nVidia annoncerer GeForce Go 6800 Ultra

nVidia har annonceret en ny topmodel blandt grafikprocessorer til bærbare computere, GeForce Go 6800 Ultra. Chippen er clocket til 450 MHz, mens hukommelsen kører 700 MHz hvis man bruger DDR, eller 1100 MHz, hvis man benytter GDDR3.

Den langsommere GeForce Go 6800 vil højst sandsynligt køre med lidt lavere clockfrekvens. Hukommelseshastigheden vil være sat ned til 300 MHz, hvis man benytter DDR, eller 600 MHz med GDDR3.

GeForce Go 6800 Ultra er mest rettet mod de store bærbare computere, og de såkaldte Desktop Replacements, og begge grafikprocessorer er udelukkende rettet mod entusiaster, der vil have det bedste.

Ifølge nVidia skulle en bærbar computer med GeForce Go 6800 Ultra kunne nå 5000 3Dmarks i 3DMark05 eller 12000 3Dmarks i 3DMark03, det er det dobbelte af ATi's Mobility Radeon 9800 PRO.

According to Nvidia, the Ultra version of the Go 6800 has a memory bandwidth of 35.2 Gbit per second and posts a fill rate of 5.4 billion pixels per second. The processor core is clocked with 450 MHz, the memory data rate is 700 MHz for DDR1 and DDR2, GDDR3 runs at 1100 MHz.

The chips presentation platform, Dell's Inspiron XPS Gen2 notebook, will reach new performance records across the benchmark board, Nvidia claims. Compared to the direct predecessor, an XPS system equipped with an ATI Mobility Radeon 9800 chip, the new notebook will at least double graphics performance topping 5000 points in 3DMark05 and 12,000 points in 3DMark03, Nvidia said. The 17-inch display of the device enables a resolution of 1920 x 1200 pixel (WUXGA), harddrive sizes range from 60 to 100 GByte.
