Imagine my disappointment when I found out that Pi 4B won't do H.264 or even H.265 at 4Kp60 reliably, or at all. Not with stock Pi OS or Ubuntu, my transcoder setup, and the couple evenings of...

You might also want to try running 2 workers with 8 cores each. 5950X should still have almost enough L3 cache on each chiplet to run LL double check without hitting RAM. Assignments with larger FFT...

So it's coming out soon. $100 listed-price premium for lower base and boost clock, apparently no overclocking, and 64MiB more of L3 cache. Enough L3 for wavefront PRP for the foreseeable future, but...
