Four low-power mobile Sandy CPUs debut

Intel seems fond of adding processors to its price list on quiet Sundays every now and then. That's just what happened with the latest batch of ultra-low-voltage Sandy Bridge mobile processors, which showed up out of the blue in the chipmaker's June 19 price list update. Here they are:

Processor Cores/
TDP Price
Core i7-2677M 2/4 1.8 GHz 2.9 GHz 4 MB 17W $317
Core i7-2637M 2/4 1.7 GHz 2.8 GHz 4 MB 17W $289
Core i5-2557M 2/4 1.7 GHz 2.7 GHz 3 MB 17W $250
Celeron 847 2/2 1.1 GHz N/A 2 MB 17W $134

All four offerings have 17W thermal envelopes and FCBGA1023 ball-grid-array packages, so they're sure to show up in ultraportables from various manufacturers. The Celeron 847's low price should make it ripe for cheap consumer ultraportables—the kind that rub elbows with Atom netbooks yet feature better displays, faster hardware, and Windows 7 Home Premium. 1.1GHz without Turbo Boost or Hyper-Threading isn't exactly fast, though, even by Sandy Bridge standards.

The folks at AppleInsider also expect some of these new chips to show up in Apple's revamped MacBook Air laptops this summer. Whatever processors Apple ends up using, the upgrade will have been long overdue—current variants of the MacBook Air are still toting old Core 2 CPUs.
