Thanks, Tom.
Yes, I already did batch testing, even just on a small video (QCIF
foreman); one with larger dimensions would be more accurate, but running
it 3 times each (to avoid mistakes by random slowdown effects due to
surprising activities, you know, it is Windows...) in the slowest presets
will take several hours per 10 seconds, so my hardware is not suitable
anymore. Nevertheless, I will stay curious, and I trust your efforts.
I already published a PDF with a few graphs here in this mailing list, I
may do that again soonish with additional results of more recent builds.

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...

Hi Raul,
Yes, you can ask those kinds of questions on this list.
We run a wide range of regression tests and performance tests weekly,
but for a number of reasons we don’t publish this test data publicly.
If there is a specific project that I can help you with, please
contact me directly.
Thanks,
Tom

clip?
Hi All,
Are there any recent reports of x265 encoding runs of known clips that
show the Frames/second and Y PSNR achieved in a certain platform for a
range of bitrates with certain encoding parameters?
I am looking for something like:
BQTerrace 1080p60, IDR refresh of 120, Delay of 1 second, preset
'faster'
15.3 Frames/second Y PSNR 33.23 dB for 3Mbps on Ivy Bridge i7 4C/8T
2.3 GHz (I just generated that today using x265 code from Sep 23,
2014).
Thanks for any leads. BTW, is this the correct x265 list to use for
these questions?
RAUL
