I've searched the net and cant find the specific answers I'm looking for regarding this issue.
Which graphics option is better for the Mac mini when connected to an Apple Thunderbolt display running at 2560 x 1440 resolution:
1) AMD Radeon HD 6630M with its 256mb GDDR5 memory
2) Intel HD 3000 with 512mb of memory ( i.e. I will upgrade the Mac mini to 8gb or RAM to get 512mb of video memory).
Now will the HD 3000 with its 512mb of system memory be better simply because it has more, or will the AMD 6630M be better because even though it has less memory it has faster GDDR5 memory as opposed to the DDR3 memory the Intel GPU will use?
I tested out the AMD 6630M in an Apple store and when I had multiple Safari windows open it struggled a bit when I used expose. It stuttered and lagged and the animation was not smooth. Would the Intel 3000 with 512mb ease this problem?
