Is SVT-HEVC faster then HandBrake?

SVT-AV1 is slow on a Threadripper, according to some benchmark I saw, around 30 FPS, and that's 1080p.

Oh wait, that benchmark for SVT-HEVC, was only 1080p. I need to know the 4k FPS. My CPU won't get the same speed as a Threadripper.

8k encoding using SVT-HEVC requires 64 GB of RAM.
