On Friday, Beamr Imaging claims to have achieved the world's first real-time 8K HEVC encoding by using a single EPYC 7742, AMD's flagship server CPU based on its new Rome architecture.
A single 64-core EPYC 7742, which features the 7nm process and the Zen 2 microarchitecture (the same type of cores found in Ryzen 3000), encoded 8K footage in real time at 79 frames per second with 10-bit color required for HDR.
It's a significant achievement for both hardware and software; the Epyc 7742 is the world's first 64-core x86 CPU to come in a standard general-purpose socket, and the Beamr encoding software is designed to use all 64 of those cores. Parallelization is a significant concern for CPUs with increasingly larger core counts, from consumer to server applications, so it's nice to see the 7742 used to the fullest.

The Epyc is for companies like Google and Netflix. I hear the GPU-based encoders have worse quality. You only need to encode it several times in good quality, once for each resolution, then you are serving it out thousands or millions of times.

I strongly doubt Google is going to use $7000 CPUs to encode videos at 60fps. Seems more likely they'll use stuff that'll give more fps per $$ and watt.
