In terms of overall gaming performance, the graphical capabilities of the Nvidia Quadro FX 5800 are marginally better than the Nvidia GeForce GT 640.

The GeForce GT 640 was released over three years more recently than the Quadro FX 5800, and so the GeForce GT 640 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the Quadro FX 5800 when running the latest games.

The Quadro FX 5800 has 2048 MB more video memory than the GeForce GT 640, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the Quadro FX 5800 also has superior memory performance overall.

The Quadro FX 5800 has 73.9 GB/sec greater memory bandwidth than the GeForce GT 640, which means that the memory performance of the Quadro FX 5800 is much better than the GeForce GT 640.

The GeForce GT 640 has 384 Shader Processing Units and the Quadro FX 5800 has 240. However, the actual shader performance of the GeForce GT 640 is 346 and the actual shader performance of the Quadro FX 5800 is 156. The GeForce GT 640 having 190 better shader performance is not particularly notable, as altogether the Quadro FX 5800 performs better when taking into account other relevant data.

The GeForce GT 640 transistor size technology is 37 nm (nanometers) smaller than the Quadro FX 5800. This means that the GeForce GT 640 is expected to run much cooler and achieve higher clock frequencies than the Quadro FX 5800. While they exhibit similar graphical performance, the GeForce GT 640 should consume less power than the Quadro FX 5800.

The GeForce GT 640 requires 65 Watts to run and the Quadro FX 5800 requires 189 Watts. We would recommend a PSU with at least 350 Watts for the GeForce GT 640 and a PSU with at least 750 Watts for the Quadro FX 5800. The Quadro FX 5800 requires 124 Watts more than the GeForce GT 640 to run. The difference is significant enough that the Quadro FX 5800 may have an adverse affect on your yearly electricity bills in comparison to the GeForce GT 640.

GPU Mini Review

Mini ReviewOverview
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.
The Quadro® FX 5800 ultra-high-end solution gives geophysicists, designers, scientists, engineers, and other technical professionals visual supercomputing from their desktops. Professional applications take advantage of the advanced feature set of the Quadro FX 5800, including 4GB of frame buffer, providing professionals with the right set of tools to deliver results that push visualization beyond traditional 3D.
