GAF... A technical question:
Based on the 'supposed' specs.... how small could the console be and will it have a power brick?
Well we dont know, but the specs dont really suggest a small console.
In fact I believe someone claimed to know Durango has a 220 watt PSU, larger than 360 on launch. This was months ago too (which makes it pretty suspect how somebody would know that, but anyway)
There's is going to be a lot of stuff in there that draws electricity, even like USB ports and the Blu Ray drive and Kinect. I'm not saying it's a hog, but dont expect anything substantially smaller than a launch 360 imo.
Along those same lines I personally would definitely bet on an external brick as well.
FWIW the TDP of a 10 CU 1000mhz AMD GCN HD7770 (~1.2 TF) is 80 watts. That would include 1GB GDDR5.
The old rumors put Durango GPU at 1.2 TF, but by way of 12 CU's and 800 mhz. So it should draw less power, maybe 70 watts?
This oldass table
http://www.geeks3d.com/20090618/graphics-cards-thermal-design-power-tdp-database/ claims a 7800GTX drew 81 watts. A 7800GTX ~RSX which ~Xenos. So I think we can assume the same.
So by that you might be in the area of 360 power draw, but I really cant say, maybe an 8 core Jag draws significantly less than the old 360 CPU.
