Intel - Haswell processors

Computers play a very important role not only for browsing the Internet, creating different documents or engineering systems. They need to perform fast in advanced protection, automation and control related applications that may impose high-speed computational and graphics support requirements.

Intel recently released under the code name Haswell the fourth generation of its Core i-series processors found in nearly every laptop, desktop, and (Windows) tablet on the market. The last generation, code-named "Ivy Bridge," was released mid-2012.

The newest CPUs come in a variety of types: desktop-based quad-core processors, dual-core mainstream processors, lower-power longer-battery-life ultrabook processors, and processors aimed specifically at tablets.

They are still all Core i3(slowest), i5, and i7 (fastest) processors, with a variety of speeds and types for each. To know if the computer that you have is using "Haswell" you need to make sure that the first number after the "i7" or "i5" is a 4, as in "Core i7-4650U." If it were an older third-gen processor, that four-digit number would start with a 3.
Intel has also created four classes of mobile processor based on PC type: "H" for high-end quad-core processors, "M" for mainstream quad-core and dual-core laptops and some desktops, "U" for lower-power ultrabooks, and "Y" for super-low-power tablets and detachable hybrids. It's confusing, but that's why we compare different PCs with benchmark tests.
