In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 580 Gigabyte UD rev 1.0 Edition are very slightly better than the Nvidia GeForce GTX 660 Zotac AMP Edition.

The GTX 660 has a 251 MHz higher core clock speed and 16 more Texture Mapping Units than the GTX 580. This results in the GTX 660 providing 32.8 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 251 MHz higher core clock speed than the GTX 580, but the GTX 580 has 24 more Render Output Units than the GTX 660. As a result, the GTX 580 exhibits a 13.1 GPixel/s better Pixel Fill Rate than the GTX 660. 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 a year more recently than the GTX 580, and so the GTX 660 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 580.

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 660 has 512 MB more video memory than the GTX 580, 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 580 has 33.8 GB/sec greater memory bandwidth than the GTX 660, which means that the memory performance of the GTX 580 is noticeably better than the GTX 660.

The GeForce GTX 580 Gigabyte UD rev 1.0 Edition has 512 Shader Processing Units and the GeForce GTX 660 Zotac AMP Edition has 960. However, the actual shader performance of the GTX 580 is 814 and the actual shader performance of the GTX 660 is 1067. The GTX 660 having 253 better shader performance is not particularly notable, as altogether the GTX 580 performs better when taking into account other relevant data.

The GTX 660 transistor size technology is 12 nm (nanometers) smaller than the GTX 580. This means that the GTX 660 is expected to run slightly cooler and achieve higher clock frequencies than the GTX 580.

We would recommend a PSU with at least 600 Watts for the GTX 580.

GPU Mini Review

Mini ReviewGeForce GTX 580 Gigabyte UD rev 1.0 Edition is a special edition of the powerful GeForce GTX 580.
The differences include an increase in the core-clock that went from 772MHz to 795MHz and a better cooling system called GIGABYTE WINDFORCE 3X with vapor chamber anti-turblence. Benchmarks indicate a performance boost of about 1.5% when compared to the standard GeForce GTX 580.
GeForce 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.
