For the most part you will not notice a difference but for large workloads (such as video editing, gaming, etc), the computer will perform faster (the computer has the ability to calculate 2+2+2=6 instead of having to do 2+2=4+2=6 in an example). x86-64 is still used by many in the industry as a vendor-neutral term, while others, notably Sun Microsystems (now Oracle Corporation) and Microsoft, use 圆4.Įven if you have an intel CPU, you should use AMD64 to install 64-bit on your computer (it uses the same instruction sets). After launching the architecture under the "x86-64" name, AMD renamed it AMD64. It supports vastly larger virtual and physical address spaces than are possible on x86, thereby allowing programmers to conveniently work with much larger data sets. X86-64 is an extension of the x86 instruction set. This is termed x86, IA-32, or the i386-architecture, depending on context. The Intel 80386, also known as the i386, or just 386, was a 32-bit microprocessor introduced by Intel in 1985. I386 refers to the 32-bit edition and amd64 (or x86_64) refers to the 64-bit edition for Intel and AMD processors.
