Intel Core i7-3770K vs Intel Xeon E3-1280 v3

Core i7-3770K vs Xeon E3-1280 v3 specs and performance

In our benchmarks, the Xeon E3-1280 v3 beats the Core i7-3770K in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-3770K in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores and the same number of threads. These CPUs have different clock speeds. Indeed, the Xeon E3-1280 v3 has a slightly higher clock speed compared to the Core i7-3770K. Also, the Xeon E3-1280 v3 has a slightly higher turbo speed. A Core i7-3770K CPU outputs less heat than a Xeon E3-1280 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 i7-3770K has more threads than cores. Each physical core is split into multiple threads.
