An Intel spokesman declined to comment on the laptop listing. HP did not immediately respond to requests for comment.

Earlier, a Canadian retailer, A-Power, listed the Core i3-530 chip for desktops running at 2.9GHz. That listing has been pulled off the Web site. The dual-core chip included 512KB of L2 cache and 4MB of L3 cache.

The new chips are part of Intel's Westmere architecture and will be manufactured using the latest 32-nanometer process. Intel's existing chips are made using a 45-nm process.

Westmere is based on the same micro-architecture underpinnings as existing Nehalem chips, which are made using the 45-nm process. Nehalem chips include Core i5, Core i7 desktop and Xeon 5500 server chips.
