In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R7 240 v2 HIS iCooler Boost Clock 2GB Edition are marginally better than the Nvidia GeForce GT 640.

The GeForce GT 640 has a 172 MHz higher core clock speed and 12 more Texture Mapping Units than the R7 240. This results in the GeForce GT 640 providing 14.3 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 GeForce GT 640 has a 172 MHz higher core clock speed and 8 more Render Output Units than the R7 240. This results in the GeForce GT 640 providing 8.6 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 240 was released over a year more recently than the GeForce GT 640, and so the R7 240 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce GT 640.

The Radeon R7 240 v2 HIS iCooler Boost Clock 2GB Edition and the GeForce GT 640 have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The R7 240 has 45.1 GB/sec greater memory bandwidth than the GeForce GT 640, which means that the memory performance of the R7 240 is noticeably better than the GeForce GT 640.

The Radeon R7 240 v2 HIS iCooler Boost Clock 2GB Edition has 320 Shader Processing Units and the GeForce GT 640 has 384. However, the actual shader performance of the R7 240 is 212 and the actual shader performance of the GeForce GT 640 is 346. The GeForce GT 640 having 134 better shader performance is not particularly notable, as altogether the R7 240 performs better when taking into account other relevant data.

The Radeon R7 240 v2 HIS iCooler Boost Clock 2GB Edition requires 30 Watts to run and the GeForce GT 640 requires 65 Watts. We would recommend a PSU with at least 400 Watts for the R7 240 and a PSU with at least 350 Watts for the GeForce GT 640. The GeForce GT 640 requires 35 Watts more than the R7 240 to run. The difference is significant enough that the GeForce GT 640 may have a slight adverse affect on your yearly electricity bills in comparison to the R7 240.

GPU Mini Review

Mini ReviewOverview
Radeon R7 240 v2 HIS iCooler Boost Clock 2GB Edition is a special edition of AMD's Middle-Class Radeon R7 240 v2, created by HIS.

Overclock: Central Unit
None.

Overclock: Memory Clock
None.

Memory: Frame Buffer
The GPU can fill up a Memory Pool of up to 2GB. However, because the GPU itself is too weak to work under other circumstances in which 2GB of Memory are needed - such as 1080p Gaming, a Large Frame Buffer is mostly a Gimmick.

Cooling Solution
The card is equipped with iCooler, making it extremely quiet and noise level is less than 28dB.

Performance
Benchmarks Indicate no Performance Boost over the Reference Radeon R7 240 v2.
Overview
GeForce GT 640 is a Middle-Class Graphics Card based on the first revision of the Kepler Architecture.

Architecture
The Kepler Architecture was NVIDIA's big step to power efficiency. Each Stream Multiprocessor (SMX) now hosts 192 Shader Processing Units - against the 48 of older Fermi Architecture, and has been redesigned being now clocked at the same speed of the Central Unit. This means they are more energy efficient and will consequently lead to cooler operating temperatures. However, it also means they are weaker. It can be said that one Fermi SMX is as fast as 2 Kepler SMXs.
Additionally, and not available in all GPUs, Kepler also introduced the Boost Clock Feature. The Boost Clock is an even higher Clock Speed activated when in gaming mode and becomes the effective speed of the GPU.

GPU
It equips a GPU Codenamed GK107-300-A2 which has 2 Stream Multiprocessor activated and thus offers 384 Shader Processing Units, 32 TMUs and 16 ROPs. The Central Unit is clocked at 902MHz.

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 891MHz.

Features
DirectX 11.0 Support (11.0 Hardware Default) and support for Optimus, CUDA, OpenCL, DirectCompute, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies

Power Consumption
With a rated board TDP of 65W, it requires at least a 350W PSU and it relies entirely on the PCI Slot for power, meaning no extra connectors are required.

Performance
Gaming benchmarks put its performance on average with Radeon HD 6670.

System Suggestions
We recommend a Modest Processor (Intel Core i3) and 8GB of RAM for a system with GeForce GT 640.
