A Closer Look

NVIDIA's cooler uses a complex heatsink base with vapor-chamber technology to cool the GPU, memory chips, and secondary components. A backplate is not included.


In order to measure real-time power consumption of the card, NVIDIA has placed a single Texas Instruments INA 3221 power sensor on their card. This chip replaces the three INA219 sensors that were used on earlier cards, providing space and cutting on cost.


The card requires one 6-pin and one 8-pin PCI-Express power cable for operation. This power configuration is good for up to 300 W of power draw.


NVIDIA uses an OnSemi NCP4206 voltage controller on the Titan. We have seen this controller on many designs before. It is a cost effective solution that does not provide any I2C, so advanced monitoring is not possible. Please note how it sits on its own PCB, which means we could see different voltage controllers in the future. The GTX 680 uses a similar approach, but the variety of voltage controllers was relatively low.


The GDDR5 memory chips are made by Samsung and carry the model number K4G20325FD-FC03. They are specified to run at 1500 MHz (6000 MHz GDDR5 effective).


NVIDIA's GK110 graphics processor was first introduced as a Tesla-only product to power demanding GPU compute applications. NVIDIA has now released it as a GeForce GPU too. It uses 7.1 billion transistors on a die size that we measured to be 561 mm². The GPU is produced on a 28 nanometer process at TSMC, Taiwan.
