Compare any two graphics cards:
GeForce 9800 GX2 vs GeForce GT 440 3GB
IntroThe GeForce 9800 GX2 makes use of a 65 nm design. nVidia has set the core frequency at 600 MHz. The GDDR3 memory is set to run at a frequency of 1000 MHz on this model. It features 128 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.Compare those specs to the GeForce GT 440 3GB, which comes with core clock speeds of 594 MHz on the GPU, and 900 MHz on the 3072 MB of GDDR3 memory. It features 144 SPUs along with 24 TAUs and 24 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce 9800 GX2 should be a lot faster than the GeForce GT 440 3GB overall. (explain)
Texel RateThe GeForce 9800 GX2 will be a lot (approximately 439%) more effective at anisotropic filtering than the GeForce GT 440 3GB. (explain)
Pixel RateThe GeForce 9800 GX2 should be a lot (about 35%) more effective at anti-aliasing than the GeForce GT 440 3GB, and capable of handling higher screen resolutions while still performing well. (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. One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
