This is going to be a breakdown of the raw power of the xbox 360.

Here are the specs of the system:

Custom IBM PowerPC-based CPU
• Three symmetrical cores running at 3.2 GHz each
• Two hardware threads per core; six hardware threads total
• VMX-128 vector unit per core; three total
• 128 VMX-128 registers per hardware thread
• 1 MB L2 cache

CPU Game Math Performance
• 9 billion dot product operations per second

Custom ATI Graphics Processor
• 500MHz processor
• 10 MB of embedded DRAM
• 48-way parallel floating-point dynamically scheduled shader pipelines
• Unified shader architecture

Polygon Performance
• 500 million triangles per second

Pixel Fill Rate
• 16 gigasamples per second fill rate using 4x MSAA

Shader Performance
• 48 billion shader operations per second

Memory
• 512 MB of GDDR3 RAM
• 700 MHz of DDR
• Unified memory architecture

Memory Bandwidth • 22.4 GB/s memory interface bus bandwidth
• 256 GB/s memory bandwidth to EDRAM
• 21.6 GB/s front-side bus

Overall System Floating-Point Performance
• 1 teraflop

Storage
• Detachable and upgradeable 20GB hard drive
• 12x dual-layer DVD-ROM
• Memory Unit support starting at 64 MB

These specs look pretty daunting but what is really important is the three identical processors running at a blistering 3.2 Ghz and the custom ATI graphics processor running at 500 Mhz, which applys full screen antialiasing to the games which make them very smooth and sharp. This awesome hardware along with the 360's ability to run in 1080i/p high definition resolutions makes it an amazing system, as well as an astonishing bargain.
