AMD has long been subject area of polarizing debate among engineering science enthusiasts. The capacity of its history provide ample ammunition for countless discussions and no modest measure out of rancour. Because that it was once considered an equal to Intel, many wonder why AMD is declining today. However, it's probably fairer to enquire how the company has survived then for long -- a question nosotros intend to explore as we revisit the company'south past, examine its nowadays and gaze into its futurity.

Editor's annotation (from the hereafter): Well-nigh a decade later, we've revisited AMD'south history to practise a follow upwardly of this feature, read the latest version called:
The Ascension, Fall and Revival of AMD

AMD's Ascension

Founded in May 1969 by seven Fairchild Semiconductor employees headed by Jerry Sanders, Fairchild's manager of marketing, you could say AMD established itself as an underdog from the showtime by focusing its early on efforts on redesigning parts from Fairchild and National Semiconductor instead of creating new products as Intel did with the iconic 4004. Though it came close during the early 2000s, as we'll talk over soon, the company has largely struggled to shake the prototype of existence Intel's shadow.

Back to 1969, a few months after its creation, AMD moved from Santa Clara, California -- Intel'southward hometown -- to Sunnyvale, bringing with information technology redesigned integrated circuits (ICs) that touted increased efficiency, stress tolerances and speed. AMD designed its chips to meet US military specifications, which proved a considerable advantage in the nascent computer industry where quality control varied extremely. Pattern and production of logic ICs connected to grow steadily.

Past 1975, AMD grew to be a sizeable visitor. That twelvemonth saw the introduction of the Am2900 IC family unit, which included multiplexers, ALUs, system clock generators and retention controllers -- private IC blocks that are now plant in modern CPUs, but were split integrated circuits at the time. AMD also began opposite applied science Intel's 8080 processor. Originally called the AM9080, it was renamed 8080A after AMD and Intel signed a cross-licensing understanding in 1976. Cost for AMD: $325,000 ($ane.3 million in today'southward dollars).

AMD took over five years to reverse-engineer the 80386 into the Am386, but once completed information technology once again proved to be more than than a match for Intel'due south design.

The 8085 (3MHz) processor followed in 1977 and was soon joined by the 8086 (8MHz) likewise equally the 8088 (five-10MHz) in 1979, a year that also saw production begin at AMD's Austin, Texas facility. Early 1982 ushered in a new stage of the company. When IBM began moving from mainframes into PCs, the outfit decided to outsource parts rather than develop in-house. Intel's 8086 processor was chosen with the proviso that AMD acted as a 2nd source to guarantee a constant supply for IBM's PC/AT.

A contract was signed in February 1982 between Intel and AMD, with the latter producing 8086, 8088, 80186 and 80188 processors, not just for IBM, only for the many IBM clones that proliferated -- notably Compaq. AMD also started producing the Intel 80286 as the Am286 well-nigh the terminate of the year. This was to become the first truly significant desktop PC processor, and while Intel's models generally ranged from 6-10MHz, AMD's started at 8MHz and went as high as 16-20MHz -- a blow confronting Intel.

This catamenia represented a huge growth of the fledgling PC market place. Noting that AMD had offered the Am286 with a significant speed boost over the 80286, Intel attempted to stop AMD in its tracks past excluding them from the side by side generation 386 processors. Arbitration took four and a half years to complete, and while the judgment found that Intel was non obligated to transfer every new production to AMD, it was determined that the larger chipmaker had breached an implied covenant of good faith.

Intel denied AMD access to the 386 license during a disquisitional menstruation when IBM PC's market share grew from 55% to 84%. Left without admission to Intel's specification, AMD took over v years to reverse-engineer the 80386 into the Am386, just one time completed it over again proved to be more than a match for Intel's design. Where the Intel 386 reached 33MHz, the Am386DX striking 40MHz, endmost in 486's performance. This was probably the first instance of AMD notoriously offering a better performance/price ratio.

The Am386'southward success was followed past the release of 1993'due south highly competitive 40MHz Am486, which offered roughly 20% more operation than Intel's 33MHz i486 for the same toll. This was to be replicated through the entire 486 line up, and while Intel's 486DX topped out at 100MHz, predictably at this phase, AMD offered a snappier 120MHz pick. To better illustrate AMD's good fortune in this period, the company's revenue doubled from just over $1 billion in 1990 to well over $ii billion in 1994.

