steve, Interesting but vague comments on xbox.com.
I see the have an expansion port? Makes me wonder if they have arranged a special on board mount for the Athlon they will be using? My reasons are they will want to avoid the cost of both parts of the slot A package and one way to save $30+ is to do that, and for the many million market of the xbox the xost saved will be huge and AMD wants to transition to a socket. Thus will this Athlon be one of the ones with onboard full speed cache? needed for games and needed for AMD beat out the P-III? In addition they will want to make a low profile box so the expansion port will be a back edge connector of some kind to go to an expansion box......or one flat lying slot to take one card? In addition they may want to externalize the power supply into a remote switcher to save more bucks with possibly PWM power distribution in the box. What power will a 600 Mhz Athlon use in .18? is that compatible with an external power transformer? Many lap tops have external switching power supplies at ~12V 3=4 Amps. Possibly an xbox will need 12V % 4-5 Amps, this will then power the DVD and HDD and be high efficiency PWM downregulated to run the logic and CPU. That means the external power supply will run efficiently and there will be no long runs of 1.6 volt at high amps, just 12V at 4-5 Amps.
This is all speculation based on the driving need for low cost in the games market.
