I3/i5/c2d

Hey which of the following cards give a better performance ?

(i) i3-350M (2.13 GHz)
(ii) i5-450M (2.26 GHz - 2.53 GHz on turbo)
(iii)core2duo E6700 (2.67 GHz)

I dont know much about the clock rates... I just want to know which of the above mentioned cards give a better , faster and a fluent performance when many windows are open or many applications are running simultaneously.

Also, if ATi mobility radeon HD5650 (1 GB) is factored in i3-330M, are there any possibilities of bottle-necking ?

We're talking Laptops here apparently.

In order of over all performance:
1) i5-540M (I assume this is what you meant since i5-450M is not on Intel's site)
2) i3-350M
3) Core2Duo E6700

Adding an ATI HD5650 would help with overall system performance in any situation, as you offload the graphical processing from the CPU. You'd be able to do some light-weight video gaming if you chose, the Aero option in Vista/Win 7 would perform better as well.

The i3 and i5 chips both are Dual-Core, however they support Hyperthreading (which can help in the future, or with certain types of software). Without looking at benchmarks, the i3-350M will likely perform better than the E6700 even though it has a higher clock speed. Simply because the new i3/i5 chips use a more advanced architecture.

As far as a bottleneck, keep in mind that if you wish to play games on this laptop... you will have an inherent bottleneck just because it's a laptop. Your overall limitation won't just be the CPU, but also the mobility GPU, slower memory bandwidth in the laptop, potentially slow hard disk speed, etc.

Pretty satisfactory reply, thanx for that...
One more query..

How would u rate the following performance wise ? as in, which one is better for the above said factors ?

1) ATi mob radeon 5650 + i3-350M
2) ATi mob radeon 5470 + i5-450M

Compare both i3 and i5 processors:

The i5 has TurboBoost, the i3 does not. So there's an advantage there.

As far as the ATI 5650 and 5470 are concerned. With a laptop your biggest bottleneck for any kind of gaming (I'm only assuming you want to game) is the GPU. Generally laptops entirely lack a dedicated GPU.

So personally, I'd rather have the i3 with the faster GPU than the i5 with the slower GPU.

Thanx a lot

For example:

3dMark05 Scores:
ATI 5650 = 13103
ATI 5470 = 6380

I'm not sure if the comparison holds for mobile cpu's- I've built some desktop machines with the i5-750 and compared them with my machine with the c2d. The i5 would run superpi about as fast as a c2d running with 10% higher clock speed.
