Compare any two graphics cards:
GeForce 9800 GTX+ vs Radeon HD 4830 1GB
IntroThe GeForce 9800 GTX+ uses a 55 nm design. nVidia has clocked the core speed at 738 MHz. The GDDR3 RAM works at a frequency of 1100 MHz on this specific card. It features 128 SPUs as well as 64 TAUs and 16 ROPs.Compare those specs to the Radeon HD 4830 1GB, which features a GPU core clock speed of 575 MHz, and 1024 MB of GDDR4 RAM set to run at 900 MHz through a 256-bit bus. It also is made up of 640(128x5) Stream Processors, 32 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce 9800 GTX+ should perform much faster than the Radeon HD 4830 1GB overall. (explain)
Texel RateThe GeForce 9800 GTX+ will be quite a bit (approximately 157%) more effective at AF than the Radeon HD 4830 1GB. (explain)
Pixel RateThe GeForce 9800 GTX+ is a lot (more or less 28%) more effective at anti-aliasing than the Radeon HD 4830 1GB, and also will 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: Memory bandwidth is the max amount of information (measured in MB per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the 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 maximum amount of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). 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 potential to reach the maximum fill rate.
