NVIDIA was reportedly preparing an upgraded GeForce RTX 4090 Ti graphics card, but it looks like the company could be skipping the RTX 4090 Ti and driving gamers right into its next-gen flagship GeForce RTX 5090... with a much wider memory bus than we had anticipated.
According to the latest rumours, NVIDIA's new GeForce RTX 5090 -- which should be coming out in 2025 -- will have a huge 512-bit memory bus resulting in an even bigger 2TB/sec of memory bandwidth, double the memory bandwidth than the current GeForce RTX 4090. Furthermore, we could expect either faster GDDR6X memory being used, or next-gen GDDR7 memory that we've been hearing more and more about over the last few months.
AMD could strike back with a new Radeon RX series GPU using its second-gen 3D V-Cache that it would borrow from its Ryzen CPU series, and NVIDIA being NVIDIA will mean they'll want to keep leadership in GPU performance, so the GeForce RTX 5090 on a huge 512-bit memory bus with 2TB/sec of memory bandwidth... yeah, that'll do it.
We haven't had a huge 512-bit memory bus on an NVIDIA GeForce GPU in many, many generations... so it would be quite the shift for Team Green to go in that wider memory bus direction. We're still at least 18+ months away from the GeForce RTX 5090 and GeForce RTX 5080 graphics cards being released, but the sheer tease of a 512-bit memory bus is exciting to say the least.
