Core i7-2700K vs Core i7-3820 specs and performance

In our benchmarks, the Core i7-3820 beats the Core i7-2700K in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-2700K in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. Our comparison shows that the Core i7-3820 has a slightly higher clock speed compared to the Core i7-2700K. Despite this, the Core i7-2700K has a slightly higher turbo speed. A Core i7-2700K CPU outputs less heat than a Core i7-3820 CPU because of its slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. Indeed, the Core i7-2700K has more threads than cores. Each physical core is split into multiple threads.
