Not necessarily, some folks advocate that with modern compute APIs we are better doing "software" rendering, but on the GPU.

By the way, this is what renders like OTOY Octane do.

Sadly you can't access RT cores with CUDA, you need to use a graphics API like Vulkan or D3D12. You can make a fast ray tracing based renderer using pure GPU compute, but it'll still be slower than using RT cores.

And even with GPU compute, you benefit from HW acceleration with the HW texture unit.
