Compare any two graphics cards:
GeForce 9800 GTX+ vs Radeon HD 4850 1GB
IntroThe GeForce 9800 GTX+ features a clock speed of 738 MHz and a GDDR3 memory speed of 1100 MHz. It also uses a 256-bit bus, and uses a 55 nm design. It features 128 SPUs, 64 Texture Address Units, and 16 ROPs.Compare those specs to the Radeon HD 4850 1GB, which comes with a GPU core clock speed of 625 MHz, and 1024 MB of GDDR4 RAM running at 993 MHz through a 256-bit bus. It also features 800(160x5) SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce 9800 GTX+ should theoretically be a bit superior to the Radeon HD 4850 1GB overall. (explain)
Texel RateThe GeForce 9800 GTX+ should be much (about 89%) faster with regards to texture filtering than the Radeon HD 4850 1GB. (explain)
Pixel RateThe GeForce 9800 GTX+ should be a small bit (more or less 18%) better at AA than the Radeon HD 4850 1GB, and should be able to handle higher 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 maximum amount of data (measured in megabytes per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour 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 also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
