Microsoft claims that only Xbox boasts full support for AMD's RDNA 2 feature set

Will this place Sony's PlayStation 5 at a disadvantage?



Read more about Xbox Series X/S supporting AMD's full RDNA 2 feature set.

Why do people take their word for it? How would they know what Sony is doing? If they know for a fact it begs the question of how they came across this information.

Well I'm hearing different at least when it comes to infinity cache, but i'd expect Sony and MS to have similar rnda2 features while also being custom in some manner.

I don't think it will matter any way, even if true.

People who game on console are not like PC gamers. They don't buy a console based on performance they buy them based on the games that will be on them. The XB1X was superior to the PS4 Pro, yet the PS4 outsold the Xbox.

Bottom line is these games being made need to run on both so no one will care.

I mean yeah, it's bragging rights for Microsoft, but that won't matter squat.

My only point I was making Alien was just simply why people are been reporting this information. Why would you believe what one company says about another company they compete with? Makes no sense.

Maybe they include the turbo boost feature in their list of RDNA2 features, which Sony isn't using and instead aims to lock the frequency.

 

[grec]

Well ofc many of the features AMD revealed for RDNA are essentially just implementations of Microsoft specifications, including DXR, DirectStorage, and DirectML. Though ofc that's not to say Sony doesn't have viable alternative features, just that it won't use exactly the same IP or necessarily exhibit the same behaviour as that in the Xbox/PC hardware, could be as little difference as an instruction set change to accommodate a different API though I guess.

But the Xbox clocks are locked and the CPU only changes to a higher locked clock when the dev chooses?

My only guess is SAM is disabled on PS5 but that's kind of a moot feature loss since the entire system is custom anyway it's a better solution than just the PC version of SAM, at least at this moment

 

[grec]

SAM doesn't make any sense on an APU as everything is via one memory pool anyway, nothing to be transferred between GPU and CPU memory when they're already the same thing. As you say it's not clock speeds either, my guess has to be on it being (a) Direct API feature(s).

SAM isn't a console thing, the consoles use a combined memory pool which developers can use however they wish. With the CPU and GPU lacking separate memory pools, SAM has no reason to exist on a console system.

Exactly why I stated that. Only thing it wouldn't have is that and unless MS wanted to use it since they have different memory pools which would be why they are saying this nonsense.
