The GeForce RTX 5090’s reported 512-bit memory bus would eclipse the current RTX 4090’s 384-bit bus, and offer significantly more bandwidth. While the actual VRAM amount isn’t confirmed, it may also be as large as 32GB. With 16 memory modules at 2GB each, however, 32GB of VRAM would be likely.
The memory layout indicated for the RTX 5090 in the post is 4, 5, 2, 5, compared to 3,4,1,4 of the RTX 4090, with those numbers indicating how many chips reside in the board area around the four sides of the GPU.
Gamers, creators, and budding AI engineers will all likely be pleased by the possibility of next-gen GeForces having larger memory capacities. There are obvious benefits for gamers that play at high resolutions, with the highest image quality settings and ray tracing. Content creators and 3D graphics artists working with ultra high-resolution models would also benefit. Machine learning and AI use cases would also leverage as much VRAM as is available.
Other potential specs such as its power draw are not yet known, but rumors indicate that the GeForce RTX 5090’s consumption may be in the 600 watt range.
With such a dense VRAM layout to support massive amounts of memory, the GeForce RTX 5090 is shaping up to be a powerful successor to the RTX 4090. Its release should likely occur sometime before the end of 2024, or early in 2025, if current indicators are accurate. Pricing is also unknown at this time, but a $1599 MSRP similar to the GeForce RTX 4090 is likely.
