AMD Navi 23 ‘NVIDIA Killer’ GPU Rumored to Support Hardware Ray Tracing, Coming Next Year

Don't get me started on Laptops. I'm sick of getting test units to ensure they are suitable before trying to pick a couple that will be the standard for the business. Then we do it goes EOL few months later, got me raging! Never had to mess about with getting task sequences working for imaging so much.

Aye all the chinese branded webcams shot to the top in amazon lol.

OMG absolutely that. We even had a couple that were DOA or a couple of keys on the keypad were duff. Some items I seen were refurbished HP lines that just had an SSD put in them instead of the regular mechanical disks..
 
No my friend . No rtx or dlss was used by techpowerup reviews.
These are just AMDs hand picked cherry's. Problem is, 2080 had a lot more cherry's in its basket than VII.
What exactly is the problem? You think VII should not have been targeting 2080?
Target 2070, get a convincing win, sell cheaper? What they eventually did with 5700xt

Or that manufacturer presents their product in a good light?

I don't mind big navi at -10% performance to 3080, priced accordingly.
I do mind if they overclocked the wheels off it in attempt to catch up and look good in reviews

I am just speculating on big navis performance bro. That all. As I would like to get one in my rig at some point.
 
The VII was a compute card as its strong point. Although the 2070 can ray trace, it and its other close siblings sucked at it, only the 2080Ti was worth gloating about being able to use it properly. These posts need to reign it in when trying to berate AMD cards for not being able to ray trace if they cant even do the job themselves.
Yeah, there's a lot of bathing in the reflected glory of a £1200 card :p

Credit to Nvidia for moving things forward, but let's keep things in perspective!

..and even then the 2080Ti struggled at 1440p RTX on with Control dipping below 30fps on medium setting. That's £1200 and shows its still not enough to get the performance, for me thats telling that RTX just isnt ready. High end 3000 series, maybe but the cards below 3080 its gonna struggle.

Yeah, I guess for games with DLSS 2.0 in performance mode, it'll be a bit more viable.

But even then, we're talking a subset of a subset, we need universally applicable performance.

One factor there is - the game is still a mixture of rendering techniques - you have all of the hit of non-ray traced features and ray traced features which are only used for some effects but have much of the overhead of a fuller ray tracing implementation. If the game was exclusively rendered with path tracing for all effects the performance profile would be somewhat different.
 
I can't seem to get enough of these AMD cards, I appear to have just bought another radeon 7, this time a broken Radeon 7 :D Will make a nice ornament if I cant get it working! That should fill my gpu fiddling needs until big navi shows.

I think the developers and techniques will get good at finding the shortcuts or cheats around some of the performance barriers. With it being somewhat a closed shop so far, it will take the wider platforms to make hay on this, so the hardware will get better at running it but you know is there a time limit on this as in two years people will have moved on to another gen of cards and will look back on the Turing or Ampere (low end) stack as a feature available that just wasnt used at the time (due to chunky performance impact).

Yeah - when Quake 2 RTX first came out reflective surfaces were omitted from being present in other reflections due to a huge performance hit doing so (I think it was like 60% lower performance for the first bounce and 120% for the next, etc.) then in Jan they patched it to enable multiple refraction/reflection bounces with only a ~1% performance hit per level.

Yeah I can see big strides like that example happening, I hope its not gonna take months/years though.

There are going to be optimizations they can make, just depends how much effort they put into it.

When battlefield v got ray traced reflections they performance tank was massive, after the devs looked into they found the game was casting reflections on surfaces they never intended such as reflections bouncing off of flowers, grass and other foliage creating a huge amount of extra complexity to the scene and the player couldn't even notice those effects due to it being so damn small - they then went back and tweaked it.

Every developer out there has to do this process, they don't have much experience with this technology so they have to make their first ray traced game to get experience and learn where they made mistakes and what can be improved.

One of the big features of graphics cards today is the programmable shaders and when those first came out they weren't flash either.

Not going to put all the blame on the developers, there is still much room for hardware improvement but hardware is not there to make developers lazy and they will need to work out what is the best way for them to implement this technology.

Taking a page out of history:
On Radeon VII release three cherry picked benches where used then and compared to 2080.
That doesn't work as a point of comparison. It's entirely correct to say that AMD cherrypicked three titles where they're strong for the Radeon VII graphs, but it's entirely wrong to say they've done that again. Borderlands 3 isn't a good title for AMD. It's one where Nvidia are stronger, which is why it was one of the titles that Nvidia cherrypicked to show off the RTX 3080. If you look at the numbers for the 5700 XT in that game, it's slower than a 2070, whereas in most scenarios it beats that card handily. Gears 5 is pretty much the same, with the 5700 XT only matching a 2070 in that game and further behind the 2070S than average. Modern Warfare is really the only "good" title for AMD out of the three, where a 5700 XT comes slightly closer than average to, but again doesn't beat, a 2070S (and there are certainly games where a 5700 XT does beat a 2070S that AMD could have used). Gamers Nexus noted that it was a very even-handed set of titles for AMD to have chosen, without using any outliers where AMD cards do really well. And that is the case, if you check the benchmarks yourself.

-----------------------

So, do people still think that the card AMD showed in their presentation was either the 6800XT or some super-duper-mystery XTX edition? :)
 
Coretek is posting on his blog.

...my previous report of “2080ti + 15%” was below the final performance numbers, at least for this particular model...
You don't say:rolleyes:


Lastly, I was shown the GPU shrouds for both the 6800 and 6800XT (AMD reference models) and they have some small differences. Unfortunately I am not able to publish the images at this point, but looking at the pictures I can tell you that the one that Lisa Su was holding during the 6000s event last week was in fact the 6800XT. The 6800 is slightly different although it also features a triple-fan design. The 6800 seems to be 2 slots while the 6800XT seems to be 2.5 slots judging by how the shroud covers the bracket (unlike the 6800 which has the bracket rolling over it)...
This is for doc purposes. Taken with a pinch of salt. Folk here already assumed that LS wasn't benching top BN. But he's saying that what was shown wasn't top BN at all but 6800xt.

https://coreteks.tech/articles/index.php/2020/10/21/making-sense-of-the-rx-6800-and-6800xt/
 
Makes sense

so the card shown and benched on 8 October and seems like it's going to be at or little bit under 3080 level is the 6800xt

which makes the 6900xt the 3090 competitor - given how close in core count the 6800xt and 6900xt is the 6900xt is likely to be about the same level as the 3090, maybe faster if it can clock higher than the 6800xt
