One of the most anticipated graphics card releases of the year occurred this month in the form of the GeForce GTX 660 Ti from NVIDIA, and as you would expect we were there on the day one with an in-depth review of the card at reference speeds.

The GeForce GTX 660 Ti is based on GK104, and what you might find interesting is that it is nearly identical to the specifications of the GTX 670. Both utilize 7 SMX units for a total of 1344 stream processors – or CUDA cores – and both run at a reference clock speed of 915 MHz base and 980 MHz Boost. Both include 112 texture units though the GeForce GTX 660 Ti does see a drop in ROP count from 32 to 24. Also, L2 cache drops from 512KB to 384KB along with a memory bus width drop from 256-bit to 192-bit.

We already spent quite a lot of time talking about the GTX 660 Ti compared to the other NVIDIA and AMD GPUs in the market in our review (linked above) as well as on our most recent episode of the PC Perspective Podcast. Today's story is all about the retail cards we received from various vendors including EVGA, Galaxy, MSI and Zotac. We are going to show you each card's design, the higher clocked settings that were implemented, performance differences between them and finally the overclocking comparisons of all four.
