Smile which is best, 32 or 64 bit version for a new Mint 18 install ?


For my 2009 multiple booting desktop computer, Windows 7 64 bit mostly and several Linux, which is best, 32 or 64 bit version for a new Mint 18 install ? And what advantages are gained if any, when I install the 64 bit version.?

For that hardware you want to go 64-bit.

First, 64-bit addressing is more efficient, but also only the 64-bit kernel can manage more than about 3.5G of ram directly and efficiently due to the 32-bit addressing issues. On certain processors with limited memory there may be a small advantage to running 32-bit, but unless you have such a minimal system it is better to go 64-bit.

Note that some major distributions have either dropped 32-bit support, or have a plan and schedule for doing so. It make twice the work for them to compile packages for two bit-width versions of every single package, as well as eating significant extra storage space. I like to re-purpose older hardware, and have some servers and laptops that do not support 64-bit operation so I deeply appreciate those who still maintain 32-bit versions, but everywhere it will work I have moved to 64-bit and regret nothing.

I'll agree that 64 bit seems to be the choice for you. Good news is you now have time to test both and you should. Generally 64 bit could be slightly faster, could either allow or prevent some programs from running or easily running. I think would be better choice for using vm's. Uses more memory sometimes.

The reason you'd consider 32 bit is some programs that have limited support. Lack of ram maybe. Older hardware. Bios or firmware issues maybe.

If your hardware is natively 64-bit (as, undoubtedly, it is ...), then you should always use a 64-bit OS.

This OS will know how to run "32-bit" applications by putting the processor into an appropriate backwards-compatibility mode while running that application, but you do not want that CPU "running around on training wheels with one hand tied behind its back" all the time.

According to Linus only 1 GB of RAM is accessed properly in 32-bit.

Okay then and thanks for the replies. Also how about a Linux 64 bit installed onto a solid state drive,(it is a Intel 120 GB), will that work good?

SSD is much faster, otherwise works the same way as the hard disk drives. So that will work very well.

32 and 64 has almost nothing to do with SSD unless you have a very old 32 bit OS. Almost all modern distro's have support to properly use a SSD. Many web pages on that subject.

The Intel is a good model. Every once in a while you find an older system made for mechanical drives stumble on fast SSD drives.

I agree with the above -- 64 bit is the way to go. Aside from things like the memory access model 64 bit is compiled to make best use of the instructions set of modern processors and some applications will actually work more efficiently in 64 bit land. The example I always give is a friend who makes music on his PC who went from having denormal and other issues affecting performance with 32 bit to no issues whatsoever in 64 bit and was annoyed I'd not pushed him to 64 bit sooner.

I never understood why people use 32-bit Linux on their 64-bit hardware. Linux went 64-bit when, 2003? Now 13 years later 64-bit versions get much more attention from developers. I see on Gentoo forums users have problems with 32-bit. One possible reason new users use i686 is probably they think amd64 won't run on their Intel processor?

I run into several use cases where 32-bit comes in handy. I would like to mention two:
1. I have a very capable server with about 18 rotational SCSI drives totaling nearly 3.2T, about 8G ram, the CPU is 64-bit capable but the MB and circuits do not support 64-bit. Until recently it was running CentOS5, today it is running Debian. (CentOS 7 is only readily available in 64-bit.)

2. While 64-bit makes an excellent host, containers in many kind of virtualization where the cores and ram will be limited can run 32-bit with better efficiency. Here all of the big advantages of 64-bit are generally wasted anyway.

Is this your own experience, or do you have some links related to this?

From the other hand I have a game (Descent3) played on linux and I wanted to apply the latest available patches (to the linux engine). I had to create a 32bit os (in a docker container) to be able to make those patches working. But I do not think this is a reason to install 32bit system.

Experience.

I have found that the 32 bit distro runs faster and more reliable most of the time in situations of virtual containers with limited resources. Not always, and in some very recent cases the 64 bit images are as small as the 32 bit. When working up a project I find it best to test both if both may be an option.

That said, the last time I found 32-bit better on 64-bit HARDWARE was back in 2004. It probably still happens, but I have not run into it in over 12 years.
