Leopard runs very nicely on 1.5GB Ram. I know a person running the beta who has open the following apps on 1.5GB (Just asked him on IM):
So 1.5GB seems pretty good
- iMovie 08
- iPhoto '08
- Dreamweaver CS3
- AND he also has a 720p Movie playing on VLC...
The RAM usage doesn't escalate like that. More effects does not always equal more RAM. Considering the GUI sits on top of OpenGL, CoreAnimation leverages OpenGL technology for the animation, making most animations just a series of commands sent to your GPU, like everything in the UI already does.When I'm talking about Tiger, I think 512 MB is enough just for the operating system and because Leopard has so many more visual effects, I'd say it's going to take 768 MB to 1 GB.
At the same time, I'm 99 % certain that the necessary RAM for good performance on Intel-based machines will be less than it has been for Tiger--that Leopard will run better with the same machine, a lot better.
It's difficult to believe that it runs well at all with 512 MB but nevertheless, it will likely run more poorly once they finish the bug fixes. Every other beta has looked good up until the end and then, performance slows a lot as correct operation is more than somewhat desirable.Leopard (WWDC 07) runs pretty darn good on a 12" Powerbook (1.5Ghz and 512MB Ram). And from what I've read and heard, the latest build is even faster with the same configs. They are doing some amazing optimization, so I wouldn't doubt that 512MB would be enough for the light users with 1GB being a sweet spot for normal users.
I've read it's a bit slow, like running Tiger on a G3,(Which I can vouch for) but it is completely do-able.okay, so two of my PPC's that will be ugraded to Leopard (dual 867, dual 1.25) have the RAM maxed at 2 GB. However, the VRAM is only at 32, and 64, respectively. I know I am going to ugrade the cards in the towers, but will 128 be sufficient, or should I go to 256? I'd rather not spend the extra money for these old systems. Just want them both to last through Leopard. I don't do to much graphics work, mainly editing /creating scientific figures for publication. Everything works well enough at the moment with Tiger.
Any suggestions from beta users on G4 towers would be appreciated.
