Core i7-6500U vs Core i5-5257U benchmarks

In our benchmarks, the Core i5-5257U beats the Core i7-6500U in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-6500U in all gaming tests too.

Info from our database shows that they both have the same core count and the same number of threads. With our hardware info, we find that the Core i5-5257U has a slightly higher clock speed than the Core i7-6500U. In addition, both chips have the same turbo speed. A Core i7-6500U CPU outputs less heat than a Core i5-5257U CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

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