Intel Core i7-3930K vs Intel Xeon E3-1240 v3

Core i7-3930K vs Xeon E3-1240 v3 specs and performance

In our benchmarks, the Core i7-3930K beats the Xeon E3-1240 v3 in overall performance. Despite this, the Xeon E3-1240 v3 has the advantage in our gaming benchmark.

When comparing core counts for these CPUs, we notice that the Core i7-3930K has significantly more cores with 6 cores compared to the Xeon E3-1240 v3 that has 4 cores. It also has more threads than the Xeon E3-1240 v3. These CPUs have different clock speeds. Indeed, the Xeon E3-1240 v3 has a slightly higher clock speed compared to the Core i7-3930K. Furthermore, both these CPUs have identical turbo speeds. The Xeon E3-1240 v3 outputs less heat than Core i7-3930K 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 Core i7-3930K has more threads than cores. Each physical core is split into multiple threads.
