Intel has started shipping its 65nm dual-core mobile Pentium processor, Yonah, along with Centrino bundles based on the new processor.

As expected, the chips use Intel's new model-numbering scheme. The T2600, T2500, T2400 and T2300 are dual-core parts - hence the '2' - and are joined by one single-core chip, the T1300. The five processors are clocked at 2.16GHz, 2GHz, 1.83GHz, 1.66GHz and 1.66GHz respectively, and operate on a 667MHz frontside bus, connecting across a FCBGA6 or FCPGA6 pin-out. All processors sport 2MB of L2 cache.

The T1300 is priced at $209 when sold in trays of 1,000 CPUs. The dual-core chips, moving up the line, cost $241, $294, $423 and $637 respectively. For now, Intel has not cut the prices of the older Pentium M 7xx series.

Intel has also launched a pair of low-voltage dual-core Yonahs, the L2400 and L2300, clocked at 1.66GHz and 1.5GHz respectively. Both use a 667MHz FSB, and are priced at $316 and $284 respectively. They debut alongside the 1.3GHz ultra-low voltage Pentium M 733, which costs $273 in batches of 1,000 chips.

The 773, L2300, L2400, T1300, T2300, T2400, T2500 and T2600 are also available in a range of Centrino bundles combining the CPU with a number of chipset options - including the new 945GM and 945PM parts - and Intel's 802.11a/b/g Wi-Fi adaptor, the ProWireless 3945ABG.

Prices for the Yonah-based Centrino bundles start at $274 for the single-core T1300, the discrete 945PM chipset and the 3945ABG, rising to $706 for a combination of the T2600, integrated 945GM chipset and the 3945ABG. 773-based bundles range in price from $332 to $338. ®
