GT200, GeForce GTX 200 series

GT200 specifications

• Codename: GT200
• Process technology: 65nm
• 1.4 billion transistors
• Unified architecture with an array of common processors for streaming processing of vertices and pixels, as well as other data
• Hardware support for DirectX 10, including Shader Model 4.0, geometry generation, and stream output
• 512-bit memory bus, eight independent 64-bit controllers
• Core clock: 602 MHz (GeForce GTX 280)
• ALUs operate at more than a doubled frequency (1.296 GHz for GeForceGTX 280)
• 240 scalar floating-point ALUs (integer and floating-point formats, support for FP32 and FP64 according to IEEE 754(R), two MAD+MUL per cycle -- read the details below)
• 80 texture address and filtering units (as in G84/G86 and G92), support for FP16 and FP32 components in textures
• Dynamic branching in pixel and vertex shaders
• 8 wide ROPs (32 pixels) supporting antialiasing with up to 16 samples per pixel, including FP16 or FP32 frame buffer. Each unit consists of an array of flexibly configurable ALUs and is responsible for Z generation and comparison, MSAA, blending. Peak performance of the entire subsystem is up to 128 MSAA samples (+ 128 Z) per cycle, in Z only mode - 256 samples per cycle
• Multiple render targets (up to 8 buffers)
• All interfaces (2 x RAMDAC, 2 x Dual DVI, HDMI, DisplayPort, HDTV) are integrated into a separate chip.
