Intel Core i7 4790K (Devil’s Canyon) CPU
The Intel Core i7 4790K raises the processor’s clock speed to 4 Gigahertz (500 more than the previous 4770K). The new chip keeps the same architecture, so it keeps the same LGA 1150 socket, but don’t expect dramatic increases.
Being that this new CPU is brand new, your existing motherboard will probably have to be flashed to support the new chip. In my experience, there is always some quirkiness when a motherboard is flashed to support newer chips, so your best bet is to purchase a new motherboard designed for it.
The new CPU integrates Intel’s HD 4600 graphics solution, which provides decent gaming performance, but many enthusiasts will pair this with a good dedicated graphics card.
