Does anyone know what kind of difference in performance these would posess with 2GB ram in an X61/X61s?

Ive looked through guides but i cant quite find a direct comparison. The difference in weight doesnt seem to be too large so im just wondering how much more powerful the X61 is compared with the X61s?

There are very few comparison benchmarks out there for the LV CPUs. The best apples-to-apples one is this one:

These are the previous Core 2 Duo models, but basically a 2.0 GHz T2500 was only about 6% faster than the 1.66 GHz LV version in spite of a 20% clock speed advantage. Extrapolate to today's L7500 and T7300 (the fastest available on the X61), both now with 4 MB of cache, and I would expect to see a 10-15% performance difference on pure CPU tasks.

Small enough difference, IMHO, to make one pick the X61s with the lower weight and the brighter Ultralight LCD panel.

good good, thats what i was hoping for, plus (i presume) the batter life would be better with a lower voltage!

tabook quotes the battery life (with the 8-cell option shared by the two models) at 7.8h for the X61 and 9.0h for the X61s.

Are you sure it's only a 6 percent performance difference? what are you basing this on?

The benchmark tests on notebookreview.com -- see the link above.

You also have to remember that unless you're constantly compiling code or doing CPU intensive tasks your CPU is idling at a clocked down speed (~1ghz) so both the 1.6Ghz and 2.0Ghz would perform the same.

(They both don't clock down to the same speed - but the point I'm trying to make is that you're not utilizing the full capacity of your CPU most of the time so it really doesn't make much of a difference)
