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

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GT 220 GDDR3 should theoretically be just a bit faster than the GeForce GT 430 overall. (explain)
Texel RateThe GeForce GT 430 will be a bit (about 12%) faster with regards to anisotropic filtering than the GeForce GT 220 GDDR3. (explain)
Pixel RateThe GeForce GT 220 GDDR3 should be a lot (more or less 79%) faster with regards to FSAA than the GeForce GT 430, and should be capable of handling higher screen 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 ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video 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 most pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
