I want an RTX Addon Card!

yeh defo would be interested in a RTX addon card, with the performance of the new cards not being much better, cant see nvidia making one though, but it looks like sales of the RTX cards wont be as good as they where expecting

perhaps they could make a cut down gpu, that just mainly handles RTX stuff, youd install it in your machine, then youd select RTX on the addon card in nvidia drivers, much like you do with physx
 
I don't think it's technically possible to have an RTX add in card (at least not financially viable). It would need to access the VRAM on the GPU and have knowledge of lighting sources, surfaces and objects which do not appear in the rendered frame. It might be possible with an Nvlink connection, but would probably cost to much to make it worthwhile over a GPU with integrated RTX cores.
 
I could maybe see an RTX accelerator for the existing cards connecting over NVlink, or perhaps SLI will have RTX acceleration mode or something.
 
As other have already said, the RTX core needs to be on the same chip to work without massive bottlenecking.

Even a separate chip on the same board would be very poor if you could get it to work at all.

If they could do this for Ray Tracing, multi chip GPUs in parallel (on the same PCB) would already exist for current GPUs as it would be a lot cheaper to put multiple small GPU chips and combine them on the same PCB than the current single chip.

Yes that's an example of serial process, crossfire & sli.

If it was possible to run them in parallel (not split tasks like half screen for each chip) as if they were a single chip it would be a game changer, but at the moment that's not feasible if it ever will be.
 
If this were possible - & I doubt that it is, why would anyone buy it? Microsoft haven't released the update so even if there were any games (which there aren't) you still wouldn't be able to use the card, and I know there are a few loons out there, but seriously who wants to drop £300 on a card which does nothing?

GTX 1080Ti are fetching £500 as a minimum on Ebay so put that together with your £300 for a seperate RTX card, and bingo! You have enough for a brand new RTX 2080.

Problem solved !
 
Problem isn't solved. The problem of RTX 2080 is that it is too weak for meaningful ray-tracing. And you need to wait at least a couple of generations to see it actually properly work.
