Both Navi 21 "Big Navi" and Navi 22 said to feature more VRAM than the RTX 3080

[midian182]

Rumor mill: With Nvidia’s Ampere cards receiving plenty of praise coupled with high demand, the tech industry is waiting to see AMD’s response. Team red will unveil its next-gen graphics cards on October 28, and we’ve once again heard that the flagship will sport 16GB of VRAM, while the model below it will come with 12GB of video RAM.

The latest claim comes from prolific leaker @_rogame, who tweeted that they had “confirmation” of both Navi 21 and Navi 22 GPUs. In the case of the former, which is based around the Big Navi design used in the flagship Radeon 6000 series, including the Radeon RX 6900 XT, it will feature 16 GB of VRAM.

I've now got confirmation for both :

> Navi21 16GB VRAM
> Navi22 12GB VRAM

I have no idea if these are full die or cut down SKUs

This isn’t the first time we’ve heard about Navi 21 featuring 16GB of RAM. Last month, tech analysis YouTube channel coreteks tweeted the same claim, adding that AMD had priced the card at $599 but dropped it to $549 following the Ampere reveal.

Other leaks, based on an alleged engineering sample, claim Big Navi will use Samsung's GDDR6 memory across a 256-bit wide bus interface.

Rogame wrties that the cheaper Navi 22 GPU will feature 12GB of RAM—possibly across a 192-bit interface. They admitted to being unsure whether these two confirmed variants are based on the full GPU dies or cut-down SKUs.

If the Big Navi claim is true, it would mean the RDNA 2-based card features double the memory of the RTX 3070 and 6GB more than the RTX 3080. However, it still falls short of the massive 24GB boasted by the RTX 3090, and we’ve just heard that an RTX 3080 variant with 20GB and an RTX 3070 with 16GB of VRAM are on the way.

Nothing about the Radeon 6000 series is confirmed, other than the cooler design—presumably for the flagship—that AMD tweeted, so we could see different VRAM amounts and bus specs, such as 512-bit and 384-bit. All will be revealed on October 28.

As far as I can tell, my 3080 runs 4K just fine. Gonna make a run for the 3090 on Thursday.

I will, of course, be awaiting a "big navi" vs. 3080/ 3090 comparison.

*enters the 3070 & 3080ti*

Re 3080Ti: Which specs and price though? For the 2080Ti nVidia could go from TU104 - 102 but the 3080 is already on GA102.

Probably around 1000 to 1100 USD to sit between 3080 and 3090. The extra 4GB VRAM that it will have over the AMD cards will be worth it and also 254bit BUS vs 320+bit.

However 3070ti will compete for pricing / performance for sure if 3080ti does not.

 

[Lew Zealand]

The market segmentation should be pretty clear:

Nvidia 3070 & 3080 for excellent performance per dollar, and may give up a few frames at 4K in the future
Nvidia 3070Ti & 3080Ti for similar excellent performance and for people who want to pay more for future-proofing. The fun part about futureproofing is that it's a fool's errand. No Ti cards for me thanks, even if they somehow have a few more CUDA cores stuffed in.

If the AMD pricing changes rumors are real, it suggests that Big Navi cannot compete directly with the 3080 and needs a price cut accordingly. But then nobody will buy an AMD 6090 if it can't compete with a 3080, even with 1.5x the VRAM.

Which means that a 20GB 3080Ti would be a *great* marketing cash grab, targeted at people who are bothered by other people having something better (VRAM) than what they have.

I would be more concerned if AMD's top parts only have a 256 bit memory bus. That would surely leave them at a disadvantage as the resolutions rise.

They will still have impressive bandwidth but nothing like the level a 3080 pushes, which would surely be heavily tested at 4K and future ray tracing implementations.

But if the first benchmarks are true that the 3090 only offers 10-15% over the 3080 where would that place a 3080ti ? Six percent more performance for $400 extra ? If it‘s „only“ $ 1,000, who would spend $1500 on a 3090 if you only get 4 GB extra RAM and six or so percent better performance for a 50% higher price ?

For Turing, they used a cut down Titan die for the 2080Ti instead of TU104 but the 3080 is already on that die (GA 102).

Going by the shader numbers, the 3090 is not going to be much faster than the 3080. It makes me wonder why the 3090 even exists. Unless you have a prosumer use for it, I think that you'd be better off just getting a Radeon RX 6900 XT and doing your own comparison. LOL

Why wait, buy one and do your own comparison, the more benchmarks out there, the better.

I sold my Radeon VII yesterday, now I will wait for Cyberpunk 2077 and whichever card upto £800 is faster in that game I will buy till then Xbox One X will be my friend : - P

What games have you played on it? How is that 10GB buffer?

Do you still have your 2080Ti?

 

[brruno]

And yet, they will have worse performance.
I rather have FPS in my screen than GB idling on the GPU ..

I started with CoD: MW with all settings at ultra to test the Ray Tracing. Then played part of Quake 2 RTX. Then CS Go and DCS World and MSFS 2020.

The 3080 definitely is getting higher fps than my 2080Ti.

YES I still have my 2080Ti... I resisted selling it because it still is a 1080p/1440p beast and I refuse to take a loss on it.

Good call there. I'd expect the 3070 to be faster than the 2080ti in the same fashion that the 1070 was faster than the 980ti.

Not enough for anyone to be able to tell visually, but the new value proposition is the story.

Could you do a test with 2080Ti maxed out vs that 3080 in 4K? The longer you keep it the more you will lose on it.

 

[Mr Majestyk]

Hard to believe that the 5700XT replacement will have a paltry 192 bit bus pushing it down to 3060 levels.

No-one sensible is going to buy 3090 ANYWAY(at least, not just for gaming - there will no doubt be niche uses), just like the titan cards it just exists to generate hype and for people who just want the fastest gaming card they can get with no regard to how much it costs.

For professionals it could make sense since apps seem to run much faster.
Another task is to make the 3080 look better wrt price performance. And if someone buys it for gaming, all the better.
