Core i7-8665U vs Core i5-6402P benchmarks

In our benchmarks, the Core i7-8665U beats the Core i5-6402P in overall performance. Despite this, the Core i5-6402P has the advantage in our gaming benchmark.

Info from our database shows that they both have the same core count but the Core i7-8665U has more threads. With our hardware info, we find that the Core i5-6402P has a significantly higher clock speed than 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 i5-6402P 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 i7-8665U has more threads than cores. Each physical core is split into multiple threads.
