Early Core i7-8700K benchmarks show 42% performance boost in multi-threaded software

Asian tech site Expreview did it again and managed to get its hands on a sample of the Intel Core i7-8700K processor to publish an early review well before the October 5 NDA expiry. The site compared the 8700K with the 7700K and also did some tests with both processors clocked at 4.5GHz to measure if there's any IPC gain.

Single-threaded performance is somewhat of a mixed bag, its faster in some test cases but in other scenarios the difference is minimal or even negative. With both chips clocked at the same frequency, there do seem to be some IPC gains as Coffee Lake delivers more per-clock performance than Kaby Lake. But there may still be some bugs as the tests were performed on an engineering sample rather than the final retail product.

In multi-threaded benchmarks the 8700K really shines, this new model has two more cores than its predecessor and this helps a lot to achieve a 42 performance boost in multi-threaded apps. No temperature or power draw measurements yet, so still too early to draw firm conclusions.
