Pentium M vs Pentium M 7xx

Archived from groups: comp.sys.laptops (More info?)

Intel currently has 2 Intel pentium M cores: Banias with 1 meg L2 cache,
larger die, uses more energy, gives off more heat and also is the older of
the two. The other is the Dothan core which has 2megs L2 cache, smaller die,
faster, cooler chip and newer. The 705 is based on the banias core and the
715 is based on the Dothan. They both run at 1.5Ghz. If only Pentium M is
indicated, its almost surely a banias. You would need to check the speed
though. Just for comparison speed wise, 1.5Ghz Dothan ~ 1.6Ghz Banias, but
don't forget the dothan has other features which set it apart from the
banias.

| batt-life with office docs stick to Dothan core(older one). If you need
the
| horsepower then a Banias is the way to go!!

You seem to be confusing the Dothan and Banias cores.
