Compare any two graphics cards:
GeForce GT 440 1.5GB vs GeForce GTX 285 2GB
IntroThe GeForce GT 440 1.5GB uses a 40 nm design. nVidia has set the core frequency at 594 MHz. The GDDR3 RAM runs at a speed of 900 MHz on this specific card. It features 144 SPUs as well as 24 TAUs and 24 Rasterization Operator Units.Compare that to the GeForce GTX 285 2GB, which features core clock speeds of 648 MHz on the GPU, and 1242 MHz on the 2048 MB of GDDR3 RAM. It features 240 SPUs along with 80 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 285 2GB should be 268% faster than the GeForce GT 440 1.5GB in general, due to its greater bandwidth. (explain)
Texel RateThe GeForce GTX 285 2GB should be a lot (about 264%) faster with regards to texture filtering than the GeForce GT 440 1.5GB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 285 2GB is the winner, and very much so. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of information (measured in megabytes per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
