Intel Core i7-3940XM vs Intel Xeon E5-620

Core i7-3940XM vs Xeon E5-620 comparison

Our benchmark analysis concludes that the Xeon E5-620 performs better 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. With our hardware info, we find that the Core i7-3940XM has a slightly higher clock speed than the Xeon E5-620. Also, the Core i7-3940XM has a significantly higher turbo speed. A Core i7-3940XM CPU outputs less heat than a Xeon E5-620 CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, both these CPUs have the same amount of L2 cache. The Core i7-3940XM also has significantly more L3 cache.

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 i7-3940XM has more threads than cores. Each physical core is split into multiple threads.
