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 clocked the core frequency at 700 MHz. The GDDR3 memory runs at a frequency of 900 MHz on this particular card. It features 96 SPUs as well as 16 Texture Address Units and 4 Rasterization Operator Units.
Compare all of that to the Radeon HD 5450, which comes with a clock frequency of 650 MHz and a DDR3 memory speed of 800 MHz. It also uses 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 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GT 430 1GB should be 125% faster than the Radeon HD 5450 overall, because of its greater data rate. (explain)
Texel RateThe GeForce GT 430 1GB should be a lot (approximately 115%) faster with regards to AF than the Radeon HD 5450. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GT 430 1GB is a better choice, though not 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 ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Bandwidth is the largest amount of information (counted in megabytes per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
