Mantle Programming Guide and API Reference
This is the revision 1.0 of the programming guide and API reference for Mantle, published in 2015.03.06, and its whitepaper published in March of 2014.
Mantle is a initiative from AMD to create a new programming model that can fully exploit the capabilities of modern GPUs.
In collaboration with leading cross-platform game developers, AMD has created an API specification and graphics driver that enable this model on PCs with graphics hardware based on the Graphics Core Next (GCN) architecture.
Mantle is all about removing the obstacles that constrain game developers today and allowing them to unleash the full power of modern GPUs.
This white paper describes the motivation behind the creation of Mantle and provides a high-level overview of its most important features and benefits.
The Mantle API imposes upon PC graphics developers a new set of rules.
Because of the abstraction level in Mantle, which is different from previous graphics API solutions in the PC space, some developer expectations need to be adjusted accordingly.
Mantle attempts to close a gap between PCs and consoles, in terms of flexibility and performance, by implementing a lower system-level programming model.
In achieving this, Mantle places a lot more responsibility in the hands of developers.
Due to the lower level of the API, there are many areas where the driver is no longer capable of providing safety, performance improvements, and workarounds.
The driver essentially gets out of the developers' way as much as possible to allow applications to extract every little bit of performance out of modern GPUs.
The driver does not create extra CPU threads behind the application's back, does not perform extensive validation on performance critical paths, nor does it recompile shaders in the background or perform other actions that application does not expect.
When using Mantle, developers need to take responsibility for their actions with extensive validation: fixing all instances of incorrect API usage, efficiently driving GPUs, and ensuring the implementation is forward looking to support future GPU architectures.
The reason for this is that in order for the driver to be as efficient as possible, many problems can no longer be efficiently worked around in the driver. This extra responsibility is the cost developers have to pay to benefit from Mantle's advantages.
Mantle is designed for those graphics developers who are willing to accept this new level of responsibility.
