Compare any two graphics cards:
GeForce GT 430 1GB vs Radeon HD 5450
IntroThe GeForce GT 430 1GB makes use of a 40 nm design. nVidia has set the core frequency at 700 MHz. The GDDR3 RAM is set to run at a frequency of 900 MHz on this card. It features 96 SPUs as well as 16 Texture Address Units and 4 ROPs.
Compare those specs to the Radeon HD 5450, which comes with a clock frequency of 650 MHz and a DDR3 memory frequency of 800 MHz. It also features a 64-bit memory bus, and makes use of a 40 nm design. It is made up of 80(16x5) SPUs, 8 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GT 430 1GB should in theory be quite a bit superior to the Radeon HD 5450 overall. (explain)
Texel RateThe GeForce GT 430 1GB will be quite a bit (approximately 115%) faster with regards to AF than the Radeon HD 5450. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GT 430 1GB is superior to the Radeon HD 5450, but only just. (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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many 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.
