Intel Core i5-2500K

The Core i5-2500K is a 4 core CPU from Intel released in 2011. This chip has an average overall score at 23% in our CPU benchmark. Our gaming benchmark shows that this CPU is a very good processor for gaming, with a score of 41%. As for multitasking and heavy workloads, the Core i5-2500K scores 17% and 17% respectively. Indeed, this is an average rating for very heavy workloads.

The Core i5-2500K has 4 cores and 4 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 3.3 GHz and a turbo speed of 3.7 GHz : a higher clock speed that can be reached when thermals and power delivery allow.

As for memory, the Core i5-2500K makes use of DDR3-1066 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 32 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.

This CPU has fast connectivity with support for PCI-Express Gen 2. 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 i5-2500K 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 good estimate.
