A Closer Look

The cooler of the GTX 275 is identical to that on the GTX 285 or 55 nm GTX 260.


Two six pin power connectors are present on the card. Both are required for operation of the card. Further to the right in the picture you can see the white input for SPDIF audio.


The GDDR3 memory chips are made by Samsung and carry the model number K4J52324QH-Hj08. With a cycle time of 0.8 ns, they are specified to run at 1250 MHz.


The ADP4100 voltage controller has been spotted first on the NVIDIA P897 design for the GTX 260. It does not support the I2C interface which means software voltage control will be almost impossible to implement.


The GPU is the NVIDIA GT200b, which is made in a 55 nm process with 1.4 billion transistors.
