Compare any two graphics cards:
GeForce GT 220 GDDR3 vs Radeon HD 5830
IntroThe GeForce GT 220 GDDR3 has a clock speed of 625 MHz and a GDDR3 memory frequency of 1012 MHz. It also makes use of a 128-bit memory bus, and makes use of a 40 nm design. It is made up of 48 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.Compare those specifications to the Radeon HD 5830, which has a core clock speed of 800 MHz and a GDDR5 memory speed of 1000 MHz. It also makes use of a 256-bit memory bus, and makes use of a 40 nm design. It is comprised of 1120(224x5) SPUs, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 5830 should theoretically be quite a bit better than the GeForce GT 220 GDDR3 overall. (explain)
Texel RateThe Radeon HD 5830 should be a lot (more or less 348%) better at AF than the GeForce GT 220 GDDR3. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon HD 5830 is superior to the GeForce GT 220 GDDR3, and very much so. (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 maximum amount of information (in units of MB per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
