Kann der x264 Encoder schon AVX2 der Haswell CPU nutzen?

[Gast]

Und falls nein, bis wann soll das implementiert werden?


Weiß das jemand?

Performance gain in x264, per clock (roughly):

Ivy Bridge -> Haswell: 17% (~5 of which is from AVX2)
Sandy Bridge -> Haswell: 28%
Nehalem -> Haswell: 39%


[/QUOTE]Haswell is not really very different from Nehalem/Sandy Bridge/Ivy Bridge architecture-wise, besides of course the larger datapaths and wider SIMD.

There'll probably be a lot of room to improve things in 10-bit, but 8-bit is probably close to done.[/QUOTE]
