In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 640 are significantly better than the AMD FirePro W2100.

The GeForce GT 640 has a 272 MHz higher core clock speed and 12 more Texture Mapping Units than the FirePro W2100. This results in the GeForce GT 640 providing 16.3 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 272 MHz higher core clock speed and 8 more Render Output Units than the FirePro W2100. This results in the GeForce GT 640 providing 9.4 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 FirePro W2100 was released over a year more recently than the GeForce GT 640, and so the FirePro W2100 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 FirePro W2100 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 FirePro W2100 has 0.3 GB/sec greater memory bandwidth than the GeForce GT 640, which means that the memory performance of the FirePro W2100 is marginally better than the GeForce GT 640.

The FirePro W2100 has 320 Shader Processing Units and the GeForce GT 640 has 384. However, the actual shader performance of the FirePro W2100 is 185 and the actual shader performance of the GeForce GT 640 is 346. The GeForce GT 640 having 161 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GT 640 delivers a slightly smoother and more efficient experience when processing graphical data than the FirePro W2100.

The FirePro W2100 requires 26 Watts to run and the GeForce GT 640 requires 65 Watts. We would recommend a PSU with at least 350 Watts for the FirePro W2100 and a PSU with at least 350 Watts for the GeForce GT 640. The GeForce GT 640 requires 39 Watts more than the FirePro W2100 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 FirePro W2100.

GPU Mini Review

Mini ReviewOverview
FirePro W2100 is a Professional Graphics Card based on the Second Revision of the GCN Architecture.

Architecture
The GCN 1.1 Release adds support for AMD's TrueAudio Technology which does calculations of audio effects "better" than the CPU and further improves the Powertune Technology.

GPU
It equips a GPU Codenamed Oland PRO which has 5 Compute Units activated and thus offers 320 Shader Processing Units, 20 TMUs and 8 ROPs. The Central Unit Initially Operates at 630MHz and goes up to 680MHz, 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 11.2 Support (11.1 Hardware Default) and support for Crossfire, PowerTune Technology, Eyefinity, App Acceleration, HD3D, ZeroCore Power and other technologies.

Power Consumption
With a rated board TDP of 26W, it requires at least a 350W PSU and it relies entirely on the PCI Slot for power, meaning no extra connectors are required.

Performance
FirePro W2100 has a GPU configuration similar to Radeon R7 240 2GB. However, it is under-clocked and does not benefit from the game optimizations through its drivers.
As a result, it may perform over 15% worse than Radeon R7 240 2GB.

System Suggestions
We recommend a Modest Processor (Intel Core i3/AMD FX-4100) and 4GB of RAM for a system with FirePro W2100.
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.
