Intel Quicksyc memory bandwidth scaling? - sinholueiro - 2024-05-11
Hello all. I am planning in change my home server. I have an i5 8400 and I will change it for an i5 14600K. Do you know if Quicksync benefits for having more memory bandwidth? Because I can pair the i5 with DDR4 or DDR5. DDR4 is cheaper, but I could think of getting DDR5 if performance is better. Have anyone tested this? Thanks!

Quicksync, AFAIK, does not benefit from VRAM size nor bandwidth for transcoding performance. TONE MAPPING is a different story. It benefits greatly from more VRAM.

It makes sense, isn't tonemapping done in GPU cores? So more bandwidth is more performance. I guess I will keep my DDR4, then. Thanks!

Tone mapping uses openCL, so yes GPU cores.
