Phoronix: Intel Broadwell On Linux Has Working OpenCL 1.2, VP8 Video Acceleration

In the past few days when begining to deliver a number of initial Linux tests from Intel's new Broadwell processors, a number of Phoronix readers have inquired about the OpenCL and VA-API support for the new hardware...

AMD has OpenCL 2.0 support and OpenCL 1.2 for AMD 2.0/1.2 certified CPUs/APUs and GPGPUs for Linux already.

No, AMD still has this, without even any image support:

Maybe there will be HEVC later, but MVC is at least there. What is the best Linux player for ssif right now?

[SystemCrasher]

Yet intel GPU is weak and too bad they mostly gave up on older units. So if you have older Intel-based device it means you're totally out of luck and hell yeah, it is very expensive and impractical to upgrade GPU on, say, notebook. That's where intel policy suxx. Though maybe they had too crapy GPU hardware before that point? On other hand its pity AMD lags behind when it comes to standard they've created years ago.

SMAP

Not related but thanks for the cpuinfo. I can see that it show SMAP support there. To the best of my knowledge no Haswell ever shipped with SMAP so this is a first. Here are the new flags compared to my Core i7 4770:

> 3dnowprefetch
> adx
> epb
> rdseed
> smap

I wonder if the RTM and HLE are broken as on Haswell or they work as they should. I vaguely remember reading somewhere that the first mobile Broadwells will ship with the same defective TSX implementation as Haswell.

Thanks to or because of VP9 VP8 has and will never really take off.
So I don't care about VP8 acceleration, only VP9 matters, youtube is all VP9 afaik.

[2ezhi]

Any tests how fast vp8 encoding acceleration works?

[89c51]

AMD has OpenCL 2.0 support and OpenCL 1.2 for AMD 2.0/1.2 certified CPUs/APUs and GPGPUs for Linux already.

I doubt AMD is even close to Intel in term of features in the open driver.
