Xbox technical specifications
The Xbox technical specifications describe the various components of the Xbox video game console.
Central processing unit
Memory
- Shared graphics memory sub-system
- 64
- 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 Samsungdepending on manufacture date and location
- 64
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.
- Floating-point performance: 4.66 GFLOPS[6]
- Geometry engine: 115 million vertices per second, 125 million particles per second (peak)
- 4 pixel pipelines with 2 texture unitseach
- Peak fillrate:
- Rendering fillrate: 932 megapixels per second (233 MHz × 4 pipelines)
- Texture fillrate: 1,864 megatexels per second (932 MP × 2 texture units)
- Realistic fillrate:
- Rendering fillrate: 250–700 megapixels per second, with alpha blending and texture mapping[7]
- Texture fillrate: 500–1400 megatexels per second (250-700 MP × 2 texture units)
- Rendering fillrate: 250–700 megapixels per second, with
- Peak triangle performance: 29,125,000 32-pixel triangles per second, raw or with 2 textures and lighting (32-pixel divided from peak fillrate)
- 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 (32-pixel divided from realistic fillrate)
- 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 (NV Quincunx, supersampling, multisampling)
- 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 (233 MHz) thus slower than Geforce 4 series starting at 250 MHz.[8]
- Floating-point performance: 4.66
Storage
- Storage media
- 2×–5× (2.6 MB/s–6.6 MB/s) CAV DVD-ROM
- 8 or 10 FATX file system
- Optional 32 MB memory card for saved game file transfer
Audio
- Audio processor: NVIDIA "MCPX" (a.k.a. SoundStorm "NVAPU")
Connectivity
- Controller ports: 4 proprietary USB1.1 ports
- A/V outputs: composite video, S-Video, component video, HDMI (via 3rd party), 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/Physical Layer Transceiver
- DVD movie playback (add-on required)
