Compare any two graphics cards:
GeForce GT 440 1.5GB vs Radeon HD 5750 1GB
IntroThe GeForce GT 440 1.5GB makes use of a 40 nm design. nVidia has clocked the core frequency at 594 MHz. The GDDR3 RAM runs at a frequency of 900 MHz on this particular model. It features 144 SPUs as well as 24 TAUs and 24 ROPs.Compare those specifications to the Radeon HD 5750 1GB, which features GPU clock speed of 700 MHz, and 1024 MB of GDDR5 memory running at 1150 MHz through a 128-bit bus. It also is comprised of 720(144x5) SPUs, 36 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon HD 5750 1GB should perform much faster than the GeForce GT 440 1.5GB overall. (explain)
Texel RateThe Radeon HD 5750 1GB should be much (approximately 77%) faster with regards to texture filtering than the GeForce GT 440 1.5GB. (explain)
Pixel RateThe GeForce GT 440 1.5GB should be a lot (more or less 27%) more effective at anti-aliasing than the Radeon HD 5750 1GB, and able to handle higher screen resolutions without losing too much performance. (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 max amount of information (counted in MB per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is calculated 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 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 card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock 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 output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
