Intel's 'Merom' dual-core mobile chip will ship in two forms, one with 2MB of L2 cache, the other with 4MB. Unlike 'Conroe', however, the smaller-cache parts will get their own model number sequence, it has emerged.

Merom will ship in August under the Core 2 Duo brand. According to a DailyTech report, the 2MB version will ship as the 1.83GHz T5600. Three 4MB parts are set to ship next quarter: the 2GHz T7200, the 2.16GHz T7400 and the 2.33GHz T7600. All four processors support a 667MHz frontside bus.

Prices for the five mobile CPUs are quoted at $240, $294, $423 and $637, running up from the T5600 to the T7600. Come Q4, and Intel will ship the 1.66GHz 5500 at £209.

That's pretty much it until Q2 2007 when 'Santa Rosa', Intel's next incarnation of Centrino, ships and the T7700 makes its debut. So will the T7300 and the T7000, along with a variant of the T5500, the T5500P. The Santa Rosa parts will support an 800MHz frontside bus.

Q1 2007 is set to see the arrival of low-voltage Core 2 Duo parts: the L7200 and the L7400, both joined the following quarter by the ultra-low voltage U7500, and the Santa Rosa-ready L7500 and L7300. ®
