Anyone planning to buy the RX 6900 XT, rather than RTX 3080?

interesting graphs, others have shown transient spikes nearing rtx3090 levels and their psu hitting over current protection limits with amd's recommended 850w spec
we're at the point where reporting average or a peak from afterburner isnt enough - using those tpu graphs you'd be forgiven for thinking you can get away with a 650w psu

knowing asus, their 6900xt strix lc will cost as much as an rtx3090 so pick your poison

When you say 'others' you actually mean just Jay2cents who claims his psu hit current protection and we all know he's almost as big a shill as you. Funny how his 3090 never hit protection limits eh.
Nearly all other reviewers state the gpu power draw is less than 350W. I get that you are so far up Nvidia that it is hard for you to do anything other than troll AMD threads but please stop with the fake news rubbish.

I already posted that for the 6800xt AMD got 9% and custom water cooled got 1% more. The 6900xt is designed to have better performance within the same power budget as the 6800xt. So its expected that the 6800xt max oc will be faster than the 6900xt max oc.

For custom AIB cards power limits, cooling and bios are going to change and the 6900 XTs will have no problem beating their 6800 XT counterparts.

Even as it stands like for like a refence 6800 XT can not beat a reference 6900 XT when both are at stock or overclocked.

The custom watercooled 6800xt https://tpucdn.com/review/asus-radeon-rx-6800-xt-strix-oc-lc-liquid-cooled/images/power-maximum.png (yes thats 380watts) had 9% more performance with a max'ed out power limit, when compared to the stock 6800xt when OC'ed its 4-5% more. On custom cards you can get upto 9% more performance, making the water cooling return very little extra performance. Both the 6800xt and 6900xt have the same power limits. Thus you need to undervolt the 6900xt. Custom 6800xt overclocked are faster than the AMD 6900xt overclocked.

6800xt watercooled, performance 109% 380 watts https://www.guru3d.com/articles_pages/asus_radeon_rx_6800_xt_strix_oc_liquid_cooled_review,32.html
AMD 6800xt tomshardware, https://cdn.mos.cms.futurecdn.net/6iumpK8NoYBd8NjWXh9iX3-970-80.png.webp You can see that you get very little extra power to the card between the AMD version and the watercooled asus version. AMD 6800 XT OC starts off at nearly 360W in FurMark before it throttles down a bit and ends up at closer to 350W. So the higher power limit is 380 watts; 40 or so watts more. Nets about 4% extra performance over a AMD 6800xt overclocked. Next to nothing if you compare to another custom 6800xt. The RTX 3080 on water is almost a 3090 FE stock in raster games. With an increase to 450 watts (from 320 watts) for its power limit. Asus RTX 3080 strix rog gaming oc can hit 2.19GHz on water. With over 20k in time spy.

Lol there is only one 3080 in TimeSpy better than the 6800xt and i suspect it is on LN2. The 6800xt is alreaady a better card in timespy average score, is like 50 points ahead right now and the gap will grow bigger.
6800xt is a much better card than 3080. The AIB 6800xt models are much better than the 3080s.
The 6900xt reference is not that great but once the AIB models will become available, we will see some of them beating the 3090's. Even at 4k.

Similar performance level in most games. Which do you prefer and why?

I'm planning to get the 6900XT but once the performance issues are fixed. I can't justify the price of the RTX3090 however £900 for near to RTX3090 performance I can live with.

Also overclocking wont create a version of DLSS any time soon

Anyone interested in the prospect of buying an AMD card obviously doesn't care about RTX, and if you don't have RTX enabled then there's no point using DLSS over decent AA.

You are going round in circles.

The bottom line is the Watercooled 6800 XT Strix is faster than a reference 6900 XT. Using that as a bases a 6900 XT Strix version using water will be even better and could give the RTX 3090s a very hard time.

Please don't post any more walls of links to reviews etc as they irrelevant to the basic point, - an AIB partner 6800XT using water is faster than the reference 6900XT.

