Difference Between i5 and i7


Main Difference

i5 and i7 are the two important processors of Intel that are regarded as one of the best and faster processors in the world of IT. Although both are the 5th generation Intel Core processors but there are lot of differences between i5 and i7. The main difference between i5 and i7 is that i7 core processors cache and clock speed is more than it.

What is i5?

Intel Core i5 processors is the 5th generation technology of Intel that empower new innovations and features like Intel RealSense technology. Intel RealSense technology is known for advanced features like gesture control, 3D capture and edit, and innovative and advanced photo and video capabilities to computing device. i5 gives the options of stunning visuals, built-in security, and an automatic burst of speed when it comes to Intel Turbo Boost Technology. Intel Core i5 processors are for all computing devices like 2 in 1s, tablets, laptops and desktops.


What is i7?

i7 is the latest Intel microarchitecture on the 14 nm manufacturing process delivers performance advancements that includes vastly improved graphics, battery life, and security. Based on the latest features of Intel Hyper-Threading Technology it allows the each processor core to work on two tasks at the same time for smoother multitasking, and Intel Iris graphics for stunning 3D visuals and faster, more advanced video and photo editing, the 5th generation Intel Core i7 processor delivers top-of-the-line performance for the most demanding tasks. Intel Core i7 processors are for all computing devices like 2 in 1s, tablets, laptops and desktops.
