Intel Core i5-9600K 9th Gen Core Benchmarks Leak, Hits 5.2GHz On Air

Intel CPU Die
Much of the attention over Intel's recently launched 9th generation Core lineup has been paid to the Core i9-9900K, the flagship CPU in the new mainstream lineup, and Intel's first 8-core/16-thread part. However, there are two other 9th gen chips: Core i7-9700K and Core i5-9600K. Review embargoes exist for all three, though benchmarks have leaked out showing how the Core i5-9600K performs at stock settings, and when overclocked to 5.2GHz.

Like the two other 9th gen parts, the Core i5-9600K is built on a refined 14nm++ manufacturing process. It's the lone 6-core part in the new lineup and lacks Hyper Threading support. It has a 3.7GHz base clock and 4.6GHz boost clock, and 9MB of L3 cache. Perhaps importantly for overclockers, it also features a solder TIM (thermal interface material) underneath the IHS (integrated heatspreader) instead of the lower quality grease that Intel switched to a few generations ago.

A video in China purportedly shows the Core i5-9600K being tested in an MSI Z390 MEG Godlike motherboard with 16GB of DDR4 memory and a rather large air cooler, Thermalright's Silver Arrow Extreme. Under that setup, the Core i5-9600K was able to run at 5.2GHz, albeit with a high 1.507V setting.

The testers did not run any gaming benchmarks, so those will have to wait for another day. However, they did run a few CPU intensive benchmarks. In Cinebench R15, the Core i5-9600K scored 1,034 CB at stock settings, and 1,207 CB when overclocked. That's about in line with a Core i5-8400, a 6-core/6-thread part clocked at 2.8GHz to 4GHz, which in our tests scores 953 at stock settings.

Cinebench R15 is a benchmark that scales well with additional cores and threads. As such, the lack of Hyper Threading support on the Core i5-9600K appears to hold it back compared to processors like the Core i7-8700K, which we benchmarked at 1,425 CB.

For the moment, the Core i5-9600K is the least expensive 9th gen chip. Intel set the price at $262 for 1,000-unit trays (bulk orders, basically), and it's available to pre-order for $279.99. That's a $75 premium over the previous generation Core i5-8400, which sells for $204.99.
