Benchmark Suite

CPU Benchmarks
HEXUS PiFast Our number-crunching benchmark stresses a single core by calculating Pi to 10m places
Cinebench R15 Using Cinebench's multi-CPU render, this cross-platform benchmark stresses all cores
wPrime 2.1.0 Another number-crunching benchmark that stresses all available CPU cores/threads
HandBrake 0.10.5 Free-to-use video encoder that stresses all CPU cores (64-bit)
Memory Benchmarks
AIDA64 v5.80.4021 Benchmark that analyses memory bandwidth and latency
Gaming Benchmarks (GeForce GTX 1080)
3DMark Time Spy Graphics test run using the Time Spy default test
Deus Ex: Mankind Divided 2,560x1,440, ultra settings
Gears of War 4 2,560x1,440, ultra settings
Rise of the Tomb Raider 2,560x1,440, very high quality settings

Miscellaneous Benchmarks
Power Consumption To emulate real-world usage scenarios, we record system-wide mains power draw when idle, when encoding video via HandBrake and while playing Gears of War 4

Notes

We have an early sample of a Core i7-7700K. Though it is marked with the codes you would expect on a retail chip, we found that it had a problem in running memory faster than 2,133MHz. The same set of G.Skill memory operated at 3,000MHz on the Core i7-6700K just fine. We've yet to put the Kaby Lake chip in a Z270 board, mind.
