The difference in investment is really exciting and kind of funny to think about. Last gen the hardware wasn't that great and there wasn't so much custom hardware. This gen, both GPUs were largely better than most of what AMD had announced so far and on top of that, there's a huge amount of custom hardware (audio chips, I/O, and maybe other stuff we haven't heard of yet). And that custom hardware is dedicated to processes that the main CPU on the PS4 couldn't even do. MS and Sony both talked about how they helped AMD develop RDNA 2, which I am not sure if they were quite as involved last gen. |
Microsoft and Sony's extent in assisting AMD develop RDNA 2 pretty much stops at the "suggestion" level, AMD has allot of I.P and trade secrets locked up in Radeon graphics that they need to protect, although they are more open about things than they used to be... nVidia and AMD have the technological lead in graphics processing that is unmatched by any other company on the planet, including mobile efforts, that isn't an advantage they want to loose.
RDNA for all intents and purposes is based on Graphics Core Next, even uses the same instruction set and predates even the 8th gen consoles, RDNA2 builds upon that foundation... RDNA2 would have probably started development a decade ago, long before Microsoft and Sony were starting to think about 9th gen hardware at a low-level.
It was like with the Playstation 4, Sony made a semi-custom chip leveraging AMD's technologies, Sony asked AMD to bolster the ACE counts for their chip, which AMD later adopted into later variants of Graphics Core Next which gave AMD the edge in Asynchronous Compute.
The Audio is definitely interesting, need more details on that technology, it might just be an extension of TrueAudio Next, which is an upgraded ASIC that was found in the Playstation 4... But it's a return to 3D positional Audio that the Original Xbox had thanks to the Soundstorm chip in the OG Xbox and what Aureal A3D impressed the world with all those years ago before Creative and Microsoft fucked things up.
I/O I am going to assume that Asmedia played a role with there, AMD likes to outsource that kind of work to them... For good reason.
Either way, this is the most technologically interesting console generation since the 6th gen in my opinion.
