Compare DirectX 12, Mantle and DirectX 11 with 3DMark

Compare DirectX 12, Mantle and DirectX 11 with 3DMark We’re excited to introduce our new 3DMark API Overhead feature test – the world’s first independent test for measuring differences in DirectX 12, DirectX 11 and Mantle API performance. It’s also the very first public application to use DirectX 12 full stop. This is cutting edge stuff Developed with input from AMD, Intel, Microsoft, NVIDIA, and the other members of our Benchmark Development Program, the 3DMark API Overhead feature test lets you compare the performance of DirectX 12, DirectX 11, and Mantle. The purpose of the test is to compare the relative performance of different APIs on a single system, rather than the absolute performance of different systems. The API Overhead feature test is not a general-purpose GPU benchmark, and it should not be used to compare graphics cards from different vendors. (We are working on a DirectX 12 benchmark with game-like workloads, which we expect to release soon after the public launch of Windows 10.) Why is API overhead important? There has been much talk this year of new graphics APIs that let developers code ‘close to the metal.’ And though it’s natural to think of the GPU, the benefits of APIs with lower overhead are actually achieved by making better use of multi-core CPUs to streamline code execution and eliminate software bottlenecks, particularly for draw calls. The API (Application Programming Interface) has been an essential co...
