64-bit

Double the thirty-two

64-bit describes computer architecture that processes data in 64-binary-digit chunks.

A 64-bit processor handles larger numbers and more memory than its 32-bit predecessor—enough to address over 16 billion gigabytes of RAM.

Most modern operating systems and software are 64-bit: You'll need the 64-bit version of Windows.

The hyphen is standard when used as a modifier.
