Intel Core i7-2600K vs Intel Core 2 Quad Q9400

Core i7-2600K vs Core 2 Quad Q9400 specs and performance

According to the hardwareDB Benchmark tool, the Core i7-2600K is faster than the Core 2 Quad Q9400. Furthermore, our gaming benchmark shows that it also outperforms the Core 2 Quad Q9400 in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores but the Core i7-2600K has more threads. With our hardware info, we find that the Core i7-2600K has a slightly higher clock speed than the Core 2 Quad Q9400. 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.

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. Indeed, the Core i7-2600K has more threads than cores. Each physical core is split into multiple threads.
