Games Middlware/Engines APIs Drivers HardwareCUDA, D3D/DirectCompute and OpenCL are all "GPGPU" APIs that communicate with the drivers. Whatever happens on the other side of the driver is irrelevant, but yes, they all make use of the same hardware.

No, and yes. They generally both run on the same kind of hardware in your computer, the GPU. But that is only half of the truth.
So CUDA and Compute Shader are two different things (hardware)? But both are GPGPU technologies?
That's true, it uses the exact same shader units on the same GPU(s), just with a different API and language (though in reality it's still a bit more complicated, as the driver config panel lets you dedicate GPUs for graphics and for compute tasks, so if you have more than one card and dedicate one to compute tasks, it may be "generally the same" but "factually different ones").
Maybe CUDA uses the same SMs as Compute Shader but it is approched differently in software?
