Core i5-2500K vs Core i9-12900T specs and performance

Our benchmark analysis concludes that the Core i9-12900T performs better than the Core i5-2500K. Despite this, the Core i5-2500K has the advantage in our gaming benchmark.

With info from our database, we find that the Core i9-12900T has significantly more cores with 16 cores whereas the Core i5-2500K has 4 cores. It also has more threads than the Core i5-2500K. Our comparison shows that the Core i5-2500K has a significantly higher clock speed compared to the Core i9-12900T. Despite this, the Core i9-12900T has a slightly higher turbo speed. The Core i9-12900T outputs less heat than Core i5-2500K thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

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 i5-2500K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
