What the reviews said:
It’s not a Palomino.
All those mentioned in reviews have AXIA codes.
They perform a bit better than the 1200s.
What else you need to know
Since these are AXIAs, you don’t need to buy a 1300 or 1333 to get one, just look around for a lower-rated chip with the same code.
Since we already have some experience with how they behave, here’s a few more points to consider:
Get serious about cooling: If you spend $300 on this chip, don’t try to save $10-15 by using the AMD retail fan or something else cheap, then ask us, “Why doesn’t this overclock much?” It probably doesn’t overclock much because you tried to save $10-15. Don’t match up a world-class processor with a Mickey Mouse heatsink fan. If you’re going to go first-class, go all the way.
A wee bit more voltage may help: Obviously, this is adding fuel to the fire, and any mobo mods are strictly your responsibility, but provided you are using top-notch cooling, 1.9 or 1.95V may get you over the 1500Mhz hump.
Peltier Friendly: Earlier generations of TBirds were rather unreceptive to chilling. These seem to get more of a boost out of it. No miracles, but 100-150Mhz improvement doesn’t look to be out of the question.
