Urgent: Radeon 6490m DDR5 vs Radeon 6630m DDR3

[MarveL]

Hi friends,

I need to buy a laptop next week and I have shortlisted one HP Pavilion and one Sony Vaio model.

The Pavilion has AMD Radeon 6490m DDR5 GPU while the Vaio has AMD Radeon 6630m DDR3. Both has 1 GB of dedicated GFX memory.

I am really confused which one to choose? I think the 6630m is a better GPU but it's DDR3. does DDR5 make a difference?

Which one should I opt for? Please help me with your suggestion.

looking at the specks go for the 6630m should provide at least double the performance of 6490 even with the DDR3 ram

have a look at this will give u the idea
