Compare any two graphics cards:
GeForce GT 220 GDDR3 vs GeForce GT 430 1GB
IntroThe GeForce GT 220 GDDR3 features core speeds of 625 MHz on the GPU, and 1012 MHz on the 512 MB of GDDR3 memory. It features 48 SPUs as well as 16 Texture Address Units and 8 ROPs.Compare those specifications to the GeForce GT 430 1GB, which makes use of a 40 nm design. nVidia has set the core speed at 700 MHz. The GDDR3 RAM runs at a speed of 900 MHz on this specific model. It features 96 SPUs as well as 16 Texture Address Units and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GT 220 GDDR3 should be a bit faster than the GeForce GT 430 1GB overall. (explain)
Texel RateThe GeForce GT 430 1GB should be just a bit (more or less 12%) more effective at anisotropic filtering than the GeForce GT 220 GDDR3. (explain)
Pixel RateThe GeForce GT 220 GDDR3 should be much (more or less 79%) faster with regards to AA than the GeForce GT 430 1GB, and should be able to handle higher 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 maximum amount of data (measured in MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, 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 figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called 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 ability to get to the maximum fill rate.
