Do higher dedicated video memory in graphic chips of a laptop heat more?

Hello,
I am in a dilemma whether higher dedicated video memory of the graphic chips like Nvidia or ATI Radeon cause the laptop to heat more? I'm planning on buying a Sony Vaio laptop and I'm down to two choices which differ in their graphic card memory, one has a 1GB ATI Radeon and the other has a 2GB ATI Radeon. I'm worried whether the 2GB graphic card will heat up more and cause damage to my motherboard. (I lost my previous HP laptop in the same way)
