In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 1660 KFA2 EX 1-Click OC 6GB are significantly better than the Nvidia GeForce GTX 770 DirectCU II 2GB OC Edition.

The GTX 1660 has a 472 MHz higher core clock speed than the GTX 770, but the GTX 770 has 40 more Texture Mapping Units than the GTX 1660. As a result, the GTX 770 exhibits a 0.80000000000001 GTexel/s better Texture Fill Rate than the GTX 1660. 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 472 MHz higher core clock speed and 16 more Render Output Units than the GTX 770. This results in the GTX 1660 providing 39.5 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 770, 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 770 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 770, 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 770 has 32.3 GB/sec greater memory bandwidth than the GTX 1660, which means that the memory performance of the GTX 770 is noticeably better than the GTX 1660.

The GeForce GTX 1660 KFA2 EX 1-Click OC 6GB has 1408 Shader Processing Units and the GeForce GTX 770 DirectCU II 2GB OC Edition has 1536. However, the actual shader performance of the GTX 1660 is 2598 and the actual shader performance of the GTX 770 is 1705. The GTX 1660 having 893 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 1660 delivers a significantly smoother and more efficient experience when processing graphical data than the GTX 770.

The GTX 1660 transistor size technology is 16 nm (nanometers) smaller than the GTX 770. This means that the GTX 1660 is expected to run slightly cooler and achieve higher clock frequencies than the GTX 770.

The GeForce GTX 1660 KFA2 EX 1-Click OC 6GB requires 130 Watts to run but there is no entry for the GeForce GTX 770 DirectCU II 2GB OC Edition. We would recommend a PSU with at least 450 Watts for the GTX 1660 and a PSU with at least 550 Watts for the GTX 770. The GTX 770 has been recommended a PSU with 100 Watts more than the GTX 1660. The difference is significant enough that the GTX 770 may have an adverse affect on your yearly electricity bills in comparison to the GTX 1660.

GPU Mini Review

Mini ReviewOverview
The GeForce GTX 1660 KFA2 EX 1-Click OC 6GB is an entry to mid-level Nvidia graphics card which launched on March 14th, 2019. The GeForce GTX 1660 is designed to compete against AMD's more affordable gaming cards such as the RX 570 and the RX 580, and replaces the outgoing GTX 1060. The GeForce GTX 1660 KFA2 EX 1-Click OC 6GB is a dual-slot graphics card with a dual-fan 90mm cooling solution, copper heat pipes, RGB Effect lighting, and an anti-bend back plate. This graphics card has average overclocking potential.

Architecture
The Turing GPU architecture aims for 30-50% as much performance as the previous-gen Pascal Architecture.

GPU
It equips a GPU codenamed Turing TU116, more specifically the TU166-300-A1, which has 22 SM activated and thus 1408 Shader Processing Units, 88 TMUs, and 48 ROPs. The central unit runs at 1530 MHz and goes up to 1845 MHz with the Boost Clock, providing a small 3% overclock versus the reference model.

Memory
The GPU accesses a 6GB frame buffer of fast GDDR5 through a 192-bit memory interface, while the memory clock Operates at 2001MHz, or 8GHz effective.

Power Consumption
With a rated board TDP of 130W, this graphics card requires one 6-pin power connector and a minimum of a 450W power supply.

Performance
The GeForce GTX 1660 will enable medium to high graphics performance on modern AAA 2018 released games. Although there will be variations on this frame rate we expect this card to deliver around 50+ FPS on High graphics settings at 1080p screen resolution.
Comparatively, this card will have slightly faster performance than the GTX 1060.

System Suggestions
The GeForce GTX 1660 KFA2 EX 1-Click OC 6GB is best suited for resolutions up to and including 2560x1440, so our recommendation would be to use 1920x1080 in order to get the most out of your settings. We recommend a high-end processor such as the i5-8500 and 12GB of RAM for optimal performance.
GeForce GTX 770 DirectCU II 2GB OC Edition is a special edition of the high-end GeForce GTX 770.
This edition comes with a custom cooling solution, 20% cooler and 3X quieter, which by itself should allow a slight performance boost, as GeForce GTX 770 benefits from the GPU Boost 2.0 technology.
Also, it has been overclocked out of the box from 1046MHz to 1058MHz while its boost clock is now of 1110MHz. The memory clock was left untouched.
Benchmarks indicate a 4% performance boost when compared to the reference card and so this edition performs very slightly better than GeForce GTX 590.
