Intel Core i5-5257U vs Intel Core i7-5600U

Core i5-5257U vs Core i7-5600U specs and performance

In our benchmarks, the Core i5-5257U beats the Core i7-5600U in overall performance. Despite this, the Core i7-5600U has the advantage in our gaming benchmark.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. Our comparison shows that the Core i5-5257U has a slightly higher clock speed compared to the Core i7-5600U. Despite this, the Core i7-5600U has a slightly higher turbo speed. The Core i7-5600U outputs less heat than Core i5-5257U thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, both these CPUs have the same amount of L2 cache. The Core i7-5600U also has slightly more L3 cache.

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 i5-5257U has more threads than cores. Each physical core is split into multiple threads.
