Intel Core i7-6600U vs Intel Core i3-3220

Core i7-6600U vs Core i3-3220 benchmarks

According to the hardwareDB Benchmark tool, the Core i3-3220 is faster than the Core i7-6600U. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-6600U 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. Our comparison shows that the Core i3-3220 has a slightly higher clock speed compared to the Core i7-6600U. A Core i7-6600U CPU outputs less heat than a Core i3-3220 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 i7-6600U has more threads than cores. Each physical core is split into multiple threads.
