Core i5-6440HQ vs Core i5-8350U specs and performance

In our benchmarks, the Core i5-8350U beats the Core i5-6440HQ in overall performance. Despite this, the Core i5-6440HQ has the advantage in our gaming benchmark.

Info from our database shows that they both have the same core count but the Core i5-8350U has more threads. These CPUs have different clock speeds. Indeed, the Core i5-6440HQ has a significantly higher clock speed compared to the Core i5-8350U. Despite this, the Core i5-8350U has a slightly higher turbo speed. The Core i5-8350U outputs less heat than Core i5-6440HQ thanks to a 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. For instance, the Core i5-6440HQ has the same number of threads as cores. This means the the CPU does not support hyperthreading.
