mrnagantOn Pixel 7A, says "device does not support all the Vulkan features required to run the test". So I assume it needs RT cores. Which mobile processor have RT cores?

Neat.

ZunexxxWonder how would it be compared to 4090, just to see the difference and for fun

dj-electricye shall receive

13900K + RTX 4090

This is very not desktop horsepower kind of test. Much like Night Raid, this is a low power device friendly test
Compared to Videocardz's much lower results, I can assume that at these framerates its entirely CPU and memory bottlenecked

ZunexxxHey, it's 40 times better and a galaxy s23, I will take it, lol

fec32a4deNot sure on the requirements for physical RT cores, but Pixel 7 doesn't have them. The 7 uses G710

Current phone GPUs with RT:

-Arm Immortalis G715 (MT6985 (Dimensity 9200/9200+)
-Arm Immortalis G720 (Not sure if commercially available yet, launched in: Q2 2023)
-Qualcomm Adreno 740 (Snapdragon 8 Gen 2)

edit: Vya is absolutely correct: It was done in software. GTX 1000 series and 1660 Ti for example, which is technically part of 20 series [1660 Ti] but without RT cores.

Some PC games refuse to let you enable RT if physical RT cores are missing.

UL_JarnisSnapdragon 888 has no RT support, so it cannot run on that device.

Snapdragon 8 gen 2 does support, as does Exynos 2200 and latest Dimensity 9200. There will be more SoCs with support in the future.

FM_JarnisTechnically the test requires just Vulkan 1.1 Raytracing extension support. To be exact, following extensions and limitations:

VULKAN EXTENSIONS
VK_KHR_acceleration_structure
VK_KHR_ray_tracing_pipeline or VK_KHR_ray_query
VK_KHR_buffer_device_address
VK_EXT_descriptor_indexing

VULKAN LIMITS
maxSamplerAnisotropy >= 16
maxBoundDescriptorSets >= 8
maxDescriptorSetSampledImages >= 400

VULKAN FEATURES
samplerAnisotropy
Quad ops in fragment shaders

The driver for each platform can choose how to implement these. For phones, currently only devices that have hardware acceleration have implemented these extensions. On Windows side, NVIDIA has implemented these for 10- and 16-series, just like they implemented DXR support without hardware acceleration, so you can run this test (slowly) on those cards.

Future phone firmware/GPU driver updates could, in theory, add the required feature support even for devices that do not have hardware acceleration. This is up to the SoC vendors. Not sure how phone hardware would handle such an implementation - I would expect it to be very slow.

Also note that this is primarily a test for mobile devices. While it scales even up to a RTX 4090 (when paired with a very fast CPU) and care was taken to try to ensure that it is not CPU-bottlenecked on current hardware, the performance difference between, say, Snapdragon 8 gen 2 and a RTX 4090 is so massive that any multipliers of performance you may list out of that are only a rough figure and there is inevitably more variance between runs on high end hardware with a relatively lightweight test like this. RT load was also designed to be appropriate for mobile devices, so it is far lower than, say, in Speed Way or Port Royal. This means that for example performance difference between current NVIDIA and AMD hardware is less than in a heavier test.

Edit: Also, yes, the test is only 115MB. Care was made to minimize filesize as this is a mobile device test and you probably would want to avoid having to download a gigabyte-sized test to a phone. Assets are mostly new and it does not use files from other tests on Windows.
