Are bottlenecked by what?

The whole point of Mantle is that it will move the bottleneck back to the actual GPU itself (where it should be), no more CPU spoon feeding the GPU, so the CPU should, theoretically, never bottleneck the GPU.

By the CPUs... what else would the be bottlenecked by? The RAM is another source of the bottleneck, but not as heavy as the CPU side of things. That is where the APU absolutely fail. You pair a GPU that matches the specs in the APU with a faster CPU and you get significantly better performance. Let alone, multi-GPU solutions with an APU so little to no benefits half the time as the CPU is unable to pre-render frames fast enough, or the RAM latencies are far too great.

Then taking the score of the 290 doing that times 0,65 and deviding the average framerate in the Mantle demo by that number.

Other combinations that could've been used are a 260x with kaveri or a not yet released "250x".

Interesting way he chooses to phrase what he said at the 0:20 mark.

This is up to 45% faster with Mantle than the original version on the same hardware.

He DIDN'T say that SAME version of Battlefield 4 is 45% faster running in Mantle Mode over DirectX mode.

Now while some will think that is splitting hairs, it isn't. Why? Because when you are comparing one version of the game to another, just because you switch from DirectX to Mantle doesn't mean that OTHER FIXES in the game didn't account for some (or all) of that 45%.

So what does this mean?

Until a person not associated with AMD and DICE/EA can get their hands on the game and can run it for themselves and toggle the SAME VERSION of the software between DirectX mode and Mantle mode on the same hardware ... the improvements will be questionable.

What was that 45% bonus on, a system that could run it at 2 FPS, so now its 3 FPS? (JK)
