SK hynix says it's working on 3GB GDDR7 modules, just in time for GeForce RTX 50 SUPER cards

SK hynix has confirmed that it's cooking up higher-capacity GDDR7 memory modules that will roll out later this year, confirming it is increasing the maximum capacity of its GDDR7 from 16GB (2GB per module) to 24GB (3GB per module).

The South Korean memory giant commented on its larger 3GB GDDR7 memory modules for AI GPUs, but we know that we'll see 3GB GDDR7 memory modules arrive on desktop gaming GPUs like NVIDIA's upcoming GeForce RTX 50 SUPER series GPUs that have been in the rumor mill for months now.

We should see NVIDIA release a new GeForce RTX 5090 SUPER with a possible 48GB or even 64GB of GDDR7 memory, the RTX 5080 SUPER has been rumored with the full GB203 GPU and a larger 24GB of GDDR7 at 32Gbps and 420W+ of power. The RTX 5070 SUPER is rumored with 18GB of GDDR7 in the future.

The use of 3GB GDDR7 modules also makes it easier to use less GDDR7 memory modules, where a 24GB card would need just 8 modules (8 x 3GB = 24GB) instead of 12 (12 x 2GB = 24GB). This would also assist in reducing power consumption, thermals, and most of all: cost.

Samsung has had its beefed-up 3GB GDDR7 memory modules on sale in China for a little while now, fueling rumors that we would see the RTX 5090 SUPER with 48GB of GDDR7, with more on that in the story below.
