Custom IBM PowerPC-based CPU - designed by IBM based on their Power
Architecture
- Specs:
- Three symmetrical cores, each running at 3.2 GHz
- Two hardware threads per core for a total of six hardware threads
- VMX-128 vector unit per core; three total
- 1 MB L2 cache
- Reduced Instruction Set Computing (RISC)-based architecture
- Performance:
- 9 billion dot product operations per second
- 1 teraflop of system-level, floating-point performance
Memory
- Specs:
- 512 MB of GDDR3 RAM
- 700 MHz DDR
- Unified memory architecture
- Bandwidth performance:
- 22.4 GB/s memory interface bus bandwidth
- 256 GB/s memory bandwidth to EDRAM
- 21.6 GB/s front-side bus
GPU specs (graphics)
Custom ATI graphics processor
- Specs:
- 500MHz processor
- 10 MB of embedded DRAM
- 48-way parallel floating-point dynamically scheduled shader pipelines
- Unified shader array
- Performance:
- Polygon performance = 500 million triangles per second
- Pixel fill rate = 16 gigasamples per second using 4x MSAA
- Shader performance = 48 billion shader operations per second
- All games supported at 16:9, 720p, and 1080i, anti-aliasing
- Notes:
- Unified shader architecture - provides 48 parallel shaders capable of operating on data for both pixels and vertices
- Automatically allocates shader resources to optimize address a computational limitation, vertex- or pixel-related
- Dramatically reduces parasitic resistance and capacitance throughout the memory array, thus minimizing both random access time and power consumption
- Can manage and maintain state information on 64 separate threads in hardware
- Can switch between threads without any delay in order to keep the shader arrays occupied at all times
- Also functions as the main memory controller
Audio
- Multi-channel surround sound output
- Supports 48KHz 16-bit audio
- 320 independent decompression channels
- 32-bit audio processing
- Over 256 audio channels
Storage
- Specs:
- Detachable and upgradeable 20GB hard drive
- Support for 2 Memory Units (MU) starting at 64 MB
- Digital media support:
- Support for DVD-Video, DVD-ROM, DVD-R/RW, DVD+R/RW, CD-DA, CD-ROM, CD-R, CD-RW, WMA CD, MP3 CD, JPEG Photo CD
- Ability to stream media from portable music devices, digital cameras and Windows XP-based PCs
- Ability to rip music to the Xbox 360 hard drive
- Custom playlists in every game
- Built-in Media Center Extender for Windows XP Media Center Edition 2005
I/O
- Support for up to four wireless game controllers
- Three USB 2.0 ports
- Standard-definition and high-definition video output supported
Internet connectivity
- Built-in Ethernet port
- Wi-Fi ready: 802.11a, 802.11b, and 802.11g
- Video camera ready
- Out-of-the-box access to Xbox Live
- Voice chat ready
System orientation
- Stands vertically or horizontally
