Hong Kong outlet leaks Comet Lake S performance review: i7-10700, i5-10600K, i5-10500, and i5-10400 go up against AMD Ryzen 3700X, 3600X, and Coffee Lake

Hong Kong outlet HKEPC was spotted leaking a performance review for multiple Comet Lake S parts, comparing them to the AMD Ryzen 7 3700X and Ryzen 5 3600X as well as the Coffee Lake i9-9900K, i7-9700K, i7-8700K, and i5-9600K. The tech outlet managed to get their hands on shipping models of the i7-10700K and i5-10400, engineering samples for the i5-10600K and i5-10500, and an OEM B460 motherboard to run them on. 

This particular leak is interesting because we have pictures of the chips and setup being tested, CPU-Z validation, and multiple Comet Lake S benchmarks from a single source.  

HKEPC benchmarked these CPU on AIDA64, Cinebench, Time Spy, Fire Strike, and CPU-Z's own benchmark test.

In Cinebench R15, the i7-10700 trailed the Ryzen 7 3700X in the multi-threaded test with a score of 1974, but matched it in the single-threaded test with 207. Unfortunately, the i5-10600K, i5-10500, and i5-10400 all trailed behind the Ryzen 5 3600X in both the single-threaded and multi-threaded tests.

In 3DMark Time Spy and Fire Strike, the i7-10700 managed to score marginal wins against the Ryzen 7 3700X. However, the i5 parts continued to disappoint, with significantly lower scores than the Ryzen 5 3600X. 

While performance, especially with the i5-10600K and i5-10500, isn't flattering compared to Ryzen, all the Comet Lake S parts tested delivered a good performance improvement over their 9th-gen Coffee Lake predecessors.

These are still solid options for Intel users looking to upgrade. Moreover, since two of tested parts are engineering samples, the shipping Comet Lake S processors may will deliver improvement performance. Unfortunately, because they require LGA 1200 sockets, you'll need to get a new motherboard as well before upgrading to Comet Lake S.
