Some facts from someone who would buy NV or AMD:

if you think Nvidia made a poor choice with 8nm Samsung, reconsider. The transistor density is so far higher (45.1M / mm²) than 7nm RDNA 2 console GPUs (42.5M / mm²). Theyve boosted performance from the last gen by ~50%, with just a 50% increase in transistor count (from RTX 2080 TI to RTX 3080).

Turing GPUs were build with transistors with just 24.7M / mm².

8nm does not necessarily mean worse than 7nm.

The RDNA2 based consoles are an SOC which has a CPU and other logic taking up nearly half the die space.CPUs tend to have much lower transistor density. Apparently the 56CU RDNA2 GPU is taking up around 170MM2 of the SOC. Now compare that to RDNA1,which was a pipecleaner like Vega 7 was(it was delayed by nearly 6 months apparently). Navi10 was a 40CU GPU and around 251MM2. The main advantage TSMC 7NM has is power consumption. This is why Nvidia went with TSMC 7NM for its GA100 compute GPU.
 
Review here that shows the all important min FPS / lowest 1% FPS (most dont bother):
https://www.kitguru.net/components/...ss/nvidia-rtx-3080-founders-edition-review/7/

The rtx 3080 handled every game at 4k (rtx off), with 50 fps or more. Except for Troy TW running on dx 11. Unfortunately, the developers abandoned dx 12 (used in tw: warhammer 1+2). Nvm, Troy is a pretty average game anyway, imo.

Its performs very well, but not what id call affordable...

What are peoples predictions on where 6900XT will land performance wise?

I think 2080ti +20-30% is what they would be aiming for when they said they wanted to be competitive with Nvidia's 3000 series. It's was pretty standard increase pre-Turing. So I can see them being competitive with the 3080, whilst being maybe £50 less.

If Nvidia had knocked it out of the park, I would have been less hopeful.

28bn / 628mm2 = 44.6m
15.4bn / 360mm2 = 42.8m

Without knowing the exact size that looks about right but we can't assume RDNA2 GPU's are built on the same 7nm node, i don't know how many 7nm Nodes TSMC have but its a few.

Navi 10 is built on the original 7nm, it has 10.3bn transistors and its 251mm2.

10.3bn / 251mm2 = 41.35m.

Look at that, close enough, i think we know the Series X is built of TSMC's original 7nm.

I think, if i remember rightly, according to Moore's Law Is Dead. The 7nm node RDNA2 is earmarked for has a density of over 69m / mm2

yeah I think AMD will be looking and going you know what, if we can now get Big Navi minimum between 2080TI and 3080TI and release at £599 they have a serious contender!

Yup - esp if they can keep it under 300watts as well.

Only 100% :D:D:D:D

Thats a massive gap to bridge, especially on same node.

It is, but surely AMD have been aiming to beat the previous gen best card (2080ti) with their new gen top tier card (6900 or whatever), it would be a massive fail to be behind the 2080ti this gen. So something better than the 2080ti, whether its 25~30% better like the 3080 or less just needs to be priced right to attract attention.
