Ivy Bridge processors from Intel are coming next month, reports “CPU World” (http://macte.ch/McB5h), quoting two unnamed sources. Whenever they arrive, they’ll certainly be making an appear — and soon, we’d guess — in desktop and laptop Macs.

The article says Ivy Bridge processors will be announced in the fourth week of April, between April 22 and April 28. The announcement will include only quad-core models: mobile Core i7 and Core i7 Extreme families, desktop Core i7, Core i5-3570K, i5-3570T, i5-3550, i5-3550S, i5-3450 and i5-3450S.

The announced chips will be available for sale on April 29, and the reviews and benchmarks should be published on the same day, says “CPU World.” Other versions of the Ivy Bridge chip will be unveiled as the year rolls on.
