Cinebench R15

This particular synthetic benchmark allows for a quick and easy quantification of raw computing power by measuring the time it takes to render a scene consisting of more than 2,000 objects and 300,000 polygons. Given that it supports multiple threads, the benchmark benefits not only from high clock speeds but also the number of cores and threads available. The single-thread test benefits greatly from high clock speeds and cache.

In theory, it is feasible that some processors are better suited for Cinebench’s computation requirements but from our experience this particular benchmark is very well suited for a quick comparison of theoretical maximum processing power.

What surprised us most was the Core i7-8700K’s single-thread performance - it equaled the i7-7700K’s excellent high score. AMD’s Ryzen CPUs fall at least 15% behind in this test.

Even the i5-8400 managed to outperform the Ryzen R7 1800X in this test, albeit only slightly. Its lead on the similarly priced 1700X is more pronounced yet still within acceptable margins. However, the gap between it and both Core i7-X700K models is enormous.

As expected, the i7-8700K outperformed its in-house competitors in the multithread benchmark with ease but was in turn overtaken by the slightly cheaper yet 9% faster Ryzen R7 1700X. Compared to its own predecessor, the i7-7700K, the difference was a staggering 45% - which pretty much reflects the difference in cores between these two.
