A Closer Look

The back of the card is covered by two heatspreaders that cool the memory chips. They also serve as protection against damage to the components on the back of the card.


NVIDIA's thermal solution uses two vapor chamber baseplates and a central fan that exhausts hot air out of the computer case.


The card requires two 8-pin PCI-Express power connectors. Together with the PCI-Express x16 slot this configuration is good for 375 W of power.


The "GeForce" logo you see below the power connectors is backlit by a white LED which adds a very nice touch to the running card.


The GDDR5 memory chips are made by Samsung, and carry the model number K4G10325FE-HC04. They are specified to run at 1250 MHz (5000 MHz GDDR5 effective).


NVIDIA is using two CHiL CHL8266 voltage regulators on their card, one for each GPU. This is the same voltage regulator design as on the GTX 570 and GTX 580.


The PCI-Express bridge chip which connects the two GPUs and interfaces with the system via PCI-Express 2.0 is NVIDIA's NF200. It has been seen on numerous graphics cards and motherboards.


NVIDIA's GF110 graphics processor is made on a 40 nm process at TSMC Taiwan. The silvery surface you see is the GPU heatspreader, the actual die sits under that.
