In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660 Zotac AMP Edition are massively better than the AMD Radeon HD 5670 512MB.

The GTX 660 has a 271 MHz higher core clock speed and 60 more Texture Mapping Units than the HD 5670. This results in the GTX 660 providing 68.2 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 271 MHz higher core clock speed and 16 more Render Output Units than the HD 5670. This results in the GTX 660 providing 18.9 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 a year more recently than the HD 5670, 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 HD 5670.

The GTX 660 has 1536 MB more video memory than the HD 5670, 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 94.6 GB/sec greater memory bandwidth than the HD 5670, which means that the memory performance of the GTX 660 is massively better than the HD 5670.

The GeForce GTX 660 Zotac AMP Edition has 960 Shader Processing Units and the Radeon HD 5670 512MB has 400. However, the actual shader performance of the GTX 660 is 1067 and the actual shader performance of the HD 5670 is 202. The GTX 660 having 865 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 5670.

The GTX 660 transistor size technology is 12 nm (nanometers) smaller than the HD 5670. This means that the GTX 660 is expected to run slightly cooler and achieve higher clock frequencies than the HD 5670.

The Radeon HD 5670 512MB requires 61 Watts to run but there is no entry for the GTX 660. We would recommend a PSU with at least 400 Watts for the HD 5670, but we do not have a recommended PSU wattage for 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.
The Evergreen series is a family of GPUs developed by AMD graphics products division. The existence was spotted on a presentation slide from AMD Technology Analyst Day July 2007 as 'R8xx'. ATI held a press event in the USS Hornet museum on September 10, 2009 and announced ATI Eyefinity multi-display technology and specifications of the Radeon HD 5800 series' variants. The first variants of the Radeon HD 5800 series were launched September 23, 2009, with the HD 5700 series launching October 12 and HD 5970 launching on November 18 The HD 5670, was launched on January 14, 2010, and the HD 5500 and 5400 series were launched in February of 2010, completing what has appeared to be most of ATI's Evergreen GPU lineup.
Demand so greatly outweighed supply that more than two months after launch, many online retailers were still having trouble keeping the 5800 and 5900 series in stock.
