Intel Releases ULV 17-watt Sandy Bridge CPUs
Low power for the speed.
Intel has released a few new ultra-low voltage processors that will likely find their way into this year's gang of Ultrabooks for the 2011 holiday season.
The new processors listed by Intel are as follows:
- Core i7-2677M: 2 cores, 1.8 GHz (turbos to 2.9GHz), 4MB cache, 17 watts, $317
- Core i7-2637M: 2 cores, 1.7GHz (turbos to 2.8GHz), 4MB cache, 17 watts, $289
- Core i5-2557M: 2 cores, 1.7GHz (turbos to 2.7GHz), 3MB cache, 17 watts, $250
The Core i5-2557M has already found a home in the Asus UX21 that was modeled as an Ultrabook at Computex earlier this month.
Apple is also expected to refresh its line of MacBook Air laptops with this new family of chips. Apple's current MacBook Air still use Core 2 Duo CPUs paired with Nvidia chipsets, as license agreements prevent the pairing of Nvidia technology with Intel's current generation of processors. The integrated graphics of Intel's Sandy Bridge chips, however, will likely be enough to satisfy Apple's performance targets for the MacBook Air.

I still don't get Intel's naming conventions for the mobile space - I can understand wanting to go "above" i3 if you're turning on turbo, but calling a dual core chip (even with HT) an i7 is just taking the biscuit.

It's because these chips are based on the same architecture and design as other i7 CPUs. They have 4MB of L3 cache compared to the i5 which have 3MB and run at a higher clock rate. They are the i7 equivalent of ultra-low power CPUs. Only compare model description within the same category.
