With the current directX, firing draw-calls from the CPU is single-threaded. The performance boost mostly comes from using the cpu in parallel to fire draw-calls to the gpu.
Draw-calls are a performance killer. The new directX 12 technology raises the amount of possible draw-calls drastically.
This + some other nice features are going to raise the performance for all directX12 graphics card excessively. (that is - if you split your draw-calls to multiple threads)
