ARM Immortalis GPU - mobile with Hardware RayTracing

[Lurkmass]

Lets hope nobody will port the UE5 over to the mobile world.

Don't worry, UE5 will have the lower quality forward renderer (doesn't support ray tracing) available for common mobile/VR games or Nintendo consoles just like UE4 and most mobile graphics hardware still won't be able use all of UE5's feature like Nanite for different reasons ...

Epic Games also recommends against shipping games with the console/desktop or mobile deferred renderer on mobile devices since Qualcomm's Vulkan drivers are still mediocre. Unity's HDRP renderer (required for ray tracing) only works on iOS mobile devices as well ...

So we now have PowerVR's IMG CXT, ARM's Immortalis/MediaTek, Samsung's RDNA2, Snapdragon 8 Gen 2, and now Apple.

The A16 had plans for Hardware RT support, they were scrapped, so I guess A17 then?

A16 Bionic GPU Had Ray Tracing Support, But Ambitious Apple Engineers Found Many Flaws In Earlier Versions

The A16 Bionic GPU could have been even more capable, but Apple engineers were too ambitious in their plans, according to one report

8 gen 2 gpu is currently the fastest mobile phone gpu.

Ray Tracing is rather slow? So perhaps power draw or thermal output are unaffected here. Often we cross difficulty of workload with being the same as saturation. What often drives up the power draw and thermal workloads is really FPS. You hit the entire pipeline more times per second the higher the frame rate. RT only adds a singular additional step in a pipeline.

A low frame rate doesn't mean low power nor does high FPS necessarily mean high power. When there is correlation between low power and low FPS it probably means low utilization of resources and that is the reason for the low FPS.

After more information has been revealed what do others here make of the fact that mobile GPU vendors can only support inline ray tracing as opposed to RT pipelines/PSOs on their Vulkan drivers ?

Basemark is making a mobile RT benchmark. devices have been tested and will run at 15fps at 1920x1080

The medieval 3D ray-traced scene won’t render faster than about 15fps on 2022 devices, but is built for the future.

Early performance figures of the Vivo X90 carrying a MC11 Immortalis GPU in Geekbench: https://gfxbench.com/device.jsp?ben...G715-Immortalis MC11&did=111394576&D=Vivo X90

Some weird differences in different tests compared to other GPUs, but it scores overall quite well. I personally expect to see this round from ULP SoC GPUs in the Android world performance that is around Apple M1 performance.

So now it's official, A17 is supports Hardware Ray Tracing. Using a custom demo, Apple compared A17 with Hardware RT vs A16 with Software RT, and A17 was found to be 4X times faster.

3DMark has been updated for iOS and Android, but I cannot find some results with HW RT. My mom's iPad 9 gets ~2600 in Solar Bay IIRC.

The only question is is it (customized) CXT or actually "Apple design" like they claim

Apple design with a GPU "architectural license" IMHO.

OT: Isn't it way OT for an ARM/Immortalis thread?
