Intel Core 2 Quad Q9400 vs AMD Athlon II X3 450

Core 2 Quad Q9400 vs Athlon II X3 450 specs and performance

Our benchmark analysis concludes that the Core 2 Quad Q9400 performs better than the Athlon II X3 450. Despite this, the Athlon II X3 450 has the advantage in our gaming benchmark.

When comparing core counts for these CPUs, we notice that the Core 2 Quad Q9400 has slightly more cores with 4 cores compared to the Athlon II X3 450 that has 3 cores. It also has more threads than the Athlon II X3 450. Our comparison shows that the Athlon II X3 450 has a slightly higher clock speed compared to the Core 2 Quad Q9400. The cache sizes of these CPUs are different. Indeed, the Core 2 Quad Q9400 has significantly more L2 cache than the Athlon II X3 450

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. For instance, the Core 2 Quad Q9400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
