Arcade Games

Did xbox 360 arcade start out with jasper chip set?

I was wondering if the xbox 360 arcade started out with the jasper chip set? Or is there xbox 360 arcades that have other chip sets?
So the ones with the older chip set will be the ones with 512mb memory and the jaspers will have 256mb?

No. They did not start out with Jasper chip sets.
They started with the very first chip called Zephyr or Xenon.
I don’t remember but yea.
The Jasper was started in late 2008 between Oct to December I think.
Correct me if I’m wrong.
Hope this helps.
