You can't think of improvements since the worlds first microprocessor?
- Intel 8086, the first 16-bit microprocessor (around 1976)
- Intel 286 (around 1982) , it doubled the power of the 8086. A jump like that has never been duplicated since!)
- Intel 386DX (around 1985), doubled the speed of the 286 up to 20MHZ. It was Intel's first 32bit processor.
- Intel i486 (around 1989) was the first chip to have a built in math co-processor. Boosted processing speed up to around 50MHZ
- around here was where the battles started between Intel and AMD
- Intel Pentium (around 1993) Introduced the 64 bit data bus. Boosted processing speed to 233mhz
- Intel Pentium Pro (around 1995) brought the transistors up over 5 million and added an L2 cache
- Intel Pentium II (around 97, 98) moved the cache off to an additional chip, reducing the price of the chips. Chip is now around 7.5 million transistors and able to handle around 64gb of memory.
Intel Celeron, Pentium III, Pentium 4, Pentium D (now 2 cores on one chip), Core 2, Core i7.........
Speed, processing power, memory utilization......I am not sure how you could not come up with some examples of major improvements since the 4004?!?
