that demo is a Microsoft DXR ark benchmark, I'm pretty sure Microsoft did not design direct x12 ultimate to favour Nvidia when it would benefit their own Xbox to favour AMD

I'll give you one better. I run the same demo on my 2070S and got wild results just by moving other windows around, or for example clicking the window and making it active (144FPS) VS clicking on empty desktop to make it inactive (342FPS) - the latter gave me considerably higher FPS for no reason at all! In other words, that benchmark gives horribly inaccurate results and I wouldn't use it for any sensible comparison at all.

@Grim5
More proof, ignore it.

11:30 3080 vs 6800XT (bottom of graph shows no rage mode or SMART)
12:57 6800XT Rage Mode + SMART access improvement
19:52 6800 vs 2080ti (bottom of graph shows SMART)
22:44 6900 vs 3090 (bottom of graph shows SMART and rage mode)

So really the 6900 is only around 5% faster than the 6800XT when rage mode/SMART is not enabled and is 50% higher price?

It appears you need smart access memory which is available on Ryzen 5000 series CPUs to get optimal performance.

It's very possible that for gaming you won't need top notch ram.

It will be interesting to see how it pans out.

Never going to happen. NV have always been behind on nm sizes.

Don't think it matters, both AMD and NV have got orders with TSMC for 5nm products in 2021/2022.

especially with the lower power requirements

This is the first thing big spenders look for.

chrcoluk · 28 Oct 2020 at 23:38

smart access memory sounds like it bypasses uses ram as an intermediate buffer?

To be fair if you aren't paying attention their slides were a mess in that regard - the 6800 slides had just Smart enabled, no power draw. The 6800XT had power draw but neither Smart nor Rage, the 6900XT had both smart and rage but no power draw.

3 slides, 3 different formats. No consistency for comparisons.

Like I say I think they had to enable both for the 6900XT because otherwise it would have shown tiny improvements over the 6800XT and made it look more daft.... a little more consistency between slides would have been appreciated though imo.

That said the 6800XT is where a lot of the attention is going to be focused and that is the one were it really was as apples to apples as a presentation slide is going to get with no boost from smart or rage and a power figure for comparison.

Its not just about big spenders. Some of us have ITX rigs where putting a bigger PSU could be a problem, so not having to worry about needing to do that is a nice touch

Tbf I wasn't posting a sarcy comment to you or ITX owners

buildzoid speculated it might be a locked out feature on some cards, he said he remembered in some previous AMD cards where raw performance was close, the higher end cards had more o/c features unlocked.

@Gregster are you going full AMD? Ryzen 5000 + 6900XT?

Funds are tight at the mo but my 6850K is a dog for clocking, so possibly will do in the future.

Joxeon · 28 Oct 2020 at 23:43

One things for sure that AMD are back in the high end GPU market but now they need to ace their driver and deliver stock.

Isn't the 3090 nearly triple the 3080 price for the 10% gains?

But I would expect it to be about that, yes. The top tier cards this year really just aren't worth it.

Lies!!!

At most you will buy it and then find a reason to sell it and buy an nvidia card!

Haha, it wouldn't be the first time but the 3090 is out of my price range this time but the 6900 fits my wallet nicely. No rush either, as I want to hold my 2080Ti for a bit but will see how my patience/patients hold out

Yes, I think if they showed the powerdraw in those slides, it wouldn't look so favourable. I also notice how all the fps comparisons say "up to" instead of the expected average.

Cool, its looking like AMD's going to take the Gaming crown in CPU's with Ryzen 5000.

They need to now else reviewers will test the new GPUs with intel CPUs if they don't and they wont get the extra perf bump.

No xfire which was to be expected, however prices as expected and fantastic performance, all as expected as far as I see! Plus some lovely additional bonuses for you guys who will move to Zen3, great stuff
