copied from http://askubuntu.com/questions...uld-i-choose

I believe the main question when choosing between 32 and 64 bits is not "my processor support 64 bits - should I use this because 64 is "twice better" than 32", but "how much memory do I have".

64-bit programs use about 50% more memory then their 32-bit counterparts. The results of this are:

less code/data can fit into processor caches -> more cache misses -> your super-fast processor waits more for memory controller to fetch data from RAM. Processor also needs to read more data because it's more bloated.

Linux uses non-allocated RAM to cache disks. Less free memory available -> less space for disk caches -> slower disk access

Once you're out of RAM and the system starts swapping - disk access is thousands times slower than RAM, so any potential benefits of 64-bit code (see below) are flying out of window.

On the other hand, in 64-bit mode processor has more registers, so it doesn't need to access memory that often, also, some calculations (64-bit numbers etc.) are more efficient. So generally, code which is not memory-restricted runs slightly faster in 64-bit mode.

So, if your system has, say, 2 of RAM or less then I would definitely choose 32 bits. More than 4GiB - the benefits of 64 bits are becoming more prominent. Around 4GiB is a "grey zone" - you need to make a choice yourself.

Here are screenshots of a (rather old) vanilla Ubuntu running in a VirtualBox with 1GiB RAM:

32 bit: uses 388 MiB of RAM right after booting, no additional applications running (from the screenshot, 397780KiB, which is 388MiB)

32 bit Ubuntu

64 bit: uses 491 MiB of RAM (from the screenshot, 503452KiB = 491MiB)

64 bit Ubuntu

Additionally, in my testing, a web-application written in Python used up to 60% more memory on a 64-bit machine which resulted in a test suite running in 380 secs on a 32-bit machine but taking 523 seconds on a 64-bit one (both with 1GiB of RAM). If the machines were not RAM-limited the results would likely be different (as phoronix tests show).

Here are some more thorough and recent tests: http://kernel.ubuntu.com/~ckin...parisons.ods

mem free mem used swap used

Basically, it's like giving up 30% of your RAM in exchange of possible gain of 10% CPU speed.

These paid reviewers from Samsung are pathetic.

I should get the Sony Xperia Z 1, definitely better than 4s in terms of cost to performance.

I dont think Apple wants to spend so much money to make a factory just to manufacture one chip a year. thus contract it out to someone else which is Samsung.

64bit CPU's anyone remembers what happend on Pc's applications were not all compatible.. but that will quickly change.

I played with the 5C yesterday i like it but still prefer my S4 when it comes to typing and editing your typing if needed its a bigger phone thats mostly why i enjoy it. (big hands).

I think Apple could of at least clocked it a bit higher dont you guys think.. minor difference in the clock speed sure the CPU is more powerfull especially on 64bit but just for the dumb consumer will only see it as oh 1.3 only.. mmm

But apple fans will go take my parents money etc :P
or Blackberry customers will just buy them for a change and be different from the millions that left for Samsung (Way too many)

Im just thinking about the result of the test!. Why there is no competitor like z1,G2,note 3? why all the competitor is all late produce smart phone and take note all the competitor is 2012 product produce HELLOO!!! IPHONE this year is 2013 LAST QUARTER!? is this mean that the innovation of the IPhone after the death of the fonder does not move anymore? and there engineer is still thinking? until now? so there innovation is like turtle now? im not posting this to ruin all of your post. im just a concern citizen to those people who love Iphone product.

To make a chip, u need a big design. in this case, Apple designs A7 64bit (which is Samsung don't have 64bit processor) and then send it to samsung to made it. If samsung doesn't exist, apple'd found another manufacturer.

Okay, samsung has it own chip, but they don't have use it. They prefer to use snapdragon by qualcomm

And Exynos is the fastest cpu out there. The last gen Exynos beats Snapdragon 600 in almost every benchmark. Same thing will happen with the latest Exynos, it will beat the Snap 800. And that's even before the update to enable it to become a true octacore. So what are you laughing at? Yourself? Lol

And my statement was regarding exynos.
