[x265] Recent Frames/second benchmarks per platform and per clip?

[Tom Vaughan]

Hi Mario,
It's easy for anyone to create a script to run a batch of performance tests.
With x265's csv log file feature, it's easy to review and chart your
results.  We can share example scripts if that helps anyone.

In addition to hand-tuned assembly code optimization for specific processor
instruction sets (SSE, AVX, AVX2), the team is refactoring code to improve
data movement and multithreading.  In genera the work we are doing to
improve performance will be very positive for people running the latest
hardware architectures, but it should not be negative for people running on
older platforms.

Tom

Hi Raul.

I am curious about the development of speed and efficiency too. But their
use for me is rather marginal, without any AVX capable CPU.

Especially recently, there was a lot of speed optimization mainly for AVX2.
Way beyond AMD Phenom-II. I can only hope that it doesn't get slower for
me...
