Compare any two graphics cards:
GeForce GT 310 vs GeForce GT 440 1.5GB
IntroThe GeForce GT 310 has a GPU core clock speed of 589 MHz, and the 512 MB of DDR2 RAM is set to run at 1000 MHz through a 64-bit bus. It also is comprised of 16 Stream Processors, 8 TAUs, and 4 Raster Operation Units.Compare that to the GeForce GT 440 1.5GB, which makes use of a 40 nm design. nVidia has clocked the core speed at 594 MHz. The GDDR3 memory is set to run at a speed of 900 MHz on this model. It features 144 SPUs along with 24 TAUs and 24 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GT 440 1.5GB should in theory be a lot faster than the GeForce GT 310 in general. (explain)
Texel RateThe GeForce GT 440 1.5GB is a lot (about 203%) better at texture filtering than the GeForce GT 310. (explain)
Pixel RateThe GeForce GT 440 1.5GB should be much (more or less 505%) more effective at full screen anti-aliasing than the GeForce GT 310, and also will be able to handle higher screen resolutions better. (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 (in units of MB per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 can be applied per second. This is calculated by multiplying the total number of texture units 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 processed per second. Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount 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 is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
