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 R5 330 (OEM).

The GT 640 has a 216 MHz higher core clock speed but 4 fewer Texture Mapping Units than the R5 330. The lower TMU count doesn't matter, though, as altogether the GT 640 manages to provide 0.099999999999998 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 216 MHz higher core clock speed than the R5 330 and the same number of Render Output Units. This results in the GT 640 providing 1.8 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 R5 330 was released over a year more recently than the GT 640, and so the R5 330 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GT 640.

The Radeon R5 330 (OEM) and the GeForce GT 640 v3 Zotac 2GB Edition have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GT 640 has 11.3 GB/sec greater memory bandwidth than the R5 330, which means that the memory performance of the GT 640 is slightly better than the R5 330.

The Radeon R5 330 (OEM) has 320 Shader Processing Units and the GeForce GT 640 v3 Zotac 2GB Edition has 384. However, the actual shader performance of the R5 330 is 233 and the actual shader performance of the GT 640 is 402. The GT 640 having 169 better shader performance and an altogether better performance when taking into account other relevant data means that the GT 640 delivers a marginally smoother and more efficient experience when processing graphical data than the R5 330.

The Radeon R5 330 (OEM) requires 50 Watts to run and the GeForce GT 640 v3 Zotac 2GB Edition requires 49 Watts. We would recommend a PSU with at least 450 Watts for the R5 330 and a PSU with at least 350 Watts for the GT 640. The R5 330 requires 1 Watts more than the GT 640 to run. The difference is not significant enough for the R5 330 to have a noticeably larger impact on your yearly electricity bills than the GT 640.

GPU Mini Review

Mini ReviewOverview
Radeon R5 330 (OEM) is an OEM only, Middle-Class Graphics Card based on the second revision of the Graphics Core Next Architecture.

Architecture
The GCN 1.1 revision of the Graphics Core Next Architecture adds new important technologies and is largely oriented for energy efficiency. New technologies such as PowerTune and TrueAudio are the biggest additions as well as DirectX 11.2 support.

GPU
It equips a GPU codenamed Oland PRO previously used on Radeon R5 240. It offers 320 Shader Processing Units, 20 TMUs and 8 ROPs. The central unit runs at 830MHz and goes up to 855MHz, in Turbo Mode.

Memory
The GPU accesses a 2GB frame buffer of fast DDR3, through a 128-bit memory interface. The size of the frame buffer is exaggerated and in no way benefits the GPU. The Memory Clock Operates at 900MHz.

Features
DirectX 12.0 Support (11.0 Hardware Default) and support for Crossfire, Mantle, PowerTune, Eyefinity, ZeroCore, HD3D, App Acceleration and other technologies.

Power Consumption
With a rated board TDP of 50W, it requires at least a 450W PSU and relies entirely on the PCI slot for power.

Performance
Radeon R5 340 (OEM) is essentially a fast Radeon R7 240. Therefore, its performance stands somewhere between Radeon R7 240 and the faster Radeon R7 240 V2.

System Suggestions
We recommend a Modest Dual Core Processor (Intel Core i3 Quad Core/AMD FX Quad Core) and 4GB of RAM for a system with Radeon R5 330 (OEM).
Overview
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.
