Next-gen NVIDIA "Ada" GPUs to Possibly Use 21 Gbps Memory

[VSG]

Everyone's favorite GPU-news leaker Kopite7kimi has updated his tweet from April 1 with more specific board part numbers, and suddenly the information contained there—which could have been misinterpreted as an April 1st joke—now all seems to add up with our own posting from last month about memory bus widths. The update seems to indicate the boards will now feature 21 Gbps memory, which is the same as what we saw on the recently made available RTX 3090 Ti cards, and Videocardz goes further to speculate the 3090 Ti could have been a dry run for the upcoming cards, including with a similar 600 W TDP rating to follow. Note also that the leaker is shying away from referring to these as the RTX 4080/4090 series, leaving room in case NVIDIA decides to jump in naming scheme for reasons including marketing and what the competition decides.

Im more exited for 4080 possibly having 20GB buffer. Finally. Having only 10GB for what is a 4K card would be stupid and not at all futureproof.
10GB these days is between low end 6/8GB and midrange 12GB. 16GB+ is the new high end.

They are still way too power hungry, the xx70 needing 400w alone is a bit mad. So if nVidia is recommending a 750w for a 3070Ti, then would a xx70 need a 900w one?

Yeh, let's hope that's not true, else i'm still gonna get a 3000 series card as i only plan on using 1440p anyways.

Hopefully it just means they're pushed past the sweet spot and undervolting can get some good results. For example 3090 Ti limited to 300W has better performance per W than 6900XT.

With chips pushed to the limit and mainstream overclocking as good as dead if feel like undervolting/underclocking is the future. Save 200W by losing 5-10% of performance? Acceptable tradeoff i say.

Yeah, so dry it will make your PSU rot and crumble to dust. If things keep going in this direction, FPS gaming on a PC is going to end up being only for an elite few and eventually die out altogether. I mean, who in their right mind wants to be gaming with a space heater in the same room all year round? I'm able to keep the room temp just under control with the two monster cards I have using a window fan for now(until I get tired of wasps getting in and possibly stinging my ass). I can't imagine how big of an AC unit I would need during the summer months 5-7 years from now to keep the room at 72 F with a newer system, not to mention the possible electrical work needed to upgrade the circuit & maybe a whole new UPS to handle the higher wattage.

Unless things have or will dramatically change in the market, I would postulate that gaming companies want individuals to spend money on their games instead of power-hungry graphics cards. Just throwing that out there for thought.

if this can be believed, then every card on that list will be using plain-jane GDDR6.

So why does it have the same level of power whore-down as this new 24-chip 3090 Ti?

Imagine if they all had Nvlink.

I remember when R9 295X2's 500W TBP was considered insane and that was a dual GPU card.

Nvlink to do what? The only real use for that nowadays would be in workstations for rendering & scientific apps, and those that perform such tasks typically opt for workstation-type cards that use less wattage. I would imagine if they had Nvlink, you would need multiple high-wattage power supplies to run more than two of them and probably some kind of DIY kit bashing liquid cooling.
