Intel Core i3-9300 vs Intel Core i5-9600K

Core i3-9300 vs Core i5-9600K specs and performance

Our benchmark analysis concludes that the Core i5-9600K performs better than the Core i3-9300. Furthermore, our gaming benchmark shows that it also outperforms the Core i3-9300 in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i5-9600K has significantly more cores with 6 cores compared to the Core i3-9300 that has 4 cores. It also has more threads than the Core i3-9300. According to our data, the Core i3-9300 and Core i5-9600K have the same clock speed. Despite this, the Core i5-9600K has a slightly higher turbo speed. A Core i3-9300 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 i3-9300. The Core i5-9600K also has slightly more L3 cache.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. For instance, the Core i3-9300 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
