Core i7-3820 vs Xeon E5-1620 v3 comparison

According to the hardwareDB Benchmark tool, the Xeon E5-1620 v3 is faster than the Core i7-3820. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-3820 in all gaming tests too.

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 E5-1620 v3. Also, the Core i7-3820 has a slightly higher turbo speed. A Core i7-3820 CPU outputs less heat than a Xeon E5-1620 v3 CPU because of its slightly 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.
