Intel Core i5-8259U vs Intel Core i7-3940XM

Core i5-8259U vs Core i7-3940XM comparison

In our benchmarks, the Core i7-3940XM beats the Core i5-8259U in overall performance. Despite this, the Core i5-8259U has the advantage in our gaming benchmark.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. These CPUs have different clock speeds. Indeed, the Core i7-3940XM has a slightly higher clock speed compared to the Core i5-8259U. Also, the Core i7-3940XM has a slightly higher turbo speed. A Core i5-8259U CPU outputs less heat than a Core i7-3940XM CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The cache sizes of these CPUs are different. Indeed, the Core i5-8259U has significantly more L2 cache than the Core i7-3940XM. Despite this, the Core i7-3940XM has slightly more L3 cache compared to the Core i5-8259U.

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 i5-8259U has more threads than cores. Each physical core is split into multiple threads.
