Core i7-8665U vs Core i5-4670K comparison

According to the hardwareDB Benchmark tool, the Core i7-8665U is faster than the Core i5-4670K. Despite this, the Core i5-4670K has the advantage in our gaming benchmark.

When comparing these CPUs we notice that they have the same number of cores but the Core i7-8665U has more threads. Our comparison shows that the Core i5-4670K 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 i5-4670K 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 i7-8665U has more threads than cores. Each physical core is split into multiple threads.
