I don’t know if the TS-873A is really geared towards VMs. The Risen V1500 is still an embedded processor. The i3 in my TVS-672XT is faster and it’s an older processor. Only advantage the Ryzen has is it is 4 cores with 2 threads per core while the i3 is 4 cores and 1 thread per core.
But yes, VMs can utilize the GPU if you have one there. I just didn’t find that much use from it. Was hoping the QNAP AI Core would use it for things like QuMagie but no such luck. And aps like Plex don’t use it for hardware transcoding either.
