Compare any two graphics cards:
GeForce GTX 260 Core 216 vs Radeon HD 6450 (OEM) 1GB
IntroThe GeForce GTX 260 Core 216 uses a 65 nm design. nVidia has clocked the core speed at 576 MHz. The GDDR3 RAM runs at a frequency of 999 MHz on this card. It features 216 SPUs as well as 72 Texture Address Units and 28 Rasterization Operator Units.
Compare those specifications to the Radeon HD 6450 (OEM) 1GB, which comes with a clock frequency of 750 MHz and a GDDR5 memory speed of 900 MHz. It also features a 64-bit bus, and makes use of a 40 nm design. It is made up of 160 SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 260 Core 216 should theoretically perform a lot faster than the Radeon HD 6450 (OEM) 1GB in general. (explain)
Texel RateThe GeForce GTX 260 Core 216 should be much (more or less 591%) faster with regards to AF than the Radeon HD 6450 (OEM) 1GB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 260 Core 216 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 largest amount of data (in units of megabytes per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units of the card 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 processed in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
