CPU history back to back: Intel vs AMD

It is about the modern processor history, mind you, the one since 1970s until now, not the one from 1826, when the differential engine was built or since 1600s, when a tax calculator was devised by Pascal or from way back before when the Chineze were using the abacus.

Intel first launches the 4004 CPU and then the 8086 with x86 architecture. After this it launched the 286, 386, Pentium I and so on.

Intel highlights:
– Intel 386dx = first to use 32 bit X86 processor, 33MHz, 4 GB RAM
– Intel Pentium = first to add MMX, multimedia extension
– Celeron 300A = first to let you overclock the processor
– Pentium III = speedstep, run the CPU at lower speeds when idle, add L2 cache, first over 1GHz
– 2002 = added hyperthreading technology
– 2004 = LGA type socket, contact pins on the motherboard, not on the CPU chip
– 2006 = Core Duo and Quad see the daylight, the end of “Gigahertz war”, added virtualization and turboboost, onboard videocard
– since then 10-15% improved performance each passing year

Now, AMD started by copying Intels 8080 processor, but then moved on to creating their own CPU and also developing X64 processors which them they licenced to Intel in order to further fuel the CPU wars:

AMD highlights:
– 1974 = AM9080 was a clone of Intel 8080
– 1976 = Intel licenced to aMD the X86 architecture
– 1996 = AMD K5 designed to fight with Pentium I
– 1997 – 1998 = AMD K6-2 captured a good chunk of the PC market
– 1999 = AMD K7/Athlon, first to run at 1GHz, used the PR rating system like 1900+ (relative to Intel processor speeds)
– 2003 = AMD lunches X86-64 architecture in K8 series (64bit processors)
– 2005 = multicore processing
– APU, FX series is created = APU has added video on board, FX for gaming, comparable to Intel