4% performance is not worth watercooling, zero performance increase if you count custom cards with the same power limits which are not that much higher than AMD cards. You get more performance from a ryzen 5000 series cpu and SAM. Water cooling a 6800xt is not worth it. The 6900xt will be the same.

Water cooling works for the 6800 XT, the Strix LC beats the reference 6900 XT.

Water cooled 6900xt will beat the 3090 easily.

Remember the Red Devil had a 3rd power slot on the PCB. So maybe we will see a Liquid Devil 6900xt with 3 power connectors and unlocked power limit.

Although then if the 3080Ti does materialise and is pretty much 3090 performance at close to 6900XT price...

Easily? What by a couple of fps? That you can measure but would never 'feel'.

Water cooled 6900xt will beat the 3090 in SoTTR, dirt 5 and Godfall - games no one plays and then lose by 50-70% to Nvidia in games people play like Cyberpunk

I agree with you for once

Seems to depend on the game, TR or Valhalla the AMD's do very well. Other games, they get trounced.

Still, watercooling the AMD cards seems to be the best bet.

of course there is.
some games are already struggling to hit constant 60fps with these new cards at 4K and what about 4K high refresh rate gaming.?
I will take any extra performance I can get at 4K...

This graph is just stupid.
Comparing AMD cards overclocked as far as they can be to stock Nvidia cards.
I do like HU a lot but stuff like that is done for AMD funboys only...
Although having said that they probably do it the other way around too.

The review is about the 6800XT, not overclocking in general. It doesn't mean that the Nvidia cards cannot be overclocked but simply showing that the 6800XT can achieve a certain level of extra performance when overclocked.

Kaapstad · 10 Dec 2020 at 15:45

Looks like the AIB partners mean business with their cards check out the specs of this one.

3 x 8 pins power leads, 480W power limit and a 900W PSU recommendation.

Nice cherry pick. Now turn on RT and DLSS, for well over 100FPS on an overclocked 3090. With no way for the 6900xt matching the performance. Not that it can anyway. Note that its faster than a 3090 when the 6900xt is overclocked and can beat a 3090 by your statement. Yet the overclocked watercooled 6900xt cant match a 3090 in a game were ryzen 5000 series with SAM and 6900xt have a performance lead in raster. Note you can overclock the rtx 3080 to near enough 3090 speeds.

With the 6800xt watercooling does not increase performance by much. This is what the data shows. 4% more performance is not worth expense over an AND 6800xt. But custom 6800xt get approx. 9% increased performance and the water cooled card upto 10%. So for all that watercooling you get 1% maybe at best extra performance. Also both the Nvidia 3090/3080 overclock well on air that watercooling is more likely not worth it as well.

Cant match a rtx 3080 with RT on and no DLSS. With DLSS its a joke and there is no amount of overclocking that will fix it. https://www.tweaktown.com/reviews/9...x-3080-oc-edition/index.html#Benchmarks-1080p The faster 3080's get within a few fps of the 3090, like the Asus strix rog 3080 gaming oc. RTX 3080 FE OC gets top above stock 3090's. RT and DLSS show in graph.

Turning on DLSS the lead would be massive https://www.guru3d.com/articles-pages/geforce-rtx-3080-founder-review,17.html. Let just OC the 3090 and compare to a good 3080 https://www.tweaktown.com/reviews/9614/asus-rog-strix-geforce-rtx-3080-oc-edition/index.html.

Note how just SAM and an AMD Ryzen 5000 series cpu provides more performance. Note how the RTX 3090 with a 480watt power limit destroys all before it, with or without DLSS. Thats before overclocking. Decent RTX 3080 out performs the 6900xt @ 4k. 101fps on a 8700k 5GHz.

I have just run cbyerpunk 2077 and know why the 6800xt and 6900xt wont support RT fo awhile. They cant without a DLSS like feature as performance would be too low.

Looks like the 6900xt is like the RTX 3090, just not worth the money.
