High-end GPU rumors are popping up almost every day now. But most of them have been referring to Nvidia’s high-end cards, as their speculated increase in energy consumption and that they have entered the testing phase. Well, the high-end AD102 GPU anyway.
News about AMD’s next-generation RDNA3 cards has been less publicized. We know that high-end GPUs in the range will be chiplet-based designs but there is little concrete information beyond that. extraordinary leak Greymon55 is reporting that the internal specs of RDNA3 GPUs are different from previous leaks. The new rumors indicate that the GPU shader count will be lower than previously expected.
The flagship Navi 31, likely known as the RX 7900 XT, was previously rumored to have 15,360 stream processors and approach 100 TFLOPS. This new leak suggests that 12,228 shaders are now likely. That means 100 TFLOPS is pretty much impossible unless the card comes clocked really high or AMD has really done some internal magic to boost computing performance.
The Navi 32 GPU is expected to end up inside boards with the names RX 7700 and 7700 XT. It is expected to come with 8192 shaders while the Navi 33 or RX 7600 series should contain 4096. It’s important to remember that AMD’s current flagship, the RX 6900 XT comes with 5120 shaders, so these new cards are expected to be very powerful, although of course we don’t know how all that raw shader power will translate to game performance.

High-end RDNA3 cards are looking like a game-changer for the GPU industry. The use of chiplets is not new. AMD already produces multi-chip-module (MCM) CPUs and has also released a MCM compute GPU . It gives you an idea of what to expect, but MCM designs for consumer graphics cards are a big step forward.
We’re still months away from the release of new AMD GPUs, so the specs can always change. Yields can determine final array settings. AMD may be able to use fully enabled arrays or may have to merge areas to maximize its supply of usable arrays. Perhaps these latest leaks are related to this need? Maybe not.
The design phase is likely to be essentially complete, the GPUs are up and running and in testing, with PCB and cooling designs and particularly driver development accounting for much of the remaining work.
RDNA3 graphics cards are expected to release sometime in the second half of 2022. It’s hard to believe it’s already May, so this release and Nvidia’s competing RTX 40 series will arrive quickly.
