This is still 65,536 times larger than the virtual 4 GiB address space of 32-bit machines. Intel 64 is Intel's implementation of x86-64, used and implemented in various processors made by Intel. None of Intel's earlier notebook CPUs (Core Duo, Pentium M, Celeron M, Mobile Pentium 4) implement Intel 64. The 8086, 8088, 80186, and 80188 can use an optional floating-point coprocessor, the 8087. [11]:11 However, such programs may be started from an operating system running in long mode on processors supporting VT-x or AMD-V by creating a virtual processor running in the desired mode.
