Leaked Benchmarks Pit Intel Core i5-8600K vs. i7-7700K

Early leaks show the Intel Coffee Lake i7-8700K processor doing well against the i7-7700K and the i7-7800X HEDT processor a few days ago. Now another leak from PCOnline in China show the Core i5-8600K going toe-to-toe against the Core i7-7700K.

Intel Core i5-8600K vs. i7-7700K Specifications

Unusual for an i5, the Core i5-8600K actually has six cores and six threads. This is the first time a Core i5 came in six cores. The i7-7700K on the other hand only has four cores. However, it has HyperThreading with eight cores.

There is also a discrepancy in speed since the i5-8600K runs slower with a 3.60GHz base and 4.30GHz Turbo. The 7th generation Intel Core i7-7700K on the other hand has a 4.2GHz base frequency and 4.5GHz Turbo.

In terms of cache size, the new i5-8600K has a 1MB advantage at 9MB vs 8MB, and has a slightly higher TDP as well at 95W vs 91W.

System Benchmarks

Cinebench R15 shows the i7-7700K leading in both multi-core and single-core benchmark.
