The computer processor is and will always be an important consideration when purchasing a computer. Processor is considered the brain of the computer. The CPU fetches instructions of program from main memory and executes them one by one. The speed of the CPU is measured in Mega Hertz or Giga Hertz and speed from 500 MHz to 3.4 GHz, it depends upon a user needs, that is why purchasing a processor is an important consideration when building or buying a computer. There are several considerations and additional information about what to ask and look for when purchasing a processor directly or already installed into a computer.Intel has introduced a new and flashier set of logos for their consumer-level processors and processor-cum-chipset combos, along with a star-rating system that may generate more trouble than guidance.
The new logos feature the familiar Intel logo above the marketing names of Core i7, Core 2, Centrino, Centrino 2, Atom, Celeron, and Pentium, with small print below listing qualifiers such as Extreme, Duo, Quad, and vPro.
The upper-right corner of the logos show a slice of a chip die in chip-like colors for the Core and Centrino families, but - oddly - in blue for the other
One blue-chip logo has no family name, just the time-honored "Intel inside" slogan. All the other logos include the term "inside" in the lower-right corner.
These rankings divide the Intel desktop and notebook offerings into five groups in ascending order of potency, with the one-star Celerons clinging to the bottom rung and the top-flight Core i7s and Core 2s standing proud on the five-star top rung.
While the star-rating system is a noble goal, it has one fatal flaw. Processors will inevitably slip down the ladder. And when they do, their rankings may change in Intel's marketing department, but not necessarily on shop shelves or salesfolks' minds.
When this first round of rankings expires at the end of September 2009, the confusion will begin. In early October, expect even those highly trained, whip-smart Best Buy sales associates to be flummoxed when trying to explaining why yesterday's laptop with a three-star Core 2 Duo mobile processor is as capable as a laptop that arrived after the Core 2 Duo mobile was re-starred at two.
