• 514 million 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 10.1, including new Shader Model 4.1, geometry generation, and stream output
• 128-bit memory bus: two 64-bit controllers supporting DDR2/DDR3/GDDR2/GDDR3 memory
• Core clock: 600-750 MHz
• 8 SIMD cores, including 320 scalar floating-point ALUs (integer and floating-point formats, support for FP32 and FP64 in compliance with IEEE 754)
• 8 enlarged texture units supporting FP16 and FP32 formats
