Nvidia GeForce GTX 660 Ti Review (Part 1/3) – Gigabyte’s Windforce OC Edition

When we pop off the cooler, we can see that the GTX 660Ti shares many similarities to the GTX 670's compact PCB that we saw a few months ago.

Here we have the business end of things – a Kepler GK104 die flanked by eight Hynix GDDR5 memory chips (two behind) clocked at 1.5GHz.

 

A dumb ON semiconductor NCP5392P buck controller manages 4-phase of power, with ferrite cores and solid capacitors ensuring reliable continous operation.

 

The heatsink block itself uses HDT (heatpipe direct touch) to conduct heat away from the GPU core, and there are also sticky thermal tape for the MOSFETs and BGA memory modules. Twin 92mm fans provide a lot of airflow for heat dissipation.
