Core i7-7600U vs Athlon II X4 651 specs and performance
In our benchmarks, the Athlon II X4 651 beats the Core i7-7600U in overall performance. Despite this, the Core i7-7600U 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 Core i7-7600U. Indeed, the Athlon II X4 651 has 4 cores compared to 2 cores found in the Core i7-7600U. But they both have 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 i7-7600U.
Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. Indeed, the Core i7-7600U has more threads than cores. Each physical core is split into multiple threads.
