4k 6800xt gets almost a 8% spanking by 3080rtx

6900xt might just squeek past 3080 at 4k

with a 10% uplift over 6800xt.....

whats that average in frames ? also whats the average in 1440p

Thanks

I think the 6900xt will follow the same pattern in performance: great at 1080p and 1440p and a huge drop at 4k. There is nothing new in that card to make it behave different and there are no new drivers.
AMD only have one chance: to bring as many cards as they can for sale, faster than Nvidia. And it looks like that isn't the case. They had a lot of time to prepare this launch but they missed the opportunity. Not to mention that the RT performance is below what most of the gamers interested in RT need and they don't have an equivalent to DLSS to make some of the games playable.

Sure maybe in 3 or 6 months or a year the 6800xt or the 6900xt will beat their Nvidia opponents even at 4k, or they will bring DLSS and bring better RT performance but by that time, most of the people willing to pay more than $600-$1000 for a video card will already have Nvidia cards in their systems.

The 3080Ti will still sell. I think it will beat the 6900xt in 4K (at least for a while) and it will offer far better RT performance.

I wouldnt exactly call it huge drop off at 4K can you give me average over like 20 games ? also its AMD's first attempt into RT its Nvidia's 2nd I personally think its impressive how much ground they have made up the real test will be the next cards after these

Did you intend to look stupid?

denial is the first stage. work through it bro.

these are average results. From 12 different review sites, across probably 30-50 games.

you are not going to get a better and more fair way of judging the cards. to check the actual fps you need to look at each review site independently.

Its also 8% cheaper (FE vs reference).


3080 = 90% of a 3090. There isn't really a lot of room in there for a 3080 Ti. Will it be a 3090 with less ram, or a 3080 with more ram? Either way its not going to be more than 10% faster than the 3080 because that makes the 3090 redundant?

6800XT slightly behind 3080 at 4k and slightly cheaper, 6900XT likely to be in front of it and more expensive. Be interesting to see if 6900XT gets close to or even beats the 3090 in 4K at two thirds the price.

AMD have flanked Nvidia's cards.

Unfortunately once NVIDIA releases 3080 Ti the 6900XT would be a rather hard sell. Firstly when you have so much cash to burn on 1 GPU these cards should be aimed at 4K 120hz. 3080 and 6800XT turned out competitive at 1440p and 1080p when AMD’s marketing compared both cards with SAM and rage disabled. But 3080 pulled ahead by 7.4% at 4K. The 3090 is about 13% faster than 3080 at 4K. AMD turned on Rage and Sam while comparing the 6900XT to 3090 indicating it won’t be all that competitive without them.

So even with the absence of the 3080 Ti, its hard to justify why you would pay £300 more than a 3080 for roughly 10% rasterisation boost at 4K over a 3080 but with RTX performance below that of a 3070 and no DLSS at the moment.

I think the 3080 Ti would be a killer GPU once it release at £999.

What 300 more? Perhaps u didn't look at current 3080 prices (for example on here)

I am not a fan of Nvidia. But i see a huge drop on both Radeon cards at 4k. There is no reason to not keep the same lead at 4K as they have at 1080 and 1440p, they have faster frequencies than Nvidia and more Vram. But if you check the benchmarks you will see them both dropping a lot more FPS at 4k than their Nvidia opponents.
Even when the reviews are favorable to them, like the HU review. You can notice the huge drop every time. Look at AC Valhalla, that`s a huge drop in performance. In 1440p both cards are ahead the 3080 and even the 3090.
Again i am not a Nvidia fan. I wish AMD could do better but i am afraid they missed a huge opportunity here.

They have too little memory bandwidth cause amd cheaped out a bit by using lastbgen g6- 3090 has nearly double the bandwidth compared to big Navi. If you think the performance drop off is big at 4k, just wait till you see 8k. Noticed how Nvidia paid special attention to advertising the 3090 as 8k capable and AMD is totally dodging any mention of 8k, it wants no part of being compared to the 3090 at 8k cause it will be a slaughter

3080FE = £649
6800XT = £600

you are right its 8% more expensive.

but wrong about 6900xt . its clocked the same as 6800xt and has just 8 more compute units.
That will give it theriotical maximum 11% lead over 6800xt

which will put it a best, only 3% quicker than 3080 @ 4K on that graph.
IT will however decimate 3080 and 3090 probably at 1440p.

