Are there any trade offs with having 2x512MB in a PBook 15" 1.5GHz? as opposed to one 512MB...
Power consumption, battery ? Heat ?
How much better would 1GB be than 768MB ?
And, how much worse would 512MB be than 768MB ?
I run my 900mhz-upgraded B&W G3 with 768MB (much of that swiped from the old PC that's sitting gathering dust in the hallway, because it was left with so little RAM that Windows XP will probably barely even load...oh, wait, I think I felt sorry for it and stuck a bit more in when it was cheap somewhere...), and it seemed better than when it had 512, but I think any easing of bottlenecks in that kind of machine is going to help. (just wish I had a PCI-X slot, the 66mhz one is an insult to my Radeon 9200)
My 12" iBook runs cooler and longer at 1.2ghz with 768MB than my old 12" PB at 867mhz and 256MB (this was the machine the "iMac" RAM was supposed to fit), and of course, significantly faster. Not really having an equivalent machine to compare, I'm still going to make a wild guess and say that the additional RAM will probably be more than worth any potential heat/battery tradeoffs.
