IX Chapter 0010: Summary
In this chapter you learned that the RISC verses CISC battle is now a moot point. You saw the 80486 as the first CPU incarnation with a built-in math co processor, and the marketing of the SX chip being reused to sell CPUs without built-in NPUs.
The battle lines between Intel, AMD, and Cyrix for the lucrative X87 market stepped into a battle for the CPUs market with entries such as the K5 and K6 was shown.
Intel's competitive responses such as Pentium II and MMX being countered with marketing volleys such as 3D-Now and the Athlon family of processors has been outlined to you.
It became clear that as processor speeds went up, voltage to the processor had to come down. You saw the new battle shaping up for the SMP computer systems that will overcome the physical limitations that are being reached in the quest for even more processing power.
Finally the evolution started with Socket 1 and moved through to the wildly popular Socket 7 and the Socket 8 was explained. The dilemma of the Slot based CPU drama was revealed, and you saw the return of the socket with Socket 370 and Socket 462.
