Compare any two graphics cards:
GeForce 9500 GT 512MB GDDR3 vs Radeon HD 4670 512MB
IntroThe GeForce 9500 GT 512MB GDDR3 has core clock speeds of 550 MHz on the GPU, and 800 MHz on the 512 MB of GDDR3 RAM. It features 32 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.Compare all that to the Radeon HD 4670 512MB, which has core clock speeds of 750 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR4/GDDR3/DDR3/DDR2 memory. It features 320(64x5) SPUs as well as 32 Texture Address Units and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 4670 512MB is 25% faster than the GeForce 9500 GT 512MB GDDR3 in general, because of its greater data rate. (explain)
Texel RateThe Radeon HD 4670 512MB will be a lot (more or less 173%) better at texture filtering than the GeForce 9500 GT 512MB GDDR3. (explain)
Pixel RateThe Radeon HD 4670 512MB is quite a bit (about 36%) better at full screen anti-aliasing than the GeForce 9500 GT 512MB GDDR3, and will be able to handle higher screen resolutions more effectively. (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 data (counted in megabytes per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type 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 are processed in one second. This number is calculated by multiplying the total number of texture units by the core 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 maximum number of pixels the graphics card can 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 speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
