    It sounds like a movie trailer; but the trilogy ends today, the 3rd iteration SKU of AMD Big Navi gets reviewed, oh yeah the shader unlocked megalodon is going to battle the GeForce RTX 3090, whilst b...

    6900XT is just slightly better than the 6800XT, it feels more like an overclocked 6800XT (especially when looking at the RT Performance).
    Those Benchmark results was kind of expected to be honest, because they both were introduced to have the same TDP, turns out the 6900XT drains (slightly) more than 6800XT :rolleyes:

    Since Nvidia basically confirmed that the availability issue is going to remain like nowadays for several months, perhaps even longer then half a year, I bet the situation for AMD must be even worse then. Especially considering the fact that 6800XT still isn't nowhere to be found at all, let alone what will be with the 6900XT.

    Thanks for the review, does what I expected

    It's what 3090 did to 3080, hundreds of dollars more for almost no improvement in performance

    I'd rather buy 6800XT and watercool + OC .. for example Asus 6800XT LC beats the 6900XT (Techpowerup Review)

    Really worried about availability tho - This could be a halo product .. Oh well could not care less, not buying. It's 3080 Ti or nothing till 4000 series hit in 2022.

    Might consider AMD by then, if Ray Tracing has improved and they have a DLSS-alternative.

    Good to see that 6900XT beats 3060 Ti slightly in Ray Tracing tho :p

    I am disappointed by the limited gap in performance between the 6800, 6800xt and the 6900xt. Its almost justifiable not to have the 6900xt exist.

    A bit underwhelming for a flagship, but, a giant leap compared to what AMD offered in the past 6 years.
    Not sure how their Windows drivers are failing so badly with compute loads, or OpenGL. At least when it came to the 6800XT, the Linux compute performance was crazy fast, whereas in Windows it's downright slow.

    The performance gap between 6800 and 6800XT is 15% on average.

    Thats alot in my book... As expected

    6900XT is only 6% better than 6800XT on average tho..

    meh

    999
    matches or slightly beats 3080 at 4K
    has no dlss and poor RT performance for a card that costs this much
    it's a good card on its own but compared to 3080 at 699 no way it's worth $300 more.

    it's a weird strategy by amd to push this as a titan-esque card at 999.

    Sure...now what the performance gap between the 6800 and 6900xt?

    I have went looked over some other sites results and the 6900xt faired better during their testing? On average, beating out the 3090 at 1440p, exceptionally different results

    If there is AIB which is able to equip any 6800/6900 cards with faster memories, those will sell like hot cakes.

    Well for the measly price of 600€ more in Finland then 6800xt this is a no go :D

    how ? never heard of gddr6 go beyond 16gbps unless we're talking oc
    this card should absolutely be 12g 384-bit unless amd like losing to nvidia's 699 card in every other title at 4K

    Ray Tracing may become more important as time carries on. I suspect more developers may spend less time programming in dynamic lighting and proper shadows if they can just use RT. At this point the value in the 3080 is paramount if you want RT...I am still impressed by the 6800 and 6800xt

    I participated in the "swiss etailer lottery" you might have read about on videocardz (if not they were honest as usual and told everyone they would only get 35 cards so they made a lottery rather than frustrate buyers who think everyone else is getting a card except them)
    because of the non-availability of everything I leave my purchase decision to chance.
    That said strong chances I'll leave it to the second in line if I win because what I really want is a >10Gb 3080 I do use nvenc and that's a huge plus for me

    EDIT 1 : nvm I for sure will leave it to someone else it's 1293$ for a reference card ! (the ek asus watercooling model of 3080 10gb is 1058$ the asus tuf 921$)
    EDIT 2 : I guess I'll wait for the 3080ti as long as it has 11-12gb or more I'll be ok I've already seen games taking 9+Gbs with rivatuner on-screen stats 10gb is just no)

    I don't think the question is wheter but when.there's no other way we can see movie-like games one day.
    sadly,sloppy devs are more interested in doing half assed job with rt and dlss and just slap "rtx on" on the box to sell more.
    that's why we're seeing rt develop slowly.not enough games like control,minecraft,cp2077

    Great review and conclusion Hilbert. 6900XT and 6800XT are great raster GPUs but the price difference for so little more RT performance makes it a huge question mark...

    Most AMD bois apparently does not care about RT and AI UPSCALING like DLSS (with 100% perf boost and even IQ boost with proper implementation).

    RT + DLSS used in combination allows for RT without perf hit and looks insane - Wait till people see Cyberpunk in full RT glory. The OFF images looks DULL in comparison.

    AMD should have priced 6800 at 449, 6800XT at 599 and this 6900XT at 749 tops.

    BUT they knew supply was LIMITED and pretty much ZERO - Which is why prices are high.

    3080 at 699 will easily outsell both 6800XT and 6900XT.

    Then you are out of loop for a year. But that's difference between official and background information.
    Samsung officially states that even now, they are sampling 16Gb GDDR6 with 16Gbps. And that they only have in mass production 16Gb GDDR6 with 14Gbps.

    Problem as always is cost vs demand.

    DLSS doesn't give an IQ boost over native - it sometimes clarifies text but everything else is definitely still worse and in motion there are noticeable artifacts. It's a great technology and I hope it improves but it has issues. Also most of the earlier reviews say the RT implementation in Cyberpunk isn't great - the reflections are way too much and performance crashes in a bunch of areas even with DLSS.

    FTFY :p

    but yeah,with turing nvidia knew that RT isn't even remotely possible without DLSS,and now even a 3080 will struggle not to drop a frame below 60 here and there if you don't use DLSS along with RT.
    I'm kinda like :rolleyes: when I hear ppl say amd is coming up with an answer to dlss soon to make rt playable
    as if they hadn't known that you need it for RT since Turing came out.
