AMD were cherry picking hard

7900XTX barely 50% faster across Techspot / HUB, Computer Base and TPU (with their new 13900K test rig) than the 6900XT let alone the 6950XT. Suggests to me that if you were to limit the 7900XTX to 300W the performance difference is barely anything.

7900XT being on par with the 3090Ti is also pretty poor. Was expecting this to be near the 4080 with the 7900XTX comfortably between the 2 of them.

Still TPU with their updated RT suite are showing that the 7900XTX is faster than the 3090Ti in RT on average and is better perf/$ than the 4080 even in RT. Performance is about 86% of the 4080.

Are you crazy? 3090 Ti is a very powerful GPU, pairing a 7900XT with a 5800X3D will have you set for the next 5 years.

Given the numbers AMD shared in the announcement and subsequent PR bits n pieces I expected better. I expected the 7900XT to be around 95% of the 4080 with the 7900XTX sitting right between the 4080 and the 4090.

That the 7900XTX barely clears the 4080 (although great to see the 7900XTX not losing any ground at 4K like the 6950 used to) and the 7900XT is a step down it is not great.

Further from a generational point of view the 7900XT is only 23% faster than the 6900XT. If the 7800XT is just 30% faster than the 6800XT then the 7800XT will basically match the 7900XT. I mean I thought the performance gap between 7800XT and 7900XT might be close but I did not think it would be that close. Also a 30% gen on gen gain is pretty much bottom of the barrel and is only really acceptable if pricing stays the same or broadly similar.

7900XT has over 2x the transistors and is made on a miles better node than Samsung 8nm.

Navi 31 is ~35% faster than Navi 21, which is close to the uplift from Pascal to Turing, despite the latter uplift being done on the same node and adding RT hardware.

Needless to say, we expected much more..

AMD optimized game indeed.
This game first design for PS5 than ported to PC. It is using Async computing as well.

It really shows how much Nvidia has invested in hardware and pushed them self that they do not repeat another kepler hardware.

From Maxell Nvidia is different company.

Ampere is better than RDNA 3 fact.

The real reason Ampere fell some short was due to Samsung die's and if Nvidia used same 7nm of AMD than AMD would have been nearly competing Nvidia last gen.

Ampere is massive achievement of nvidia in hardware level.

EDIT: For reference.

This is the kind of chart I expected as an average. 7900XT fighting with the 4080 and the XTX sitting in that huge gap between the 4080 and the 4090.

RT performance is about where I expected it being around 85% give or take of the 4080 but the raster is about 10% shy of where AMD indicated it would be.

Based on the TPU 4K data, relative to the 3080 10GB.
7900 XTX is 51.5% faster
4090 is 84.8% faster
Or for a stupid metric that matters only to people with RTX 3080 10GBs like me, the 7900XTX is 0.0515% faster per dollar while the RTX 4090 is 0.053% faster per dollar.

So it should be $900 for me to prefer it. In the end, much worse performance than I had expected. I expected 1.6x my RTX 3080 at least.

XTX is about the same as the 4080 but has some issues - the expected lower RT performance, but also the infinity cache means it behaves like a card with too little memory (performance and 1% mins fall off in a similar way to cards that are starting to run out of memory). If they'd doubled the infinity cache so it wasn't struggling at 4k it would have been much stronger, which being as it's on chiplets should have been easy!

Still there are no bad cards, just bad prices, if they drop the price a bit then it's not such a bad buy. XT needs to drop more.

I am wondering if the best case scenario provided by AMD was for ray tracing if using a Ryzen 7000 as test bench.
Techspot used a Ryzen 7 5800X3D as test bench, Guru3D used a Ryzen 9 5950X, PCMag used a i7-12900K
The jump in RT is higher than the jump in raster, so maybe the "up to" is coming from this one.

Personally, I wanted the jump in raster to be higher, but AMD balanced it out.
Enough for 4k fluid gaming in raster, mush stronger RT than previous Radeon gen.

Yikes. I had tempered my expectations, but didn't think AMD would sail underneath them still. It definitely puts a damper on my original plan to get a 7900XTX at launch. Clearly there's an issue in the GCD and perhaps with the drivers as well (it should not be spending 100W idling for multi-monitors). It really does seem like AMD bit off more than they could chew here. I'll sit this out for a few months until some of this stuff is sorted and then reevaluate. I really do hope they get a respin out in 6 months rather than 12.
