In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 640 v3 Zotac 2GB Edition are noticeably better than the AMD Radeon HD 5670 1024MB.

The GT 640 has a 271 MHz higher core clock speed but 4 fewer Texture Mapping Units than the HD 5670. The lower TMU count doesn't matter, though, as altogether the GT 640 manages to provide 1.2 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 GT 640 has a 271 MHz higher core clock speed than the HD 5670 and the same number of Render Output Units. This results in the GT 640 providing 2.2 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 GT 640 was released over three years more recently than the HD 5670, and so the GT 640 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the HD 5670 when running the latest games.

The GT 640 has 1024 MB more video memory than the HD 5670, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The HD 5670 has 23.9 GB/sec greater memory bandwidth than the GT 640, which means that the memory performance of the HD 5670 is slightly better than the GT 640.

The GeForce GT 640 v3 Zotac 2GB Edition has 384 Shader Processing Units and the Radeon HD 5670 1024MB has 400. However, the actual shader performance of the GT 640 is 402 and the actual shader performance of the HD 5670 is 155. The GT 640 having 247 better shader performance is not particularly notable, as altogether the HD 5670 performs better when taking into account other relevant data.

The GT 640 transistor size technology is 12 nm (nanometers) smaller than the HD 5670. This means that the GT 640 is expected to run slightly cooler and achieve higher clock frequencies than the HD 5670.

The GeForce GT 640 v3 Zotac 2GB Edition requires 49 Watts to run and the Radeon HD 5670 1024MB requires 64 Watts. We would recommend a PSU with at least 350 Watts for the GT 640 and a PSU with at least 400 Watts for the HD 5670. The HD 5670 requires 15 Watts more than the GT 640 to run. The difference is not significant enough for the HD 5670 to have a noticeably larger impact on your yearly electricity bills than the GT 640.

GPU Mini Review

Mini ReviewOverview
GeForce GT 640 v3 Zotac 2GB Edition is a special edition of NVIDIA's Middle-Class GeForce GT 640 v3, created by Zotac.

Overclock: Central Unit
The Central Unit runs at the same speed.

Overclock: Memory Clock
The Operating Memory Clock and the Frame Buffer remain the same.

Cooling Solution
The Cooling System has been replaced by Zotac's Silent Cooling Solution.

Performance
Without Overclocking Out of The Box, GeForce GT 640 v3 Zotac 2GB Edition is as fast as the reference GeForce GT 640 v3.
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.
