Core i7-4558U vs FX-770K benchmarks

Our benchmark analysis concludes that the FX-770K performs better than the Core i7-4558U. Despite this, the Core i7-4558U 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. Our comparison shows that the FX-770K has a slightly higher clock speed compared to the Core i7-4558U. Also, the FX-770K has a slightly higher turbo speed. A Core i7-4558U CPU outputs less heat than a FX-770K CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. Indeed, the Core i7-4558U has more threads than cores. Each physical core is split into multiple threads.
