I’m not sure what your problem is. If you are asking which is a more powerful cpu, that would be the P8400. The P8400 should have a longer battery life as well.

Thanks alot for paying heed to my querry you are rite i think i didnt phrase my question the rite way i should have asked that which one id faster and can you guide me about the series of these processors in the ascending order. Ill be extremely grateful to you for your help and will be waiting anxiously for your reply.

Speed wise, they are clocked about the same. The T6600 has 2mb L2 cache and the P8400 has 3mb. Probably not a big enough difference to make a noticeable change in speed. The T6600 is a 35w CPU and the P8400 is a 25w.

Are you trying to figure out if upgrading from the T6600 to the P8400 is worth it? I would say no, save the money. If you're looking for a performance boost, what OS do you run and how much ram? If its Vista, you'll want 2 gbs. XP can get away with just 1gb if you don't have tons of services loaded up.

Thanks alot once again now im just left with only one querry and that is what do you think what the difference in core i3 and core 2 duo if we talk specifically of SONY VAIO. Like i bought a vaio with T6600 processor and what would be the affect if i buy core i3 and how much of performance difference would it be. Because i had a debate with one of my friends but i would like to listen to a expert opinion. plz help me with this too okay THANKS alot for your help.

Since you're asking for an expert, I'll have to fake it.

Performance increase is dependent on what you're running that you more you need. The i3 is a dual core CPU, but it does Hyper-Threading. That means the CPU will tell the programs that there's 4 cores so that it gets 4 streams of data to process (or threads.) Since the data to be processed usually isn't constant and there's time the CPU isn't doing anything while its waiting for information to process. So if the applications are providing 4 threads, each core can bounce back and forth between the pairs of threads during that down time and spend less time idle. If you're doing HEAVY multitasking, being able to run 4 threads is better than 2. But if its just general surfing and productivity applications, probably wouldn't notice a big increase in speed over either of the other 2 CPUs. The core i3 mobiles are also 35w CPUs and have the graphics on the CPU. So power consumption would be more than the P8400 but less than the T6600.

If you already have the T6600 or P8400, you can't upgrade to the i3 mobile as it uses a different socket and motherboard chipset.

Thnx, alot but u know i wanted to ask that for normal applications there is no difference in operartion and performance but core 2 duo has four processors too rite if im wrong just let me know.

Core 2 DUO (TWO) are dual core CPUs.

Core 2 QUAD (FOUR) are the quads.

All 3 CPUs you're listed are dual cores, but only the i3 supports Hyper-Threading.
