We can better compare what are the technical differences between the two processors.
Suggested PSU: We assume that we have An ATX computer case, a high end graphics card, 16GB RAM, a 512GB SSD, a 1TB HDD hard drive, a Blu-Ray drive. We will have to rely on a more powerful power supply if we want to have several graphics cards, several monitors, more memory, etc.
Price: For technical reasons, we cannot currently display a price less than 24 hours, or a real-time price. This is why we prefer for the moment not to show a price. You should refer to the respective online stores for the latest price, as well as availability.
We see that the two processors have an equivalent number of cores, the turbo frequency of Intel Core i7-4790K is bigger, that the PDT of Intel Core i5-8250U is lower. The Intel Core i5-8250U was designed earlier.
