We have two IBM26 6x86-2V2100GB, one with an extra P120+ label, same specs. The third is IBM26 6x86-2V2P120GC P120+ with also the same specs and a square heatspreader. All 3.3V, 0,65µ, 100 Mhz. So are these all same with different labels for marketing reasons or something?
The 2 x 6x86-2V2100GB are both the same core. The second picture is a later production, with the P120+ added to the spec.
The 6x86-2V2P120GC is a later revision, so not the same core. For most code, they all run the same. I can't remember what the core revision is (ie what improvements were made).

Constantly being worked on. Feel free to message me with any corrections or details of cards you would like me to research and add.
Thanks, so I don't need the somewhat overpriced version without the P120+ label for simple test reasons. That's a relief.

Cyrix soft launched the 6x86 in 1995, I remember considering one late that year.
(Pr90) but instead got a retail branded AST ADVENTURE ADVANTAGE 4/66D (less expensive)
The very first 6x86 chips were rated by clock speed only. 80 or 100 mhz
The PR values came later
This is similar to the AMD 486DX5-133 I had, apparently very early before it got relabeled into the 5x86
I had a motherboard with a 40, 45, and 55mhz FSB, it listed support for Cyrix PR90/100/120/133/150
Oddly 45mhz x 2x for PR100 I can’t say I’ve ever seen before.
My guess is they never released that speed grade but it made it into the manual for a few motherboard’s.
