Xbox 360 is much smaller than its predecessor--it measures approximately 3.3 by 12.2 by 10.2 inches
and weighs 7.7 lbs. It's powered by custom IBM PowerPC-based CPU with three symmetrical cores
each running at 3.2 GHz. It also carries a custom ATI graphics processor 10 MB of embedded DRAM.
This is powerful enough to draw 500 million triangles per second. In other words, it makes for great looking games
in standard TV definition, and even better thanks to built-in support for HDTV 1080i televisions.
It also supports the widescreen 16:9 format.
