Just make sure 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.

They're still all Core i3, i5, and i7 processors, ranging from i3 (slowest) to i7 (fastest), with a variety of speeds and types for each. You'll never see 'Haswell' anywhere on an actual product box, so strike that from your memory. A number of systems will pop up over the next few months, but by the fall most PCs should have them - not all, though. Intel leads with the high end first, then releases the middle-range processors (in other words, the ones you'd want to buy) later on. You can get PCs with the higher-end quad-core processors first, but these are expensive, high-performance machines. When can I get PCs with these new processors? The Razer Blade 14 has a fourth-gen quad-core i7. 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. The last generation, code-named 'Ivy Bridge,' was released mid-2012. Haswell is Intel's code name for the fourth generation of Core i-series processors, those ubiquitous chips found in nearly every laptop, desktop, and (Windows) tablet out there. For a detailed rundown on the quad-core processors, check out our hands-on look.

This FAQ will mainly focus on the dual-core processors and what they'll do for mobile systems. Intel has officially revealed its next-generation lineup of desktop and mobile processors in the Core i3, i5, and i7 family, also known as 'fourth-generation' or code-named 'Haswell.' The two-part announcement started over the weekend with Intel's quad-core enthusiast-level processors, and now the veil has been lifted on dual-core desktop and mobile processors, too.
