Next-gen Nvidia RTX 5000 GPU rumored to apply GDDR7 reminiscence on a 384-bit bus

Rumor mill: Recent trends inside the DRAM enterprise advise GDDR7 will possibly be prepared for primetime whilst the subsequent technology of fanatic-class photographs playing cards come to marketplace. However, the quantity of reminiscence the upcoming flagships will function stays unsure, and the records to be had to depended on leakers keeps on changing.

Well-acknowledged leaker Kopite7kimi lately retracted an in advance declare approximately the reminiscence for the pinnacle-end model of Nvidia's upcoming Blackwell lineup, in all likelihood to be named GeForce RTX 5090. The modern data suggests it's going to still be most of the first merchandise to shift to GDDR7 VRAM, but it's going to in all likelihood feature the same amount of memory as the contemporary version.

A September leak counseled Blackwell's flagship GPU, the GB202, could function a 512-bit memory bus, indicating a product with 32GB of VRAM. Kopite7kimi now admits he in all likelihood miscalculated the quantity based totally on the specs of the Ada Lovelace structure. The revised prediction equals the RTX 4090's 384-bit bus, meaning 24GB of video reminiscence.

However, Kopite7kimi maintains that VRAM may be GDDR7, which ought to offer a giant pace improve as compared to the GDDR6X reminiscence that Nvidia's high-end GPUs currently use. Information concerning RAM speeds hasn't emerged yet, but early GDDR7 products could reach 32 Gb/s, a great boost over GDDR6X's 22-23Gb/s. Further revisions should sooner or later push GDDR7 to 36 Gb/s – a 50 percentage leap over GDDR6.

Prior facts on GB202 cautioned the RTX 5090 might have 50 percent more cores, fifty two percent extra memory bandwidth, seventy eight percentage extra L2 cache, and a fifteen percentage better frequency than the RTX 4090 for a 1.7x overall performance development. This could suggest roughly 24,000 CUDA cores, a 2.9 GHz enhance clock, and 128MB of L2 cache.

Kopite7kimi believes GB203 will probable seem in some high-give up Blackwell playing cards and could use a 256-bit reminiscence bus, similar to the 16GB RTX 4080. It's yet unclear if it will likely be GDDR7, GDDR6X, or probable the upcoming GDDR6W, which may be every other alternative for next-gen GPUs. Current rumors do not say whether or not all Blackwell playing cards will keep the identical quantity of memory as their Lovelace opposite numbers, which would be disappointing for the mainstream tiers.

The first GeForce RTX 5000 GPUs are expected to launch someday in 2024 at the earliest, alongside the first products to reach with GDDR7. However, we've got additionally seen rumors and a leaked Nvidia roadmap that factors to a possible put off into 2025.
