Compare any two graphics cards:
GeForce GT 430 1GB vs Radeon HD 5450
IntroThe GeForce GT 430 1GB uses a 40 nm design. nVidia has clocked the core frequency at 700 MHz. The GDDR3 memory runs at a frequency of 900 MHz on this card. It features 96 SPUs as well as 16 TAUs and 4 Rasterization Operator Units.
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 memory works at a frequency of 800 MHz on this particular card. It features 80(16x5) SPUs as well as 8 Texture Address Units and 4 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GT 430 1GB is 125% faster than the Radeon HD 5450 in general, because of its greater data rate. (explain)
Texel RateThe GeForce GT 430 1GB should be a lot (approximately 115%) more effective at anisotropic filtering than the Radeon HD 5450. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GT 430 1GB is a better choice, 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 maximum amount of information (counted in MB per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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 - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
