Intel has added three new chips to its core i5 and i7 chip ranges that are designed to go in ultraslim portable devices.
The additions appeared on the Intel processor price list on Sunday and show two new Core i7 chips and one new Core i5.
The two new second-generation, Sandy Bridge, i7 processors are the dual-core i7-2677M with a clock speed of 1.80GHz and the dual-core i7-2637M which has a clock speed of 1.70GHz. Both processors have a 4MB cache and are listed as being ultra low-voltage (ULV).
The new Core i5 processor is the 2557M, which is also a dual-core chip and has a 3MB cache and 1.7GHz clock speed. All of the chips can be 'overclocked' to work at higher clock speeds.
On 31 May, Intel outlined its vision for the future of ultra mobile devices which it calls 'ultrabooks'. The ultrabook category combines best-in-class performance with improved responsiveness and security, Intel said.
