Intel Core i7-3940XM vs Intel Xeon E3-1220 v5

Core i7-3940XM vs Xeon E3-1220 v5 specs and performance

According to the hardwareDB Benchmark tool, the Core i7-3940XM is faster than the Xeon E3-1220 v5. Despite this, the Xeon E3-1220 v5 has the advantage in our gaming benchmark.

Info from our database shows that they both have the same core count but the Core i7-3940XM has more threads. These CPUs have different clock speeds. Indeed, the Core i7-3940XM has a slightly higher clock speed compared to the Xeon E3-1220 v5. Also, the Core i7-3940XM has a slightly higher turbo speed. A Core i7-3940XM CPU outputs less heat than a Xeon E3-1220 v5 CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The cache sizes of these CPUs are different. Indeed, the Xeon E3-1220 v5 has significantly more L2 cache than the Core i7-3940XM. However, both these chips have the same amount of L3 cache.

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