Core i7-3820 vs Xeon E3-1240 v3 comparison

Our benchmark analysis concludes that the Xeon E3-1240 v3 performs better than the Core i7-3820. Despite this, the Core i7-3820 has the advantage in our gaming benchmark.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. With our hardware info, we find that the Core i7-3820 has a slightly higher clock speed than the Xeon E3-1240 v3. Furthermore, both these CPUs have identical turbo speeds. The Xeon E3-1240 v3 outputs less heat than Core i7-3820 thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

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 i7-3820 has more threads than cores. Each physical core is split into multiple threads.
