Compare any two graphics cards:
GeForce GT 230 vs GeForce GT 440 1.5GB
IntroThe GeForce GT 230 makes use of a 40 nm design. nVidia has clocked the core speed at 550 MHz. The DDR3 memory is set to run at a speed of 800 MHz on this model. It features 32 SPUs as well as 16 TAUs and 8 Rasterization Operator Units.Compare those specifications to the GeForce GT 440 1.5GB, which features clock speeds of 594 MHz on the GPU, and 900 MHz on the 1536 MB of GDDR3 memory. It features 144 SPUs as well as 24 Texture Address Units and 24 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GT 440 1.5GB should be a little bit faster than the GeForce GT 230 overall. (explain)
Texel RateThe GeForce GT 440 1.5GB will be much (approximately 62%) better at anisotropic filtering than the GeForce GT 230. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GT 440 1.5GB is superior to the GeForce GT 230, 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 maximum amount of data (counted in megabytes per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
