AMD used to manufacture CPUs for intel (who couldn't make enough for the demand).
AMD made their 286 & 386 clone type cpus. The 486AMDs were quite good (And the Cyrix 486-true totally kicked butt).
(A Cyrix 100Mhz was cool enough to touch - back when 66mhz 486 cpus were hot enough to burn your skin off, they out performed AMD & intel at same clock speed and were easily overclockable. Cyrix lost it on the 586 series of chips)
Intel stopped making x86 named chips because of Cyrix and AMD.
AMD bought NEXGEN (who made a custom RISC>x86 cpu/mobo combo) NexGEN had a very good product with an unheard of 3-5 year warranty. The cpu-board combo is a double edge sword. 1 - No way to selll the CPU as the chip was incompatible with ALL mobos. 2- reliable was HIGH because there were made for each other. 3- upgrades are bad since you bought a packaged deal. 4 - no future.
AMD used NexGEN technology in the x586 cpu - these were the PRE K6 processors. They were OKAY - but not reliable. The K6 chips were FINE office CPUs. But even the K6-2 & K6-3 were never able to equal PII or Celeron 300A performance that games needed. ie: A 333mhz Celeron woul easily KICK the AMD K6-2 450Mhz in 3D games. For 2D desktop, it was the reverse in many cases.
Most K6-2 systems were crap due to the cheaper chips being installed in yet cheaper hardware. (PCChips comes to mind) Stick a P1 or P2 into a CHEAP junky mobo and you'd get an unstable system as well.
While I personally had high hopes for the Athlon CPUs (because I was getting tired of intels games and high prices), I didn't adopt the AMD cpu for the first 2 years due to reliability and stability issues of the mobos and some odd-ball performance issues. The first AMD systems I built was when the TBird-1ghz was NEW and had to upgrade a customers PC who bought a POS SLOT-A board from another vendor. But I still built P3s and Celeron systems as the primary.
When the KT-266A chipset came out (as well as the XP CPUs), I never built another intel system since.
Great summary.
I'll point out a few significant moments in AMD history. This is purely from an enthusiasts point of view.
Intel trademark's "Pentium", and eliminates AMD and Cyrix ability to "clone" X86 CPU's
AMD uses the 5x86 (133MHz 486) part to compete with the >100 Pentiums because their 5th generation core wasn't primetime. (although having a 486 overclocked to 160MHz was badass)
AMD releases the K5 with confusing PR rating. Same speed chips have 2 different ratings. K5 never mattered much, as they ramped clockspeeds way too slow to compete with Pentiums.
Nexgen based K6 becomes the foundation for real competition for Intel. K6 233 is fastest desktop processor for about a week until...
Intel moves to slot-1 Pentium2 design with on-board L2 cache. Performance kills the k6. AMD responds with faster K6's and the dubious Super Socket 7 platform. This pushes VIA into limelight, albeit with a buggy MVP4 chip. K6-2 with 100MHz bus and 3dnow shows it can outperform P2 in a couple highly AMD optimized benchmarks.
Intel creates Celeron 300A with on-die cache. Many users who stuck with AMD because of high intel prices ditch AMD for this price/performance and overclocking champ.
K6-3 offers improved performance, but flounders. The k6 architecture has just too weak of a FPU to compete with Intel and 3dnow adoption is slow. "Pentium" becomes the "kleenex" of microchips.
Highly anticipated K7 platform emerges, initial motherboards are buggy, high PS requirements. The biggest CPU battle in history is born. AMD Athlon and Pentium 3 race to 1GHz... with AMD winning (sorta).
Both AMD and Intel move to socket platform. VIA has become a viable (pardon the pun) alternative to Intel based motherboards. Many question stability, but many more actually buy the boards.
AMD Duron brings $40 good performance chips to the mainstream. KT133A motherboard is a big win for VIA. Many of those 300A/BX users find themselves switching to T-bird/KT133A platforms. Intel BX motherboard is tough to beat though. "The Pencil Trick" becomes common language for PC tweakers.
In a move some believe was driven entirely by marketing, Intel moves to a long pipe, high clock design Pentium 4. Initial parts perform poorly compared to AMD, but the ball is rolling. AMD remains the enthusiast choice for price/performance and stays strong in the overall performance category until the Northwood P4 emerges.
P4 1.6 is new Celeron300A, almost. Intel captures performance crown by using RDRAM, which everyone loves to hate. Eventually DDR wins. Athlon XP and KT266A is awesome price/performance vs Intel, but AMD is losing at overall performance to high clocked P4's w/ DDR.
Today...
everyone waiting for Barton, Hammer. Intel is showing 3GHz, while AMD plays "PR" games. AMD paper launches XP2400, 2800. AMD still value pick.
I probablky left a ton out, but that's my $0.02
edit ---
just so no one thinks i was harsh on AMD, i've been using/abusing their parts since 386DX40, 486DX4-120, 5x86133, k6200/TX then moved to 300A/BX, Celeron 533/BX, Athlon 800/KT133, I seem to be stuck on this Tbird 1.3/Kt133. Waiting for dasm nForce2... might end up back at intel
