Silicon Discovered
Baron Jons Jackob Berzelius
Created when heating sand to 2200 degree Celsius.
Used to make computer processors, chips, boards, etc. (anything to do with a computer, has silicon) -
electrical logic circuits
Nikola Tesla
Gates and Switches.
And/Or circuits - in order for a light to come on, all 3 switches have to be on. OR, 1 of 3 switches have to be on. -
Invention of the Transistor
John Bardeen, Walter Brattain, William Shockley
switch than can be either on or off (0 and 1)
Used in every computer processor
amplify, control, and can generate electrical signal -
first working integrated circuit (IC)
Robert Noyce, Jack Kilby (Dummer was first person to conceptualize and build a prototype)
Air Force computers
was a transistor that took up less space and worked better -
Moore's Law
Gordon Moore
number of transistors on a computer chip were doubling every 18-24 months - eventually changed to every 2 years
transistors shrink in size by 1.7 every generational leap - still holds true
Eventually, they will be so small, the electricity will jump over the gate -
Intel 4004
Ted Hoff and intel.
2,300 transistors, 60,000 OPS, $200
first microprocessor
general purpose CPU for calculators, cash registers, ATMs.
Until now, computers were large servers that were filled with transistors and ICs -
Intel 8008
Intel
8-bit, 100,000 Instructions per second
supported more, faster memory
used in Mark-8 computer (first personal computer) -
Intel 8080
Improved 8008 - faster - standard in computer industry - intel becomes THE company in computer processors
later swapped with intel 8085, 8088 -
AMD AM386
Intel is no longer the only one in the processing market
starts the race for faster clock speeds (higher IPS) -
Megahertz race
Intel and AMD and constantly making CPUs that have higher megahertz (ISP) Intel Pentium/Celeron vs AMD K series and Athlon series -
Intel Pentium D/AMD Athlon X2 3800+
Dual core processors are now real. Ends the megahertz race in favor of more cores and more ISP. Intel kept the Core 2 Duo or Core 2 Quad naming scheme. AMD had Athlons and Phenoms. -
Intel Core i7
issued in a new era of Intel dominance. AMD remained competitive with their Phenon line and A series and later bulldoze (FX) processors -
AMD ZEN arcitecture
AMD didn't beat intel in single-core performance, but they had 8 cores 16 threats compared to Intel's 4 cores 8 threads (on the i7s)
AMD became competitive again.
Started a stream of good things for AMD (zen 2 and zen 3) which has put AMD on top
Intel is now struggling to compete with AMD (they sat on top for too long)
