Theoretische Benchmarks zum G70-Chip

Theoretische Benchmarks (Forts.)

Als nächstes steht der Archmark in der Version 0.50 auf dem Programm. Jenes Tool misst verschiedene Füllraten, aber auch Sachen wie die verfügbare Bandbreite, Texturingleistung und einiges anderes mehr.

Diese vielen Werte werden wahrscheinlich nur denjenigen etwas sagen, die sich schon eingehend mit dem ArchMark beschäftigt haben ;). Auffällig ist eventuell, daß die simulierte GeForce 6800 Ultra auf G70-Basis teilweise die absolut identischen Werte wie eine GeForce 7800 GT erbringt, obwohl es hier sowohl Pipeline- wie auch Takt-Unterschiede gibt. Dies deutet eventuell darauf hin, daß nVidia bei der GeForce 7800 GT noch etwas mehr deaktiviert hat als nur die 4 Pixel- und 1 Vertex-Pipelines, womit diese 20-Pipelines-Karte trotz höherer Pipeline-Anzahl teilweise nicht mehr Rohpower hat als die auf 16 Pipelines limitierte GeForce 7800 GTX (simulierte GeForce 6800 Ultra).
