Compare any two graphics cards:
GeForce GTS 250 512MB vs Radeon HD 6570 (OEM) 1GB
IntroThe GeForce GTS 250 512MB comes with core speeds of 738 MHz on the GPU, and 1100 MHz on the 512 MB of GDDR3 RAM. It features 128 SPUs as well as 64 TAUs and 16 Rasterization Operator Units.
Compare those specs to the Radeon HD 6570 (OEM) 1GB, which features GPU core 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)
Theoretically speaking, the GeForce GTS 250 512MB should be 144% faster than the Radeon HD 6570 (OEM) 1GB overall, because of its higher bandwidth. (explain)
Texel RateThe GeForce GTS 250 512MB should be a lot (approximately 203%) more effective at anisotropic filtering than the Radeon HD 6570 (OEM) 1GB. (explain)
Pixel RateThe GeForce GTS 250 512MB will be a lot (more or less 127%) faster with regards to FSAA than the Radeon HD 6570 (OEM) 1GB, and also will be able to handle higher resolutions while still performing well. (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 (measured in megabytes per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
