Intel Core i7-3820 vs Intel Core i7-4770S

Core i7-3820 vs Core i7-4770S benchmarks

In our benchmarks, the Core i7-3820 beats the Core i7-4770S in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-4770S 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 Core i7-3820 has a slightly higher clock speed compared to the Core i7-4770S. Despite this, the Core i7-4770S has a slightly higher turbo speed. The Core i7-4770S outputs less heat than Core i7-3820 thanks to a 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 i7-3820 has more threads than cores. Each physical core is split into multiple threads.
