It seems that NVIDIA is thinking of using the next generation of RAM for its graphics cardsand it is that as we can read in ExtremeTechNVIDIA has its sights set on the GDDR7 memory for the next generation NVIDIA GeForce RTX 50 Series, thus increasing the memory bandwidth on these graphics cards.
The latest generations of GDDR6X memory are capable of speeds of up to 24Gbps, speeds that are already causing certain problems at the memory cooling level, but this comes to nothing if we take into account that GDDR7 will feature speeds of 36Gbps at launch.
Obviously, not everything rests in the hands of the memory chips, because NVIDIA GPUs must be able to make efficient use of this bandwidthsomething that we do not doubt that it can happen considering that NVIDIA has provided the RTX 4090 with a bandwidth of 1.05TB/s through a 384-bit bus.
For example, if NVIDIA puts a 256-bit bus on a card with GDDR7 memory, we should be able to expect speeds of around 1.7TB/sso we would definitely find ourselves in another world in terms of memory performance.
