6800XT

[Gerard]

Other than another bump in price?

Well its reckoned it's 4k performance is due to the smaller bus size, HBM could have made that a non issue. Probably would have bumped the price up a bit though.

 

[Chuk_Chuk]

A side grade? It’s a 6800 not a 6800 XT. A 3080 beats the 6800 in all aspects so I’m not sure about that..

The reason i called it a sidegrade is because while the 3080 is faster than then 6800, the difference isn't big enough to warrent a new GPU purchase (assuming you are getting framerates that you are happy with). If you are getting good framerates with the 6800 you probably won't notice the difference.

Lets word it another way. Lets say you owned a 3080 and the 4080 came along and it was only 20% faster at raster performance. Would you buy it? Personally I wouldn't.

The specific features that are better.....RT..

I didn't ask that question.

Unless there is a Nvidia feature that you specifically want, there is no point swapping out a 6800 for a 3080FE. It will be more of a sidegrade

Edit: Also @Wrinkly Is wrong. AMD's 4k performance has nothing to do with the memory configuration.

Judging by the fact that you bought a 6800 and went through the hassle of importing it, I assumed that RT isn't really that important to you. If it was you would have bought a cheap GPU and waited for the 3080 to come back in stock; Most telling is if RT was an important feature for you, you wouldn't even be asking this question about if you should swap out a 6800 for a 3080.

And the enhanced FPS bump in 1440p/4K gaming.

See above comment about sidegrade

edit....forgot...also the use of DLSS.

See above comment about RTs importance as a feature.

So why doesn't it do so well at 4k?

Other people have answered you, however focussing on the memory bandwidth point; from all the reviews i have seen, OC the memory does not offer a significant bump in performance, therefore bandwidth is not the main bottleneck at 4k.

Edit: ReBar is scheduled for release in March as stated by Nvidia, we also don't know how it will perform once it is released.

 

[4K8KW10]

There is absolutely no information which indicates that AMD's DLSS competitor will be delayed until RDNA3. It could be released at anytime this year and is not linked to RDNA3 at all.

This is all wrong.

AMD has RB, VRS and SAM.
Radeon Boost,
Variable Rate Shading,
Smart Memory Access

And the gamer can always lower the settings from Ultra High to Very High, or High in order to get even more frames per second, while still delivering better visuals than any DLSS from a GeForce lol

The bandwidth is never going to get massively increased from a memory oc, 256 does seem rather anemic compared to the 320 of the 3080. The fury x still dumps on them both with its 4k bus .

It has Infinity Cache with 2048 GB/s memory bandwidth

As others have already said, you will not get much of a performance increase in memory OC. If bandwidth is not a problem on a 256 bit bus then why waste GPU area with a large cache?

So why doesn't it do so well at 4k?

NVIDIA has stated that they will be adding support for the feature through GeForce Game Ready Drivers and it will be compatible with both Intel and AMD CPU based systems. Having support on both AMD and Intel platforms might give NVIDIA an edge since AMD's solution only works with its Ryzen 5000 lineup and compatible X570 motherboards. The driver is said to launch in late February so around the same time as the availability of the GeForce RTX 3060 graphics card.

LOL the resident Nvidia worshipper spreading misinformation as always. There is absolutely no information which indicates that AMD's DLSS competitor will be delayed until RDNA3. It could be released at anytime this year and is not linked to RDNA3 at all. Cyberpunk RT support will come with the PS5/XSX versions which are scheduled for 2nd half of this year which does not definitely mean end of the year like you imply.

Also RT is around 30% slower on AMD cards, not 50%.

Maybe you fanboys just get upset with facts? If AMD had decent RT then I'd be using a 6800XT right now. Maybe instead of RDNA they should have used codename Cartman, as anytime RT is mentioned the fans throw a tantrum

The poor performance of RDNA can't really be measured yet as AMD keep running away from RT, but so far we can get a glimps of how far behind AMD are depending on worklaod.

Scaling at 4K is very good on the whole for Big Navi. Perhaps it is more to do with other GPUs scaling poorly at resolutions below 4K.

Who buys £600-£900 cards for 1080p?

This is all wrong.

AMD has RB, VRS and SAM.
Radeon Boost,
Variable Rate Shading,
Smart Memory Access

And the gamer can always lower the settings from Ultra High to Very High, or High in order to get even more frames per second, while still delivering better visuals than any DLSS from a GeForce lol

1. Variable Rate Shading is not unique to RDNA, but nice to see AMD are catching up.
2. Radeon Boost, software that lowers your resolution due to your GPU not being powerful enough.
   
3. Smart memory access, or Resizable BAR as everyone else calls it. Coming to both Nvidia and Intel.

That's great, buy a next gen card that doesn't do next gen so well so lower the settings instead of buying the right GPU to start with

............SNIP

WOW...seriously some issues here. Mate enjoy your card instead of working overtime to try and sell Nvidia cards.
We know AMD cards have crap RT. Happy???

Fair point but you would expect a good performance uplift from a memory OC if that was an issue. But from what i've seen it is really small or non existent.

As others have already said, you will not get much of a performance increase in memory OC. If bandwidth is not a problem on a 256 bit bus then why waste GPU area with a large cache?

"Waste" space on a cache or "waste" power on a bigger bus. The standard decisions/tradeoffs that engineers have to take. Seems like fanboys can't admit that it is an elegant solution, till Nvidia does the same thing i guess.

I also never said that bandwidth is not a problem. I said bandwidth is not the main bottleneck (for 4k for the RDNA2 GPUs.)

For desktop systems to get the benefits of Resizable BAR, you will need a graphics card, motherboard and graphics driver that support the feature. New GeForce RTX graphics cards starting with the GeForce RTX 3060 will have support for Resizable BAR. NVIDIA and our GPU partners are also readying VBIOS updates for existing GeForce RTX 30 Series graphics cards starting in March.

People who want to play games with RT on max

1. Radeon Boost, software that lowers your resolution due to your GPU not being powerful enough.

*Cough*DLSS*Cough*

Spoiler

Best keep that 2m distance

 

[Dontrocktheboat]

6900xt on par with 3070 Raytracing performance.

that's not too shabby, could have been worse...

enable DLLS with 3090, plays at 8K

Yes in the be all end all feature that every game supports..oh wait.

I'm not sure RDNA can manage 1080p with RT.

I'm playing at 1440p with a 3080 and an old 3770k Ivy Bridge system circa 2012, while others are using 4k.

Oddly enough I did say I some time ago that I liked AMD's solution. The problem is though that the next gen performance is so poor.

Maybe you need to look up the definition of fanboy

I’m guessing by “next gen” you mean Ray-Tracing? If so then there’s not much to play in the next gen. AMDs cards are on par if not ahead of nVidias when it comes to the tech used in 100% of all other games.

We've all established they're not on par or ahead in all settings.

From what I've seen Nvidia are 6% ahead in legacy and 100% ahead in next gen. That's next gen meaning RT only as AMD lack any form of DLSS.

Maybe this is why people are buying RDNA2, they just didn't research thier purchase first.

Guessing that was before the Nvidia PR manager gave you a stern talking to

Also RT=next gen lol.

I did, i found a pic of you in it

Angry fanboy again

Every time I see such gum flapping I ask why buy a next gen card when it doesn't do next gen? That's why I went Nvidia this round, AMD are still a generation behind.
