In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R7 250 v2 2GB are noticeably better than the Nvidia GeForce GT 640.

The R7 250 has a 98 MHz higher core clock speed than the GeForce GT 640, but the GeForce GT 640 has 8 more Texture Mapping Units than the R7 250. As a result, the GeForce GT 640 exhibits a 4.9 GTexel/s better Texture Fill Rate than the R7 250. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The R7 250 has a 98 MHz higher core clock speed than the GeForce GT 640, but the GeForce GT 640 has 8 more Render Output Units than the R7 250. As a result, the GeForce GT 640 exhibits a 6.4 GPixel/s better Pixel Fill Rate than the R7 250. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The R7 250 was released over a year more recently than the GeForce GT 640, and so the R7 250 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 GeForce GT 640 and the Radeon R7 250 v2 2GB have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The R7 250 has 0.3 GB/sec greater memory bandwidth than the GeForce GT 640, which means that the memory performance of the R7 250 is marginally better than the GeForce GT 640.

Both the GeForce GT 640 and the Radeon R7 250 v2 2GB have 384 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the GeForce GT 640 is 346 and by the R7 250 is 343. Knowing that the shader performance of the GeForce GT 640 is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.

The GeForce GT 640 requires 65 Watts to run and the Radeon R7 250 v2 2GB requires 65 Watts. We would recommend a PSU with at least 350 Watts for the GeForce GT 640 and a PSU with at least 400 Watts for the R7 250. The two GPUs require the same amount of wattage to run. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.

GPU Mini Review


Mini Review	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.				Note: This Graphics Card has 2 variants: one with DDR3 and another with GDDR5. This is the DDR3 Version. Radeon R7 250 v2 2GB offers a GCN 1.1 Core codenamed Oland PRO and thus features 384 Shader Processing Units, 24 TMUs and 8 ROPs, on a 128-bit bus width of standard DDR3. While the central unit runs at 1000MHz and goes up to 1050MHz, in Turbo Mode, the memory clock operates at 900MHz. With a rated board TDP of 65W, it requires no extra power connectors. Its performance is up to 10% lower than the original Radeon R7 250 which is equipped with fast GDDR5. However, at lower resolutions, both cards offer similar performance. It's worth mentioning that even an integrated Radeon R7 7850K offers better performance.
