Athlon II X4 651 vs Xeon L5520 benchmarks

Our benchmark analysis concludes that the Xeon L5520 performs better than the Athlon II X4 651. Despite this, the Athlon II X4 651 has the advantage in our gaming benchmark.

Info from our database shows that they both have the same core count but the Xeon L5520 has more threads. With our hardware info, we find that the Athlon II X4 651 has a slightly higher clock speed than the Xeon L5520. The cache sizes of these CPUs are different. Indeed, the Athlon II X4 651 has significantly more L2 cache than the Xeon L5520

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. For instance, the Athlon II X4 651 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
