In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7870 MSI Hawk Edition are marginally better than the Nvidia GeForce GTX 660 Zotac AMP Edition.

The HD 7870 has a 54 MHz higher core clock speed and the same number of Texture Mapping Units as the GTX 660. This results in the HD 7870 providing 4.3 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 HD 7870 has a 54 MHz higher core clock speed and 8 more Render Output Units than the GTX 660. This results in the HD 7870 providing 10.1 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 660 was released less than a year after the HD 7870, and so they are likely to have similar driver support for optimizing performance 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 GeForce GTX 660 Zotac AMP Edition and the Radeon HD 7870 MSI Hawk Edition have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GTX 660 has 5 GB/sec greater memory bandwidth than the HD 7870, which means that the memory performance of the GTX 660 is marginally better than the HD 7870.

The GeForce GTX 660 Zotac AMP Edition has 960 Shader Processing Units and the Radeon HD 7870 MSI Hawk Edition has 1280. However, the actual shader performance of the GTX 660 is 1067 and the actual shader performance of the HD 7870 is 1197. The HD 7870 having 130 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7870 delivers a marginally smoother and more efficient experience when processing graphical data than the GTX 660.

GPU Mini Review

Mini ReviewGeForce GTX 660 Zotac AMP Edition a special edition of GeForce GTX 660.
The new features include a new cooling system and in terms of overclocking, the base-clock was increased from 980MHz to 1046MHz and the boost clock can now reach 1111MHz, instead of 1033MHz. The memory clock was raised to 1652MHz.
Benchmarks indicate a 5.5% performance when compared to the reference card.
Radeon HD 7870 MSI Hawk Edition is a special edition of the powerful Radeon HD 7870. See the standard version for more information about it.
The differences include an increase in the core-clock that went from 1000MHz to 1100MHz and a new efficient cooling system.
Benchmarks indicate a 5% performance boost when compared to the standard Radeon HD 7870.
All games, including demanding ones, will run on the highest settings.
