AMD shares some RDNA 2 HW raytracing performance indicators

And it says that it has an open and cross-platform DLSS challenging tech in the pipeline.

Read more.

Ray tracing is sitting between 2080 and 3080 but it does need to be pointed out that Nvidia has had 2 years of Turing to optimise how their RT cores work in the drivers.

An interesting start nevertheless if their first offering is doing middle of the road for Ray Tracing.

Well I would argue AMD has room for further optimisations. If you look at RT on a development front,it appears RDNA2 is more optimised for the later inline raytracing standard than Turing is.

I'm not too concerned about RT performance because: 1) I'm not interested in current games that implement it; 2) none of this gen's cards, not even the 3090, can provide 4K60 performance so I probably won't be turning it on anyway whichever card I go with; 3) Xbox and PS5 will offer RT on RDNA2 hardware so they will have to get it working pretty well on RDNA2 for the next 3-5 years. So yeah, not too interested in RT performance numbers at this point in time given how variable the landscape still is and how many things could change.

And as DXR is a more generalised standard and is in consoles, I imagine we could see quite a significant bump as more and more use occurs on it.

Frankly, I want DXR to stamp RTX out, anything needing Gameworks embedded at the detriment of competitors is just not cricket.

Observedly, however, SAM doesn't look like it will detriment the game if you don't have a Ryzen CPU but we'll see!

So roughly at 2080ti level? Not bad for a first attempt, and as mentioned, devs will optimise for this approach at any opportunity they can.

Yeah I think we'll have to wait and see. There might be some neat tricks that devs do on the consoles to access large chunks of VRAM for some reason which SAM would enable on PCs as well, and while I'm sure there'll be a traditional fallback it could get quite slow.

Well eventually it'll be replaced by industry standard CXL which will come with PCIe 5.0 so this could actually be a commercial version of the scrapped CCIX which they were developing which lost out.

At that point, Intel & AMD will be CXL standard with Nvidia and AMD GPUs.

I expect Intel to lock Xe to Intel only because they're arrogant and Raja is an idiot.
