It seems SemiAccurate was...accurate - Microsoft just took Mantle and renamed it DX12, to call it their own "innovation": http://semiaccurate.com/2014/03/18/mi

If true, this is a good move by Microsoft. The whole point of this exercise is to be closer to the metal, so why reinvent the wheel. It's something of a Direct3D tradition to design the API around one hardware vendor's state of the art. Direct3D 9 was pretty much based on what the ATI Radeon 9700 could do. At the time this was a serious inconvenience to NVIDIA who had taken a different tack with the Geforce FX (I think it was -- it's been a while).

And it's rumored that Mantle is heavily "inspired" by the Xbox One and PS4 APIs. So really MS is copying themselves.

  They are all inspired by the hardware and the experiences implementing high-content game workloads. The main goal is to reduce CPU occupation and improve parallelism of CPU cores. This is achieved in several ways: - reduce raw CPU work by increasing precompilation of state and data to native formats - reduce communication from the CPU to the GPU, by increasing the flexibility of API calls - reduce CPU <-> GPU dependencies by moving some forms of logic and flow into the GPU All of them conspire to increase parallelism as well since there are in general fewer points where synchronization is needed. Playstation developers have a long tradition of doing these things since the first model; Xbox developers not so much, but still a lot more than on PCs. Since the general goal is to reduce API surface, remove abstractions and match the metal more closely, it's natural for APIs to converge.

  Or maybe AMD making an end-run on easy porting from Xbox-PS4-PC(Steam). Thus making their wares more desirable ?

SemiAccurate is always accurate. One of my favorite sources.

  According to wikipedia, SemiAccurate is a news/opinion site similar to The Inquirer. Is there enough information about the DX12 API yet to confirm this?

    Charlie of SA used to write for The Inquirier. He has some damn good sources. I cannot recall a time when he was ever wrong, and he's broken some big stories (things like the Nvidia 8800/9800 GPU failures). Out of all such rumor sites (Fudzilla and BSN being two other large ones), SA is the only one worth taking seriously.

  Mantle is here and now. With the speed MS is moving that MO is not so scary anymore.
