The first two articles about Mantle have differenct ideias about it (or I can say the same)?
Mantle appears to have much in common with the GNM API used in PlayStation 4, offering low-level GPU access while retaining a very high level of compatibility with Microsoft's existing programmable pixel shader language (HLSL). The potential here cannot be under-estimated - much of the optimisation work that is carried out on console versions of multi-platform games can now be rolled out to the PC version too. In addition, there is also the opportunity to exploit AMD-specific hardware features that are under-utilised - or perhaps not even implemented at all - in DirectX.
What’s not being said, but what becomes increasingly hinted at as we read through AMD’s material is not just that Mantle is a low level API, but rather Mantle is the low level API. As in it’s either a direct copy or a very close derivative of the Xbox One’s low level graphics API. All of the pieces are there; AMD will tell you from the start that Mantle is designed to leverage the optimization work done for games on the next generation consoles, and furthermore Mantle can even use the Direct3D High Level Shader Language (HLSL), the high level shader language Xbox One shaders will be coded against in the first place. Let’s be very clear here: AMD will not discuss the matter let alone confirm it, so this is speculation on our part. But it’s speculation that we believe is well grounded. Based on what we know thus far, we believe Mantle is the Xbox One’s low level API brought to the PC.
What do you think guys?
