Core i7-8665U vs Core i5-4570S benchmarks

According to the hardwareDB Benchmark tool, the Core i7-8665U is faster than the Core i5-4570S. Despite this, the Core i5-4570S has the advantage in our gaming benchmark.

Our spec comparison shows that they have an identical amount of cores but the Core i7-8665U has more threads. Our comparison shows that the Core i5-4570S has a significantly higher clock speed compared to the Core i7-8665U. Despite this, the Core i7-8665U has a slightly higher turbo speed. A Core i7-8665U CPU outputs less heat than a Core i5-4570S 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 i7-8665U has more threads than cores. Each physical core is split into multiple threads.
