A bit of the GPU latency problem is inherent to the memory used on modern GPUs. The GPU would still have to copy its working data from main memory to the GPU memory (even with the new memory addressing scheme). Having to wait for the data to be moved over the PCI express bus because you have to wait for the memory clock on the system RAM, then the PCI transfer , then the operation...
