The list of Core i7 and Core i5 that will retire is not complete without cheaper CPUs including three Core i3, one Pentium and four desktop Atoms.

Intel will end the life of Core i3 560, Core i3 550 in Q2 2012 and Core i3 530 retires with the end of this week or Q1 2012. These are old 32nm Westmere pre-Sandy Bridge CPUs released in Q2 2010.

Intel retires the Pentium G6960 in Q2 2012, and this is a rather fresh CPU launched a year ago in 32nm clocked at 2.93GHz. It simply has better ones to hold the ground in the essential market. Intel sending off Atom 510 and 525 dual-cores and Atom 410 and 425 single-core that are dating back to Q1 2010, as D2000-series models in 32nm are a much better choice due to superior, HD capable graphics.

Intel will soon be selling three generations of Core processors at the same time, and it has been quite messy with three-digit and four-digit Core processors, hence the first and second generation and with Ivy Bridge you will have Core i7 600, 700, 800 or 900 series, then you will have Core i 2000 series based on Sandy Bridge, and Core i 3000 series with Ivy Bridge, all available at the same time. 

As usual, the bigger the number, the better the chip.
