Core i7-6660U vs Xeon E3-1240L v3 benchmarks
In our benchmarks, the Xeon E3-1240L v3 beats the Core i7-6660U in overall performance. Despite this, the Core i7-6660U has the advantage in our gaming benchmark.
In terms of the number of cores of each of these CPUs, the Xeon E3-1240L v3 has significantly more cores than the Core i7-6660U. Indeed the Xeon E3-1240L v3 has 2 compared to 4 found in the Core i7-6660U. It also has more threads than the Core i7-6660U. These CPUs have different clock speeds. Indeed, the Core i7-6660U has a slightly higher clock speed compared to the Xeon E3-1240L v3. Also, the Core i7-6660U has a slightly higher turbo speed. A Core i7-6660U CPU outputs less heat than a Xeon E3-1240L v3 CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.
Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. Indeed, the Core i7-6660U has more threads than cores. Each physical core is split into multiple threads.
