It’s all compute stuff so even if Volta had a specific optimized operation that Pascal doesn’t it still should be able to be compiled and run. Either way Volta is right around the corner.
There’s a lot of speculation that 7nm process cards will be out Q3/4 this year and that Nvidia is in production now. AMD is expecting 7nm cards around that time too and Nvidia wouldn’t let them release something unchallenged. The other thing is that both manufacturers have said that the 7nm process exceeded expectations so we’re looking at a roughly 3x performance bump.
If the stormtrooper demo was overkill with all bells and whistles on three Titan Vs then you can expect DXR to be a consumer-grade reality for a more modest simulation on the next gen of cards. I can’t ****ing wait to see it.
