Intel Core i7-8665U vs Intel Core i7-4800MQ

Core i7-8665U vs Core i7-4800MQ comparison

According to the hardwareDB Benchmark tool, the Core i7-4800MQ is faster than the Core i7-8665U. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-8665U in all gaming tests too.

Info from our database shows that they both have the same core count and the same number of threads. These CPUs have different clock speeds. Indeed, the Core i7-4800MQ has a slightly higher clock speed compared to the Core i7-8665U. Despite this, the Core i7-8665U has a slightly higher turbo speed. A Core i7-8665U CPU outputs less heat than a Core i7-4800MQ 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 i7-8665U has more threads than cores. Each physical core is split into multiple threads.
