Core i7-8665U vs Core i7-3820 comparison

According to the hardwareDB Benchmark tool, the Core i7-3820 is faster than the Core i7-8665U. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-8665U in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. Our comparison shows that the Core i7-3820 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 i7-3820 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.
