Compare any two graphics cards:
GeForce GT 440 3GB vs Radeon HD 4670 1GB
IntroThe GeForce GT 440 3GB comes with a core clock frequency of 594 MHz and a GDDR3 memory speed of 900 MHz. It also features a 192-bit bus, and uses a 40 nm design. It is made up of 144 SPUs, 24 TAUs, and 24 ROPs.Compare those specs to the Radeon HD 4670 1GB, which has GPU clock speed of 750 MHz, and 1024 MB of GDDR4/GDDR3/DDR3/DDR2 memory running at 1100 MHz through a 128-bit bus. It also features 320(64x5) Stream Processors, 32 TAUs, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GT 440 3GB should be 23% faster than the Radeon HD 4670 1GB in general, due to its greater data rate. (explain)
Texel RateThe Radeon HD 4670 1GB will be much (about 68%) more effective at AF than the GeForce GT 440 3GB. (explain)
Pixel RateThe GeForce GT 440 3GB is a lot (about 138%) more effective at full screen anti-aliasing than the Radeon HD 4670 1GB, and also should be capable of handling higher 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 Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
