Intel Core i7-8665U vs Intel Xeon E5-1603 v3

Core i7-8665U vs Xeon E5-1603 v3 specs and performance

In our benchmarks, the Core i7-8665U beats the Xeon E5-1603 v3 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E5-1603 v3 in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores but the Core i7-8665U has more threads. A Core i7-8665U CPU outputs less heat than a Xeon E5-1603 v3 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.
