Its different again
For the first time i think all of these now match up in their architecture...
This is the 20 Dual CU one. (2560 Shaders) (6700XT)
40 Dual CU (5120Shaders) 6900XT
The XBox Series X. 28 Dual CU (3328 Shaders) 6800XT

Yes that's enough.
What i can't see on any of these slides is that large L4 Infinity Cache. Including the XBox Slide which we know is right.
Take the 6700XT, AMD have said there will be, i think they said double digits IPC gain in RDNA2 vs RDNA1.
Lets say 10%
Clocks of 2250Mhz. (+18% vs 5700XT)
That's +28%
I think the 6700XT will trade blows with the 2080TI.

Enjoy the console and £80 per game lolz
If we go by your assumptions then 28% over 5700XT would bring it to 2080S levels at 4K, not 2080Ti. If we then assume the typical AMD ~15% - 20% performance increase between SKUs (at best). Then 6800XT would be slightly slower than 2080Ti level and 6900XT would be slightly slower than 3080 (~15% - 5% slower). I am not claiming this is the case, just correcting your own assumptions.
5600XT to 5700 performance increase at 4K = ~16%
5700 to 5700XT performance increase at 4K = ~13%

At 4K sure.
That's like Digital Foundry saying the 3080 is 114% faster than the 2080S in Doom Eternal, its like that only in 4K because at 4K the 2080S chokes while the 3080 doesn't.
I'm not disagreeing with what you said, its just that you're using a measure where the 5700XT is out of its depth.
I'm going off 1440P numbers because the 5700XT struggles at 4K, its not a 4K card.
From TechSpot (Hardware Unboxed) there is no CPU bottleneck in these...
2080S: 121 / 104 = 1.163 (+16.3%)
2080TI: 141 / 104 = 1.355 (+35.5%)

I will thanks. I've got game pass so have no intention of buying any new game that isn't on that though. I only get about 2 or 3 games outside of game pass in a year, and then its either cheap 2nd hand or when they are on sale or trade in so I dont think I've ever paid full price for a game on console
If you wait a couple/few months after launch then console game prices always drop way down. I never buy launch games for full price unless it's something exceptional.
The metrics don't change much and the 6700XT would still be slower than a 2080Ti because the 6X00 range are being marketed as 4K cards.
5700 to 5700XT shows a pathetic ~13% performance increase. If AMD 6X00 SKUs follow the same metrics and your 28% faster than 5700XT assumption, then:
6700XT slightly faster than 2080 S
6800XT with 13% extra performance would be slightly slower than 2080Ti (trading blows at best)
6900XT would be right between 2080Ti and 3080
This is going by existing metrics that show AMD typically have ~12-16% performance uplift between SKUs. If that is what 6900XT offers with 16GB I would be very happy at the rumoured prices.

Or wait until they are on sale used, or trade with a friend.

i think the clock speeds will be slower and the 6900XT will be bang on 3080 speed.
The 5700 has 36 CU's (2304 Shaders) compared with 40 CU's (2560 Shaders) of the 5700XT +11%, Its also about 100Mhz lower clocked, about 5%, that's a scaling of your 13% for 16% more GPU
Agreed, just about.
28% more GPU vs a card that is 16% faster, its a bit more than slightly. After scaling its 9/10% faster, 90% a 2080TI.
where did you get 13% from?
The 6800XT has 30% more shaders than the 6700XT, add that minus scaling (25%) to the 6800XT, now you're at 115% a 2080TI.
Ok you're not looking at the differences between these GPU's.
6800XT: 52 CU's
6900XT: 80 CU's
80 / 52 = 1.538 (+53.8%) 45% after scaling? Now were at 160% a 2080TI, the 3080 is 32% faster than the 2080TI, 132%.

But the 5700XT isn't a 4K gaming card. And by extension the 6000 series successor also won't be a 4K gaming card. So, staying at 1440p where the 5700XT is pitched, I'd say humbug's numbers were a little conservative. I can see the 5700XT successor surpassing the 2080 Ti, and by extension beating the 3070.
If you want me to stop being conservative i'll just come right out and say what the numbers suggest. The 6900XT is easily an RTX 3090 killer.
There, i said it
I'm not saying this is what we will see, we are all just speculating on rumours here. Its what this thread is for.

those of us not obsessed with worshipping the Leather Jacket know what the numbers could mean
