Intel Adds HEVC Encode API To VA-API

Intel previously committed an H.265 / HEVC video decoding API to the video acceleration VA-API interface. The Intel VA-API developers have now complemented that by adding a HEVC encode API to this open-source GPU-based video acceleration library.

Linux 3.19, 3.20/4.0 Doesn't Do Much For Intel HD 5500 Performance

Yesterday I ran some benchmarks from the new Core i3 Broadwell NUC to see how the latest Mesa Git affects the OpenGL performance for the Core i3 5010U chip with HD Graphics 5500. Today I'm complementing that testing to see if the latest Linux kernel Git makes any difference for this low-end, low-power Broadwell chip.

Intel ILO Gallium3D Driver Updated For Broadwell

While Intel's official Mesa DRI driver has supported "Gen8" Broadwell graphics for many months, today the support for these latest-generation HD/Iris Graphics processors landed within the unofficial ILO Gallium3D driver.

Intel Iris Graphics Performance On Linux 3.19 Shows Some Regressions

For any Intel Haswell Linux users with Iris Graphics thinking of switching to the Linux 3.19 kernel when it's released in what might just be a few hours, be forewarned as testing this weekend revealed there looks to be an OpenGL performance regression attributed to this new kernel.

A Five Year Old NVIDIA GPU Can Still Beat Broadwell HD Graphics 5500

I'm still benchmarking many laptops around here with the current build of Ubuntu 15.04 as part of my large forthcoming laptop comparison pitted against the new Lenovo ThinkPad X1 Carbon with Intel Broadwell processor. For another perspective on the Broadwell HD Graphics 5500 OpenGL performance, here's a laptop comparison against an old ThinkPad with discrete NVIDIA graphics.

Broadwell Linux Ultrabook Running MUCH Cooler Than Haswell

Aside from the performance benefits of Broadwell, particularly in having greater graphics capabilities, laptops and ultrabook designs are much more power efficient than former Haswell products. Here's some quick tests I did today comparing the Broadwell-based Core i7 ThinkPad X1 Carbon to my former Haswell-based Core i7 ASUS Zenbook ultrabook.

Test Driving The New Intel Haswell Linux Performance Patch

Hitting the Intel DRM tree this week was the much anticipated Haswell performance patch that was previously talked up by LunarG for benefiting Valve's OpenGL games on Linux. I've ran a few quick benchmarks today of the new Linux kernel code.

The Intel Haswell OpenGL Performance Boosting Patch Is Published

Back in November I wrote about a Major Performance Breakthrough Discovered For Intel's Mesa Driver due to testing done by LunarG and uncovered with the help of Intel. That performance-boosting patch has been queued up for drm-intel-next thus meaning it will be present with the next major kernel cycle -- the Linux 3.20 kernel.
