what is the difference between x86_64 amd64 and 64 bit ?
I think its a stupid question but still.
I use a x86_64 bit Ubuntu, but when ever I try to do a live boot of any other 64 bit images like the gnome 3.16 released yesterday it does not work ?
Also some times when I try a virtual machine of a 64bit image it does not work either.
What is the reason for the same ?
My laptop model is an Hp Pavillion dv4 1506tx.
The processor is 2.20 GHz Intel Core 2 Duo Processor T6600
This may not solve exact problem, but I'll clarify the difference between x86_64, amd64 and 64-bit.
Every micro-processor implements an instruction set (also called instruction set architecture or ISA in short).
64-bit ISA or 64-bit processor means that the length of each instruction that the processor executes is 64 bits.
x86_64 is name of specific 64-bit ISA. This instruction set was released in 1999 by AMD (Advanced Micro Devices). AMD later rebranded it to amd64.
Other 64-bit ISA different from x86_64 is IA-64 (released by Intel in 1999).
