Core i7-3820QM vs Xeon E3-1220 comparison

In our benchmarks, the Core i7-3820QM beats the Xeon E3-1220 in overall performance. Despite this, the Xeon E3-1220 has the advantage in our gaming benchmark.

Info from our database shows that they both have the same core count but the Core i7-3820QM has more threads. Our comparison shows that the Xeon E3-1220 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 CPU because of its 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 i7-3820QM has more threads than cores. Each physical core is split into multiple threads.
