32bit or 64bit Ubuntu / Linux etc..

Interesting reads..

To no surprise compared to our 32-bit vs. 64-bit benchmarking over nearly the past decade on Phoronix, the 64-bit version of Ubuntu generally delivers superior performance over 32-bit Ubuntu. This strong 64-bit performance is even when using an old Intel Core 2 Duo system with just 1GB of memory. The reasons for avoiding 64-bit Linux are generally moot these days with Flash, Java, and other applications now running just fine on x86_64 distributions. The state of multi-lib on Ubuntu and other Linux distributions is also in good standing.

This is an interesting question..

32-bit is way ahead as regards to battery life

Ok most people here are focused on raw performance, but having switched back and forth a couple of times since 2007 I now stay with 32-bit on my laptops. On the whole the fact that it consumes less RAM makes it easier on the battery, yet I admit I didn't do a bona fide comparison to see if this would imply more CPU time. As I perceive it, for the usual stuff (office + web, no big games) 32-bit seems more efficient.

I don't think that there's any truth to the statement that 32 bit consumes less power for using less memory. To say that 32 bit applications are more efficient is also false, considering that you have to resort to tricks like PAE to simulate large memory addressing. This argument made a lot more sense in the early to mid-naughties when there wasn't widespread 64 bit support.

I've been meaning to start a thread on power consumption on Linux. I've been shaving milliwatts on laptops for years and it makes for a fascinating and useful topic.

I don't run Linux on a regular basis, but it is much better with 64bit than Windows is.
On a CF52 8gb.. Zorin 64bit is amazing fast compared to 32bit anything...Win 64bit vs 32bit, I could not really see a difference.

I thought the poster was talking more about hardware power consumption..More ram = more power used...More CPU tasks = more power used. Maybe not a significant amount, but it seems to me that power consumption would go up.

The RAM usage issue is sort of a moot point. It would be silly to install 8GB of RAM in a 64 bit laptop and run a 32 bit OS anyway, especially if it's on two 4GB SODIMMs. Obviously it would be preferable to remove the extra 4GB , use it elsewhere and save power that way. And then if you compare running 4GB on a 32 bit or 64 bit OS, I would be surprised to find a difference. I don't know but I'm not finding much logic behind the RAM argument.

But there definitely is an issue with CPU and GPU. That, coupled with I/O and hardware components is where I juggle furiously to eke out as much power as I can. Windows seems to be doing a good job on its own to manage power usage, but it requires a bit of work on Linux. Your choice of desktop/window managers and how you configure them also has an impact. I'll start up that topic next week. ( I promise, lol! )

And you typed this with one hand?

Looking forward to it.

Hopefully not OT:
CF-30 MK3 4 GB 32 bit = 40 seconds from grub menu to work. (Linux fcs85am 3.11-2-686-pae #1 SMP Debian 3.11.8-1 (2013-11-13) i686 GNU/Linux) ((installed on MK2 running on MK3))

Code: Select all

fc@fcs85am ~ $ acpi -V
Battery 0: Discharging, 69%, 04:41:53 remaining
Battery 0: design capacity 8024 mAh, last full capacity 7117 mAh = 88%
Adapter 0: off-line
Thermal 0: ok, 35.0 degrees C
Thermal 0: trip point 0 switches to mode critical at temperature 130.0 degrees C
Thermal 0: trip point 1 switches to mode passive at temperature 90.0 degrees C
Thermal 1: ok, 35.0 degrees C
Thermal 1: trip point 0 switches to mode critical at temperature 105.0 degrees C
Cooling 0: Processor 0 of 10
Cooling 1: Processor 0 of 10

Work in progress:
1. I like quick start and shut-down.
2. I do web browsing/forums mostly/ email via web.
3. One machine set up for netflix. CF-52J LinuxMint 17. SSD
4. Some gps work for mapping.
5. Some radio work via W7.
IOW low power needs.

note: This is the drive I use to test CF-30MK1....NOT the one (of two) I use on my daily worker. Daily worker drives are SSD. One W7, one MakuluLinux-Aero-10 Beta 64bit. CF-30KAPAXAM 14,000 hours +

OT: Shawn you will LIKE the Battery in 31 ATA.

If this is too much information I'll shut up. :)

Jeff, it's all good as long as it's somewhat power related...

I guess the test is two caddies with identical drives and fresh installs..One 64bit and one 32bit...
Then do a power check...Hint..Hint...Hint...:)

I'll have to dig around for a battery meter..Battery bar or battery care..One that runs on windows7 and Linux...
That would give us results from both OS's from the same software..
A bit more of a controlled test..

jeopardy music playing while the search ninja is on a quest..

Batterycare does not have a Linux version..
Batterybar is a no go also..
Mioplanet Battery Meter is a no
