GT 645M is slightly more powerful,but the difference between the two is minimal.
Get the cheaper laptop.

 

[Cryteknologi]

well ...... both almost had same price

The GT 740M is the better graphics card of the two, only just.

Depends on the entire system, Not just those two components.

i heard the gt 740m was 64 bit ? is that right ?

 

[unknownofprob]

yes, correct.

 

[Cryteknologi]

is that mean the gt 645m with 128 bit was more better than the 740m one ?

 

[unknownofprob]

well there are two versions (64 bit and 128 bit...should have stated that before), and the wider bus does not mean it will be better.

Since the graphics performance of the laptops is similar , get the brand you trust more ! If you like GT 740M , could ask them if it is 64 bit or 128 bit GPU .

GT 740M and the GT 645M are very similar in terms of performance,but the 645M is slightly stronger
You can know that by telling what the last two numbers are.
The higher they are,the stronger the GPU is.
For example,GT 650M is stronger than GT 640M.GT 860M is stronger than GT 750M and so on.
