There was also GDDR6X memory, used solely by Nvidia on higher tier RTX 30- and 40-series GPUs, with initial speeds of 19 GT/s that eventually reached up to 23 GT/s — at least in shipping products.

GDDR6X memory can be found in the GeForce RTX 4070 and above, so the shortage will also apply to t he newer RTX 4070 SUPER, the RTX 4070 Ti SUPER, the RTX 4080 SUPER, and the flagship GeForce RTX ...

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.

As standard, the RTX 4070 comes with 12GB of GDDR6X VRAM running at 1,313MHz (21Gbps effective), giving you a total memory bandwidth of 504.2GB/s with this GPU's 192-bit memory interface.

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.

That's according to speculation posted by Chinese tech site Benchlife, who goes on to speculate that if GDDR6X memory is in short supply, NVIDIA may produce a new variant of the GeForce RTX 4070 ...

The slide indicates that GDDR7 memory chips can deliver up to a 3.1x improvement over GDDR6 applications and a 1.5x increase over "best-in-class" GDDR6X applications.

NVIDIA's previous-gen GeForce RTX 4090 has 24GB of GDDR6X memory, but it has been modded with 48GB recently, and now we're hearing we're going to see custom RTX 4090s with a whopping 96GB of ...

It's worth reiterating that when it comes to changes, the GDDR6X RTX 3060 Ti isn't worlds apart from the original. It wields the same 4864 CUDA core count and GA104 chip, but ramps memory speeds ...

That's a very healthy boost over the fastest current GDDR6 and GDDR6X memory. That 36 Gbps figure is just the starting point, too. By comparison, GDDR6 kicked off at 14 Gbps.

The updated memory, GDDR6X, made its first appearance with the release of the RTX 3080 and 3090 models in September 2020. GDDR6X offers an increase in per-pin bandwidth as well as upwards of a 15% ...
