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.

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.

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.

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.

This will allow a 256-bit GDDR7 memory module based on the newer standard to match the bandwidth of a 384-bit GDDR6 VRAM module. The upcoming GDDR7 memory standards will allow for up to 1152 GB/s ...

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.

The ADA-based RTX 4090 launched in October 2022 with 16,384 CUDA cores/512 tensor cores, 24 GB GDDR6X memory at $1,599. RTX TITAN ADA vs RTX 6000 ADA vs RTX 4090 Images: FluxRBLX (via Reddit) ...

Samsung is cooking up 24Gbps GDDR6 DRAM, and the new modules will help enhance the abilities of next-gen GPUs. The company says its new memory will be the “first GDDR6 to deliver speeds up to ...

Samsung says the new modules support 1.1V of power, as opposed to the industry standard of 1.35/125V. It using a new dynamic power switching technology to switch back and forth when necessary.

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.

Micron claims that GDDR6X’s per-pin data rate of 21Gb/s, when you combine all those pins and memory modules on something like the RTX 3090, the GPU has a total memory bandwidth of 936GB/s.

Micron's GDDR7 memory is expected to replace both GDDR6 and non-standard GDDR6X chips currently used in modern GPUs for gaming and AI workloads. The Idaho-based company claims ...
