				History: 
  | 
				
				October 1996 
				133  - 266 MHz 
				16+16 Kb 
				32 Bit 
				64 Bit 
				4.500.000 
				 
				CPGA  
				Boxed versions with / without Cooler
				 
				Black PGA 
				 
				In October 1996 Intel released the 4th Pentium generation as the 
				'Pentium with MMX Technology'. it was based on the 
				standard Pentium core,  but it had a new set of 57 "MMX" (MultiMedia 
				eXtensions) 
				instructions to improve working on multimedia tasks, such as 
				encoding and decoding media. The software must be specially 
				optimized to make use of MMX, and the increased speed the 
				Pentium MMX showed at its apparition was mainly due to the fact 
				that the internal cache had been doubled in size to 32 KB
