GeForce GTX 660 

The 25% narrower memory-bus width shouldn't worry you because NVIDIA uses 6.00 GHz memory clock speed, resulting in a memory bandwidth of 144.

It provides cooling for memory chips and voltage regulation circuitry.

It's interesting to note that, if the block diagram is anything to go by, NVIDIA created a GPC with just one SMX unit.

The chip may really have six SMX units, but it's kept out of the block diagram to, perhaps, help harvest the chip better.

Here, the MSI card delivers the highest overclocked performance despite reaching lower clock speeds.

Unfortunately, memory has remained at the default speed of 1500 MHz.
