Compare any two graphics cards:
GeForce GT 430 vs Radeon HD 6570 (OEM) 1GB
IntroThe GeForce GT 430 comes with a core clock speed of 700 MHz and a GDDR3 memory frequency of 900 MHz. It also features a 128-bit bus, and uses a 40 nm design. It is comprised of 96 SPUs, 16 Texture Address Units, and 4 Raster Operation Units.
Compare all of that to the Radeon HD 6570 (OEM) 1GB, which has GPU clock speed of 650 MHz, and 1024 MB of GDDR3 memory running at 900 MHz through a 128-bit bus. It also is made up of 480 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Both cards have the exact same bandwidth, so theoretically they should have identical performance. (explain)
Texel RateThe Radeon HD 6570 (OEM) 1GB is much (more or less 39%) faster with regards to texture filtering than the GeForce GT 430. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon HD 6570 (OEM) 1GB 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: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the 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 number of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
