Intel Core i5-8600K

The Core i5-8600K is a 6 core CPU from Intel released in 2017. This chip has a very good overall score with 4307 points in our CPU benchmark. Our gaming benchmark shows that this CPU is a very good processor for gaming, with a score of 6905 points. As for multitasking and heavy workloads, the Core i5-8600K scores 3493 points and 3351 points respectively. Indeed, this is a good rating for very heavy workloads.

The Core i5-8600K has 6 cores and 6 threads. This chip has no simultaneous multithreading support, as it has the same number of cores as threads. This Intel CPU has a clock speed of 3.6 GHz and a turbo speed of 4.3 GHz : a higher clock speed that can be reached when thermals and power delivery allow. This CPU has an unlocked multiplier and allows for overclocking. With adequate cooling and a good power supply, it's possible to run this CPU at a higher clock speed.

As for memory, the Core i5-8600K makes use of DDR4-2666 memory. The faster the memory, the better. Faster memory means that the CPU doesn't have to wait to get the data it needs. It can accommodate a maximum of 128 GiB of memory. Furthermore, this chip can handle up to 2 channels of RAM, a multichannel memory architecture allows for higher data transfer between the CPU and the memory. However, to take advantage of this, you must have enough memory slots filled. Error correcting memory is not supported on this processor.

In terms of cache, the Core i5-8600K has 384 KiB of level 1 cache, 1 MiB of level 2 cache and 9 MiB of level 3 cache. This is a fast memory located close to the processor, which stores copies of frequently used data from main memory.

This CPU has fast connectivity with support for PCI-Express Gen 3. The faster the PCIe link, the better. This allows for better performance with GPUs and NVME SSDs. It has a total of 16 PCIe lanes.

Power and thermals for the Intel Core i5-8600K CPU are a TDP (Thermal Design Power) of 95 watts. This measures the amount of heat the processor produces when running at full load. This isn't a measure of power consumption, but it's a good estimate.
