This page will show all objects that classify as AMD K6. The K6 has been made by Advanced Micro Devices, a multinational semiconductor that develops microprocessors, chipsets and graphic processors (ATi). AMD is the second largest microprocessor manufacturer after Intel and has active since 1969.
In 1982 AMD signed a contract with Intel to become a licensed second-source manufacturer. IBM wanted the Intel 8086/8088 but IBM's policy stated that at least two suppliers should be available. This is why the first AMD processors always have 'Intel' printed somewhere. After a while AMD didn't get the license to produce Intel processors anymore and thus AMD started cloning the 386 and launched the Am386. Since the AMD K5, AMD didn't clone the Intel processor but started developing on their own. The K5 wasn't a big success but thanks to NexGen that merged into AMD the K6 could be made. AMD could compete and has a range of processors today including six-core Opterons and a good performing quad-core for the desktop called the Phenom II X4.
AMD also acquired ATi to get in-house graphics chips. These are integrated in chipsets to create cheap motherboard solutions. In the future (The Future is Fusion as AMD calls it) the plans are to integrate the graphics chip into the processor.
AMD K6 166ALR '25755'
AMD had lot's of trouble with the AMD K5 and nearly went bankrupt. To find a way out they bought NexGen (which also had engineers that worked on the Pentium) that was developing the Nx586 and Nx686 which are quite hard to get these days. AMD put the NexGen team on the K6 project and let them build the CPU. The result was a decent CPU that could compete with the Pentium and that was compatible with socket 7 motherboards. Because of this AMD didn't have to worry about motherboards. > Read more
Just like the 166MHz model but somewhat faster. > Read more
Just like this AMD K6 166ALR but then faster and hotter. The AMD K6 233 runs like hell if it comes down to integer performance (which you'll notice in Doom and Windows) but is somewhat poor with floating point (FPU) calculations. In case you want to play 3D-games like MDK or Quake the AMD K6 was not the CPU you wanted. Compare the K6 233 with the Pentium MMX 233 for example 
.
The heatspreader of the K6 233 indicates the CPU needs 3,2V to run correctly. 3,2V is more than the Pentium MMX or the K6 166. It looks like AMD had problems reaching higher clock frequencies and increased the default voltage in order to maintain stability. Although my QDI Explorer II DM250 motherboard did not support 3,2V for the AMD K6 it ran just fine at 2,9V. Maybe I was lucky.
There is also an AMD K6 233AFR which uses 2,2V and has been made with a 250nm process. > Read more
Although the codename of this CPU is 'Little foot' it isn't just the same as the AMD K6 166, 200 and 233 with ANR. This one has been made on 250nm and uses 2,2V. Performance would be equal to a 266MHz 'old' Little foot but heat generation is far less. Because of this AMD could also crank up this CPU to 300MHz. > Read more
