Intel won't be the first to deliver processors for ultrathin laptops. Advanced Micro Devices earlier this year introduced a single-core Neo chip, which went into Hewlett-Packard's Pavilion DV2 laptop. AMD is set to bump up Neo's performance with a dual-core version, which will find its way into laptops soon.

Along with the low-voltage processors, Intel also introduced three standard-voltage processors, including the first Core 2 Duo to cross the 3.0GHz threshold. The dual-core T9900 runs at 3.06GHz, includes 6MB of cache, and is priced at $530. The P9700 runs at 2.8GHz, includes 6MB of cache and is priced at $348. The P8800 runs at 2.66Ghz, includes 3MB of cache and is priced at $241.
