AMD Athlon II X4 651 vs AMD Athlon X4 870K

Athlon II X4 651 vs Athlon X4 870K benchmarks

Our benchmark analysis concludes that the Athlon II X4 651 performs better than the Athlon X4 870K. Despite this, the Athlon X4 870K has the advantage in our gaming benchmark.

In terms of the number of cores of each of these CPUs, the Athlon II X4 651 has significantly more cores than the Athlon X4 870K. Indeed, the Athlon II X4 651 has 4 cores compared to 2 cores found in the Athlon X4 870K. But they both have the same number of threads. With our hardware info, we find that the Athlon X4 870K has a slightly higher clock speed than the Athlon II X4 651. The data shows that both these CPUs have same sized L2 caches

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.
