In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660 MSI Hawk 2GB Edition are massively better than the AMD Radeon HD 3850 X2.

The GTX 660 has a 416 MHz higher core clock speed and 48 more Texture Mapping Units than the HD 3850. This results in the GTX 660 providing 65.4 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 has a 416 MHz higher core clock speed but 8 fewer Render Output Units than the HD 3850. The lower ROP count doesn't matter, though, as altogether the GTX 660 manages to provide 4.6 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 660 was released over three years more recently than the HD 3850, and so the GTX 660 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the HD 3850 when running the latest games.

The GTX 660 has 1024 MB more video memory than the HD 3850, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 660 also has superior memory performance overall.

The GTX 660 has 38.2 GB/sec greater memory bandwidth than the HD 3850, which means that the memory performance of the GTX 660 is noticeably better than the HD 3850.

The GeForce GTX 660 MSI Hawk 2GB Edition has 960 Shader Processing Units and the Radeon HD 3850 X2 has 640. However, the actual shader performance of the GTX 660 is 1104 and the actual shader performance of the HD 3850 is 428. The GTX 660 having 676 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 660 delivers a massively smoother and more efficient experience when processing graphical data than the HD 3850.

The GTX 660 transistor size technology is 27 nm (nanometers) smaller than the HD 3850. This means that the GTX 660 is expected to run slightly cooler and achieve higher clock frequencies than the HD 3850.

The Radeon HD 3850 X2 requires 140 Watts to run but there is no entry for the GTX 660. We would recommend a PSU with at least 450 Watts for the HD 3850, but we do not have a recommended PSU wattage for the GTX 660.

GPU Mini Review

Mini ReviewGeForce GTX 660 MSI Hawk 2GB Edition a special edition of GeForce GTX 660.
The new features include the Twin Frozr III Thermal Design cooling solution which, according to MSI, generates 20% more airflow than traditional fan design.
In terms of overclocking, the base-clock was increased from 980MHz to 1085MHz and the boost clock can now reach 1150MHz, instead of 1033MHz. The memory clock was left untouched.
The overclocking is therefore extreme and the performance boost is around 8% when compared to the standard GeForce GTX 660.
Radeon HD 3850 X2 (not Crossfire) is a dual-graphics solution of two Radeon HD 3850.
This combination is expected to offer almost the same performance as Radeon HD 3850 Crossfired while consuming slightly less power. However, and just like Crossfire, its performance also relies a lot on proper driver support.
Today's modern demanding games will have to be played using the medium preset but with fluent frame rates. However, DirectX 11 games aren't supported.
