In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660 Ti 3-way SLI are significantly better than the Nvidia GeForce GTX 670 PNY 2GB Edition.

The GTX 660 Ti and the GTX 670 have the same core clock speed of 915 MHz, but the GTX 660 Ti has 224 more Texture Mapping Units than the GTX 670. As a result, the GTX 660 Ti exhibits a 204.9 GTexel/s better Texture Fill Rate than the GTX 670. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 660 Ti and the GTX 670 have the same core clock speed of 915 MHz, but the GTX 660 Ti has 40 more Render Output Units than the GTX 670. As a result, the GTX 660 Ti exhibits a 36.6 GPixel/s better Pixel Fill Rate than the GTX 670. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 660 Ti was released less than a year after the GTX 670, and so they are likely to have similar driver support for optimizing performance when running the latest games.

Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.

The GTX 660 Ti has 4096 MB more video memory than the GTX 670, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 660 Ti also has superior memory performance overall.

The GTX 660 Ti has 240.3 GB/sec greater memory bandwidth than the GTX 670, which means that the memory performance of the GTX 660 Ti is massively better than the GTX 670.

The GeForce GTX 660 Ti 3-way SLI has 4032 Shader Processing Units and the GeForce GTX 670 PNY 2GB Edition has 1344. However, the actual shader performance of the GTX 660 Ti is 3951 and the actual shader performance of the GTX 670 is 1317. The GTX 660 Ti having 2634 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 660 Ti delivers a massively smoother and more efficient experience when processing graphical data than the GTX 670.

The GeForce GTX 660 Ti 3-way SLI requires 450 Watts to run and the GeForce GTX 670 PNY 2GB Edition requires 170 Watts. We would recommend a PSU with at least 500 Watts for the GTX 670, but we do not have a recommended PSU wattage for the GTX 660 Ti. The GTX 660 Ti requires 280 Watts more than the GTX 670 to run. The difference is significant enough that the GTX 660 Ti may have an adverse affect on your yearly electricity bills in comparison to the GTX 670.

GPU Mini Review

Mini ReviewGeForce GTX 660 Ti 3-way SLI is a solution of three GeForce GTX 660 Ti put together using NVIDIA'S SLI technology.
Check the page of GeForce GTX 660 Ti to know more about its chip.
As usual, SLI relies a lot on proper driver support and may suffer from micro-stuttering in lower frame rates (below 30). Benchmarks indicate the performance is overall, is up to X% better than a single GeForce GTX 660 Ti performing by itself but at times (depending whether or not the 3D game supports SLI or in the graphics driver) it performed worse than a single GeForce GTX 660 Ti. Expect this combination to draw up to 450 Watt though the average power consumption should be slightly lower.
Even the most demanding games will run at the highest settings.
GeForce GTX 670 PNY 2GB Edition is a renamed GeForce GTX 670 with no new features - not even a new cooling system. Its performance is exactly like the reference card.
