Before continuing, we should warn you:
-- The overclocked card we have is not the one provided by Apple, but another PC-flashed card. It has a newer, more efficient heatpipe than Apple's card.
-- Though the overclock that we have achieved yesterday was relatively simple and rather dangerous, the technique we are proposing today would certainly not be supported by all cards.
This time, we have decided to go much further, and after verifying that the card was supported under Windows, we have pushed the GPU to 721 MHz, the ROPS to 1802 MHz and RAM to 2042 (2x1021) MHz.
Here are the results obtained under GLview:
Center: results of yesterday's trial (roughly 7% performance gain)
Bottom: results of today's trial (10 to 14% performance gain over the base model)
In the future, we will change the heatpipe and try to modify the memory and GPU settings to go even further. The aim will be to go to the extreme limits of the architecture of this product.
But already, with these frequencies, (if we trust the specifications given by Apple) this card has more power and memory bandwidth than the Quadro FX 5600... But Apple's figures for the 8800 GT are obviously wrong.
