Xbox 360 CPU Possibly Going 45nm in late 2008, early 2009

Illustration for article titled Xbox 360 CPU Possibly Going 45nm in late 2008, early 2009

We still haven't gotten 65nm Xbox 360 processors, and there's already talk of Microsoft's contracted Singaporean chip manufacturer moving on to designing 45nm CPUs for gaming devices. Why is this important? Because the smaller the CPU fabrication size is (90nm vs 65nm vs 45nm), the less power it takes to run and the less heat it generates (theoretically).


The same Singaporean chip manufacturer, Chartered Semiconductor Manufacturing, has been making 65nm chips for two quarters now. This probably means Xbox 360s will go 65nm fairly soon, but will have to wait about 18 months or so to get to the 45nm threshold. Will it actually make a difference? From what we heard, most of the overheating problems came from the GPU, not the CPU, which is what lead to the added cooling in the Elite version recently. [PCAdvisor]

what are yout talking about? the overheating issue has been resolved, have you even seen the inside of the new 360's and the repaired 360's they have massive new heatsinks and heatpipes, which i personally think end up as overkill considering my day 1 360 still runs flawless along with my brother and 2 of my friends all that have launch day consoles that are fine....

add to that the fact that the new and repaired 360's have the huge new heatpipe and heatsinks i believe the problem has been solved.

As for the move to 65nm thats happening this year in the coming months and later to 45nm next year and into 2009, thats not to solve a problem... its to CUT COSTS, the smaller the chips the less they cost and bigger the yeild so the 360 can drop in price further.

And even after they've added the new heatsinks heatpipes and eventually the smaller dies, the 360 will still be the only console with a 3 year warranty.
