Core i5-8279U vs Core i7-6820HK comparison

Our benchmark analysis concludes that the Core i5-8279U performs better than the Core i7-6820HK. Despite this, the Core i7-6820HK has the advantage in our gaming benchmark.

When comparing these CPUs we notice that they have the same number of cores and the same number of threads. With our hardware info, we find that the Core i7-6820HK has a slightly higher clock speed than the Core i5-8279U. Despite this, the Core i5-8279U has a slightly higher turbo speed. A Core i5-8279U CPU outputs less heat than a Core i7-6820HK CPU because of its 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. Indeed, the Core i5-8279U has more threads than cores. Each physical core is split into multiple threads.
