Intel Core 2 Quad Q9400 vs Intel Core 2 Quad Q9550

Core 2 Quad Q9400 vs Core 2 Quad Q9550 benchmarks

According to the hardwareDB Benchmark tool, the Core 2 Quad Q9550 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.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. These CPUs have different clock speeds. Indeed, the Core 2 Quad Q9550 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 data shows that both these CPUs have same sized L2 caches

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. For instance, the Core 2 Quad Q9400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
