We are eagerly awaiting Nvidia Geforce GTX 660 Ti and benchmarks are starting to circulate. The card in question comes from MSI and besides getting tuned frequencies, it will also get more memory than what is expected from the reference model from Nvidia.
MSI’s coming Geforce GTX 660 Ti Hawk has been pictured in 3-way SLI and at a closer look it looks a lot like GTX 670 Power Edition with Twin Frozr IV cooling. This matches previous sources that have stated it will use the GK104 GPU, which means the majority of GTX 660 Ti cards will use the same circuit board and cooler as GTX 670.

There are not benchmarks with 3-way SLI available, but we will have to settle for results with a single MSI GTX 660 Ti Hawk. In 3DMark 11 the card scored X2862 on the Extreme settings, about the same as GTX 670. The difference between the cards lies in the memory bus, but MSI has compensated for that through factory overclocking.

The launch of Geforce GTX 660 Ti is slated for August and it is still unsure what the price will be. If rumors are true it will cost 50-100€ less than GTX 670.

3DMark11 doesn’t stress ROP or memory bandwidth. This card may do very well in this synthetic benchmark but I doubt it can make up for lack of memory bandwidth and pixel fill-rate against the 670 in real world games with AA/AF enabled without overclocking the core to 1200mhz.
