NVIDIA GeForce RTX 5080 to Stand Out with 30 Gbps GDDR7 Memory, Other SKUs Remain on 28 Gbps

[Dr. Dro]

That 28 to 30 Gbps increase is the GDDR7 memory between the RTX 5080 (and lower SKUs) compared to the RTX 5090.

The RTX 4090 has 21 Gbps GDDR6X memory and the 7900 XTX has 20 Gbps GDDR6. That bandwidth increase is pretty substantial aside from the bus increase. I think the RTX 4080 SUPER had 23 Gbps GDDR6X chips.

24 Gbps on both 4080 and 4080 Super. 21 on 3090 Ti and other G6X equipped 40 series (4070, 70 Ti, 70 Ti Super, 4090). 1st generation 21 Gbps chip with half density in 3090, 3080 and 3080 Ti use a 19 Gbps IC.

Will there be a Ti without any competition?

Super versions might come to appease shareholders in 2026.

In a normal world, where user would be much more considerate with their hard earn money, this card should be DOA, unless is priced as the current 4070, or less. By the specs, this is a 5070 on all, except name.
It is extremely obvious thst in the near future a better variant with 20 or 24GB of VRAM, and probably way wider bus, is going to be released. So this card will be easily forgotten.

GDDR7 uses PAM3 signalling vs GDDR6X's PAM4. GDDR7 has lower voltages as well.

Yes, GDDR7 is to G6X what GDDR6 was to G5X - a more refined version, or "final" version and AMD will use it as well, long time. GDDR6 was announced by Samsung for up to 24 Gbps speed's btw, not making it really inferior to G6X, but I never saw those versions on any graphics cards.

24 Gbps on both 4080 and 4080 Super.

Did these actually ever get those? Specs were for 22 and 23 IIRC.

Can't wait for the totally reasonable prices.
