If by "serious facts" you mean hard statistical evidence, then I do not have that. I do however have somewhat of an idea from what others who have both 32-bit and 64-bit versions of the same distribution installed have reported across the various newsgroups I'm subscribed to. > Comparing different OSes and software and claiming that the difference > is due to 32 vs 64-bit does not sound serious to me. I wouldn't stretch that "different OSes and software" concept too much, though. PCLinuxOS is a Mandriva derivative, and so is Mageia. The only real difference at the operating system level is the package manager. Both systems have 2.6 kernels - 2.6.26 for PCLinuxOS, 2.6.38 for Mageia. That said, I did say that the PCLinuxOS distribution uses KDE 3.5 and this Mageia here uses KDE 4.6. Granted, there is a generational difference at play there, but it's still KDE, and the KDE developers did not exactly throw away _all_ of the code base of KDE 3 when they developed KDE 4. Furthermore, the applications used at the time of the check were the same for both installations. Essentially only one logged-in user, running KMail (e-mail client), KNode (news reader) and KVIrc (IRC client). Cache may vary in size due to frequent opening and closing of Firefox sessions and other applications. It's not like I'm comparing GNU/Linux with Solaris or FreeBSD, or even with BeOS, IBM OS/2 or Microsoft Windows. It's the same operating system, just a little bit more modern in the event of the 64-bit system. The hardware is the same as well, as both distributions are installed side by side on this machine here. When cache is taken out of the equation, then I would say that the difference in RAM consumption between the 32-bit PCLinuxOS and the 64- bit Mageia sits somewhere in the 400 to 500 MB range. This difference could be smaller if both were indeed only different "bitness" versions of the exact same distribution, but I estimate that the difference would still be in the magnitude of 200 to 300 MB, with the 64-bit system consuming the most of the two. It is a fact: 64-bit systems use 64-bit integers and 64-bit pointers. Inevitably this leads to greater memory consumption on the part of the 64-bit system. It won't be anywhere near the Microsoft-touted claim that a 64-bit system consumes or needs twice as much RAM as a 32-bit system, but there /is/ a difference. That is exactly why the x32 platform was conceived. -- = Aragorn = (registered GNU/Linux user #223157)
