Core i7-8665U vs Xeon E3-1275L v3 specs and performance
Our benchmark analysis concludes that the Xeon E3-1275L v3 performs better than the Core i7-8665U. Despite this, the Core i7-8665U has the advantage in our gaming benchmark.
Our spec comparison shows that they have an identical amount of cores and the same number of threads. Our comparison shows that the Xeon E3-1275L v3 has a slightly 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 Xeon E3-1275L v3 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.
