So, I need to learn and expand my collection with some K6's thus knowledge Laughing


Which K6-2 are Chompers' and which are CXT's? The info section here is not 100% conclusive?

The story is, I'm making a sheet with the different varieties, to be able to check, which I have, and which I'm missing ..

Check CPUID with e.g. cpu-z.
580 - Chomper
58C - CXT
Also CXT interprets multiplier 2.0 as 6.0.
All 366 and above should be CXT.
Also there is correlation with package number:

Well, problem is, I need to map out, which variants are made, so I need which ones to have ..?

Given the info in that old thread - which I can see is partly info from Wikipedia, but can I expect those to be correct, i.e.;

Chomper: 233, 266, 300, 333, and 350
CXT: 266, 300, 333, 350, 366, 380, 400, 427.5, 450, 475, 500, 533, and 550

Thus 266, 300, 333 and 350 can be both?

Thanks for that very comprehensive list!

I'd guess that any K6 3D would be Chompers, as the name changed to K6-2 rather soon after launch?

And I don't get what you mean by the note I've colored red. Chompers was AFAIK never a K6, but always K6-3D or K6-2?

Back in the day, I actually didn't know that K6 was made in 300 - I thought it was only the K6-2 .. Smile

Oh, and by the way - does the K6 core in 350nm have a name - the 250nm is LittleFoot, but what about the original?

I would also guess that K6 3D would be Chompers.

The note in red pertains to a few K6-300, which is not what you asked about, but I thought maybe interesting. I guess that some of the Chompers silicon was used to fill demand for K6 chips?

I have not seen a nickname for 350nm K6. It's a strange absence.

Yeah, that would make sense, of course ..

So, I have this 350 in 26050 packaging - but no way to know whether Chompers or CXT without using CPUID?
