Core i7-8550U vs A6-6400K comparison

Our benchmark analysis concludes that the Core i7-8550U performs better than the A6-6400K. Furthermore, our gaming benchmark shows that it also outperforms the A6-6400K in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i7-8550U has significantly more cores with 4 cores compared to the A6-6400K that has 1 cores. It also has more threads than the A6-6400K. With our hardware info, we find that the A6-6400K has a significantly higher clock speed than the Core i7-8550U. Also, the A6-6400K has a slightly higher turbo speed. A Core i7-8550U CPU outputs less heat than a A6-6400K 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

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. Indeed, the Core i7-8550U has more threads than cores. Each physical core is split into multiple threads.
