After NVIDIA, the new generation of graphics cards is preparing to take over at AMD as well.
Although difficult to obtain, the release of the GeForce RTX 4090 from NVIDIA has opened the ball for the new generation. A ball that should see AMD land next week.
The delay of the Navi 32 and Navi 33
Pending the official announcement set for November 3 at 9 p.m. French time, various rumors have emerged. The most important of them evokes a strategy similar to that of NVIDIA.
If it would be a question of introducing the new RDNA 3 architecture, AMD would therefore not have the idea of launching a whole range of graphics cards either. Only the most powerful model would be released.
Baptized “Radeon RX 7900 XTX”, the card in question would bring out from the boxes a suffix that AMD had not used since the Radeon X1000 series and would above all confirm the lag of the Navi 32/33.
A TDP of 420 Watts for Navi 31
According to the latest rumors, the Radeon RX 7900 XTX is designed around the Navi 31 GPU, which integrates 12,288 stream processors through an MCM construction or multi chip module.
The principle here is to combine several logic chips within a single package and if it would be used for the first time on a GPU, AMD has good experience of this, with CPUs in particular.
Navi 31 is based on TSMC’s N5 etching process (5 nm EUV) and is associated with a GDDR6 memory controller engraved in N6. It has a 384-bit interface bus for 24 GB of GDDR6 at 20 Gbps.
Rumors suggest a total bandwidth of 960 GB / s while the TDP would be around 420 Watts, very close to the 450 Watts of the GeForce RTX 4090. To see with which socket (s) AMD intends to power the thing: classic 8-pin or the new ATX 12VHPWR?
