Thinkpads Forum

While poring over the latest tabook.pdf (August 2006 -- V.311), I discovered that some X60s models, like 17044JU, were powered by Intel Centrino Duo technology and marked as such by a tiny (clandestine?) asterisk, while the more expensive ones 1704-66U and 1704-69U -- by regular Intel Core Duo.

This made me suspicious as to the difference between the two in productivity and other parameters.

Any clues?

Why is this information not so widely known and circulated?

isn't centrino simply intel processor + intel wifi?

so if they put in atheros, it is simply intel core duo?

that's my impression.

Thank you, Lucas, for dissipating my doubts. After your comment I looked in the tabook again and saw that you were right -- it is Intel Wifi card that makes the difference.

which one has less heat dissipation?
solo or dual?

The core duo cpu is a nice feature but centrino is nothing more than a buzzword - the ThinkPad wireless card is better IMHO but I don't understand why it is now more expensive and difficult to get hold of in comparison with the Intel card

Here are two quotes from Intel, defining Centrino & Centrino Duo:

"Centrino (also called Centrino Mobile Technology) is a marketing initiative from Intel for a particular combination of CPU, mainboard chipset and wireless network interface in the design of a laptop personal computer. The combination currently consists of a Pentium M processor, the Mobile Intel 915 Express chipset family or the Intel 855 chipset family, and an Intel PRO/Wireless 2100 (IEEE 802.11b), PRO/Wireless 2200 (IEEE 802.11bg) or PRO/Wireless 2915 (IEEE 802.11abg) network connection.

Thank you, Archer6, this is self-explanatory. Howerer, if the real difference is the wifi card, then expensive models 170469U having Atheros card may be more prone to issues with hot right palmrest. Am I wrong? I guess so far there has been no consensus as to whether hot palmrest issue is completely unrelated to wifi card brand.
