Today we will be examining the eVGA GeForce GTX 285 SSC. As can be gleamed from the name, this card is built using the NVIDIA GeForce GTX 285 chip. Video cards based upon this GPU have been on the market for a while, and have had this graphics card power my system for the past few months.
eVGA GeForce 285 GTX SSC Edition
As one would expect by the name, this GPU is an evolution of the GeForce 280 GTX chip. Most of the evolutionary benefits can be attributed to die shrink to 55nm from 65nm. Benefitting from this, the 285 GTX provides an additional 40MHz for the core clock speed, an additional 180 MHz for the stream processors and an extra 270MHz on the memory.
Note that we are examining the factory-overclocked SSC edition from eVGA. The SSC edition adds an extra oomph. The core clock is running at 702MHz, 54MHz over the standard 285 GTX and a full 100MHz faster than the 280 GTX. The shader clock is running at 1584MHz, 108MHz above standard and the memory is running at 2646MHz, 162MHz above the typical 285 GTX.
While some things change, the basic infrastructure of the card remains the same as it still uses 240 stream processors divided into 10 clusters, 80 texture units, 32 ROPs and 1024 MB of GDDR3, which is benefitting from a full 512 bit interface bus.
The 285 GTX is not only faster than the 280 GTX, it is also more power efficient. NVIDIA has been able to reducing the amount of power needed to not only power the card, down to 183W from 236W on the 280 GTX, but has cut the power flowing into the card as the 285 GTX no longer necessitates an eight and six pin PCI-Express power connector, but now only requires two six pin connectors. This is the same connectivity requirements as the 260 GTX and 275 GTX.
NVIDIA's current flagship product, the GeForce 295 GTX, is a multi-GPU solution; therefore the 285 GTX is currently NVIDIA's fastest single GPU solution.
