Athlon II X4 651 vs Core 2 Quad Q9505 comparison
Our benchmark analysis concludes that the Athlon II X4 651 performs better than the Core 2 Quad Q9505. Furthermore, our gaming benchmark shows that it also outperforms the Core 2 Quad Q9505 in all gaming tests too.
Our spec comparison shows that they have an identical amount of cores and the same number of threads. These CPUs have different clock speeds. Indeed, the Athlon II X4 651 has a slightly higher clock speed compared to the Core 2 Quad Q9505. The info from our database shows that the Core 2 Quad Q9505 has more L2 cache than the Athlon II X4 651
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 Athlon II X4 651 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
