Compare any two graphics cards:
GeForce GT 230 vs GeForce GT 440 3GB
IntroThe GeForce GT 230 has a GPU clock speed of 550 MHz, and the 1536 MB of DDR3 RAM runs at 800 MHz through a 192-bit bus. It also features 32 Stream Processors, 16 TAUs, and 8 ROPs.Compare all of that to the GeForce GT 440 3GB, which comes with a clock speed of 594 MHz and a GDDR3 memory frequency of 900 MHz. It also makes use of a 192-bit bus, and makes use of a 40 nm design. It is made up of 144 SPUs, 24 TAUs, and 24 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GT 440 3GB should perform a little bit faster than the GeForce GT 230 overall. (explain)
Texel RateThe GeForce GT 440 3GB should be quite a bit (approximately 62%) better at anisotropic filtering 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 a large margin. (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: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
