Compare any two graphics cards:
GeForce GT 130 vs Radeon HD 5450
IntroThe GeForce GT 130 uses a 55 nm design. nVidia has set the core speed at 500 MHz. The DDR2 RAM is set to run at a speed of 250 MHz on this model. It features 48 SPUs as well as 24 TAUs and 16 ROPs.Compare all of that to the Radeon HD 5450, which uses a 40 nm design. AMD has clocked the core frequency at 650 MHz. The DDR3 RAM runs at a speed of 800 MHz on this model. It features 80(16x5) SPUs as well as 8 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 5450 should theoretically perform just a bit faster than the GeForce GT 130 overall. (explain)
Texel RateThe GeForce GT 130 will be much (about 131%) faster with regards to texture filtering than the Radeon HD 5450. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GT 130 is superior to the Radeon HD 5450, 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 information (counted in MB per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 is worked out by multiplying the total texture units 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 most pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
