Maxwell-based Graphics Cards - Performance

[Starfox3]

The Maxwell-based graphics cards (primarily Nvidia 800 series) have been touting autonomy- independence from the CPU. Am I to take this to mean that performance will not be bottlenecked by a weaker/aged CPU?

Nope. It doesn't matter what Nvidia says, its all marketing BS.

Doesn't matter how fast the GPU is, if your CPU isn't catching up to it, there will still be a bottleneck in the system. Nvidia GPUs do not have proprietary system like AMD Mantle to off-load CPU stress onto the GPU.

Nvidia is hoping that when Microsoft releases Direct X 12, a low level API similar to Mantle, to shift the work load from CPU to GPU. But being as it is, nobody knows when DX12 will be released. All speculations are going to be on the fact DX12 will be on xbox first and then windows 8.1 and 9 next year.


If you look at the Maxwell based GPUs on laptop that is already out, they don't fair that well. Also, nobody knows when 800 series will be released.
