In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 1660 PNY XLR8 Gaming Overclocked Single Fan 6GB are significantly better than the Nvidia GeForce GTX 760 Ti (OEM).

The GTX 1660 has a 615 MHz higher core clock speed but 24 fewer Texture Mapping Units than the GTX 760 Ti. The lower TMU count doesn't matter, though, as altogether the GTX 1660 manages to provide 32.1 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 1660 has a 615 MHz higher core clock speed and 16 more Render Output Units than the GTX 760 Ti. This results in the GTX 1660 providing 44.1 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 1660 was released over three years more recently than the GTX 760 Ti, and so the GTX 1660 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GTX 760 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 1660 has 4096 MB more video memory than the GTX 760 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 760 Ti has 0.2 GB/sec greater memory bandwidth than the GTX 1660, which means that the memory performance of the GTX 760 Ti is marginally better than the GTX 1660.

The GeForce GTX 1660 PNY XLR8 Gaming Overclocked Single Fan 6GB has 1408 Shader Processing Units and the GeForce GTX 760 Ti (OEM) has 1344. However, the actual shader performance of the GTX 1660 is 2577 and the actual shader performance of the GTX 760 Ti is 1317. The GTX 1660 having 1260 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 1660 delivers a massively smoother and more efficient experience when processing graphical data than the GTX 760 Ti.

The GTX 1660 transistor size technology is 16 nm (nanometers) smaller than the GTX 760 Ti. This means that the GTX 1660 is expected to run slightly cooler and achieve higher clock frequencies than the GTX 760 Ti.

The GeForce GTX 1660 PNY XLR8 Gaming Overclocked Single Fan 6GB requires 130 Watts to run and the GeForce GTX 760 Ti (OEM) requires 170 Watts. We would recommend a PSU with at least 450 Watts for the GTX 1660 and a PSU with at least 500 Watts for the GTX 760 Ti. The GTX 760 Ti requires 40 Watts more than the GTX 1660 to run. The difference is significant enough that the GTX 760 Ti may have a slight adverse affect on your yearly electricity bills in comparison to the GTX 1660.
