Core i7-6600U vs Core i7-8565U comparison
In our benchmarks, the Core i7-8565U beats the Core i7-6600U in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-6600U in all gaming tests too.
In terms of the number of cores of each of these CPUs, the Core i7-8565U has significantly more cores than the Core i7-6600U. Indeed, the Core i7-8565U has 4 cores compared to 2 cores found in the Core i7-6600U. It also has more threads than the Core i7-6600U. Our comparison shows that the Core i7-6600U has a significantly higher clock speed compared to the Core i7-8565U. Despite this, the Core i7-8565U has a slightly higher turbo speed. Both these chips have an identical TDP (Thermal Design Power). 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.
