Compare any two graphics cards:
GeForce 9800 GT 1GB vs Radeon HD 6570 (OEM) 2GB
IntroThe GeForce 9800 GT 1GB makes use of a 65/55 nm design. nVidia has set the core frequency at 600 MHz. The GDDR3 RAM runs at a frequency of 900 MHz on this model. It features 112 SPUs as well as 56 Texture Address Units and 16 ROPs.Compare those specs to the Radeon HD 6570 (OEM) 2GB, which features a clock speed of 650 MHz and a GDDR5 memory frequency of 1000 MHz. It also features a 128-bit memory bus, and makes use of a 40 nm design. It is made up of 480 SPUs, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 6570 (OEM) 2GB should be 11% faster than the GeForce 9800 GT 1GB in general, because of its greater bandwidth. (explain)
Texel RateThe GeForce 9800 GT 1GB will be quite a bit (more or less 115%) better at anisotropic filtering than the Radeon HD 6570 (OEM) 2GB. (explain)
Pixel RateThe GeForce 9800 GT 1GB will be quite a bit (approximately 85%) faster with regards to FSAA than the Radeon HD 6570 (OEM) 2GB, and will be capable of handling higher screen resolutions while still performing well. (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 largest amount of information (counted in MB per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can 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 Raster Operations Pipelines by the clock speed of the card. 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 fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
