In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 1660 Gigabyte Gaming OC 6GB are marginally better than the AMD Radeon HD 7950 3-way Crossfire.

The GTX 1660 has a 730 MHz higher core clock speed than the HD 7950, but the HD 7950 has 248 more Texture Mapping Units than the GTX 1660. As a result, the HD 7950 exhibits a 134.2 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 730 MHz higher core clock speed than the HD 7950, but the HD 7950 has 48 more Render Output Units than the GTX 1660. As a result, the HD 7950 exhibits a 3.4 GPixel/s better Pixel Fill Rate than the GTX 1660. 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 HD 7950, 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 HD 7950 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 HD 7950 has 3072 MB more video memory than the GTX 1660, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the HD 7950 also has superior memory performance overall.

The HD 7950 has 527.9 GB/sec greater memory bandwidth than the GTX 1660, which means that the memory performance of the HD 7950 is massively better than the GTX 1660.

The GeForce GTX 1660 Gigabyte Gaming OC 6GB has 1408 Shader Processing Units and the Radeon HD 7950 3-way Crossfire has 5376. However, the actual shader performance of the GTX 1660 is 2619 and the actual shader performance of the HD 7950 is 3656. The HD 7950 having 1037 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7950 delivers a massively smoother and more efficient experience when processing graphical data than the GTX 1660.

The GTX 1660 transistor size technology is 16 nm (nanometers) smaller than the HD 7950. This means that the GTX 1660 is expected to run slightly cooler and achieve higher clock frequencies than the HD 7950.

The GeForce GTX 1660 Gigabyte Gaming OC 6GB requires 150 Watts to run and the Radeon HD 7950 3-way Crossfire requires 540 Watts. We would recommend a PSU with at least 450 Watts for the GTX 1660. The HD 7950 requires 390 Watts more than the GTX 1660 to run. The difference is significant enough that the HD 7950 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 Gigabyte Gaming 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 Gigabyte Gaming OC 6GB is a dual-slot graphics card with a triple-fan Windforce 3X cooling solution, RGB Fusion 2.0 lighting, and a protective back plate. This graphics card has above 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 1860 MHz with the Boost Clock, providing a 4% 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 150W, this graphics card requires one 8-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 Gigabyte Gaming 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.
Radeon HD 7950 3-way Crossfire is a solution of three Radeon HD 7950 put together using AMD'S Crossfire technology.
Check the page of Radeon HD 7950 to know more about its chip.
Crossfire 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 somewhat superior to a single Radeon HD 7990 performing by itself it might be worse (depending on whether or not the 3D game supports crossfire or in the graphics driver) than a single Radeon HD 7950. Expect this combination to draw up to 540 Watt though the average power consumption should be slightly lower.
Even the most demanding games will run at the highest settings.
