OpenGL 4.5 will be enabled for Haswell with the i965 Mesa driver.

Fresh Tests Of Intel Beignet OpenCL

When firing up Intel's Beignet OpenCL implementation on Clear Linux this weekend, I was surprised to see it was happily chugging along with many of our different CL benchmarks.

A Look At Where The P-State Linux Driver Does Bad Against CPUFreq, Clear Linux Tests

I'm still running more benchmarks in investigating the Core i5 7600K Linux performance and with even its graphics performance being slower than Skylake. I fired up Clear Linux on this Kaby Lake system this weekend and it's indeed faster than Ubuntu, though there still is some sort of fundamental issue at play with these new CPUs on Linux. But what is clear is that there are cases where the P-State CPU frequency scaling driver does perform very poorly over the mature, generic CPUFreq scaling driver.

It's Now Possible To Disable & Strip Down Intel's ME Blob

Many free software advocates have been concerned by Intel's binary-only Management Engine (ME) built into the motherboards on newer generations of Intel motherboards. The good news is there is now a working, third-party approach for disabling the ME and reducing the risk of its binary blobs.
