Compare any two graphics cards:
GeForce GTX 260 vs Radeon HD 6450 (OEM)
IntroThe GeForce GTX 260 uses a 65 nm design. nVidia has clocked the core frequency at 576 MHz. The GDDR3 memory runs at a speed of 999 MHz on this particular model. It features 192 SPUs as well as 64 TAUs and 28 ROPs.
Compare those specifications to the Radeon HD 6450 (OEM), which makes use of a 40 nm design. ATi has clocked the core frequency at 625 MHz. The GDDR3 memory works at a frequency of 800 MHz on this 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)
In theory, the GeForce GTX 260 is 774% quicker than the Radeon HD 6450 (OEM) overall, because of its greater bandwidth. (explain)
Texel RateThe GeForce GTX 260 is a lot (approximately 637%) more effective at anisotropic filtering than the Radeon HD 6450 (OEM). (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GTX 260 is a better choice, 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 max amount of information (counted in MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher 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 in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
