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.

But I'll look again at those benchmarks and see if the numbers I remember are wrong.
Edit:
Just looked at this, the performance hit of RT+DLSS is the same on the 2080Ti and 3080 in 4k, as I remembered:
tpucdn.com/review/evga-geforce-rtx-3080-ftw3-ultra/images/control-rtx-3840-2160.png
The fact is that most next-gen games will be developed, tested and optimized for RDNA2 GPU's, and it would be naive to imagine this will have no influence.
I used the 3080 reference review.... and just RT since you never mentioned DLSS until now. DLSS is different than RT, bud. Tough to hit a moving target. ;)Anyway, I digress. The point(s) has(have) been made and users can do what they please with the information out there. ;)
What bothers me is that nVidia’s advertisement and presentation is making it look like a leap forward, when certainly is not.
Im not implying nor did infer (or straight up say) anything about DLSS. That was you. Please feel free to look at the results in your 3080/3090 review of your choice at TPU...again, DLSS was not ever mentioned by me. Please, take the time to do that. I did the math and came up with a different answer.. others support that assertion. The onus isn't on me... the math is there in the review I mentioned. I don't see it any different in the latest review (so long as you stay in the lane of RT/1440/no DLSS) considering all 3080 reviews were on 9/16 or 9/17 here at TPU (according to google). Again, DLSS isn't RT so I'm not sure why that is even being brought up at this point.
PS - It holds true in 4K on your review. ;)

Thanks for registering to say that. Very helpful indeed.
As pointed out by many in this thread, a very small portion of users were actually affected and after the fact retracted their claims as the those users found out that it was something else causing the issue not the card or drivers, others just hopping on the bandwagon and exaggerating things. The latter group is YOU.I'm not dismissing that there are issues but problems of others aren't mine.I'm a fanboy for disagreeing and pointing out your gross exaggeration? If that's what it takes to be a fanboy then I'm a fanboy. Vote me.No one asked, no one cared, and how does that preclude you from being biased as hell? Sus, if you asked me.Says he has a crappy experience with a trash product and sticks with the same brand and is accusing others of being a fanboy. I'm gonna vote fanboy.
as I said : a waste of time.
That thing still runs like a champ, my little brother plays minecraft on it nearly everyday.
That little 4770 has been pumping out frames and generating joy for over 10 years.
The 2 GPU card rivals may have the same TotalBoardPower (~320W) but lets not forget that 3080 uses GDDR6X that draws the hefty amount of ~70W vs the 20~30W that "simple" GDDR6 draws.
Big navi 536mm2 will sell for ~$699, will need pcb, vram and vrm. To the cost add the waaay lower yield due to the muuuch higher size.
In case people wonder why AMD putting so much more effort into the CPU business.
Hope the new hardware just works like the RX580 and has no driver bugs please!
