Nvidia and AMD are currently working on their next generations of GeForce RTX and Radeon RX. New rumors appear. They address several issues, including video memory.
The next family of GeForce RTX graphics cards will not necessarily be called the GeForce RTX 40 series. This name is now “timed” by various indiscretions. Nvidia is likely to adopt the GeForce RTX 50 series name for its Ada Lovelace generation. kopite7kim please mention these solutions as **90/**80 etc., in case they are not called RTX 40 but RTX 50.
GeForce RTX Ada LoveLace
The new video memory speculation evokes not 24 Gbps but 21 Gbps. We would find ourselves with a profile identical to that offered by the new GeForce RTX 3090 Ti. The thermal envelope must reach 600 Watts. This figure is plausible with respect to the PCIe 5.0 connector installed on the current 3090 Ti.

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

Radeon RX RDNA 3 (Radeon RX 7950 XT?)
On the AMD side murmur that the upcoming Navi 31, the flagship GPU of the RDNA 3 family (Radeon RX 7950 XT?) will be equipped with 7 chipsets. Not everything is very clear on this topic. Typically, AMD is supposed to use a multichip module MCM contraction approach with 2 GCDs (5nm) and 4 MCDs (6nm), all accompanied by an IOD.
This hypothetical Radeon RX 7950 XT Navi 31 GPU should offer 15,360 stream processors powered at 2.5 GHz. We do not know if this frequency represents the maximum possible value or the base. 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 at FP32, a nice +67% over the Radeon RX6900XT. The card should be accompanied by an imposing TDP of 500 Watts, again a 67% increase compared to its predecessor.
On the equipment side, it is not impossible that the RAM offers 32 GB, which is double that of the current AMD flagship. The operation of this GDDR6 at 21 Gbps would be ensured by a 256-bit bus. Similarly, the Infinity Cache should also be doubled (512 MB).
Here’s an initial review based on rumors from VideoCardz.
