AMD Radeon RX 7000 Series to Include 6nm Optical-Shrinks of RDNA2

AMD's upcoming Radeon RX 7000 series could include GPUs from both the RDNA3 and RDNA2 graphics architectures, according to reliable sources on social media. This theory holds that the company could introduce new 5 nm GPUs based on the new RDNA3 architecture for the higher end, namely the Navi 31 and Navi 32; while giving the current-gen RDNA2 architecture a new lease of life in the lower segments. This isn't, however, a simple rebrand.

Apparently, some existing Navi 2x series chips will receive an optical shrink to the 6 nm node, in a bid to improve their performance/Watt. Some of the performance/Watt improvement could be used to increase engine clocks. These include the Navi 22, with its 40 RDNA2 compute units and 192-bit GDDR6 memory bus; and the Navi 23, with its 32 RDNA2 compute units and 128-bit GDDR6 memory bus. The updated Navi 22 will power the SKU that succeeds the current RX 6600 XT, while the updated Navi 23 works the lower-mainstream SKU RX x500-class.
It's also conceivable that AMD uses the opportunity to update the display and media-acceleration components of the chips, as it's been doing with the latest applications of "Vega," such as the iGPU inside Ryzen 5000G processors. RDNA3, meanwhile, will likely power the two largest chips, the 5 nm "Navi 31" and the "Navi 32," which will be at the hearts of SKUs that succeed the RX 6900/6800 series, and the RX 6700 series.

While apple goes for 3nm meanwhile everyone else will get only 6nm in 2022? That is sad and bad. If this information is right.

The high end is rumoured to be 5nm, not 6nm

Bicker about re-brands and arguing who have done worse NV or AMD in that department. People will never learn just argue about meaningless things.
If this will boost performance and give a better value and a drop in price (hopefully) who cares?
If that is a dual chip which I think it will be, this is a good move.

eidairaman1The lower cards will be RDNA 2 and upper cards RDNA3.

Ellesmere was rebadged 3x.
I was talking about the lower cards.

"Theory" it is not confirmed.

Cheese_On_tsaotTo be fair, that GTS 250 was just an 8800 GT.
the whole gtx 700 series was a rebrand of the 600 series

basically the same thing amd did, i dont know why nvidia gets away with anything but amd doesnt


i guess its because nvidia buyers dont pay much attention to what they are buying as long as its the product every reviewer talks about

thats normal

A tall building wont use the same column thickness that a 5 story building would use even if you want it really bad to have more space avaliable, its just not posible at the time of construction


well same thing happens here, a mobile soc draws 1% of power that a desktop gpu/cpu does

This is not true, the GTX 770 is the only rebrand but with better memory modules.

Its the same, the memory just has slightly higher clocks, the rest of the series is a rebranded architecture if you want to be specific its same shit different core counts. Amd lowered prices instead of bullshitting with a rebranded architecture

I don't view optical shrink as re-branding to begin with.

And, oh boy, PS5 would benefit from it a lot, I think, having power consumption issues.
