In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 640 v3 Zotac 1GB Edition are very slightly better than the Nvidia GeForce GT 640.
The GT 640 has a 144 MHz higher core clock speed than the GeForce GT 640, but the GeForce GT 640 has 16 more Texture Mapping Units than the GT 640. As a result, the GeForce GT 640 exhibits a 12.2 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 144 MHz higher core clock speed than the GeForce GT 640, but the GeForce GT 640 has 8 more Render Output Units than the GT 640. As a result, the GeForce GT 640 exhibits a 6 GPixel/s better Pixel Fill Rate than the GT 640. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.
The GT 640 was released less than a year after the GeForce GT 640, and so they are likely to have similar driver support for optimizing performance when running the latest games.
The GeForce GT 640 has 1024 MB more video memory than the GT 640, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the GT 640 has superior memory performance.
The GT 640 has 11.6 GB/sec greater memory bandwidth than the GeForce GT 640, which means that the memory performance of the GT 640 is slightly better than the GeForce GT 640.
Both the GeForce GT 640 v3 Zotac 1GB Edition and the GeForce GT 640 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 GeForce GT 640 is 346. 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 GeForce GT 640 v3 Zotac 1GB Edition requires 49 Watts to run and the GeForce GT 640 requires 65 Watts. We would recommend a PSU with at least 350 Watts for the GT 640 and a PSU with at least 350 Watts for the GeForce GT 640. The GeForce GT 640 requires 16 Watts more than the GT 640 to run. The difference is not significant enough for the GeForce GT 640 to have a noticeably larger impact on your yearly electricity bills than the GT 640.

| Mini Review | 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 Remains the same and the Frame Buffer was halved to 1GB which is adequate for the Graphics Card and will not decrease its performance. 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 1GB Edition is as fast as the reference GeForce GT 640 v3. | 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. | |||
