Compare any two graphics cards:
GeForce GT 230 vs GeForce GT 440 3GB
IntroThe GeForce GT 230 has a GPU core clock speed of 550 MHz, and the 1536 MB of DDR3 RAM is set to run at 800 MHz through a 192-bit bus. It also is comprised of 32 SPUs, 16 TAUs, and 8 Raster Operation Units.Compare those specs to the GeForce GT 440 3GB, which has core speeds of 594 MHz on the GPU, and 900 MHz on the 3072 MB of GDDR3 RAM. It features 144 SPUs as well as 24 TAUs and 24 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GT 440 3GB should theoretically be a small bit faster than the GeForce GT 230 in general. (explain)
Texel RateThe GeForce GT 440 3GB is a lot (about 62%) faster with regards to AF than the GeForce GT 230. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GT 440 3GB is a better choice, 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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total amount of texture units 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 in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
