Could Intel or AMD put ray tracing cores on a CPU die?

[Kippa]

Just curious do you think that Intel or AMD could put the equivalent of RTX ray tracing cores on a CPU die?

I don't see why not, although it would be better if it was closer to the GPU I imagine. nVidia's is just a fixed function block.

But don't you need the tensor cores as well?

 

[Qwertilot]

Need, no - the original btf5 ray tracing stuff apparently didn't (Still doesn't?) use them.

They're very handy for it though

Back in the Amiga days motorola made FPUs you could you could add to the computer. Basically an Accelerator/FPU chip to help with ray tracing. I had one on the 68030. So sure.

Just like QSV has fixed function video transcode it could also have ray tracing, it would cost way too much though as we can see from nvidias cards.
If dx12 ever takes off it could even use the RTX from the iGPU while doing anything else with the normal card.

With core wars' going right now, they don't need special dedicated core for it,

And to be honest I would love if dev focus more on AI or advance physic

CPU raytracing already exists though only for professional rendering applications. Intel has Embree and wide vector SIMD(AVX2 and AVX512) is apparently very useful in accelerating raytracing kernels.
