Flagship Graphics Card, Nvidia Ada Lovelace AD102 vs AMD RDNA 3 Navi 31

Nvidia and AMD are currently working on their next generations of GeForce RTX and Radeon RX. New rumors appear. They address a variety of issues, including that of video memory.

The next family of GeForce RTX graphics cards won’t necessarily be called the GeForce RTX 40 series. This name has now been “temporized” by various indiscretions. Nvidia will likely adopt the GeForce RTX 50 series name for its generation Ada Lovelacekopite7kim list these solutions as **90/**80 etc, in case they are not called RTX 40 but RTX 50.

The new speculation around video memory does not call for 24 Gbps but 21 Gbps. We would suddenly have a profile identical to that proposed by the new one GeForce RTX 3090 Ti† The thermal envelope should reach 600 Watts. This figure is plausible regarding the PCIe 5.0 connector mounted on the current 3090 Ti.

Based on rumours

the GPU Ada Lovelace AD102 would consist of 144 SMs, a 71% increase over the current GA102 GPU! At the heart of its mechanics, no less than 18,432 CUDA cores would be in action, as well as even a 384-bit bus, which is enough to guarantee 1004 Gb/s bandwidth.

Radeon RX RDNA 3 (Radeon RX 7950 XT?)

On AMD’s side it mumble that the next Navi 31, the flagship GPU of the RDNA 3 family (Radeon RX 7950 XT?) will be equipped with 7 chiplets. Not everything is very clear on this subject. Normally AMD would use an MCM contraction approach of Multi Chip Module with 2 GCDs (5 nm) and 4 MCDs (6 nm), all accompanied by an IOD.

This hypothetical Radeon RX 7950 XT, its Navi 31 GPU, should offer 15,360 stream processors running at 2.5 GHz. We don’t know whether this frequency represents the maximum possible value or the base value. Meanwhile, this is an 11% improvement over the Radeon RX 6900 XT, enough to ensure, with other changes, a theoretical power of 38.4 TFLOPs in FP32, a nice +67% compared to the Radeon.RX6900XT. The card should be accompanied by an impressive TDP of 500 Watts, another 67% increase over its predecessor.

In terms of equipment, it is possible that the working memory offers 32 GB, which is twice as much as the current AMD flagship. The operation of this GDDR6 at 21 Gbps would be ensured by a 256-bit bus. Likewise, the Infinity Cache should also double (512MB).
