AMD Navi 23 ‘NVIDIA Killer’ GPU Rumored to Support Hardware Ray Tracing, Coming Next Year

If the 6800xt is a 72cu card competing with a 3080. How does 8 more CUs get you 3090 performance at 4k?? And how are they able to bump the gpu clock higher with more CUs??

That part isn't adding up to me. And if it's true that it takes a 2.5 slot, 3 fan solution to cool it i doubt its just 72CUs.

I'm beginning to think that the 6800xt is 80CU card. The 6900xt has something higher like 96CUs or something. Don't get me wrong if it is 72CUs that quite impressive to compete against a 3080. But im very skeptical thats the case at its rated TBP, allegedly.

Howcome the 3950/5950x has the highest core count and highest clock speed in AMD CPUs? It comes down to much headroom there is in binning the dies - if the 6900xt has more cores and it's clocking higher than the 6800xt it probably means that the architecture and 7nm process node has more to give - AMD could make an even bigger GPU if they wanted to

I would assume that the OC potential of the 6800xtvwould also be bumped up for that very reason.
 
If the unverified information is worth the pixels it means AMD themselves will be parcelling out the supposed 6900XT reference models at launch.

The memo would suggest they would be more paranoid than most in weeding out the card scalpers which I'm sure would be welcome specifically for the much more limited halo card.

Unless what it actually means is the card will be sold as "AMD" brand as opposed to Sapphire or whatever else AIB. In which case down to the retailers again.
 
So were thinking what was shown was not Big Navi afterall, like a lot of us already predicted..

What if its the 72cu variant, and the drivers have eeked out more performance since.. Prices will be key here.

However if its true at the 6900 model is AMD only, if its £800 or less im buying, not that i think it will be, but if it is, im in!
 
I'm really looking forward to this generation of AMD cards, I've got a 3080 pre-order but if AMD can come up with something with similar performance at reasonable cost and availability then I'm in.
Currently running a 1070 and need an upgrade capable of running the reverb G2 I have on pre-order.
 
RX6900XT in limited quantities?? I hope not too limited as that's the card I'm pretty sure I want. I guess if it's priced high enough they'll only need to produce a limited number but I really hope they
price it competitively (under 1K) and make plenty of them.

Makes sense

so the card shown and benched on 8 October and seems like it's going to be at or little bit under 3080 level is the 6800xt

which makes the 6900xt the 3090 competitor - given how close in core count the 6800xt and 6900xt is the 6900xt is likely to be about the same level as the 3090, maybe faster if it can clock higher than the 6800xt

Am thinking this too, under the £800 mark would convert quite a few would be 3080 buyers over to this. It's about the price I think the 3090 should have been based on performance uplift.

Seems like a big gap between RX6800 and RX6700XT if true (64>40 compute units) - room for another card in there at least, although it would have to be a RX6800XL or RX6700XTX

True however putting other cards into that doesn't make too much sense when you think about the dies, N21 full die is 80CU, N22 is 40 N23 seems to be 32. AMD rarely cut down dies into lots of different versions, its usually at most a 10% cut down version, otherwise you're now wasting a lot of die space etc. So it's more likely to be something like this, going by what others on Twitter have suggested:
N21XTX = 6900XT - 80CU
N21XT = 6900 - 72CU
N21XL = 6800XT - 72CU
Then N22:
N22 Full Die = 6800 - 40CU
N22 Cut V1 = 6700XT - 36CU
N22 Cut V2 = 6700 - 36CU
Then N23:
N23 Full Die = 6600XT - 32CU
Then further down until however many till N24 has, where no on knows how manu CUs it has yet.

If the card shown in their presentation was the '6800xt' then that is something to get a we bit excited about. Not sure the full fat navi will surpass the 3090 but it may just be nipping at its heels.
