Compare any two graphics cards:
GeForce GTS 250 512MB vs Radeon HD 6570 (OEM) 1GB
IntroThe GeForce GTS 250 512MB makes use of a 65/55 nm design. nVidia has set the core speed at 738 MHz. The GDDR3 memory is set to run at a frequency of 1100 MHz on this specific card. It features 128 SPUs along with 64 Texture Address Units and 16 ROPs.
Compare all that to the Radeon HD 6570 (OEM) 1GB, which has core speeds of 650 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR3 memory. It features 480 SPUs along with 24 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GTS 250 512MB should in theory be quite a bit better than the Radeon HD 6570 (OEM) 1GB overall. (explain)
Texel RateThe GeForce GTS 250 512MB should be quite a bit (approximately 203%) better at AF than the Radeon HD 6570 (OEM) 1GB. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTS 250 512MB 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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the max amount of data (counted in megabytes per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 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 anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed 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 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 chip can possibly write to the local memory in one 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 sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
