I saw a screenshot of SL activity monitor with lots of 64bit stuff like Calculator (why?) taking up double the RAM compared to the Apps I see running on Activity monitor now.
.....
So if it uses double the ram, will my old 2.2ghz MBP which only supports 4ghz ram be able to be upgraded to 8ghz once 10.6 is installed? Like will 10.6 recognize 8 ghz where 10.5 could only see 4?
interesting so is the ram increase namely due to going to 64bit?64-bit means that every long, pointer...etc takes twice the memory. It effectively doubles RAM usage.
From Wikipedia:
"The main disadvantage of 64-bit architectures is that relative to 32-bit architectures the same data occupies more space in memory (due to swollen pointers and possibly other types and alignment padding). This increases the memory requirements of a given process and can have implications for efficient processor cache utilization."
It sounds like something bogus made up by people who don't understand technology properly, but it's true. There are ways to reduce the effect, but I don't know if Apple are doing anything like this.
its gb, not ghz and no, if your computer only supports 4gigs, that all it will ever support
the ram increase is what leopard will need to use software wise

if i have a core duo machine and wont be utilizing 64 bit, would my ram requirements be below what apple reccomend at 1 gb, and be essentially 512mb?

Actually it's GB, not gb.
GB = gigabyte
Gb = gigabit
gigahertz is technically GHz, but I won't call you out on it.

Since you want to be understood correctly? Or maybe since you want to give the impression of basic literacy?
So does this mean that users who don't upgrade their RAM may actually see a decrease in performance? Or will Snow Leopard make up for the increased RAM usage some other way? I planned on upgrading to 8GB of RAM at some point but not for a quite a while.
I second this question. My Rev.1 C2D MBP can only handle 3gig max. I can't increase the RAM beyond that. Will I possibly see a decrease in performance upon upgrading to SL?
