FYI,

To add to the diagram, a raw input vector will be sent to GPU (VRAM), then got multiplied by a sin and cos vector with the same number of points, element-wise.
The two product vectors are then sent back to the host (RAM).
In practice, I tried to use something called DMA transfer which ideally does not read or write the data from host until run-time, and it should reduce overhead and allowed the read/write to happen together.

For DDC itself, more processing like decimation can be done to reduce the output vector we return from GPU to host, but the feeding of the raw input vector cannot be avoided.

It's been pointed above: only server chips for now. But I wouldn't make a fuss about, it's the chicken and egg problem we get with every new generation. Gotta start somewhere with support ;)
Fair point, I will conceded to that. Just to me its not the best thing to be that early in their current state (Regardless if they are doing it for their professional support).
