Intel Core 2 Quad Q9400 vs AMD Athlon X4 750K

Core 2 Quad Q9400 vs Athlon X4 750K specs and performance

In our benchmarks, the Athlon X4 750K beats the Core 2 Quad Q9400 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core 2 Quad Q9400 in all gaming tests too.

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 Athlon X4 750K that has 2 cores. But they both have the same number of threads. Our comparison shows that the Athlon X4 750K 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 X4 750K

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.
