NVIDIA ha ufficialmente annunciato il nuovo chip grafico NV40, che sarÓ montato sulle schede video GeForce 6800 e GeForce 6800 Ultra.

Il GeForce 6800 e GeForce 6800 Ultra saranno identici come architettura, l'unica differenza sarÓ la presenza di 16 pipeline di rendering nella versione Ultra, contro le 12 della versione "normale". Inoltre il GeForce 6800 Ultra monterÓ 256MB di memoria GDD3, mentre il GeForce 6800 solo 128 MB.
Ecco le specifiche: - 16-pipeline superscalar architecture with 6 vertex modules, DDR3 support and real 32-bit pipelines - PCI Express x16, AGP 8x support - 222 million transistors - 400MHz core clock - Chips made by IBM iwth 0.13Ám process - 40x40mm FCBGA (flip-chip ball grid array) package - Driver ForceWare 60+ series - Supports 256-bit GDDR3 with over 550MHz (1.1GHz DDR) clock rates - NVIDIA CineFX 3.0 supporting Pixel Shader 3.0, Vertex Shader 3.0; real-time Displacement Mapping and Tone Mapping; up to 16 textures/pass, 16-bit and 32-bit FP formats, sRGB textures, DirectX and S3TC compression; 32bpp, 64bpp and 128bpp rendering; lots of new visual effects - NVIDIA HPDR (High-Precision Dynamic-Range) on OpenEXR technology supporting FP filtering, texturing, blending and AA - Intellisample 3.0 for extended 16xAA, improved compression performance; HCT (High-resolution compression), new lossless compression algorithms for colors, textures and Z buffer in all modes, including hi-res high-frequency, fast Z buffer clear - NVIDIA UltraShadow II for 4 times the performance in highly shadowed games (e.g. Doom III) comparing to older GPUs - Extended temperature monitoring and management features - Extended display and video output features, including int. videoprocessor, hardware MPEG decoder, WMV9 accelerator, adaptive deinterlacing, video signal scaling and filtering, int.
