Microsoft Xbox 360 Specs: CPU, Graphics, Memory

These are the official specs of the Xbox 360 directly from Microsoft before the system launched in November 2005. Some aspects of the hardware have changed in the decade since, such as the addition of an HDMI port, built-in Wi-Fi, support for 1080p, and two total redesigns of the system—the Slim system and later the "E"—but the core of the hardware hasn't changed much from this initial spec sheet.

It is pretty impressive how a system that was underpowered to begin with compared to its competition (the PS3) is still alive and kicking and pumping out good-looking games even today.
