With whisper-bench I'm getting...

ggml_opencl: selecting platform: 'NVIDIA CUDA'
ggml_opencl: selecting device: 'NVIDIA GeForce RTX 4070 Laptop GPU (OpenCL 3.0 CUDA)'
Unsupported GPU: NVIDIA GeForce RTX 4070 Laptop GPU

Compiled with MSVC Win11 ...

-DGGML_CUDA=1 -DGGML_OPENCL=1 -DGGML_OPENCL_USE_ADRENO_KERNELS=0

Is OpenCL only for phones or something? I've run some OpenCL tests in the past so know OpenCL works, just GGML has problems

OK, CUDA is going to be faster - I just want to run comparisons. I've also got Vulkan support compiled in and that's only slightly slower than CUDA

The Adreno flag sort hints at a possible issue I guess but can't find anything saying it WONT work.

Possibly vckpg's opencl is an issue? [it's openvino was an issue]
