Anyone know detailed explanations for situations where 64-bit is more/less beneficial and why? large numbers? but the 64bit amd extension is really, really helpfull, when you need registers. The additional registers are a huge advantage and can give you a nice boost. Can, not have too - it depends on the task and how the software was compiled. -- gentoo-user@gentoo.org mailing list

Re: [gentoo-user] 64bit vs 32bit
Depends on what you want it for. I personally have two AMD 64 systems - one at work and one at home and have one running 64 bit (work) and one 32 bit (home). My experience is that yes you can get most major apps running on a 64 bit system through the use of 32 bit bins but there are still a lot of the more exotic apps that are not available in the 64 bit world. For the hardly noticable increase in speed from the 64 bit apps and the aggravation in getting things to work - I would go for 32 bit - everything is available and just works. I found that it was just too much hassle trying to get everything working in 64 bits so converted my home system from 64 to 32 and if I had the time would do the same at work.

Neither of these ebuilds have an amd64 keyword. This does not mean they don't run on amd64, only that they haven't been tested. If the packaged had been tested on amd64 and failed, it would have a -amd64 keyword. -- Neil Bothwick Micro-: (prefix) anything both very small and very expensive. signature.asc Description: PGP signature

[gentoo-user] 64bit vs 32bit
Hi, I am planning to buy a new machine and lately I was thinking about a AMD64 X2 4800+ 2GB RAM. Is it worth to install 64bit linux or should I go for 32. As I have read there are issues with video stuff, flash player. This machine is for work and entertainment. I don't like the idea of a 32bit chroot if it's too much of a hassle to set it up.

I don't like the idea of a 32bit chroot if it's too much of a hassle to set it up. The default amd64 profile includes multilib, so there are no worries about 32 bit compatibility. I run no multilibs on my machine and the only difference I've noticed is that those annoying flash ads don't work. (-: Justin -- gentoo-user@gentoo.org mailing list

I don't like the idea of a 32bit chroot if it's too much of a hassle to set it up. Just from the technical side of things, AMD64 architecture is fully compatible with 32-bit applications. You can install a 32-bit app in a 64-bit OS (but not the other way around : ( I'd suggest the amd64 OS, though if you can't decide, I'd just throw in the towel and dual-boot. Also, using a 64-bit app is only going to get you about a ten percent performance increase, according to benchmarking studies of people with more money than I have. It's ultimately up to you, but if I were you, I'd take the adventurous route and go 64-bit - just for the heck of it. However, I don't know enough about your wants and needs to be able to reccommend something like that. Do what you want: that's the entire point.
