Actually it's quite the opposite as the question. AMD using mantle has moved some of the load away from the cpu... but I guess that is only for mantle optimized games... including mantle in this question would mean that the AMD cards are actually less cpu dependant. This is why the actual cpu cores on the xbox1 and ps4 are far less powerful and lower clocked than a standard AMD/intel cores, they seem to be closely related to the amd "bobcat/jaguar" mobile cores.

So.... less dependant actually thanks to mantle a la AMD drivers

Here's an older article from 2013. It's mainly about Gameworks, but it gives some insight into both camps philosophies in how they approach game developers, and what their focus is.

http://www.extremetech.com/gaming/183411-gameworks-faq-amd-nvidia-and-game-developers-weigh-in-on-the-gameworks-controversy

A quote from the article by Valve programmer Rich Geldreich

“[T]here are fundamental limits to how much perf you can squeeze out of the PC graphics stack when limited to only driver-level optimizations,” Geldreich told ExtremeTech. “The PC driver devs are stuck near the very end of the graphics pipeline, and by the time the GL or D3D call stream gets to them there’s not a whole lot they can safely, sanely, and sustainably do to manipulate the callstream for better perf. Comparatively, the gains you can get by optimizing at the top or middle of the graphics pipeline (vs. the very end, inside the driver) are much larger.”

Geldreich spoke directly to this question, saying: “I don’t think NV is purposely tilting the table here. But if you look at the big picture, I wouldn’t preclude a sort of emergent behavior that could effectively tilt the competitive advantage to whatever vendor manages to embed the best developers into the most key game teams.”

Other programmers told us something similar. No one thinks Nvidia purposefully designed GW to ruin AMD’s ability to optimize, but everyone is aware of how de facto control can be used to tilt competitive situations. Given that AMD tends to rely more heavily on source code optimization, it appears to be legitimately more difficult for them to improve performance on GameWorks titles.

Whether its gameworks or mantle, both companies genuinely want to help development as best as they can. AMD will focus on the game engine's source code and optimizing there, Nvidia may also do that as well as more focus on driver optimization. Both companies would love for you to be using their middleware solution(s) or mantle. It's great for marketing.

In less than a month, dx12 and new drivers will be out. Do I particularly care if nvidia drivers have more or less overhead in dx11? Not a single bit. There's literally nothing I can do about it. I like features and performance (eye candy and fps). If it gets me where I want to go, good.

No mantle uses the gpu to process some elements rather than the cpu... thus decreasing cpu load.

This is half true, becasue in addition spread API/driver load on many threads instead 1 thread in Dx11.
