Core i7-8565U vs Core i7-4900MQ specs and performance
Our benchmark analysis concludes that the Core i7-4900MQ performs better than the Core i7-8565U. Despite this, the Core i7-8565U has the advantage in our gaming benchmark.
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 i7-4900MQ has a significantly higher clock speed compared to the Core i7-8565U. Despite this, the Core i7-8565U has a slightly higher turbo speed. A Core i7-8565U CPU outputs less heat than a Core i7-4900MQ CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. When comparing cache sizes, these CPUs have an identical amount of L2 cache and L3 cache.
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 i7-8565U has more threads than cores. Each physical core is split into multiple threads.
