The Xbox 360 was the first home console to be released in the seventh generation of game consoles and competes against Sony's PlayStation 3 and Nintendo's Wii.
John Carmack stated at QuakeCon 2005 that the Xbox 360 has "the best development environment I've seen on a console".
Microsoft XNA also includes other components such as the XNA Framework and XNA Build. Anyone can develop a game using XNA Game Studio Express, an IDE for homebrew developers, which was initially released in beta form on August 30, 2006.
The console features 512 MB of 700 megahertz GDDR3 RAM on a 128-bit bus.
