Nvidia may release the RTX 5080 in 24GB and 16GB flavors — the higher VRAM capacity will come in the future via 3GB GDDR7 chips

A shipping manifest has cropped up featuring different SKUs for Nvidia's upcoming Blackwell RTX 50-series GPUs. Discovered by harukaze5719 on X, the manifest shows seven variants, meaning we could see multiple iterations of the RTX 5090 and RTX 5080 at the very least, possibly with varying VRAM capacities.

The manifest showcases six GPU SKUs aimed at "development and testing purposes." All seven feature varying codenames: 699-1G144-0030-TS1, 699-1G144-0050-TS1, 699-1G144-0045-TS1, 691-1G145-2030-TS1, 699-1G147-0070-TS1, 699-1G147-0050-TS1, 699-1G147-0045-EB1.

    I think the big takeaway here is the 3GB GDDR7 rumor. This capacity should have been possible with GDDR6 but never manifested as far as I'm aware. Given the shrinkage of bus widths I would love it if this became standard as 128-bit bus can be 12GB and 192-bit 18GB which would be a welcome change for midrange cards.

    3GB GDDR7 isn't a rumor though.
    It's listed in roadmaps and expected to come out in late 2024.
    (But seeing as we're already in late 2024, we might not see it on cards until early 2025 at the earliest.)

    Up to 32Gb GDDR6 is part of the JEDEC spec, but the products never materialized so I'm going with the "I'll believe it when it exists" mindset for GDDR7. I hope those timelines turn out to be reality.

    3GB GDDR7 is definitely coming. It's just a matter of when.

    It would be really funny if Nvidia's low-end comes out so much later than the 5090/5080 that they get to use it at launch. So you get 12 GB on a 128-bit card and so on.
