Thank god for AMD confirming that the PS4 already has hUMA.

(The AMD TrueAudio technology comes from the GCN 1.1 architecture which supports flat memory addressing to support the sharing of pointers and maintaining consistency of the whole die.)

PS4 makes game noises when user plays games

Pretty much sums it up. There are a few twists just how it is done. XBox One has a real Audio DSP, PS4 not, it simply uses a Jaguar core+audio en/de-coders - or gpgpu. PC uses DSP+DMA controllers, XBox One likely uses a DME (=DMA controller), PS4 probably uses a cache-controller (of the core assigned to audio). If PS4 wants the same cool sound the PC/XBox One makes, it has to use maybe 10-320% of a jaugar core (or use 5% gpgpu time). Note XBox One also needs a little cpu core, since doing some game logic never escapes the cpu. Unified memory always wins, so PC not good at this time. Any relevancy for "winning the console war": NIL.

So pretty much what Cerny stated about using the GPU for Audio effects. Only now we understand the hardware behind the statement.

@Bold What are you even talking about ? They both have audio DSPs and real ones to boot. It's just that we don't know if the X1 also features the same thing too.