In 1995, AMD introduced the Am5x86 processor equally a successor to the 486, offering it as a direct upgrade for older computers. The Am5x86 P75+ boasted a 150Mhz frequency, with the "P75" referencing operation that was similar to Intel's Pentium 75. The "+" signified that the AMD chip was slightly faster at integer math than Intel's solution. Intel had switched naming conventions to distance itself from products by AMD and other vendors. The Am5x86 was an great revenue earner for AMD, both from new sales and for upgrades from 486 machines. As with the Am286, 386 and 486, AMD continued to extend the lifespan of the parts past offering them equally embedded solutions.

March 1996 saw the introduction of its first in-firm processor, the 5k86, after renamed K5. The chip was designed to compete with the Intel Pentium and Cyrix 6x86 series. Executing well with the K5 was a pivotal point in AMD'south history since the chip had a much more powerful floating point unit than Cyrix's and about equal to the Pentium 100, while the integer operation equaled the Pentium 200. Unfortunately, the project was indomitable with pattern and manufacturing issues that resulted in the CPU not meeting its frequency goals, arriving late to market and suffering poor sales. Opportunity missed.

AMD'southward ascent mirrored Intel's decline from the early ancestry of the K6 architecture, which was pitted against Intel'due south Pentium, Pentium Ii and (largely rebadged) Pentium Iii.

By this fourth dimension, AMD had spent $857 million in stock on NexGen, a modest fabless chip company whose processors were fabricated by IBM. AMD's K5 and the developmental K6 had scaling issues at higher clock speeds (~150MHz and in a higher place) while NexGen'southward Nx686 had already demonstrated a 180MHz core speed. Afterwards the buyout, the Nx686 became AMD's K6 and the developmental (original) AMD "K6" was consigned to the scrapyard.

AMD'due south ascent mirrored Intel's turn down from the early beginnings of the K6 architecture, which was pitted confronting Intel'due south Pentium, Pentium II and (largely rebadged) Pentium 3. The K6 produced a quickening of AMD'south success. The CPU owed its beingness to an ex-Intel employee, Vinod Dham (a.m.a. the "Father of Pentium"), who left Intel in 1995 to work at NexGen. Dham was instrumental in creating what would become the K6.

The arrival of AMD's K7 (usually known by its model name of Athlon) in 1999 represents the height of the company's golden age.

When the K6 hit shelves in 1997, it represented a viable alternative to the Pentium MMX, and while Intel connected to stumble along with its underwhelming Netburst compages, the K6 went from strength to force -- from a 233Mhz speed in the initial stepping, to 300MHz for the "Little Foot" revision in January 1998, 350MHz in the "Chomper" K6-2 of May 1998 and 550MHz in September 1998 with the "Chomper Extended" revision. K6-ii introduced AMD's 3DNow! SIMD Instruction set (similar to Intel'southward SSE), though this came with the downside that programmers needed to contain the new instruction in addition to patches and compilers needing to be rewritten to employ the feature.

Like the initial K6, the K6-II represented outstanding value, often costing half as much as Intel'due south Pentium chips. The final iteration of the K6, the K6-Three, was a more complicated CPU, the transistor count now stood at 21.4 million -- up from 8.8 million in the beginning K6, and 9.4 million for the K6-II -- and incorporated AMD's PowerNow!, which dynamically contradistinct clock speeds according to workload. With clock speeds eventually reaching 570MHz, the K6-III was fairly expensive to produce and had a relatively short life span cut short by the arrival of the K7 which was better suited to compete with the Pentium III and beyond.

The arrival of AMD's K7 (commonly known by its model proper name of Athlon) in 1999 represents the tiptop of the company's aureate age. Starting at 500MHz, Athlon CPUs utilized the new Socket A and a new internal system charabanc licensed from December that operated at 200MHz, eclipsing the 133MHz Intel offered at the time. June 2000 brought the Athlon Thunderbird, a CPU cherished by many for its overclockability, which incorporated DDR RAM back up and a full speed L2 on-dice enshroud.

Thunderbird and its successors, Palomino, Thoroughbred, Barton and Thorton, battled Intel'due south Pentium 4 throughout the first five years of the millennium, usually at a lower price point. Athlon was joined in September 2003 past the K8 (codenamed ClawHammer), better known as Athlon 64 because it added a 64-flake extension to the x86 instruction set up.

This brief episode is unremarkably cited as AMD'south defining moment. While AMD was surging, the speed-at-any-cost approach of Intel's Netburst architecture (particularly with the Pentium iv family) was beingness exposed every bit an exercise in hubris.

So, what happened? Why didn't AMD continue on the path to greater celebrity? This is more often than not where the heated fence starts...
