Hello and welcome to the forums
Between those CPUs,i3 380M> i5470UM>P6200

Thanks for reply but how come an i5 is slower than an i3. Also What's the difference between core 2 duo and i3 as both have 2 cores.

i5 is slower because it's a ultra low voltage CPU;therefore,it runs slower than normal i5's and is slower than i3 380M.
Core 2 Duo and i3 have different architectures,and the later is usually faster in most cases.

thank you. so all processor ending with UM like 5470UM are low voltage processors? is there any site where i can compare different processor (amd and intel) for speed and performance. as i dont feel good to post these basic questions again and again.

can anyone tell me which one is the better option for laptop

DELL - Intel Core i5-460M Processor (3M cache, 2.53 GHz) (REFURBISHED)
Toshiba - AMD Phenom II Triple-Core Mobile Processor N850 2.2 GHz, 1.5MB L2 Cache
Toshiba - AMD Turion™ II P560 Dual-Core Processor
Dell - Intel® Core™ i3-370M (2.4GHz, 4Threads, 3M cache)

any help would be appreciated

In terms of performance the Dell i5-460M has the most processing power, while it is a dual core processor its 2 cores get more work done per clock cycle than the Phenom II triple core. What do you plan on using the laptop for? If you are doing any gaming than you would need a graphics card.

i will using it mostly for programming and graphic designing stuff. dell i5-460m is a refurbished laptop whereas all other are new. how much difference of performance will be? will it be significant?

No its not significant, the main difference between i3 370M and i5 460M is that the later runs only 100MHz faster and has turbo tech.
