Intel is hitting the poke on Nvidia:

"When you have a title that is optimised for Intel, in the sense that it runs well on DX12, you're gonna get performance that's significantly above an [RTX] 3060,"
"And this is A750 compared to a 3060, so 17%, 14%, 10%. It's going to vary of course based on the title."
"And so from my perspective, the gamer says, 'Okay, if I want to play DX12 right now, I'm gonna get an amazing value.' You're gonna get a card that's faster than 3060, at prices that are lower. If you think you're playing DX12 and DX11, and you're splitting it, you're still gonna get amazing value. Because we're gonna price it for the performance that we're delivering today.

I've only the CliffsNotes version and not a complete whitepaper, but one important puzzle piece to this touted performance is a BVH cache within the GPU. This is solely used to accelerate BVH traversal—BVH stands for bounding volume hierarchy and is a cornerstone of how modern ray tracing is implemented in real-time in games.
"We tried to make ours generic because we know that we're not the established GPU vendor, right. So all of our technology pretty much has to work with low dev rel (developer relations) or dev tech engagement. And so things like our cache structure and our hierarchy, you know, our thread sorting unit, which are the two techs that we're going to talk about in this video, they work without any dev rel or dev tech work."
"I'm kind of torn on this one. Because to your point, there's some things that you would normally expect to lag. And the reason you would expect them to lag is because they're hard, and they need to come after you have a solid base. But for better or worse, we just said we need all these things. And so we did XeSS, we did RT, we did AV1, we kind of have a lot on the plate, right? I think we've learned that maybe, you know, in this case, we have a lot on the plate and we're gonna land all the planes, and that's taken us longer than we would have expected.
