FAQ

What is x64 and why is it different to x86?

x86 is the common term for the instruction set that is used in Intel's CPU family inlcuding the 80286, 80386, 80486, Pentium, Pentium II, Pentium Pro, Pentium III, Pentium 4. It is also used to refer to all CPU that are compatible with these processors. x64 refers to processors that are compatible with the x86 instruction set but have extension commands that enable access to 64-bit of address space, thus removing the 4 GB memory limit of the older x86 processors.

What is Sun Fire x64 servers?

Sun Fire x64 is the family of servers from Sun Microsystems that are build using processors that implement the x64 instruction set. Currently Sun Fire x64 servers only use AMD Opteron processors.

What is the difference between non-M2 and M2?

Non-M2 systems use AMD Opteron Revision E processors, M2 systems use Revision F processors. Rev F processors are socket compatible with the upcoming Opteron quad-core processors which means that the M2 systems are upgradeable via swapping the CPU.
