Intel Core i7-6500U vs Intel Core i7-4558U

Core i7-6500U vs Core i7-4558U benchmarks

In our benchmarks, the Core i7-6500U beats the Core i7-4558U in overall performance. Despite this, the Core i7-4558U has the advantage in our gaming benchmark.

When comparing these CPUs we notice that they have the same number of cores and the same number of threads. Our comparison shows that the Core i7-4558U has a slightly higher clock speed compared to the Core i7-6500U. Also, the Core i7-4558U has a slightly higher turbo speed. A Core i7-6500U CPU outputs less heat than a Core i7-4558U CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

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 i7-6500U has more threads than cores. Each physical core is split into multiple threads.
