I do not get this from the graph at all. It looks to me like the overall power draw is the same between DX11 and DX12, but DX12 just directs more power to the GPU and less to the CPU.

For Intel, any game/tech demo that can run @ 30fps using Intel Graphics is consider "spectacular".

well... since intel is having a hand in dx12, i suposed we can assume there is a "if intel; else" series of switched built into it.

Intel is not a benchmark for GPU performance. They need to test Nvidia and AMD Gpu with DX12.

Supposedly the xbox one has something similar that will give the xbox one directX 12 with a firmware update to the system.

I think that's because, according to the text, power is only reduced when the frame rate is capped. The graph doesn't show a capped frame rate.

edit: actually, the first chart here http://www.pcworld.com/article/2465211/intel-microsoft-...
confirms what I said. It shows a 50% reduction in power. I'm sure that's a bit of a best case scenario, but that's still mighty impressive, I think.

Also remember that Mantle is most useful with APU. If you have fast CPU and fast GPU the benefits from DX12 are also quite small!
The DX12 is a good news to anyone who don't have separate graphic card to all else it gives much less. But as we have seen from Mantle, even high end systems get 3-6% more speed and it is not bad at all!
So using Intel build in GPU in these test is good choice because it is the system that benefits most from these close to metal programming.
Not sure if we could see some really graphically demanding games, then closer to metal programming could also be more useful in high end system. But if games are not made for Xbox360 and PS3 and maybe even to Xbox one and PS4 the games are not going to be very demanding in the near future.

Is it that time of year again when Intel pretends it makes GPUs?

Especially mobile APUs which are constrained by power and/or temp. I'm sure this will extend to the similar-concept DX12 as well.

Why name it DX 12 ?! Why not just 11.1 as it's just a miniscule update that doesn't even require new hardware... Is this microsoft's money grabbing tactics (via bubble) to get people into Windows 9 ?

Obviously, if there is no improved visuals or tools, gamers wont care. And since gamers are the only consumers that buy new PCs before their previous one is gone dead, this is an ad from a desperate company.

DireftX 12 will be used as a selling point for Windows 9.
The power saving and efficiency improvements are improvements everyone can benefit from, not just power users. More efficiency always benefits everyone.
DirectX 11 is part of Windows 7
DirectX 11.1 is part of Windows 8
DirectX 11.2 is part of Windows 8.1

"Why not just 11.1", Really? Adding proper and supported multi-core rendering is the biggest thing to happen since sliced bread.
