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 6570.

The GT 640 has a 396 MHz higher core clock speed but 8 fewer Texture Mapping Units than the Radeon HD 6570. The lower TMU count doesn't matter, though, as altogether the GT 640 manages to provide 1.1 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 396 MHz higher core clock speed than the Radeon HD 6570 and the same number of Render Output Units. This results in the GT 640 providing 3.2 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 a year more recently than the Radeon HD 6570, and so the GT 640 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the Radeon HD 6570.

The GT 640 has 1024 MB more video memory than the Radeon HD 6570, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The Radeon HD 6570 has 23.9 GB/sec greater memory bandwidth than the GT 640, which means that the memory performance of the Radeon HD 6570 is slightly better than the GT 640.

The GeForce GT 640 v3 Zotac 2GB Edition has 384 Shader Processing Units and the Radeon HD 6570 has 480. However, the actual shader performance of the GT 640 is 402 and the actual shader performance of the Radeon HD 6570 is 156. The GT 640 having 246 better shader performance is not particularly notable, as altogether the Radeon HD 6570 performs better when taking into account other relevant data.

The GT 640 transistor size technology is 12 nm (nanometers) smaller than the Radeon HD 6570. This means that the GT 640 is expected to run slightly cooler and achieve higher clock frequencies than the Radeon HD 6570.

The GeForce GT 640 v3 Zotac 2GB Edition requires 49 Watts to run and the Radeon HD 6570 requires 60 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 Radeon HD 6570. The Radeon HD 6570 requires 11 Watts more than the GT 640 to run. The difference is not significant enough for the Radeon HD 6570 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.
Overview
Radeon HD 6570 is a middle-class Graphics Card based on the second revision of the Terascale Architecture.

Architecture
The Second variant of the Terascale 2 Architecture is still manufactured with a 40nm technology and despite allowing more Stream Cores, their design remains more or less the same compared to the first variant.

GPU
It equips a GPU codenamed Turks PRO which has 6 Compute Units activated and thus offers 480 Shader Processing Units, 24 TMUs and 8 ROPs.

Memory
The GPU accesses a 1GB frame buffer of fast GDDR5, through a 128-bit memory interface. The memory clock operates at 1000MHz. The size of the frame buffer is adequate.

Features
DirectX 11.0 Support (11.0 Hardware Default) and support for Crossfire, HD3D, Eyefinity, App Acceleration, PowerPlay and other technologies.

Cooling Solution
The Cooling Solution consists of a Single-Fan.

Power Consumption
With a rated board TDP of 60W, it requires at least a 400W PSU and it relies entirely on the PCI Slot for power, meaning no extra connectors are required.

Performance
Gaming benchmarks put its performance somewhat above GeForce GT 440, meaning GeForce GTS 450 is still much faster.

System Suggestions
We recommend a modest processor (Intel Celeron) and 4GB of RAM for a system with Radeon HD 6570.
