Compare any two graphics cards:
GeForce GT 440 1.5GB vs GeForce GTX 260 216SP 55 nm
IntroThe GeForce GT 440 1.5GB features a GPU core clock speed of 594 MHz, and the 1536 MB of GDDR3 memory runs at 900 MHz through a 192-bit bus. It also is comprised of 144 SPUs, 24 Texture Address Units, and 24 Raster Operation Units.Compare all that to the GeForce GTX 260 216SP 55 nm, which uses a 55 nm design. nVidia has set the core frequency at 576 MHz. The GDDR3 RAM is set to run at a speed of 999 MHz on this particular card. It features 216 SPUs along with 72 Texture Address Units and 28 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 260 216SP 55 nm should theoretically be much better than the GeForce GT 440 1.5GB overall. (explain)
Texel RateThe GeForce GTX 260 216SP 55 nm should be a lot (more or less 191%) faster with regards to texture filtering than the GeForce GT 440 1.5GB. (explain)
Pixel RateThe GeForce GTX 260 216SP 55 nm should be a bit (more or less 13%) faster with regards to anti-aliasing than the GeForce GT 440 1.5GB, and also will be able to handle higher resolutions without losing too much performance. (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: Bandwidth is the max amount of data (counted in megabytes per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
