They are x86 APUs with a very powerful GPU and high memory bandwidth. Something you can not buy on the open market to use it as a PC so far.

- easytiger 5y agoI think LTT had some boards they bought from China that are very similar to the ps5 mainboard. PCB even looks nearly identical with the ring configuration of the layout. https://linustechtips.com/topic/1383323-why-is-amd-selling-broken-playstations/ https://linustechtips.com/topic/1383323-why-is-amd-selling-b...
- MikusR 5y agoThose have the gpu disabled
- doikor 5y agoBut that is just the CPU. Basically the expensive part (the beefy integrated gpu) is not working and thus the still working parts (cpu, memory, io, etc) are being sold instead of being thrown into trash.
- easytiger 5y agoYea, I was just pointing it out.
- rbanffy 5y agoThat’s a good point. The 5 has about the same memory bandwidth of an M1 Max, which is something you’ll only find in 2-socket big Xeons (NUMA excepted), but the PS4 is on the same ballpark of a Threadripper Pro. Still, they are very much PCs with memory systems that are not available in general purpose boxes of the same price. I remember, however, some benchmarks on motherboards with console CPUs that were somewhat disappointing because the GDDR6 memory has high bandwidth at a higher latency cost that the internal caches couldn’t hide. Still, if you can tune your workload for it, it may be an interesting compute box.