You have to prove there is something wrong. It does not matter what happened and when it happened in the past. Each argument must be considered on its own merits. The only standard is if an argument meets burden of proof.

RT performance for example does not benefit much from overclocking. The rest is a good question, next week the AIO 6800xt's come out so this could change. No they cant reach 2.65GHz easy, most reviews hit 2.4-2.5GHz under load. The fastest air cooled 6800xt on HWBOT has a 2.65GHz boost but the clock speed is much lower under load because of the power limit. They also hit 90c+ at 2.4GHz. If we overclock the 6800xt you get 4% more performance.

Time Spy. 6800xt OC 18304 The card was stable with 2500 or 2600MHz dialled in, but actual frequency diminished slightly as I pushed passed 2400MHz. https://www.kitguru.net/components/graphic-cards/dominic-moass/amd-rx-6800-xt-review/32/ 10900k 5.1GHz



Time Spy RTX 3080 factory OC 1935MHz 8700k 5GHz (The RTX 3080 hits a lot higher than this on a good card, with water reaching up to 2.2GHz) score 18306 https://www.tweaktown.com/reviews/9...-3080-oc-edition/index.html#Test-System-Specs

I played with my friends 6800XT to set up OC, it was 76 degrees on auto clocks and we got 2605MHZ first then 2654MHz the day after. From a ref card

 

[Dontrocktheboat]

6900xt at £915 performance estimate.
less than 4% over 3080

yeah i think 3090 has not much to worry about 4k+

Lets see on 8DEC

 

[Besty]

re: Overclock on 6800XT I think the problem is two fold:

a) the power limit is +15% no matter what you do

b) the memory clock is also locked to a low number.

which means that even if you get to 2.6ghz you won’t see a nice linear scaling at 1440p.

This is all designed to keep the 6900XT out in front, it will be very interesting to see if these limits are removed on the 6900XT.

slap some HBM2 on that puppy AMD for goodness sake.

It won't work - HBM is very expensive - Navi 21 is fast because it has that >2000GB/s Infinity Cache.
AMD tried with HBM but it proved a worse solution.

Your remark is wrong.

But yes, if AMD has access to faster GDDR6 - it would have been better.

Ok mate I been looking through quite a few youtube uploads i dont see much in it 6800xt wins at 1440p and loses slightly at 4K

one of them was Hardware unboxed watched other reviews and all same pattern

1440 over 18 games
6800xt min 123fps Max 157fps
3080 min 122fps Max 153fps

4K
6800xt min 79fps Max 93fps
3080 min 81fps Max 98fps

wouldnt exactly call that a spanking I myself play at 1440p still think AMD is behind but made really big leap from last gen still need to sort out its own DLSS and lower RT which is expected because its 1st attempt at it and nvidia had headstart on that, also how the drivers overtime improved a lot on the 5700xt wont be surprised if AMD does the same again

Infinity cache at 4K and 256-bit bus. Designed for consoles....

Still on the troll I love how not even 8% is supposedly a "spanking". Maybe in lala land where you seem to live.

Yeah they'll just go right out and slap hbm on the core like that's how it works.

Dont think there is a faster GDDR6?

that's GDDR6X and its developed with nvidia. AMD aint getting that.

just a 8CU uplift over 6800xt aint going to cut it.

512-bit bus then, sorted. thats what it needs, maybe it has it???
8% is not bad.
Considering 6900xt will be beating 3080 @ 4k for about 3-4% for £extra 300 notes......

That's some people's job - some of them are even lucky to get paid by certain companies.

Except in that game and settings used 3090 is slower than 2080ti so clearly there is a driver issue.
