Detailed specifications

• CPU: Micro PGA2 733 MHz Intel Coppermine Core. Basically a Pentium III.
  • Intel IA-32 instruction set
  • SIMD: SSE. Four single-precision floating-point numbers in one instruction.
    • Theoretical maximum 4 FLOPS/cycle (2.9 gigaFLOPS for Xbox)
    • Pentium III had architectural drawbacks that lessened real-world SSE throughput.
  • SIMD: MMX. Integer functions. Switching between FPU and MMX is slow, so not of great use for 3D rendering tasks. Often used for audio and video.
  • 133 MHz FSB. Same as fastest Pentium III EB CPUs.
  • 32 kB L1 cache. 128 kB L2 Advanced Transfer Cache (256-bit). Same size as Celeron, but 8-way associative like Pentium III E.
• Unified Memory Subsystem: Total (shared) Memory: 64 MB DDR SDRAM running at 200 MHz, supplied by Hynix or Samsung depending on manufacture date and location
  • Theoretical Memory Bandwidth: 6.4 GB/s
• Graphics Processor: 233 MHz custom chip "NV2A", developed by Microsoft and nVIDIA (fits between GeForce 3 and GeForce 4 in capability). Enhanced vertex processing with 2 vertex shaders, and more flexible pixel shading than DirectX 8.
  • Theoretical Geometry Rate: 115+ million vertices/second
  • Theoretical Particle Performance: 125 M/s
  • Pipeline Configuration: 4 pixel pipelines with 2 texture units each
  • Theoretical Pixel Fill Rate: 932 Megapixels/second (233 MHz x 4 pipelines)
  • Theoretical Texture Fill Rate: 1,864 Megatexels/second (932 MP x 2 texture units)
  • Simultaneous Textures: 4
  • Compressed Textures: Yes (6:1 through DDS)
  • Full Scene Anti-Aliasing: Yes
• Storage Medium: 2-5x DVD (XFAT), 8 gigabyte hard disk (new consoles contain a 10GB physical hard drive, though it is formatted to only use 8GB, uses XFAT), optional 8MB memory card for savegame transfer
• Audio Processor : nVIDIA MCPX (a.k.a. Soundstorm NVAPU)
  • Audio Channels: 64 3D channels (up to 256 stereo voices)
  • 3D Audio Support: HRTF Sensaura 3D enhancement.
  • MIDIDLS2 Support: Yes
  • AC3 (Dolby Digital)Encoded Game Audio: Yes (via TOSLINK)
• BroadbandEnabled: Yes (10/100base-T ethernet)
• DVD Movie Playback: Yes (separate DVD Playback Kit/Remote required or by modding the Xbox and running DVD-playing homebrew software)
• Maximum Resolution (2x32bpp frame buffers +Z): 1920(vert.)x1080(horiz)
  • Note: NTSC (Non-HD) TV's have less than 500 horizontal lines. PAL TV's have less than 600 horizontal lines.
• EDTVand HDTV Support: 480p/720p/1080i (see game boxes for supported resolutions).
• Controller Ports: 4 proprietary USB ports
• Weight: 3.86 kg
• Dimensions: 320 × 100 × 260 mm (12.5 × 4 × 10.5 inches)
