Does Socket S1 Sempron draw less power?

[paulsiu]

In the various review of Turion X2, the articles indicated that the two cores actually draw roughly the same amount of power as the single core Turion. They attribute this to the improvement in the cpu. This got me thinking if the socket S1 sempron draw less power than a dual core Turion x2, if they are essentially a single core version of the Turion x2.

Is there a sempron for socket S1?! I don't believe so -- just socket 754 and AM2 for sempron.

Well what do you know? Thx for the info. Based on the name "Keene" from wiki I also found this at

AMD Mobile Sempron (Keene) mobile processor was quietly released in June on a 90nm SOI process. Keene is a single core CPU with 256KB or 512KB L2 cache designed for Thin and light laptops and is the single core version of Trinidad (62W) and Taylor (35W). Keene is expected to be released on Socket S1 and feature a DDR2-667 memory interface and have a 25W TDP. The initial members of the Keene family are:

Mobile Sempron 3500+ (1.8GHz/512KB L2)
Mobile Sempron 3400+ (1.8GHz/256KB L2)
Mobile Sempron 3200+ (1.6GHz/512KB L2)

So, at 25W, these semprons draw less power than either or the dual-core variants at 35W (for "thin-n-light" laptops) and 62W (for "dekstop replacement" laptops)
