Core i7-3820QM vs Xeon E3-1220 v3 specs and performance

According to the hardwareDB Benchmark tool, the Core i7-3820QM is faster than the Xeon E3-1220 v3. Despite this, the Xeon E3-1220 v3 has the advantage in our gaming benchmark.

Our spec comparison shows that they have an identical amount of cores but the Core i7-3820QM has more threads. These CPUs have different clock speeds. Indeed, the Xeon E3-1220 v3 has a slightly higher clock speed compared to the Core i7-3820QM. Despite this, the Core i7-3820QM has a slightly higher turbo speed. A Core i7-3820QM CPU outputs less heat than a Xeon E3-1220 v3 CPU because of its 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 i7-3820QM has more threads than cores. Each physical core is split into multiple threads.
