On my i7-2600k, encoding a Blu-ray takes about 10-12 hours for H.265 or 18-20 for VP9 with handbrake's default 1080p settings for each.
So yea, quite a bit slower, at least on my old hardware.
I still go with VP9, though. I don't buy that many movies, and leaving it running in the background doesn't seem to make a big impact on gaming.
- voltagex_ 9y agoI jumped from your chip to a 6 core Broadwell-E and it seems to give me about 15% more performance out of x264 encoding and 5% from x265. I see the same jump from C4 to C5 Amazon machines. I'd love to chat about encoding with you at some point.
- nfriedly 9y agoYikes! Is that 5-15% normalized to per-core performance, or does it really get almost 0 benefit from having 50% more cores? That difference from C4 to C5 makes more sense given that they each have the same number of cores available and it was a smaller generational gap.

- nfriedly 9y agoI should also mention that my BIOS has a performance setting that can be "Energy Saving", "Normal", or "High Performance", and I keep mine on "Energy Saving". Kicking it up a notch or two could undoubtedly boost the performance a bit, and a manual overclock should go even further. (My chip is stable at 4.7Ghz, but it consumes way too much power to leave it there all the time - the computer idles at ~70 watts on "Energy Saver" mode!)
