Amlogic S905X5

S905X5 adds support for VVC a.k.a h266 hardware decoding. It uses the G310 gpu and unknown newer cpu core(s) than the A55 cores used in the S905X4.

Hm, armv9? Vapourware until 2024, big chance!

Sounds a good fit for an odroid c5 though…

Anybody knows if it supports AV1 or VVC hardware encoding? It would be nice to have it in a TVheadend server.

They are guessing 4xA510 cores which are comparable in performance to the A73’s. So we might expect a SOC with similar performance to the s922x (4xA73+2xA53). It might actually be a better SOC than the s928x.

But the DMIPS benchmark is single-threaded, is it common practice to multiply it by number of cores?
I think, on one core, it should have 10K DMIPS. This would be the speed of raspberry pi4@2GHz.

I’ve seen the s928x listed as 36K DMIPS. And the s922x with 43K DMIPS and A311D2 with 62K DMIPS.

Yeah adding up the cores can be misleading in terms of real-world performance since all these SOCs have different numbers of cores.
