Chinese outfit 蓝海龙腾 (loosely translates to Blue Sea Dragon) has uploaded a 34-minute video to popular Chinese video sharing platform Bilibili that reportedly shows off the forthcoming Intel Core i5-9600K's stock and 5.1GHz overclocked performance.
Intel unveiled its 9th Generation Intel Core processors last Monday. While Z390 motherboards have already gone up for purchase at U.S. retailers, the 9000-series processors are still on pre-order and won't be released until October 19.
The latest leak gives us a small taste of what we can expect from the Intel Core i5-9600K hexa-core processor in terms of performance gains over the previous model that it's replacing, the Intel Core i5-8600K. Blue Sea Dragon paired its Core i5-9600K ES (engineering sample) chip with an MSI MEG Z390 Godlike motherboard and a 16GB Adata DDR4-2666 memory kit with CL19-19-19-43 timings. The Thermalright Silver Arrow Extreme air cooler took care of the processor's cooling, while an MSI GeForce GTX 1050 Ti was responsible for graphics duty.
Blue Sea Dragon's choice of benchmarks is a lot different from the suite used at Tom's Hardware, so it's hard to make a fair comparison between the Core i5-9600K and our previously recorded benchmark results for the Core i5-8600K. However, we do use the Cinebench R15 benchmark, and Blue Sea Dragon's Core i5-9600K results were surprisingly lower than our Core i5-8600K results. Note, our test platform is similar to theirs. We used a MSI Z370 Gaming Pro Carbon AC motherboard and a 16GB G.Skill FlareX DDR4 memory kit clocked at 2,666MHz for our i5-8600K testing.
Blue Sea Dragon also ran CPU-Z's built-in benchmark. Unfortunately, the Core i5-8600K model wasn't available as an option for comparison. So, Blue Sea Dragon pitched the Core i5-9600K against a Core i7-8700K instead. According to the results, a stock Core i5-9600K is only 4.1 percent and 26.8 percent slower than a stock Core i7-8700K in single-threaded and multi-threaded scenarios, respectively. With the chip overclocked to a little over 5.1GHz with 1.507V, the Core i5-9600K beat the Core i7-8700K by 12.6 percent in the single-thread test, while reducing the multi-thread performance gap from 26.8 percent to 3.4 percent.
