3DMark API Overhead feature test adds Vulkan support

Posted on Thursday, March 23 2017 @ 13:13:07 CET by


Futuremark announced they've expanded the 3DMark API overhead test with Vulkan support. By using this test, you can compare the performance difference of Vulkan, DirectX 12 and DirectX 11 on a single system.
I'm excited to announce that we've added Vulkan support to our 3DMark API Overhead feature test. This means you can now compare the API performance of Vulkan, DirectX 12, and DirectX 11 with one easy-to-use test.

Vulkan is a new graphics API that provides high-efficiency, low-level access to modern GPUs in a wide variety of devices from PCs to smartphones. APIs like Vulkan and DirectX 12 make better use of multi-core CPUs to streamline code execution and eliminate software bottlenecks, particularly for draw calls.

Games typically make thousands of draw calls per frame, but each one creates performance-limiting overhead for the CPU. Vulkan and DirectX 12 reduce that overhead, which means more objects, textures and effects can be drawn to the screen.

The 3DMark API Overhead feature test measures API performance by making a steadily increasing number of draw calls. The result of the test is the number of draw calls per second achieved by each API before the frame rate drops below 30 FPS.

The purpose of the test is to compare the relative performance of different APIs on a single system. 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.
