How will Nvidia react to the AMD 6000 series launch?

No that's different. RTX IO is the card having direct access to fast storage ie an NVME SSD (which AMD also has under a different name). We're talking here about the CPU being able to directly access the GPU's memory.

Am i right in saying that the RTX IO/whatever AMD calls it is actually more an OS feature, and fully supported by both vendors? The smart memory is an additional AMD only feature if you have the full suite of products?

I'd love to see some benchmarks comparing those two technologies. Presumably the nvidia implementation uses RT cores or tensor or whatever to do the decompression of assets. though i'm guessing any cores are better than CPU cores.

Yes, Nvidia have basically rebranded their implementation of Microsoft's Direct Storage API as RTX IO. AMD support Microsoft's Direct Storage API which was confirmed in the Big Navi reveal. The only problem might come with Nvidia modifying things unnecessarily to make their sponsored games not work on AMD without significant developer effort. However, this is a concern with RTX raytracing implementations too.

SAM is a completely different feature that increases performance (by ~2-13% depending on the game) by letting the CPU access all the GPU's memory at once (it's currently limited to only 256MB without SAM, an artefact of the past). To take advantage of this you need Ryzen 5000 and Radeon 6000.

GA100 could show up but most likely in Titan form as it will be disgustingly expensive at something like 3K a card.

So you'd only be getting 1 of them, Kaap?

There is just no way Nvidia will allow the 6800XT to go unchallenged, via a Ti/Super version, with 12GB VRAM, Yes it may mean you have to wait until early 2021 for your new & improved spec 3080, but so what?

And how would Nvidia price this cut-down 3090 in order to make it viable in any possible way?

The profiles used in the benchmarks suggests they did use RT, like with BFV DX12 Ultra profile has DXR on Ultra mode.

I too have a 3080 on preorder, tempted to cancel but I know getting a 6900XT will likely be hard as while 7nm is apparently better yielding, AMD is plagued by the crypto mining horde which will no doubt be looking to replace the 5700XT farms with 6000's, then you have the scalpers/scripters and everyone else...

Mate they did not use ray tracing they would have said they have been very quiet about it i wonder why.

Nvidia will likely just hire a few hundred more engineers to develop DLSS profiles for every game, rendering AMD's hardware advantage irrelevant.

what hardware advantage a few cherry picked games like Borderlands 3 which perform well with AMD software what about the hundreds of other games lets see metro exodus with raytracing on at 4k then we will talk or control even.

I bought 2 Titan Vs

Then found out that they did not support SLI. :eek:

All of OcUK appreciate the mistakes you make so we don't have to

Because you can't give benchmarks on something that doesn't exist?

Tell me when DirectX 12 Ultimate was released
Now list the games available that use DirectX 12 Ultimate's RT API
Now of those games, tell me which developers had access to RDNA 2 dGPUs for development and testing

I'm inclined to think the number will be a big, fat zero. So if there are no games which have been developed and tested alongside RDNA 2 dGPUs, there cannot be any performance figures to cite or demo. And those games that implement Nvidia's RT cores through DX12U are very likely to have been massively optimised for Nvidia's hardware, given they've been the only RT cards available for 2 years.

It's simple enough, no need for conspiracy or insinuations. Especially given the AMD event had interviews with some developers working with FidelityFX, and a couple of them showed their RT efforts. But I take it you missed the Godfall demo.

They have published fps numbers on a synthetic DXR test for an unknown SKU

AMD 471 fps
3090 749 fps
3080 635 fps
3070 475 fps

It is speculated that AMD might have tested either the 6800 XT or 6900 XT..

So you're saying the AMD footnotes were lies?

Be interesting to see Quake/Minecraft RTX benchmarks vs 3080 etc.

They lied about them being out before the consoles

I can speculate though.. the perf difference would widen in real world apps.
As per leaked Xbox slides, a CU can either do 4 ray box intersections or TMU operations per clock.

That's what I want to see even though both titles have been optimised by Nvidia.

Quake 2 RTX won't run on AMD cards in its current iteration

I have to be honest and whilst I like the 3090, my money will be heading for the 6900, as so far* it looks like the best card for me with my budget. NVidia do fantastic cards but the price thing is getting to me now.

*I will need to see independent reviews of course and RT is a thing I like a lot but if the 6900 can hold its own, I am in.

AMD drivers no thanks mate get a 3090 Greg DLSS and raytracing will be big in the future if the new consoles have it developers will put it in games as it will no longer be niche.

Seriously, give it a rest. It's so tired now it's not even funny.

Well after 290x had black screens for 2 years then i heard problem is back on 57xx and took 8 months to fix then ye id say that would stop ME from buying day 1.
