I have a few AMD K6 233MHz chips yet not all of them are the same. For instance: this particular model has the regular/common style printed small logo but lacks the engraved MHz-indication and QR-code. AMD added this engraved identification because it makes it more difficult to create false prints. ... > Read more

AMD faced significant challenges with the AMD K5 and nearly went bankrupt. To resolve this, AMD acquired NexGen, a company with engineers some of who had worked on the Pentium. NexGen was developing the Nx586 and Nx686 processors, which are now quite rare. AMD assigned the NexGen team to the K6 proj... > Read more

A somewhat rare AMD K6 because it has a 'big style' K6-logo. Compare with the other related CPU's and see the difference. The difference is only optical. In other words: the chip itself is identical to any other normal K6-233.

As mentioned here I have a few 233MHz-rated AMD K6 chips with slight differences in appearance.

This particular model is made in the 49th week of 1997 and has the regular AMD K6 print with just the QR-code in the left bottom. Older models don't have the ... > Read more

This appears to be a never used (NOS) AMD K6 chip. It runs at 233MHz and also has the engraved speed marking + QR code in the left bottom.... > 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-... > 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... > Read more
