What is the difference between these video cards for a laptop...?

256MB ATI Mobility Radeon HD4330

Intel Graphics Media Accelerator X4500HD

i am ordering a laptop off of dell.com, what is the difference? i'm guessing the first one is better because its more expensive. i plan on using this laptop for music pictures it has a web cam and my friends and i edit movies, nothing big though just like youtube vids(I'm 16). so how important is this component etc. thank you!|||Intel Graphics Media Accelerator X4500HD is onboard graphics and tends to be weak because it "borrows" RAM from your motherboard.



The Radeon is a dedicated graphics card and faster. It has its own video RAM.

*|||For editing movies, you would probably want the ATI card. It will outperform the Intel card by a longshot. It is worth the extra money.|||The top graphics card is "dedicated memory", which means that it has 256MB of memory that it uses only for the graphics card. The bottom is integrated, which means it processes graphics with shared memory. The top is better since it will always have memory to work from. If you aren't a gamer, you should go with the cheaper Intel card. :)
