Intel Celeron N4120 vs Intel Core 2 Quad Q9400

Celeron N4120 vs Core 2 Quad Q9400 comparison

Our benchmark analysis concludes that the Core 2 Quad Q9400 performs better than the Celeron N4120. Furthermore, our gaming benchmark shows that it also outperforms the Celeron N4120 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 Q9400 has a significantly higher clock speed compared to the Celeron N4120. A Celeron N4120 CPU outputs less heat than a Core 2 Quad Q9400 CPU because of its significantly lower TDP. 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 Celeron N4120 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
