In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660 Ti Twin Frozr 3GB Edition are marginally better than the Nvidia GeForce GTX 660 Ti.

The GTX 660 Ti has a 52 MHz higher core clock speed and the same number of Texture Mapping Units as the GTX 660 Ti. This results in the GTX 660 Ti providing 5.8 GTexel/s better texturing performance. 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 has a 52 MHz higher core clock speed than the GTX 660 Ti and the same number of Render Output Units. This results in the GTX 660 Ti providing 1.2 GPixel/s better pixeling performance. 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 660 Ti, 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 1024 MB more video memory than the GTX 660 Ti, 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 memory bandwidth of the GeForce GTX 660 Ti Twin Frozr 3GB Edition and the GeForce GTX 660 Ti are the same, which means the GTX 660 Ti and the GTX 660 Ti have equal limitations when it comes to graphical data transfer.

Both the GeForce GTX 660 Ti Twin Frozr 3GB Edition and the GeForce GTX 660 Ti have 1344 Shader Processing Units. Having the same number of SPUs and using the same architecture means that the performance they offer can be compared by looking at the memory bandwidth, Texture and Pixel Rates. In this case, the GTX 660 Ti has 5.8 GTexel/s better Texture Fill Rate and 1.2 GPixel/s better Pixel Fill Rate, but the has GB/sec greater memory bandwidth. Although the GPUs are very similar in performance, the GTX 660 Ti takes the edge.

The GeForce GTX 660 Ti Twin Frozr 3GB Edition requires 150 Watts to run and the GeForce GTX 660 Ti requires 150 Watts. We would recommend a PSU with at least 450 Watts for the GTX 660 Ti and a PSU with at least 450 Watts for the GTX 660 Ti. The two GPUs require the same amount of wattage to run. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.

GPU Mini Review

Mini ReviewGeForce GTX 660 Ti Twin Frozr 3GB Edition is a special edition of GeForce GTX 660 Ti.
The new features include the Twin Frozr III Thermal Design which is 25ºC cooler and 16.9 dB quieter than reference design, according to MSI. In terms of overclocking, the base-clock was increased from 915MHz to 967MHz and the boost clock can now reach 1046MHz, instead of 980MHz. The memory clock was left untouched but the frame buffer was increased to 3GB which actually reduces the performance due to the 192-bit bus width not being to handle the 3GB efficiently.
The overclocking is somewhat relevant and benchmarks indicate the performance boost is around 1% when compared to standard GeForce GTX 660 Ti.
GeForce GTX 660 Ti is a Performance Graphics Card based on the Kepler Architecture.

The Kepler Architecture was NVIDIA's big step to power efficiency. Each Stream Multiprocessor (SMX) now hosts 192 Shader Processing Units - against the 48 of older Fermi Architecture, and has been redesigned being now clocked at the same speed of the Central Unit. This means they are more energy efficient and will consequently lead to cooler operating temperatures. However, it also means they are weaker. It can be said that one Fermi SMX is as fast as 2 Kepler SMXs.
Additionally, and not available in all GPUs, Kepler also introduced the Boost Clock Feature. The Boost Clock is an even higher Clock Speed activated when in gaming mode and becomes the effective speed of the GPU. GPU
It equips a GPU GK104-300-KD-A2 which has 7 Stream Multiprocessors activated and thus offers 1344 Shader Processing Units, 112 TMUs and 24 ROPs. The Central Unit is initially clocked at 915MHz and goes up to 980MHz, in Turbo Mode.

The GPU accesses a 2GB frame buffer of fast GDDR5, through a 192-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 1502MHz.

Power Consumption
With a rated board TDP of 150W, it requires at least a 450W PSU with two available 6-pin connectors.

At 1920x1080, the best suited resolution for GeForce GTX 660 Ti, benchmarks indicate its performance is a little over the older GeForce GTX 580.

System Suggestions
GeForce GTX 660 Ti is best suited for resolutions up to and including 1920x1080. We recommend a Strong Processor and 8GB of RAM for Optimal Performance.
