Maxon Cinebench R15
CINEBENCH R15 is a cross-platform testing suite that measures hardware performance and is the de facto standard benchmarking tool for leading companies and trade journals for conducting real-world hardware performance tests. With the new Release 15, systems with up to 256 threads can be tested.
CINEBENCH is available for both Windows and OS X and is used by almost all hardware manufacturers and trade journals for comparing CPUs and graphics cards.
Unsurprisingly, the six cores running at 4.4GHz in the PC Specialist system provide considerably more rendering performance than the four cores running at 3.5GHz in our ASRock's Xeon E3 processor.
A frequency-enhanced Skylake Core i7 could improve on this, but the six- and eight-core Haswell-E Core i7 processors will always have the upper hand here, because cores are king for rendering.
The Maxon Cinebench R15 OpenGL test is a little sensitive to CPU clock speed than most professional graphics tests, so our ASRock setup has fallen a little behind here.
But a frequency-enhanced Skylake Core i7 could go further, as these have a little more headroom than the Haswell E Core i7s, and can hit as much as 4.8GHz very stably.
