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.
Rumor: Ryzen 7000 processors all get integrated graphics - 04/06/2021 08:49 AM
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 The performance is however based on the outdated AOTS (Ashes o...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...

Hmm maybe they mean ray traced performance vs their current tech. If it's raw performance, I call bs.

BS on what?
Rumours are saying they are going MCM design with two 80CU dies thats 160CU's that is them basically strapping 2 6900XT's together. Then add on clockspeed improvements from 5nm process, lower engery and better efficiency. Then also add in more (and probably faster) IF cache, and then add on improved IPC gains and general architecture changes and probably faster VRAM too and a wider bus....?
Could this lead to 3x the performance on paper as it stands, I don't see why not.
Could the whole rumour be BS sure.

...I have an hard time believing this rumor. I'll have to see it to believe it.

don't see anything weird about mine and frankly your post seems to validate it
you're specifically mentioning 4th gen 5400G as a better choice than 6700k,exactly because it took them a couple of generations to get the ccx-ccd communication speed to this level.
CCX-CCD is not the main problem with the performance difference between Zen and a 6700k, a 4 core Ryzen is only one chiplet anyway.
The clock difference was a much bigger problem for AMD.
Comparing a future 5400g and a 6700k shows that a lot has happened.
The 5400g could be 20% faster then 3400g like the rest of the 3000 to 5000 generation jump, and i am guessing it would cost 20% more.
The street price of a 3400g is half of the MSRP of a 6700k (dont know the 6700k street price), so a 5400g would be twice as good in performance/€ compared to a 6700k.
This future 7900XT, if it is 2 refined 6900XTs "glued" together it should theoretically cost twice as much as a single refined 6900XT chip with the name of something like 7800 or whatever that would be called.
I would be much more hyped about a potential refined single chip card, that still has more performance then the top 1-2% of the world, but without the potential Crossfire or CCX-CCD problems that 2 chips could cause.

Like any of us care...
It would be more intriguing if the title said,
Rx7900xt would be 3 times more available than Rx6900XT
each chiplet sold individually
also,am I the only one here thinking that bringing a mcm design gpu earlier than expeccted is more likely with miners not gamers in mind ?
