Xeon E5-2640 vs Core i7-3820 specs and performance

Our benchmark analysis concludes that the Xeon E5-2640 performs better than the Core i7-3820. Despite this, the Core i7-3820 has the advantage in our gaming benchmark.

In terms of the number of cores of each of these CPUs, the Xeon E5-2640 has significantly more cores than the Core i7-3820. Indeed, the Xeon E5-2640 has 6 cores compared to 4 cores found in the Core i7-3820. It also has more threads than the Core i7-3820. Our comparison shows that the Core i7-3820 has a significantly higher clock speed compared to the Xeon E5-2640. Also, the Core i7-3820 has a slightly higher turbo speed. A Xeon E5-2640 CPU outputs less heat than a Core i7-3820 CPU because of its slightly 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 E5-2640 has more threads than cores. Each physical core is split into multiple threads.
