Compare any two graphics cards:
GeForce GT 220 GDDR3 vs GeForce GT 230
IntroThe GeForce GT 220 GDDR3 has core clock speeds of 625 MHz on the GPU, and 1012 MHz on the 512 MB of GDDR3 RAM. It features 48 SPUs along with 16 Texture Address Units and 8 ROPs.Compare all of that to the GeForce GT 230, which features a clock frequency of 550 MHz and a DDR3 memory frequency of 800 MHz. It also uses a 192-bit bus, and uses a 40 nm design. It is comprised of 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GT 230 should be a little bit faster than the GeForce GT 220 GDDR3 in general. (explain)
Texel RateThe GeForce GT 220 GDDR3 will be a bit (more or less 14%) more effective at anisotropic filtering than the GeForce GT 230. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GT 220 GDDR3 is superior to the GeForce GT 230, but only just. (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 max amount of information (measured in MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is worked out 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 graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per 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. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
