Intel Core i5-3380M vs Intel Core 2 Quad Q9400

Core i5-3380M vs Core 2 Quad Q9400 benchmarks

Our benchmark analysis concludes that the Core 2 Quad Q9400 performs better than the Core i5-3380M. Despite this, the Core i5-3380M has the advantage in our gaming benchmark.

In terms of the number of cores of each of these CPUs, the Core 2 Quad Q9400 has significantly more cores than the Core i5-3380M. Indeed, the Core 2 Quad Q9400 has 4 cores compared to 2 cores found in the Core i5-3380M. But they both have the same number of threads. Our comparison shows that the Core i5-3380M has a slightly higher clock speed compared to the Core 2 Quad Q9400. A Core i5-3380M 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.

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. Indeed, the Core i5-3380M has more threads than cores. Each physical core is split into multiple threads.
