Intel's Core i5-14600K CPU was benchmarked mid-September, courtesy of ECSM getting their hands on some engineering samples—these examples were put under strain through Cinebench R23, Cinebench 2024, and CPU-Z suites. The ever reliable Benchleaks has kept track of mid-range Raptor Lake Refresh processor leaks—late last week they pointed to a new entry on Geekbench Browser. PC hardware news outlets have reported that reviewers now possess pre-release silicon, so we should be expecting an increase in leaky activity over the next fortnight—Intel's official embargo will likely be lifted on the 14th Gen Core launch day (October 17). Team Blue's Core i5-14600K has popped up a few times via Geekbench 6.2 results—TestKT's build was running on stock settings, and hit a maximum clock of 5.3 GHz (K and KF variants), with an ASUS Z790 TUF PLUS motherboard accompanied by 32 GB of DDR5-5200 memory, while an anonymous bencher fielded a system sporting a Gigabyte Z790 AORUS Master X mainboard and 48 GB DDR5-7600 RAM. The latter had some overclocking on the go; Geekbench 6.2 stats reported clocks reaching 5.7 GHz on the Core i5-14600K.

TestKT's stock 14600K achieved scores of 2819 in single-threaded, and 16666 multi-threaded. Their 14600KF scored 2779 and 16707 (respectively) on the same ASUS platform. The unnamed Gigabyte system wielder tallied 2861 (SC) and 17974 (MC) on an overclocked 14600K. VideoCardz noted that: "this represents a minor increase in single-core performance and approximately an 8% improvement in multi-threaded performance." They brought in a previously leaked higher-end CPU for comparative purposes: "Since the latter score is using the same (Gigabyte) system as in the Core i7-14700KF Geekbench leak, we can now conclude that Core i7 CPU will be at least 8% and 18% faster respectively than the Core i5 SKU. That's, of course, assuming both scores were using OC settings." We will have to wait until the publication of official reviews to find out whether these figures were produced on finalized silicon.VideoCardz has compiled leaked 14th Gen Core SKU data:
