Compare any two graphics cards:
GeForce GT 130 vs Radeon HD 5830
IntroThe GeForce GT 130 makes use of a 55 nm design. nVidia has set the core frequency at 500 MHz. The DDR2 RAM is set to run at a speed of 250 MHz on this specific card. It features 48 SPUs as well as 24 Texture Address Units and 16 Rasterization Operator Units.Compare those specifications to the Radeon HD 5830, which uses a 40 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 RAM works at a frequency of 1000 MHz on this particular card. It features 1120(224x5) SPUs along with 56 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 5830 should theoretically perform quite a bit faster than the GeForce GT 130 in general. (explain)
Texel RateThe Radeon HD 5830 is quite a bit (about 273%) faster with regards to AF than the GeForce GT 130. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon HD 5830 is superior to the GeForce GT 130, by far. (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 data (in units of MB per second) that can be transferred over the external memory interface in a 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, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes 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 - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
