Hi

I have a quad core (4 physical and 4 virtual) multi threading CPU , should i install ubnutu x86 or x64, which would handle the mutiple cores better??

Duh!!

64bit, obviously!!

Not that I've seen any advantages to it. In fact, have come across more disadvantages than anything else. But, if you have it, flaunt it!!

I'd say stick to x64 and learn its advantages and disadvantages. x86 will be faced out anyway. Maybe not tomorrow, but eventually it will. And to be honest, I haven't come accross any real disadvantages of x64 other than certain older hardware which refused to work.

Its 2012. The only reason you should install x86 is if you really REALLY need it.

i though x64 is only AMD architecture!.... will go with x64 \m/ then

Thanks folks

It's called x86_64 most of the time, but AMD64 is what the original instruction set was known as, so it's kinda kept the name >.<

Just be aware, ia64 (for Intel Itanium processors) is a completely different thing, so if you see that ia64 option, avoid it >.< Other than that, x86_64/AMD64/64bit/Intel-64 all the way

Regarding why: All modern 64bit processors emulate 32bit instructions. This means extra overhead in a ton of different ways. Not only that, but you get more registers (computational memory on the processor) and the ability to address more RAM with 64 bit. You also gain some performance with large calculations. Windows is pretty well optimised for x64 instructions, so you gain there as well.

..Yep.
