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 set the core frequency at 700 MHz. The GDDR3 memory is set to run at a frequency of 900 MHz on this specific card. It features 96 SPUs as well as 16 Texture Address Units and 4 Rasterization Operator Units.
Compare those specifications to the Radeon HD 5450, which comes with a GPU core clock speed of 650 MHz, and 512 MB of DDR3 memory running at 800 MHz through a 64-bit bus. It also features 80(16x5) Stream Processors, 8 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GT 430 1GB should in theory be much faster than the Radeon HD 5450 in general. (explain)
Texel RateThe GeForce GT 430 1GB is a lot (about 115%) more effective at texture filtering than the Radeon HD 5450. (explain)
Pixel RateThe GeForce GT 430 1GB should be a little bit (more or less 8%) faster with regards to FSAA than the Radeon HD 5450, and will be able to handle higher resolutions without losing too much performance. (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: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
