Intel Core 2 Quad Q9400 vs Intel Core 2 Quad Q9650

Core 2 Quad Q9400 vs Core 2 Quad Q9650 comparison

In our benchmarks, the Core 2 Quad Q9650 beats the Core 2 Quad Q9400 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core 2 Quad Q9400 in all gaming tests too.

Info from our database shows that they both have the same core count and the same number of threads. These CPUs have different clock speeds. Indeed, the Core 2 Quad Q9650 has a slightly higher clock speed compared to 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 info from our database shows that the Core 2 Quad Q9650 has more L2 cache than the Core 2 Quad Q9400

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.
