CPU and Memory Benchmarks

HEXUS PiFast Our number-crunching benchmark stresses a single core by calculating Pi to 10m places.
Cinebench Using Cinebench's multi-CPU render, this cross-platform benchmark stresses all cores.
Handbrake Free-to-use video encoder that stresses all CPU cores.
AIDA64 Benchmark that analyses memory bandwidth and latency.

Storage Benchmarks

CrystalDiskMark Popular free-to-use storage benchmark, used to gauge read and write performance via M.2 (512GB Toshiba OCZ RD400), SATA (512GB SK hynix Canvas SC300) and USB (512GB SK hynix Canvas SC300).

Gaming Benchmarks

3DMark Run using Fire Strike Ultra 4K UHD test.
Dirt Rally Benchmarked at a 4K UHD resolution with 4xMSAA and ultra quality settings.
Rise of the Tomb Raider Benchmarked at a 4K UHD resolution with DX12 enabled, FXAA and very-high quality settings.

Miscellaneous Benchmarks

Power Consumption Noted at idle, while running the HandBrake video-transcoding test and when playing Dirt Rally.


We've historically had a large number of benchmarks detailing performance between chipsets. Due to the levels of integration in the processor practically all modern motherboards benchmark at the same levels, give or take a per cent or two, so 30-odd graphs showing near-identical performance isn't what you (or we) want to see.

We're running a dozen benchmarks - three each for CPU, memory, storage and gaming - to see if the boards perform at the expected levels. This is more of a sanity check than anything else, and we'll then dabble with a touch of CPU overclocking.

All three of the above-listed boards have been tested from the ground-up using the latest available BIOS and drivers. The two X99 offerings are a natural comparison, and for reference's sake we've also included a high-end Z170 platform.
