Rumor: Radeon RX 7900 XT would be up to 3 times faster than the Radeon RX 6900 XT
There are a number of rumors on AMD's next-gen Radeon RX 7900 XT graphics cards. Take it as such, rumors. RDNA3 would offer a significant performance jump thanks to the implementation of a chiplet design like the Ryzen.
It is indicated that the next AMD flagship would be the first model of the Radeon RX 7000 series to adopt such a design, which would consist of two GPU's holding 80 CUs each (5120 Shader Processors), these would communicate over an I/O die. pretty much what you're seeing with Ryzen. The GPU would be Navi 31 and could be 2.5 times faster than Navi 21 (RX 6900 XT). The leaker, Yuko Yoshida, mentioned that performance improvement would be even greater, based on RDNA3 and 5nm fabbing.
It's speculation of the highest degree though. Personally, I don't see multi-chip design working well for graphics cards due to reasons of latency, cache, and complexity. Then again, we never would have thought that Ryzen would work out so well either. For now, this is a lot of gossip and hearsay though. As it stands the way I see it, now next-gen GPUs still aren't expected till the end of 2022 maybe even 2023.

The rumor mill the past years has been in 6th gear, and apparently, we're now already talking Ryzen series 7000/ ZEN4. It's a fresh rumor though. See One difference between Intel and AMD is that all...
Rumor: Radeon RX 6000 Series as fast as a standard RTX 2080 Ti? - 09/14/2020 04:10 PM
Alleged performance of AMD's next-generation Radeon RX 6000 series graphics cards based on RDNA 2 GPU architecture allegedly has leaked. The performance is however based on the outdated AOTS (Ashes o...
Rumor: Radeon RX Vega cards Look to be Insanely good crypto-currency miners - 08/04/2017 09:52 AM
Gamers beware, rumors now indicate that the Radeon RX Vega cards might be insanely good crypto-currency miners. And that will be a problem as miners would purchase them for above average prices, which...

rtx is stopgap raytracing.
rdna2's raytracing is non existent.
it's still too early to judge who,if anyone,is "left in the dust".
what i'm sure of is there will be no possibility to put three 300w navi21 dies on a consumer product,if this is three chiplets then it's 100w each.
neither has mcm been ever been tried before and I'm pretty sure for game engines and api's this will not be just another new architecture.

I see the Infinite Cache on RX 6000 as one step toward an MCM design. In that respect Nvidia's design is much more traditional. Although Nvidia's GPUs still seem to work for them, especially toward higher resolutions, partially thanks to the larger memory bandwidths (compared to AMD), that traditional design is still something they need to step away from to make MCM work. AMD would have learned a whole lot from Ryzen that is directly and straightforwardly applicable to MCM GPUs as well. It's been a relatively long time in computer technology terms since the first Ryzen was released, yet Intel is still not ready to release their own equivalent. That's how long it takes to nail it down even on the CPU side, where things don't need to be as smooth. Depending on when exactly Nvidia began developing their MCM GPU tech, who knows how much work they still have left, having started from scratch.

Ahh yes, these kind of very early rumors - they really oftern proof as wrong afterwards. I guess 3 times faster would be very very optimistic. The question is in which area. Maybe in Raytracing with some sort of DLSS - Then it could be true and maybe on par with nVidias next Gen. Anyway - I hope the next Gen would be better available and cheaper. If yes, it was a great thing to sell my 5700XT for 600 bucks, a couple of weeks ago

and now go upgrade to 6700xt for 1000
I don't get people being so happy with how much they sold their cards for if getting a new gen card would cost them an even more ridiculous premium.

What worries me is the availability of any hardware in couple of years, will it improve or just degrade even further, my actual target was to get 6800xt but the availability of it was next to none in my country and when it was available it was about 1.5X more than what i paid for 3070 which i am not entirely happy about. AMD is doing a great work presently giving us some great future with their hardware but these paper launches worry me even further as i look forward to full build upgrade which might not happen anytime soon.
