Intel's 5th generation of x86 line of processors.
The Pentuim MMX line of processors is binary compatible with older generations of x86 processors
and has the following enhancements over the previous generation of x86 processors (80486):
- Binary compatible with older generations of x86 processors.
- Branch prediction. Branch prediction was further enhanced in comparison with Pentium processors.
- Dual processor support.
- Superscalar architecture (2 pipe-lined integer units + 1 pipe-lined FPU).
- FPU performance enhancements.
- Power management features.
- Separate 16 KB code and 16 KB data cache (Pentium non-MMX process had 8 KB code and 8KB data cache).
- 3.3V input/output level and 2.8V core.
- New 67 MMX instructions and 4 new 64 bit data types.

Boxed version of Pentium MMX processor. These processors were sold with integrated heatsink and fan, which, coupled with Zero-Insertion Force (ZIF) sockets, made processor upgrade much easier. Markings on these CPUs were on the heatsink below the fan, under normal conditions (with fan installed) the markings are not visible. But even then it's still possible to tell the processor speed by looking in the left-lower corner of the CPU - the number in this corner is the speed of the microprocessor in megahertz.
