Tests show that CPU Core i7-8700K faster Core i7-7700K almost half

Yesterday we got acquainted with the performance and capabilities of dispersal of the processor Core i9-7980XE. In addition, yesterday was announced, and CPU Coffee Lake.

They will be on sale on 5 October, but this has not prevented our Chinese colleagues to get the Intel Core i7-8700K and to conduct its testing. Unlike most of these «false starts», in this case, the test is quite large, including many different. Although the opponent only two: Core i7-7700K and Core i7-7800X. Last, we recall, refers to a family of Skylake-X, has the same six cores, and a beginner, he is a four-channel memory controller, but lower frequency (3.5 to 4.0 GHz). Unfortunately, among the opponents was not the AMD.

As you can see, the final multi-threaded performance Core i7-8700K almost one and a half times higher than the Core i7-7700K and not very far behind the Core i7-7800X. Single-threaded performance, can not be considered, as it is almost the same everywhere.

But it is worth noting that if we discard the synthetic tests, it turns out that Core i7-7800X in most cases loses to the Core i7-8700K. And actually there is nothing surprising, because its frequency is significantly lower. Recall that in our tests, the Core i7-7800X inferior Ryzen 7 1800X. Can we assume that the Core i7-8700K will compete with Ryzen 7 1700 or 1700X.

Note also that in the gaming tests, all three processors are almost identical, which suggests that most modern games (assuming graphics card performance) need is high frequency Quad core CPU Intel.

Tests of all three processors at same frequency (4.5 GHz) showed almost the same result, except that the Core i7-7800X is better made, as it was originally with a low frequency of the Trinity.
