XFX 8800 GTS 512 and Asus 8800 GT 512 - G92 shoot out
Overclocking was performed using Nvidia's drivers and the nTune plugin. No hard or soft mods were performed on the cards and overclocking in this way is meant to represent an "easy overclock", giving value for money on each card without making too much effort.
Here's what happened:
Oddly enough, the cards were almost the opposite of each other. Whilst the XFX 8800 GTS 512 XXX Alpha Dog Edition made some great ground up on stock core clock, the Asus 8800 GT Top had a nice memory overclock.
Let's see how this affects performance:
The chart above shows us that the large core overclock on the 8800 GTS was more effective than the large memory overclock on the 8800 GT.
Still, what we have to remember is that both of these GPU's are overclocked out of the box and so any overclocking above that is even more of a bonus than normal.
For a good approximation of the power consumption of each card, I measured the power consumption of the total system for each card at the wall socket.
Idle measurements were taken over a 30 minute period sitting on the desktop of Windows Vista and load measurements were taken again over a 30 minute period whilst stressing each card using RTHDRIBL
in full screen mode 1920 x 1200.
As you can see, the power consumption of the XFX 8800 GTS and the Asus 8800 GT was very similar at idle, but at load the 8800 GTS pushed up towards 8800 GTX numbers. Still, the beastly 8800 GTX managed to stay a fair way ahead in the energy guzzling stakes.
