The same applies to open source user applications as well. As Ubuntu is entirely open source, this is not the case as all hardware supported by Ubuntu works equally well in 32-bit and 64-bit environments.

Other platforms which also come in 32 and 64-bit flavours may experience more problems especially due to a lack of 64-bit device drivers as incompatible user application. Some applications such as Flash do run slower in 64-bit mode, however work continues to improve on this. Phoronix has done some testing (2009), comparing 32bit/PAE/64bit, and this seems to indicate that 64bit performs better than 32bit in almost all cases.Įarly 64-bit adopters were plagued by incompatibility problems (most noticeably Java and Flash), however most issues have now been resolved. Certain intensive tasks such as encoding video or audio also run significantly faster on 64-bit operating systems (NOTE: this is implementation specific). If you are doing heavy work where you have started to hit the 4GB memory barrier, then 64-bit is for you.
There's a link provided at the bottom that leads to a full article. Here's some information about arhitectures that you might find useful. At one point in time, manufacturer support for 64-bit drivers was poorer than 32-bit, but this situation is probably the reverse now. Software compiled for 64-bit is usually a little larger due to using 64-bit pointers instead of 32-bit, but that is offset by the ability to use large amounts of RAM - 8GB is cheap and plenty these days and of course can only be fully utilised by 64-bit software.Ħ4-bit operating systems require driver code to be 64-bit. There have historically been some drawbacks to using 64-bit, but these are all but irrelevant now:

Is there any reason to install a 32-bit OS? You can still install a 32-bit operating system and 32-bit software on a 64-bit processor, but it comes with limitations: you won't be able to utilise 4GB or more of RAM (with some exceptions), a single process won't be able to use more than 2GB (usually) of RAM, and you won't be able to utilise many of the new instructions in AMD64/Intel 64 which can potentially speed up programs. Most desktop and notebook CPUs made since this have supported 64-bit, with some exceptions in the early days.
The first Intel CPUs to support the current 64-bit instructions were the Pentium 4F and the Pentium D in 2005, and the first Intel Core CPU to support it was the Core 2 in 2006. The first AMD CPUs to support 64-bit were the Opteron and the Athlon 64 in 2003. Your CPU is 64-bit, as are virtually all desktop CPUs made in the last 11 years.
