I hope these results start to put an end to the farcical idea that major high level APIs are grossly inefficient at utilizing GPU resources, at least when backed by enough CPU horsepower (even if enough
is quite extreme).

Not a game and CPUs haven't been efficient Bitcoin miners for at least three or four years. So I'm not sure how this is even a joke.

Only if NVIDIA bothers to release a driver that supports Mantle.

-Crossfire basically not supported (big bugs and lots of stuttering)
-limited laptop support
-no portrait mode support
-Since there are so many known issues AMD made a web page specifically for those issues
And that's just what AMD is telling reviewers and enthusiasts.
Most people with Hawaii parts will still see some perceptible increase in performance (multi-GPU setups being a small minority), so I don't see a good reason not to use Mantle, if it's available. If other issues are encountered, it's not like you can't just revert to the DX renderer.

However, do they have enough incentive to add support for a competitor's API?

Was this even ever a question?
There are situations in several games where I am blatantly CPU limited by a 4.4GHz 3930k (paired with DDR3-2133 CL9) and any single high-end GPU. Most of them are badly threaded, but some are not.
The game I currently play most often (PlanetSide 2) is still CPU limited after two performance updates that dramatically increased it's ability to support multiple threads.

Intel's deciding to go with quad channel memory controllers on the LGA-2011 platform has nothing to do with games or DX. It's largely because to support a large number of CPU cores (initial parts had up to eight cores, and the current number of twelve was always going to happen) and a huge amount of I/O, you need a corresponding increase in memory bandwidth.

BF4 won't be the last game to support Mantle, just the first.

He implied nothing of the sort.
He's pointing out that this was a stock 3.5GHz 3970X and that the game was being run at 1080p. Most people on OCN with such hardware would be running the CPU about 1GHz faster and be using 1440p or higher resolutions with the GPUs used. Both of these things would significantly narrow the Mantle lead, due to more GPU limited settings, and a 30% faster CPU.

Yeah, if the only thing you do with your CPU is game. I'm more CPU limited now than GPU limited, mostly not due to games.
By the time a 590X is out, my 3930k will be in my mother-in-law's crapbox or up on the OCN marketplace for 75 dollars.

This is certainly true.
I don't think I have any recent games where I could target a constant 120fps and not be CPU limited in them, even if my GPU could manage it with ease.

The problem is that Mantle will have to become widely adopted first, and even then, consoles have slow CPUs, so anything intended to run on them won't be taking advantage of a high-end PCs CPU prowess.

I'm not sure how you equate using something less with catching up.

Drivers prior to 14.1 do not have Mantle support.

Draw calls are still directed to the CPU (no real way around this), there are just much less of them with Mantle and they are better threaded.

Gulftown has considerably more
