In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 1060 Gigabyte GTX G1 Gaming 6GB are noticeably better than the Nvidia GeForce GTX 660 Ti SLI.

The GTX 1060 has a 679 MHz higher core clock speed than the GTX 660 Ti, but the GTX 660 Ti has 144 more Texture Mapping Units than the GTX 1060. As a result, the GTX 660 Ti exhibits a 77.5 GTexel/s better Texture Fill Rate than the GTX 1060. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 1060 has a 679 MHz higher core clock speed than the GTX 660 Ti and the same number of Render Output Units. This results in the GTX 1060 providing 32.6 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 1060 was released over three years more recently than the GTX 660 Ti, and so the GTX 1060 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GTX 660 Ti 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 1060 has 2048 MB more video memory than the GTX 660 Ti, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The GTX 660 Ti has 96.2 GB/sec greater memory bandwidth than the GTX 1060, which means that the memory performance of the GTX 660 Ti is massively better than the GTX 1060.

The GeForce GTX 660 Ti SLI has 2688 Shader Processing Units and the GeForce GTX 1060 Gigabyte GTX G1 Gaming 6GB has 1280. However, the actual shader performance of the GTX 660 Ti is 2634 and the actual shader performance of the GTX 1060 is 3126. The GTX 1060 having 492 better shader performance is not particularly notable, as altogether the GTX 660 Ti performs better when taking into account other relevant data.

The GTX 1060 transistor size technology is 12 nm (nanometers) smaller than the GTX 660 Ti. This means that the GTX 1060 is expected to run slightly cooler and achieve higher clock frequencies than the GTX 660 Ti.

The GeForce GTX 660 Ti SLI requires 300 Watts to run and the GeForce GTX 1060 Gigabyte GTX G1 Gaming 6GB requires 120 Watts. We would recommend a PSU with at least 400 Watts for the GTX 1060, but we do not have a recommended PSU wattage for the GTX 660 Ti. The GTX 660 Ti requires 180 Watts more than the GTX 1060 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 1060.

GPU Mini Review

Mini ReviewGeForce GTX 660 Ti SLI is a solution of two 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 300 Watt though the average power consumption should be slightly lower.
Even the most demanding games will run at the highest settings.
The GeForce GTX 1060 Gigabyte GTX G1 Gaming is a Performance Graphics Card based on the Pascal Architecture.

It equips a GPU Codenamed P106-400-A1 which is a First Gen Pascal GPU amd has 10 SM activated, offering 1280 Shader Processing Units, 80 TMUs and 48 ROPs.

The central unit runs at 1594MHz and goes up to 1809MHz, in Turbo Mode.

The GPU accesses a 6GB frame buffer of Fast GDDR5, through a 192-bit memory interface, while the Memory Clock Operates at 2002MHz.

Power Consumption
With a rated board TDP of 120W, it requires at least a 400W PSU with one available 6-pin connector.

The GeForce GTX 1060 Gigabyte GTX G1 Gaming is a high level graphics card that can competently handle triple A titles from 2016. In full HD 1080p resolution it can confidently maintain 60+ frames per second on very high graphics settings. With the graphics adjusted down to High/Medium it can also handle between 50-60 fps on 1440p.

System Suggestions
GeForce GTX 1060 Gigabyte GTX G1 Gaming is best suited for resolutions up to and including 2560x1440. We recommend a High-End Processor and 8GB of RAM for Optimal Performance.
