Core i3-10300 vs Core i5-9600K benchmarks

According to the hardwareDB Benchmark tool, the Core i5-9600K is faster than the Core i3-10300. Furthermore, our gaming benchmark shows that it also outperforms the Core i3-10300 in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i5-9600K has significantly more cores than the Core i3-10300. Indeed, the Core i5-9600K has 6 cores compared to 4 cores found in the Core i3-10300. Despite this, the Core i3-10300 has more threads than the Core i5-9600K. According to our data, the Core i3-10300 and Core i5-9600K have the same clock speed. Despite this, the Core i5-9600K has a slightly higher turbo speed. A Core i3-10300 CPU outputs less heat than a Core i5-9600K CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, the Core i5-9600K has significantly more L2 cache when compared to the Core i3-10300. The Core i5-9600K also has slightly more L3 cache.

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. Indeed, the Core i3-10300 has more threads than cores. Each physical core is split into multiple threads.
