3DMark Sky Driver is the latest test in the world’s most popular benchmark for measuring the 3D graphics performance of gaming PCs. Sky Diver includes a Demo, two Graphics tests, a Physics test and a Combined test. The Graphics tests measure GPU performance, the Physics test measures CPU performance, and the Combined test stresses both GPU and CPU. The Demo does not affect the score.
Graphics test 1 focuses on tessellation and uses a forward lighting method. Graphics test 2 focuses on pixel processing and uses compute shader-based deferred tiled lighting.
The Physics test introduces a new approach that extends the performance range for which the test is relevant. The test runs through four levels of work starting with the lightest and continuing to the heaviest unless the frame rate drops below a minimum threshold. The GPU load is kept as low as possible to ensure that only the CPU is stressed. The test uses the Bullet Open Source Physics Library.
The Combined test contains both graphics workloads and physics simulations to stress the CPU and GPU. The test uses a compute shader-based deferred tiled lighting method.
Results: The 3DMark Sky Diver benchmark test didn’t show much difference between the memory kits, but you do see that the performance does go up slightly with the tighter timings and when we were using a 1T command rate. The highest scores were seen on the HyperX Predator 2400MHz DDR4 memory kit overclocked up to 2666Mhz with 13-13-13-28 1T timings.
