You can get them either way. The iMac uses the faster GPU because it has more room to dissipate heat, however the 21" is the lower end, so it doesn't get as much VRAM. The MBP can't dissipate as much heat, but the 1GB cards come in the higher end models.
Apple says that you have the 1GB VRAM of the 6750M if you buy MBP.
But iMac 21" have 6770M with 512MB?
Why faster processor with less RAM and slower with more RAM?
They did this to force people to buy the higher end model and for them to make more money.
i mean iMac 21 high end
so MBP 2.2Ghz can process more game than 21" high end imac?????
typical apple x.x
I know it is the high end 21, but the 21 is lower end to the 27, just like the 13 MBP is lower end to the 15. VRAM isn't relevant until you get into some pretty high settings in new games or are running multiple displays. Either way, 512MB isn't bad.
And every other computer manufacturer out there.
1gb is the minimum id use,
most people who game on macs suffer the lowest settings and consider this to be "gaming"
Personally if im using anything below EXTREME settings then i may as well use the PS3.
Even though the iMacs have better cards, they're also rendering graphics at a much higher resolution. Something to consider.
VRAM isn't everything.but the 6750M of the mbp have 2x more vRAM?
VRAM isn't everything.![]()
