Indeed, the Core 2 Quad Q9400 has 4 cores compared to 2 cores found in the FX-770K. But they both have the same number of threads. These CPUs have different clock speeds. Indeed, the FX-770K has a slightly higher clock speed compared to the Core 2 Quad Q9400. The FX-770K outputs less heat than Core 2 Quad Q9400 thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The info from our database shows that the Core 2 Quad Q9400 has more L2 cache than the FX-770K

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 2 Quad Q9400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
