all this RT talk will be interesting to see GodFall being optimized for AMD

This is the thing, AMD RT performance is not as good as Nvidia's in most existing games, sometimes its outright bad, but lets not forget Nvidia has a head start on AMD, these games are optimized for Nvidia, so far from what we have seen where optimized for AMD it turns the tables and blows Nvidia in to the weeds, Dirt 5 AMD RT performance is 35% better than Nvidia.

I would surmise its not a problem with the hardware, AMD's hardware is just as good as Nvidia's, it just depends on who its optimized for. Nothing new about that.

oh the excuse for Dirt 5 its because Ray Tracing is only used on few things, with Godfall having bigger environment will be interesting
 
AMD really need to get their DLSS alternative out there as soon as they can though. It's really crippling their RT performance without it.

It would be like Nvidia cards without DLSS, RT would become a feature you couldn't enable at 4k because games with RT would become unplayable. At least you can enable DLSS and bring the frame rates up to playable levels. Unfortunately you can't do that yet on AMD.

Yeah :) well this reasoning.... Green or Red they are both rendering the same image, this argument that its better on AMD because its only doing this or that..... AMD and Nvidia are doing the same thing and one does it much better, not because Nvidia are worse, because the game was developed with AMD's ray tracing in mind, just as every existing RT game was developed for Nvidia.

160 FPS average. I think you missed the point.

That performance is still good.

EDIT, Doom is also not a new game, see my posts above.

Its not about being good.. more about having gaps to fill in the portfolio (I have updated the post with data on RX 6800/6800 XT)
And Doom Eternal will probably be the most advanced Vulkan implementation atleast till 2023 (i know i am being cynical)

I also checked Serious Sam 4
RTX 3090 131 fps
RTX 3080 120 fps
RTX2080 Ti 95 fps
RTX 2080 Super 78 fps
RTX 2070 Super 69 fps
RX 5700 XT 68 fps
GTX 1080 Ti 68 fps

https://www.computerbase.de/2020-10/serious-sam-4-benchmark-test/2/#diagramm-serious-sam-4-2560-1440

If RX 6800 XT performs similarly at 120 fps, there needs to be something sitting at 80-90 fps which should be the RX6700??

Nice score. Beats mine by around 5% :D

You are still missing the point, i was talking about 5700 XT performance to Martini, i was not talking about 6800 / 6800 XT.

Dude, AMD ray tracing wont get faster with new games its the hardware that is slower. The only way AMD's RT gets faster is if newer games reduce the quality or have very limited RT. Like Dirt 5 for example, its just RT on the car's shadows the game is 100% rasterasation. You need to stop cherry picking your data and trying to mislead other people. In DXR Nvidia completely dominates and its hardware that is the cause. In RT the 6800xt is slower by 34 and 64 per cent depending on the game. The 6800XT is -6.9% slower than the 3080 in rasterization games at 4k. https://www.3dcenter.org/news/radeo...ltate-zur-ultrahd4k-performance-im-ueberblick Game optimisation techniques is not the cause.

RT performance is poor for the RX 6800 XT, with the AMD card trailing by between 34 and 64 per cent depending on the game. https://www.eurogamer.net/articles/digitalfoundry-2020-amd-radeon-rx-6800-and-6800-xt-review?page=7

milarly, let's consider the RX 6800 XT and the RX 3080. At 4K, we're seeing anywhere from a narrow three per cent lead over the 3080 to a 24 per cent deficit, although the disadvantage is normally in the region of three to eight per cent.

Smart Access Memory is a really cool technology that does work great in some games, even though 10 per cent performance gains seem to be the exception rather than the rule. In most of our testing, we saw only one or two per cent uplifts in performance, especially at 4K where AMD really needs the additional firepower that SAM could provide. However, this is essentially free performance if you have the right hardware, so even minor gains are still a net positive. Likewise, the fact that AMD can compete with the 3080's GDDR6X memory proves that their Infinity Cache idea holds water - even though the broadly stronger relative performance at 1440p than at 4K suggests that the approach might have its limitations.

Someone got 2650 Mhz on RX 6800 XT on reference air cooler:

Not bad not bad, looks like good OC headroom on the 6800 / 6800 XT with the reference cooler.

Can't wait to have a play myself, was never able to do any overclocking on my Radeon VII as i used the reference cooler.

Do you know how many games that are available that support DLSS and RT? I thought it was only supported in a dozen games.

I've not bothered trying to OC, happy enough at stock :)

Can you please try pushing clocks at stock voltage with a slightly increased TDP, radeon software is supposed to make it very easy.. curious lol.

I think i was following the broader conversation where performance gaps were being highlighted with the possibility of taking 5700 XT EOL

Regurgitating the same thing and quoting a couple of reviewers to back you up is not a be all and end all to your argument winning, lazy is what it is and no matter how many internet commentators you can dig up repeating the same blanket statements it doesn't make those any more valid than my arguments.

They looked at a few RTX branded games and concluded "Slower = bad hardware" like the naive logic you would expect from todays tech journalists who wouldn't know how to think outside adding two together let alone analyse anything.

I disagree with you, i have given my reasons, repeating yourself isn't going to change it, try reasoning your arguments, then we can have a conversation.
 
I think the 6900xt and the 3080 trades blowes, they're similar performance.

Ray tracing is unclear at the moment, perhaps the 30 series has better hardware, we'll see.

The main concern is, will 6800 series PULL AHEAD in the future due to console optimised ports, which in some cases in the past Nvidia may have still had better performance, but it's unclear going forward.
