Intel Xeon E5-1620 vs Intel Core i7-3940XM

Xeon E5-1620 vs Core i7-3940XM comparison

According to the hardwareDB Benchmark tool, the Xeon E5-1620 is faster than the Core i7-3940XM. Despite this, the Core i7-3940XM has the advantage in our gaming benchmark.

When comparing these CPUs we notice that they have the same number of cores and the same number of threads. These CPUs have different clock speeds. Indeed, the Xeon E5-1620 has a slightly higher clock speed compared to the Core i7-3940XM. Despite this, the Core i7-3940XM has a slightly higher turbo speed. The Core i7-3940XM outputs less heat than Xeon E5-1620 thanks to a 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 Xeon E5-1620 has more threads than cores. Each physical core is split into multiple threads.
