Latest performance benchmarks of the Intel Core i5-9600K unlocked processor have leaked out. The leaks were spotted at a Chinese video streaming portal and revealed details about both stock and overclocked performance of the yet to be released processor.

The benchmarks that have been leaked are not gaming benchmarks but are from CPU-specific workloads but still give us an idea about the overall performance that can be expected from this new processor. Intel has already announced that its 9th Generation Core lineup of processors will be available starting October 19.

About the i5-9600K itself, it’s a 6 core, 6 thread chip with L3 cache memory of 9 MB. It has a base clock speed of 3.7 GHz, 4.6 GHz on boost on a single core. It reaches 4.5 GHz on 2 cores, 4.4 GHz on 4 cores and 4.3 GHz on all 6 cores. It has a TDP rating of 95 W.

The Intel Core i5-9600K will be costing $262 US when it’s available from next week.


The benchmarking process was done on an MSI Z390 MEG Godlike motherboard. It was paired with 16 GB of DDR4 RAM along with a high-end Thermalright Silver Arrow Extreme air cooler. The chip was first tested at stock clock speeds and was able to maintain 4.60 GHz on single-core, and around 4.3 GHz across all cores.

On overclocking, the chip was able to reach speeds up to 5.2 GHz with air cooling and a voltage of 1.507 V. It’s still unclear whether this was a manual overclock or an auto overclock using the built-in BIOS tuner. The Core i5-9600K features the new STIM (Soldered Thermal Interface Material) and even after that, the temperature was exceeding the 90 degree Celsius mark at full load across all cores. This was mostly because of the high voltage. The power consumption of the entire system sits at 240 W in CPU only workloads.

Here are the benchmark scores at stock and overclocked configurations:

Cinebench R15

  • Core i5-9600K @ Stock: 1034 CB
  • Core i5-9600K @ 5.2G: 1207 CB


  • Core i5-9600K @ Stock: 528.8 Single Thread / 2919.1 Multi-Thread
  • Core i5-9600K @ 5.2G: 619 Single Thread / 3579.7 Multi-Thread

X264 HD Benchmark

  • Core i5-9600K @ Stock: 37.55 fps
  • Core i5-9600K @ 5.2G: 43.76 fps
