Compare any two graphics cards:
GeForce GTX 560 vs Radeon HD 6450 (OEM) 1GB
IntroThe GeForce GTX 560 uses a 40 nm design. nVidia has set the core frequency at 810 MHz. The GDDR5 RAM works at a frequency of 1001 MHz on this card. It features 336 SPUs as well as 56 TAUs and 32 Rasterization Operator Units.
Compare those specifications to the Radeon HD 6450 (OEM) 1GB, which makes use of a 40 nm design. ATi has clocked the core speed at 750 MHz. The GDDR5 memory is set to run at a frequency of 900 MHz on this specific card. It features 160 SPUs as well as 8 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the GeForce GTX 560 should be much faster than the Radeon HD 6450 (OEM) 1GB in general. (explain)
Texel RateThe GeForce GTX 560 is quite a bit (more or less 656%) more effective at AF than the Radeon HD 6450 (OEM) 1GB. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTX 560 is a better choice, by a large margin. (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 maximum amount of information (in units of megabytes per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
