Compare any two graphics cards:
GeForce GT 320 vs Geforce GTX 670
IntroThe GeForce GT 320 features a GPU core speed of 540 MHz, and the 1024 MB of GDDR3 memory runs at 790 MHz through a 128-bit bus. It also is made up of 72 SPUs, 24 TAUs, and 8 Raster Operation Units.Compare all of that to the Geforce GTX 670, which comes with GPU core speed of 915 MHz, and 2048 MB of GDDR5 RAM running at 1500 MHz through a 256-bit bus. It also features 1344 SPUs, 112 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Geforce GTX 670 should perform much faster than the GeForce GT 320 in general. (explain)
Texel RateThe Geforce GTX 670 is much (approximately 691%) more effective at texture filtering than the GeForce GT 320. (explain)
Pixel RateThe Geforce GTX 670 will be much (about 578%) more effective at FSAA than the GeForce GT 320, and should be able to handle higher 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 maximum amount of data (in units of MB per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
