NVIDIA to Upgrade Memory Sizes for RTX 50-series SUPER GPUs

NVIDIA is planning to utilize 24 Gbit (3 GB) GDDR7 memory chips and enhance memory capacities for its upcoming RTX 50-series SUPER line of GPUs expected to launch later this year. According to leaked specifications of the GeForce RTX 5070 SUPER, the card will boast 18 GB of memory, achieved through six 24 Gbit memory chips connected via a 192-bit wide GDDR7 memory bus. The card is identified by the SKU "PG147-SKU65" and ASIC code "GB205-400-A1."

In addition to the increased memory size, the RTX 5070 SUPER is said to fully utilize the "GB205" silicon it is built on, allowing for all 50 SM to be active. The current RTX 5070 has 48 out of 50 SM enabled, resulting in 6,144 CUDA cores. With all 50 SM enabled, the RTX 5070 SUPER is expected to have 6,400 CUDA cores. This slight boost in shader count will be complemented by the 50% larger memory size and potential enhancements in GPU boost speeds. However, the memory bandwidth will remain the same at 28 Gbps, providing a bandwidth of 672 GB/s. The TGP (Total Graphics Power) is set to increase to 275 W, up from 250 W.
