Intel Core i5-9600K vs Intel Core i5-2300

Core i5-9600K vs Core i5-2300 comparison

According to the hardwareDB Benchmark tool, the Core i5-9600K is faster than the Core i5-2300. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-2300 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 i5-2300 that has 4 cores. It also has more threads than the Core i5-2300. These CPUs have different clock speeds. Indeed, the Core i5-9600K has a slightly higher clock speed compared to the Core i5-2300. Also, the Core i5-9600K has a significantly higher turbo speed. Both these chips have an identical TDP (Thermal Design Power). This measures the amount of heat they output and can be used to estimate power consumption.

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. For instance, the Core i5-9600K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
