Compare any two graphics cards:
GeForce GT 310 vs GeForce GTS 450
IntroThe GeForce GT 310 uses a 40 nm design. nVidia has clocked the core speed at 589 MHz. The DDR2 memory runs at a frequency of 1000 MHz on this specific model. It features 16 SPUs along with 8 Texture Address Units and 4 Rasterization Operator Units.Compare those specifications to the GeForce GTS 450, which has GPU core speed of 783 MHz, and 512 MB of GDDR5 RAM set to run at 902 MHz through a 128-bit bus. It also is made up of 192 SPUs, 32 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTS 450 will be 261% faster than the GeForce GT 310 overall, because of its higher data rate. (explain)
Texel RateThe GeForce GTS 450 is a lot (about 432%) better at texture filtering than the GeForce GT 310. (explain)
Pixel RateThe GeForce GTS 450 should be quite a bit (approximately 432%) better at FSAA than the GeForce GT 310, and also capable of handling higher screen resolutions more effectively. (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 largest amount of data (measured in megabytes per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 processed per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the 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 number of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
