Description:
Who might win the next-gen GPU war? And what basis will that war be fought
on, maybe more to the point...

FULL STORY ======================================================================

Weve had some new material float down from the GPU grapevine, theorizing how both the next-gen Nvidia Lovelace and AMD RDNA 3 graphics cards will pan out.

This comes from Greymon55, now a regular hardware leaker on Twitter, who has shared what they believe to be the likely core spec of the flagship GPUs from both Teams Green and Red although note the use of question marks with some
of the contended details, meaning that those parts are educated guesswork at this stage. Let me add more:N31=GFX11=5nm+6nm TSMC=120WGP 15360SP256bit 32G GDDR6 18Gbps?256/512mb Infinity Cache?=3D Infinity Cache2.4~2.5GHz?75T FP32? November 9, 2021 See more

Of course, this is an early stage rumor so all of it should be treated with a very healthy dollop of skepticism, but Greymon asserts that what will presumably be the RTX 4090 will run with 18,432 CUDA cores, plus 24GB of GDDR6X video memory and a 384-bit memory interface.

Clock speeds will be pitched in the area of 2.3GHz to 2.5GHz thats one of
the nuggets of info with a big question mark hanging over it offering something in the order of around 90TFlops of raw (FP32) performance (ditto on the question mark there).

Moving to the AMD RDNA 3 champion, this GPU is purportedly set to come bristling with 15,360 stream processors (cores), as previously rumored, and 32GB of GDDR6 with a 256-bit memory interface plus the key addition of 3D Infinity Cache to stay competitive with Nvidia, as we heard recently from Greymon (there could be 256MB or 512MB of Infinity Cache).

As you may know, 3D V-Cache or vertical cache meaning simply that its
stacked up vertically is whats coming to Ryzen CPUs with new models
(possibly Ryzen 6000 chips) at the start of 2022 .

Clock speeds for the next-gen AMD flagship, presumably the RX 7900, are roughly pegged at around the same as Nvidia 2.4GHz to 2.5GHz offering about 75Tflops of FP32 performance, Greymon reckons. Analysis: Worrying about the wrong thing

Wed be foolish to try to engage in any real comparative debate based on the above-rumored specs at this stage in the next-gen GPU game, so bear that firmly in mind. Still, its worth putting some tentative initial thoughts together, huge amounts of salt clutched in both hands.

So, the theory is that the RTX 4000 flagship will pull around 85-90TFlops of raw (FP32) performance. Now, the RTX 3090 comes in at 36TFlops, so thatd make its successor around 2.5x more performant, in theory: a huge leap.

On the AMD side, the RDNA 3 flagship is pulling a purported 75Tflops, as noted, which isnt far off Nvidia, but its a bit behind. However, even if
these figures are in the correct ballpark which is obviously a big if that performance metric does not equate to real-world gaming performance.

Weve also heard this week that Nvidias next-gen graphics cards could be twice as powerful as current models , and these purported specs look to back up
this assertion. And with AMD set to crank the cache (and use that 3D V-Cache, of course), plus adopt a fresh multi-chip module strategy with the RX 7900, according to previous rumors, Team Reds flagship could also turn out to be ridiculously powerful as weve reported before.

The reality is that it sounds like both Nvidia and AMDs next GPUs are shaping up very nicely, and will represent big jumps in performance above the current graphics cards on both teams.

The real worry, perhaps, is not exactly how powerful these cards will turn
out to be in comparison to each other, but how much they will cost. Indeed, the true next-gen GPU battle may be fought on value proposition and availability (if component shortages continue as predicted) and indeed with power consumption being a further concern (and its here that what weve been hearing about Nvidia in recent times is rather alarming, condiments aplenty
of course). Find the best Nvidia GPU for you
