How IT Work ?
27
Microsoft's first video game console, the Xbox,
sold more than 20 million units worldwide since
it was introduced in 2001. Despite the Xbox's
impressive power, the list of big-name video game
titles to support it and the success of the
Xbox's online component, Xbox Live, the console
was still outsold considerably by Sony's
PlayStation 2. As the game industry moves
toward the next generation of video game
technology, Microsoft wants to make sure it
dethrones Sony's PlayStation. Enter the Xbox 360.

360 Spec
The Xbox 360, like all video game consoles, is
just a computer with hardware and software
dedicated to the function of running video game
software. The original Xbox was in essence a
Windows PC with a modified Pentium III processor,
some relatively powerful graphics and audio
hardware and a modified version of the Microsoft
operating system Windows 2000, all packaged in
that distinctive black box. The Xbox 360 is
also a specially packaged computer, but once you
look inside, you realize that this console has
quite a bit under the hood. We'll start by
looking at the standard spec list released by
Microsoft.

The Heart of the 360
Like any computer, the CPU is the heart of the
Xbox 360. Microsoft has outfitted the 360 with a
165-million transistor, multi-core processor
running three 3.2-GHz PowerPC cores. A core is
another name for a processor. Recently, hardware
manufacturers have started combining several
cores, or processors, onto one chip. This is a
multi-core processor. Multi-core processors offer
a combination of tremendous computing
capabilities and efficient power consumption.
They split heavy work loads over multiple
powerful processors rather than giving all the
work to one super-powerful processor.
36
The other interesting thing to note about the
Xbox 360 CPU is that each core is capable of
processing two threads simultaneously. Think of a
thread as a set of instructions for a program's
job. The core processes these instructions and
does the heavy lifting to get the job done. A
conventional processor is traditionally capable
of running a single execution thread. Because the
Xbox 360 cores can each handle two threads at a
time, the 360 CPU is the equivalent of having six
conventional processors in one machine. What
this means when you are playing video games is
that the Xbox 360 can dedicate one core entirely
to producing sound, while another may split
running the game's collision and physics engine.
The system may allocate an entire processor just
to rendering hi-def graphics. It's really up to
the game developers how the system's considerable
resources are used. With a multi-core processor,
the system is powerful enough to pull off the
computational demands needed for an amazing
gaming experience without even breaking a sweat.
