Compare any two graphics cards:
GeForce GT 320 vs GeForce GTX 280
IntroThe GeForce GT 320 comes with core speeds of 540 MHz on the GPU, and 790 MHz on the 1024 MB of GDDR3 memory. It features 72 SPUs along with 24 TAUs and 8 ROPs.Compare that to the GeForce GTX 280, which uses a 65 nm design. nVidia has clocked the core frequency at 602 MHz. The GDDR3 memory is set to run at a speed of 1107 MHz on this particular model. It features 240 SPUs along with 80 Texture Address Units and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 280, in theory, should be quite a bit faster than the GeForce GT 320 in general. (explain)
Texel RateThe GeForce GTX 280 will be much (about 272%) better at anisotropic filtering than the GeForce GT 320. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GTX 280 is the winner, by a large margin. (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 maximum amount of data (measured in MB per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core speed of the card. 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, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
