Compare any two graphics cards:
GeForce GT 220 GDDR3 vs GeForce GT 430
IntroThe GeForce GT 220 GDDR3 has a GPU core speed of 625 MHz, and the 512 MB of GDDR3 memory is set to run at 1012 MHz through a 128-bit bus. It also is made up of 48 Stream Processors, 16 Texture Address Units, and 8 ROPs.
Compare all that to the GeForce GT 430, which makes use of a 40 nm design. nVidia has clocked the core frequency at 700 MHz. The GDDR3 RAM is set to run at a frequency of 900 MHz on this model. It features 96 SPUs along with 16 Texture Address Units and 4 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GT 220 GDDR3 should in theory perform a bit faster than the GeForce GT 430 in general. (explain)
Texel RateThe GeForce GT 430 will be a little bit (more or less 12%) faster with regards to texture filtering than the GeForce GT 220 GDDR3. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GT 220 GDDR3 is the winner, by far. (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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the maximum 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 card's interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output 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 reach the maximum fill rate.
