Which is faster

Trying find a decent buy for a friends laptop purchase, narrowed it down to
a few but still unsure on mobile cpu's so have made a shortlist given other
things he needs, hard drive etc and am left with the following cpu choices.

Intel Core 2 Duo (T5470 - 1.6GHz, 800MHz FSB, 2MB)
Intel Core 2 Duo Santa-Rosa (T7300 - 2.0GHz, 800MHz FSB, 4MB)
Intel Core 2 Duo (T5800, 2.0Ghz 800 FSB 2MB L2 cache )
Intel Core 2 Duo Santa-Rosa (T5750 - 2.0 GHz, 667MHz FSB, 2MB)
Intel Core 2 Duo processor T6400, 2.00 GHz, 800 MHz, cache : 2 MB
Intel Core 2 Duo processor T5800, 2.1GHz, 800 MHz FSB, 2MB Cache
Intel Core 2 Duo processor T6400 2.13GHz, 2MB L2 Cache, 800Mhz FSB
Intel Pentium Dual-Core Processor T3400, 2.13GHz
Intel Pentium Dual-Core, 667Mhz, 1MB, T3400, 2.16Ghz
Intel Core 2 Duo Processor T5750 / 2 GHz
Intel Core 2 Duo Processor T5870 (2.0 GHz, 2 MB L2 Cache, 800 MHz FSB)


Can I be so bold as to ask somebody to post them in order of speed and is
there any real difference in the real world using (4 GB of ram 5400rpm SATA
harddrive), I think I know there order but don't want to do anything until I
have ran it past some people who I know will know more then me.

TIA

Core 2 Duo is faster than Dual-Core so eliminate those two.

Among the others, the fastest clock speed is the fastest CPU since all are
Core 2 Duo with the same FSB and cache.

The T7300 2.00 GHz Core 2 Duo will be the fastest since it has the most cache
and is only slightly behind the 2.13 GHz T6400 in clock speed. I don't think
you'll see any difference at all except in benchmarks with this group, though.
Other factors such as speed and amount of RAM, hard drive speed and graphics
chip will probably be the ultimate deciding factor.
