AMD Navi 21 XT Seemingly Confirmed to Run at ~2.3, 2.4 GHz Clock, 250 W+
AMD's RDNA2-based cards are just around the corner, with the company's full debut of the secrecy-shrouded cards being set for October 28th. Rumors of high clocks on AMD's new architecture - which were nothing more than unsubstantiated rumors up to now - have seemingly been confirmed, with Patrick Schur posting on Twitter some specifications for upcoming RNDA2-based Navi 21 XT. Navi 21 XT falls under the big Navi chip, but likely isn't the top performer from AMD - the company is allegedly working on a Navi 21 XTX solution, which ought to be exclusive to their reference designs, with higher clocks and possibly more CUs.
The specs outed by Patrick are promising, to say the least; that AMD's Big Navi can reach clocks in excess of 2.4 GHz with a 250 W+ TGP (quoted at around 255 W) is certainly good news. The 2.4 GHz (game clock) speeds are being associated with AIB cards; AMD's own reference designs should be running at a more conservative 2.3 GHz. A memory pool of 16 GB GDDR6 has also been confirmed. AMD's assault on the NVIDIA 30-series lineup should embody three models carved from the Navi 21 chip - the higher performance, AMD-exclusive XTX, XT, and the lower performance Navi 21 XL. All of these are expected to ship with the same 256 bit bus and 16 GB GDDR6 memory, whilst taking advantage of AMD's (rumored, for now) Infinity Cache to make up for the lower memory speeds and bus. Hold on to your hats; the hype train is going full speed ahead, luckily stopping in a smooth manner come October 28th.

229 Comments on AMD Navi 21 XT Seemingly Confirmed to Run at ~2.3, 2.4 GHz Clock, 250 W+
$599 and just within 5% to 15% to the RTX 3080, just like how the RX 5700 XT was to the 2070 Super. Enough RAM and optimized memory bandwidth (from the supposed Infinity Cache) to run games at 4K pretty well.
For sure it should best the RTX 2080 Ti and beat the upcoming RTX 3070 in 1080p/1440p performance.
The AMD fine wine attacked again (new uArch so of course big gains over time).
Also I own a 5700 XT and it does match up.
Can't really make a Super/Ti variant, so Nvidia's only option will be price cuts (depending on where AMD price of course, but I'm expecting AMD to want to recoup market share, so with a product with a likely lower BOM cost, now's the time).
Even then, with how expensive many of those coolers look to make, that'll eat in seriously to Nvidia's margins.
5700XT gain a few % with PCIe 4.0 and 2070S lose a few % with 3950X vs 10900K, some game even run very poorly with 3950X
Also HUB refuse to include DLSS 2.0 results, which RTX users will gladly use on any title that support it.
Kinda unfair to use feature available on one card (PCIe 4.0) but refuse to do the same with the other (DLSS).
Now that Cyberpunk 2077 is about to release, I wonder what 5700XT owners are gonna feel though, imminent upgrade to Big Navi ? The CP2077 HypeTrain is going stronger and stronger everyday :D
DLSS 2.0 is still currently limited to a very small amount of games. If/Once DLSS 2.0 (as lets be honest, 1.0 is trash) gets good penetration across a variety of games, its kinda ambiguous to include it in benchmarking.
Just saying, not really fair a comparison when you use a feature that is available on one (PCIe 4.0) but refuse to do the same for the other (DLSS). It's not like RTX users are leaving DLSS 2.0 OFF in any game, 5700XT owners however might have to use PCIe 3.0 to fix the black screen bug.Not really, you can check HUB PCIe 3.0 vs 4.0 benchmarks, even the 5700XT can gain 5% with PCIe 4.0
Every optimization is a performance trick, do you really care when it give the same Image Quality ?
If no one explained how DLSS work, you would just consider it an optimization like anything else.
Besides, HWU at the end of every benchmark I've seen of them from late have included DLSS numbers separately in the same review so people can work out for themselves if they would prefer the performance at an upscaled resolution. DLSS is very good, but by its nature, isn't lossless.
Edit: fell free t check this to a;y kind of advantage PCU 4 offers...

It's the end result that matter, as long as Image Quality is equal, people couldn't care less about any optimization.
Work smarter, not harder :D
Every hardware editorial seems to agree that if DLSS is available, use it. They didn't say anything about trading visual quality for performance (as least with DLSS in Quality mode).
The only thing with DLSS is that it's unfair to AMD, who has no answer yet. But it's a competition out there, not some fun race between friends.
Let think of it this way, while AMD continue to optimize rasterization performance for their GPU, Nvidia effort is to incorporate DLSS into new games. But somehow benching DLSS is too unfair for AMD, it makes no fricking sense.
Also equal settings and equal conditions were never actually equal, some games just have optimizations for specific brand, just like Far Cry 5 feature rapid-packed math.
