In a recent development, rumors are circulating about NVIDIA’s next-generation gaming GPU, the GeForce RTX “Ada-Next”, which is expected to feature a colossal 512-bit bus. This information comes from a leak by the well-known tech insider, Kopite7kimi.
While NVIDIA is reportedly discontinuing its flagship GeForce RTX 4090 Ti GPU, it appears that the company is already laying the groundwork for its successor. The leaked information suggests a significant upgrade to the memory configuration of the next-gen GPU.
The Ada-Next flagship gaming GPU, anticipated to launch in 2025, is rumored to have a 512-bit memory interface. This would be a significant leap from NVIDIA’s current GeForce gaming graphics card lineup, which hasn’t seen a memory configuration above 384-bit since the GeForce GTX 285, released in 2009.
A 512-bit memory configuration would allow NVIDIA to experiment with massive memory capacities. Presently, 384-bit bus graphics cards like the RTX 4090 and RTX 6000 Ada feature up to 24 GB and 48 GB capacities. With a 512-bit bus interface, capacities could reach 32 GB and expand up to 64 GB on a single card, marking a 33% increase in memory capacities.
It remains unconfirmed whether NVIDIA’s next-gen GPUs will utilize a GDDR7 memory standard or stick with GDDR6X for another generation. However, it would be imprudent not to adopt the newer technology, given that it is expected to hit mass production in late 2024. According to NVIDIA’s roadmap, the next-gen cards aren’t due until 2025.
