Who needs the Intel i7 chip?
Here is a question that I recently uncovered. I didn’t find the answer with the question though. For big bonus points, and a gold star – When was the question written?
The Intel clock-doubled 486DX2-66 CPU chip operates by executing a certain fraction x of instructions totally on chip at a doubled rate (66 MHz), while the remaining 1-x are executed at the normal rate (33 MHz). It’s observed that the 486DX2-66 is 76% faster than the 486DX-33 (which executes all instructions at 33 MHz). Given this and making some reasonable assumptions, estimate how much faster a clock-tripled 486DX3-99 (on chip 99 MHz; off chip 33 MHz) is than the 486DX2-66.
