Compare any two graphics cards:
GeForce 9800 GTX+ vs Radeon HD 4850 2GB
IntroThe GeForce 9800 GTX+ makes use of a 55 nm design. nVidia has set the core frequency at 738 MHz. The GDDR3 memory runs at a speed of 1100 MHz on this model. It features 128 SPUs along with 64 TAUs and 16 ROPs.Compare all that to the Radeon HD 4850 2GB, which comes with clock speeds of 625 MHz on the GPU, and 993 MHz on the 2048 MB of GDDR4 memory. It features 800(160x5) SPUs as well as 40 TAUs 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 little bit superior to the Radeon HD 4850 2GB in general. (explain)
Texel RateThe GeForce 9800 GTX+ is much (about 89%) faster with regards to texture filtering than the Radeon HD 4850 2GB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce 9800 GTX+ is superior to the Radeon HD 4850 2GB, but it probably won't make a huge difference. (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 largest amount of data (in units of megabytes per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units 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 output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
