Samsung unveiled a newer GDDR6W memory standard that can deliver up to twice the performance, memory capacity, and memory bandwidth as compared to the standard GDDR6 and GDDR6X modules.
Nvidia recently decided to swap out the GDDR6X memory on the RTX 4070 GPU for slower GDDR6 modules instead. Apparently, it had a hard time sourcing GDDR6X memory but had a lot of GDDR6 lying around.
Quietly and without much fanfare, Nvidia announced a new variant of the RTX 4070 graphics card. It is almost identical to the original version, minus the memory standard—GDDR6 instead of GDDR6X.
Samsung has outlined more details about its upcoming GDDR7 memory standard in a recent company presentation, with these upcoming DRAM modules offering far more bandwidth and memory capacities.
New RTX 4070 GPUs are on the way, downgraded from GDDR6X to GDDR6 memory, but the packaging may not make it so obvious.
As Nick explained, the reason why this is happening at all is thought to be a short supply of the GDDR6X graphics memory used by the existing RTX 4070. Indeed, Nvidia's announcement implies just that.
In context: As manufacturers continue to squeeze every last drop of performance out of current GDDR6 and GDDR6X memory modules, Samsung has announced a new and improved entry to the family --- GDDR6W.
The GeForce RTX 4060 and the GeForce RTX 4060 Ti, two popular current-gen graphics cards, are expected to be unaffected by the reported GDDR6X issue as they use standard GDDR6 memory.
Base/boost clocks are listed at 735 MHz/2,490 MHz. While memory is doubled to 48 GB its GDDR6 modules are clocked slower at 864 GB/s whereas the GDDR6X of the RTX 4090 is just over 1 TB/s.
Nvidia's RTX 4070 with GDDR6 memory is slower yet costs the same as the GDDR6X version, according to an online listing.
