In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R7 340 (OEM) are very slightly better than the Nvidia GeForce GT 640 v3 Zotac 2GB Edition.

The GT 640 has a 316 MHz higher core clock speed than the R7 340, but the R7 340 has 8 more Texture Mapping Units than the GT 640. As a result, the R7 340 exhibits a 0.8 GTexel/s better Texture Fill Rate than the GT 640. 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 316 MHz higher core clock speed than the R7 340 and the same number of Render Output Units. This results in the GT 640 providing 2.6 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 R7 340 was released over a year more recently than the GT 640, and so the R7 340 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 R7 340 (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 R7 340, which means that the memory performance of the GT 640 is slightly better than the R7 340.

Both the Radeon R7 340 (OEM) and the GeForce GT 640 v3 Zotac 2GB Edition have 384 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the GT 640 is 402 and by the R7 340 is 402. Knowing that the shader performance of the GT 640 is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.

The Radeon R7 340 (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 R7 340 and a PSU with at least 350 Watts for the GT 640. The R7 340 requires 1 Watts more than the GT 640 to run. The difference is not significant enough for the R7 340 to have a noticeably larger impact on your yearly electricity bills than the GT 640.

GPU Mini Review

Mini ReviewOverview
Radeon R5 340 (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 XT previously used on Radeon R5 250. It offers 384 Shader Processing Units, 24 TMUs and 8 ROPs. The central unit runs at 730MHz and goes up to 780MHz, in Turbo Mode.

Memory
The GPU accesses a 2GB frame buffer of 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 a direct rebrand of the fastest Radeon R7 240 Variant, which was never used by any manufacturer. Therefore, it offers exactly the same performance.

System Suggestions
We recommend a Strong Dual Core Processor (Intel Core i5 Quad Core/AMD FX Quad Core) and 8GB of RAM for a system with Radeon R5 350 (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.
