Core i5-4690K vs Core i7-3940XM specs and performance

According to the hardwareDB Benchmark tool, the Core i7-3940XM is faster than the Core i5-4690K. Despite this, the Core i5-4690K has the advantage in our gaming benchmark.

When comparing these CPUs we notice that they have the same number of cores but the Core i7-3940XM has more threads. With our hardware info, we find that the Core i5-4690K has a slightly higher clock speed than the Core i7-3940XM. Furthermore, both these CPUs have identical turbo speeds. The Core i7-3940XM outputs less heat than Core i5-4690K thanks to a 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. For instance, the Core i5-4690K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
