Xbox technical specifications

Central processing unit

• CPU: 32-bit 733 MHz, custom Intel Pentium III Coppermine-based processor in a Micro-PGA2 package. 180 nm process.
• *133 MHz 64-bit GTL+ front-side bus to GPU
• *32KB L1 cache. 128 KB on-die L2 cache
• *Streaming [SIMD Extensions|SSE] floating point SIMD. Four single-precision floating point numbers per clock cycle.
• *MMX integer SIMD

Memory

• Shared graphics memory sub-system
• *64 MB DDR SDRAM at 200 MHz; in dual-channel 128-bit configuration giving 6400 MB/s
• **Maximum of 1.06 GB/s bandwidth accessible by CPU FSB
• **Theoretical 5.34 GB/s bandwidth shared by rest of the system
• *Supplied by Hynix or Samsung depending on manufacture date and location

Graphics processing unit

• GPU and system chipset: 233 MHz "NV2A" ASIC. Co-developed by Microsoft and Nvidia and essentially a variant of Geforce 3 chips.
• *Geometry engine: 115 million vertices per second, 125 million particles per second
• *4 pixel pipelines with 2 texture units each
• *Peak fillrate:
• **Rendering fillrate: 932 megapixels per second
• **Texture fillrate: 1,864 megatexels per second
• *Realistic fillrate:
• **Rendering fillrate: 250–700 megapixels per second, with Z-buffering, fogging, alpha blending and texture mapping
• **Texture fillrate: 500–1400 megatexels per second
• *Peak triangle performance: 29,125,000 32-pixel triangles per second, raw or with 2 textures and lighting
• **485,416 triangles per frame at 60 frames per second
• **970,833 triangles per frame at 30 frames per second
• *Realistic triangle performance: 7,812,500–21,875,000 32-pixel triangles per second, with 2 textures, lighting, Z-buffering, fogging and alpha blending
• **130,208–364,583 triangles per frame at 60 frames per second
• **260,416–729,166 triangles per frame at 30 frames per second
• *4 textures per pass, texture compression, full scene anti-aliasing
• *Bilinear, trilinear, and anisotropic texture filtering
• *Performance lies between a Geforce 3 Series GPU and a Geforce 4 Series GPU. This is due to the added vertex shader present on the ASIC, thus doubling the vertex output compared to Geforce 3 ASICs. Clock speed is the same as the original Geforce 3 series GPU thus slower than Geforce 4 series starting at 250MHz.

Storage

• Storage media
• *2×–5× CAV DVD-ROM
• *8 or 10 GB, 3.5 in, 5,400 RPM hard disk formatted to 8 GB with FATX file system
• *Optional 8 MB memory card for saved game file transfer

Audio

• Audio processor: NVIDIA "MCPX"
• *Wolfson Microelectronics XWM9709 AC97 Revision 2.1 Audio Codec
• *Integrated Parthus DSP for realtime Dolby Digital encoding
• *64 3D sound channels
• *HRTF Sensaura 3D enhancement
• *MIDI DLS2 Support
• *Monaural, Stereo, Dolby Surround, Dolby Digital Live 5.1, and DTS Surround audio output options

Connectivity

• Controller ports: 4 proprietary USB 1.1 ports
• A/V outputs: composite video, S-Video, component video, HDMI, SCART, Digital Optical TOSLINK, and stereo RCA analog audio
• *S-Video requires "Advanced AV Pack", component video requires "High Definition AV Pack", TOSLINK requires either of the two
• Resolutions: 480i, 480p, 576i, 576p, 720p, 1080i
• Integrated 10/100BASE-TX wired Ethernet with ICS ICS1893AF Physical Layer Transceiver
• DVD movie playback

Physical specifications
