Intel Core i5-750 vs Intel Core 2 Quad Q9400

Core i5-750 vs Core 2 Quad Q9400 specs and performance

Our benchmark analysis concludes that the Core i5-750 performs better 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 and the same number of threads. Both the Core i5-750 and Core 2 Quad Q9400 have the same clock speed. 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.

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. For instance, the Core i5-750 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
