i5 Vs. i7 VS AMD

Intel Core i5 460M (2 Cores @ 2.53 GHz )
Intel Core i7 740QM Quad-Core (4 Cores @ 1.73GHz )

Why is the supposed faster CPU (i7) actually slower? I need to run Office Apps (Word, Excel, Access), is the i5 better, worse, no different. I am looking for performance when running 2-3 apps at a time (Outlook, Excel and Access or FireFox). Will multi-threading (i7) do anything for me?! I read that there isn't really any difference (2-5% only) between i5 and i7, is this truly the case?

If I run an single program on either will they be running at 2.53 vs. 1.73 or do the cores have a multiplicative factor (5.06 (2x2.53) vs. 6.92 (4x1.73))?

Where does AMD fit into the picture? What is comparable for laptops with the i5 and i7 chipsets?

Thank you.

For your stated uses the i5 is more than enough. It might in fact out perform the i7 in certain usage conditions. But not really in a way likely to matter as both are just so far above office applications needs.

AMD CPU would also function fine. I am not currently up on AMD mobile CPU's so I can't give more info.

the i7 outperforms the i5

i7 says 1.73GHz but it can turbo boost up to 2.93GHz and on top of that it has Hyper-Threading.same with the i5, tho it dont have Hyper-Threading it can still turbo boost up to 2.8GHz from its 2.53GHz.hope this helps.
 
both are good cpus, but the i7 has more cores and threads and also it Boosts to 2.93Ghz, you can check its review before getting the laptop. I think i3 is enough for you, but still i5 would be good for longer future use.

I was informed that the Turbo boost is disabled by the manufacturer and if I enable it and anything happens the warranty is void?! So it may be able to go faster but apparently your not allowed to do so.
