Compare any two graphics cards:
GeForce 9800 GT 1GB vs Radeon HD 4730
IntroThe GeForce 9800 GT 1GB uses a 65/55 nm design. nVidia has set the core speed at 600 MHz. The GDDR3 RAM runs at a frequency of 900 MHz on this particular card. It features 112 SPUs along with 56 Texture Address Units and 16 ROPs.Compare all of that to the Radeon HD 4730, which uses a 55 nm design. AMD has clocked the core frequency at 700 MHz. The GDDR5 RAM works at a speed of 900 MHz on this particular card. It features 640(128x5) SPUs along with 32 TAUs and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have the exact same bandwidth, so in theory they should perform the same. (explain)
Texel RateThe GeForce 9800 GT 1GB will be a lot (more or less 50%) more effective at texture filtering than the Radeon HD 4730. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce 9800 GT 1GB 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 maximum amount of information (in units of megabytes per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
