Intel Celeron G3930 vs Intel Core 2 Quad Q9400

Celeron G3930 vs Core 2 Quad Q9400 comparison

Our benchmark analysis concludes that the Core 2 Quad Q9400 performs better than the Celeron G3930. Despite this, the Celeron G3930 has the advantage in our gaming benchmark.

When comparing core counts for these CPUs, we notice that the Core 2 Quad Q9400 has significantly more cores with 4 cores compared to the Celeron G3930 that has 2 cores. It also has more threads than the Celeron G3930. Our comparison shows that the Celeron G3930 has a slightly higher clock speed compared to the Core 2 Quad Q9400. A Celeron G3930 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. The cache sizes of these CPUs are different. Indeed, the Core 2 Quad Q9400 has significantly more L2 cache than the Celeron G3930

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 G3930 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
