Nvidia GeForce RTX 5090 rumors suggest switch to GDDR7

Nvidia's next-gen flagship graphics card reportedly to use GDDR7 VRAM along with a 384-bit memory bus, for 1.5TB/s memory bandwidth.

Nvidia GeForce RTX 5090 rumors

We’re still expecting it to be a year or more before we see Nvidia‘s true next generation of graphics card, which we would expect to be called the GeForce RTX 5000 series. However, that hasn’t stopped us hearing regular rumors, and the latest Nvidia GeForce RTX 5090 rumor suggests the card will use a new GDDR7 VRAM standard for never-before-seen levels of memory bandwidth.

The new memory standard was debuted by Samsung back in June 2023, with it detailing the higher 1.5TB/s potential bandwidth of the standard when configured with a 384-bit bus: a 40% increase over GDDR6. This would give the new best graphics card contender a massive increase over the existing RTX 4090, which boasts a 1.1TB/s memory bandwidth.

Not only does GDDR7 bring with it more bandwidth, thanks in large part to its higher 32Gbps per pin speed compared to the 24Gbps per pin of GDDR6, but it delivers this speed with a 20% reduction in power consumption too. We’re sure the next-gen Nvidia GPU will still draw plenty of power at peak but a little saving here and there is always welcome.

The latest leak comes via regular GPU story leaker, @kopite7kimi, along with @mango_ra, both of whom can be found on X/Twitter. In a discussion between the two users, they also mention the expected RTX 5090 GPU, which is thought to be the GB102. The GB refers to ‘B’ of which refers to the Blackwell architecture that is expected to power the new GPUs.

Previous RTX 5090 rumors have suggested GB102 will be 1.7x faster than the RTX 4090 and will include 24,567 CUDA cores, up from 16,383 of the 40 series flagship. This also follows some general RTX 5000 series rumors that speculate that early 2025 will be the arrival time for these graphics cards, though more recent speculation suggests that the RTX 5000 series release date could be this time next year.

It’s difficult to get too excited about a graphics card launch that’s quite so far away at this stage, especially with the RTX 4000 Super series just around the corner, but it’s certainly interesting to see just what leaps in technology and performance might be incoming.
