FSR4 on RDNA2 and 3 comparison

The difference id TFLOPs is not that big.

Besides, we have seen FSR4 run on a 6600XT well enough.
No I'm talking about TOPs not TF. TOPs helps to have more calculations AI based in less time. FSR4 is AI based in the end. XSX is not well equipped for such stuff and it could take more GPU mss especially working at lower resolution.

RDNA uses dp4a, do TOPs are run on the same shaders.
 
The main takeaway for me really is the Ryzen Ai MAX+ 395 miniPCs are going to thrive with FSR4 now. They were already a generation or two ahead of the handheld hardware out now, but with FSR4 that will keep them relevant for many years to come. Though all the handhelds also see the FSR4 gains, however they do not have the AI cores like those Ryzen 395 chips, so I have always expected they would age pretty well, for an all-in-one solution with no dGPU.
 
AMD/Sony, it's quite sure same model backporting that will be used for PS5Pro
And you can't say it slow as we don't know implications for int8 porting
The slow comment was sarcasm because some people are giving AMD shit for not releasing an unfinished project.

And? You need an optimal AI hardware to run AI upscaler, I doubt xsx can run a full fat FSR4 without any problems as for example ps5 pro because now "it works" on pc. Doesnt seems realistic to me. Maybe can do something more close to the DLSS on switch 2, obviously better but we have to see I guess how effective it's for resolution below 1080p compared FSR3.

the Series X should have no issue running this leaked FSR4 version, neither should it have any issue running XeSS. of course these versions of either aren't as good as the "full" quality versions that run on the intended dedicated hardware, but they are very competent already, even on low end hardware like the Steam Deck and other handheld systems

What part don't you understand that the Series X and the 6750XT have the same hardware.
Cu count and clocks speed vary, but they are not that far apart.
And even a 6600XT can run FSR4.

What part you don't understand about to have a discrete number of TOPs to run AI instructions for AI upscaler. I just expressed my doubt about the effectiveness and the cost on the XSX hardware.

Tell me the numbers you have. Go.
Why you ask me something you know? I don't remind the precise number but it's not remotely close to the ps5 pro. I guess you have to stay around this number to run an ai upscaler properly.

I know exactly how many TOPs each has. But I really want to know how much do you think they have, for you to make such a statement that the Series X is unable to run FSR4.

On RDNA2 Xess/FSR4 Int8 run on shaders - Xbox Series X support the same instructions as RDNA2 PC GPUs so it IS able to run those reconstruction techniques in games. Regular PS5 on the other hand is outdated in this aspect.

But I doubt we will see it in action.

I never said is not able to run FSR4. I doubt it can run it without compromises or excessive costs because there isn't the hardware TOPs number for obvious reasons.

Not even half of the ps5 pro if I'm not wrong.

The PS5 Pro has dedicated hardware. That is not the point.
The matter is that the Xbox Series X can do 48 TOPs total, using dp4a.
The 6750XT can to 53 TOPs, also using dp4a. It's not a huge difference.
And the 6600XT, can do 42.4 TOPs.

Of course that RDNA2 will never be able to run FSR4 as well as a chip that has support for ML.
But it can run it and it looks almost as good as FSR4 FP8. And even in the performance mode, it will look better than FSR3.1.

I want to remind to you even high AF is still expensive for console hardware but not on pc so I will be careful to say "because it works on pc it will work as the same on XSX".

the costs don't seem all that extreme on PC so far. especially considering that you can reduce render costs elsewhere because it allows a lower input resolution when using FSR4 to look better than FSR3 with a higher input resolution.

if FSR4 balanced mode looks better than FSR3 quality mode, the increased cost of FSR4 it's not really an issue.

Once again, ML runs mostly on L1 and L2.
And the Series X has more memory bandwidth that a 6750XT and much more than a 6600XT.
 
No, all those numbers are public.
And you still haven't disputed in a technical way, why the Series X can't run FSR4 Int8, when even a 6600XT can.
I never say it can't run it. Can you stop to be so childish. I said the TOPs number is so scarse on XSX which I doubt FSR4 will be the same as RDNA4. Nothing more.
