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.
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.
