Ray Tracing

Maybe they did but last i checked, Apple didnt explain in detail if these “hardware accelerated” cores are dedicated, similar to NVIDIAs RTX. They seem to be very similar to how AMD handles Ray Tracing in a more unified process by just simply using the main Compute Units to do it with brute force. Hence, why the CU count and RT core count are always the same. Its all just marketing trickery.

Newer high-end silicons simply have more GPU TFLOPs that work more efficiently so it makes sense why they allow some of them to perform Ray Tracing, even though it cripples performance. Besides, any GPU can perform Ray Tracing and Path Tracing if programmed to. Recent low-level APIs allow this to be done even easier. Hence, why UE5 (DirectX 12) has been a win with Lumen (Engine level RT).

I might be completely wrong, lol. Regardless, im excited for Snapdragon and Apples new offerings. AMD is also a contender with thier mobile APUs. The 780M isnt a slouch in these gaming handhelds.

The hardware certainly is dedicated. Nvidia puts their RT cores in their own section of the processor die, while AMD puts them inside the texture mapping units within the main shader cores (or so I’ve read, at least). In both cases, there is dedicated hardware for BVH acceleration and whatnot.

Newer GPUs also have more dedicated ray tracing performance to go with the higher general TFLOPS.

Doing ray tracing in software on “any GPU” cripples performance way more than doing it in dedicated hardware like RTX. For example, a GTX 1080 Ti has nearly twice the general-purpose TFLOPS of an RTX 2060, but the 2060 will easily beat the 1080 Ti when it comes to ray tracing performance.

Apple, Snapdragon, and Dimensity are indeed exciting. The Snapdragon 8 Gen 2 roughly matches the OEM GTX 1050 in regular shader graphics performance. The 8 Gen 3 is about equal to a 1050 Ti. If the 8 Gen 4 finally uses 3 nanometre manufacturing, it might get close to the RTX 2060 Max-Q.

Well, this aged like milk.

I was able to run blender 2.79
In my dimensity 6080 chipset 40+ fps
And I also can use rendered viewport(cycles) with lag but it’s minimal. Keep in mind this is emulated.
What if we can get a native path tracing in our hands imagine the speed. I’m praying this will be added in the future :pray::pray::pray::pray:

… what you mean by: emulated? Why not use the arm64 build of blender?
And why you use such an old version?

Just wondering…
