The following section discusses differences between Maya for 64-bit.

Benefits of 64-bit Maya

With Maya 2009 for 64-bit EM64T/AMD^{^®} 64 processors, you can now work with larger and more complex scenes that you ever could before.

Maya on 64-bit can take advantage of greater than 4GB of memory (maximum memory is system-dependent)
Maya on 64-bit uses SSE2 instructions for floating point computations
Additional general registers in 64bit mode allow the compiler to generate better code which spills to memory less often.
