More on Xbox
The custom-designed Xbox 360 central processing unit (CPU) runs at a breakneck speed, thanks to its three separate core processors that clock in at 3.2 GHz each.
Xbox 360 boasts a custom ATI graphics processor that clocks in at a blistering 500 MHz. If you want to get even more technical (and who doesn't?) Xbox 360 can take advantage of more than four times as many polygons as the original Xbox® console, and more than four times (seeing a pattern here?) the number of pixels per second.The 512 MB of RAM in Xbox 360 is eight times more powerful than the original Xbox, in terms of simple arithmetic. The system RAM gives developers a unified memory architecture. Game creators decide how to partition it, and all of the hardware components (like the CPU and GPU) can access the memory.
The HD Era
High definition is upon us, and Xbox 360 is ready. Games are required to be authored for 720p and 1080i, and all games are optimized for the 16:9 widescreen viewing ratio. That doesn't mean you have to have an HDTV to play Xbox 360 games. Xbox 360 games always look good, but they look spectacular on your high-definition display.
The elegantly styled hard drive is physically very small and detachable, but it still boasts a whopping 20 GB of space. The sheer amount of downloadable content that fits on such a hard drive is staggering, and now you can rip more music onto your hard drive and play your own tunes as a soundtrack in any Xbox 360 game.
Xbox 360 utilizes 48 parallel shader pipelines in the GPU that developers can optimize to get the performance they want.. A huge battlefield in Kameo™: Elements of Power™ and a shadow-laden firefight in Perfect Dark Zero™ look completely different and show the diverse ways just one developer, Rare®, took advantage of the GPU's flexibility.
