Compare any two graphics cards:
GeForce GT 430 (OEM) vs Radeon HD 6570 (OEM) 2GB
IntroThe GeForce GT 430 (OEM) makes use of a 40 nm design. nVidia has clocked the core speed at 700 MHz. The GDDR3 RAM is set to run at a frequency of 900 MHz on this particular model. It features 96 SPUs as well as 16 Texture Address Units and 4 Rasterization Operator Units.
Compare that to the Radeon HD 6570 (OEM) 2GB, which comes with core speeds of 650 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 RAM. It features 480 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the Radeon HD 6570 (OEM) 2GB is 122% quicker than the GeForce GT 430 (OEM) in general, due to its higher bandwidth. (explain)
Texel RateThe Radeon HD 6570 (OEM) 2GB should be quite a bit (approximately 39%) faster with regards to texture filtering than the GeForce GT 430 (OEM). (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon HD 6570 (OEM) 2GB is the winner, and very much so. (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 data (counted in megabytes per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If 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 number of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units by the core clock 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 most pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
