Core i5-6600T vs Core i7-8665U specs and performance

According to the hardwareDB Benchmark tool, the Core i7-8665U is faster than the Core i5-6600T. Despite this, the Core i5-6600T 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 i5-6600T has a slightly higher clock speed than the Core i7-8665U. Despite this, the Core i7-8665U has a slightly higher turbo speed. The Core i7-8665U outputs less heat than Core i5-6600T thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. For instance, the Core i5-6600T has the same number of threads as cores. This means the the CPU does not support hyperthreading.
