Compare any two graphics cards:
GeForce GTS 250 512MB vs Radeon HD 6570 (OEM) 1GB
IntroThe GeForce GTS 250 512MB comes with a clock frequency of 738 MHz and a GDDR3 memory speed of 1100 MHz. It also features a 256-bit bus, and makes use of a 65/55 nm design. It is comprised of 128 SPUs, 64 TAUs, and 16 Raster Operation Units.
Compare those specs to the Radeon HD 6570 (OEM) 1GB, which uses a 40 nm design. AMD has set the core frequency at 650 MHz. The GDDR3 memory is set to run at a frequency of 900 MHz on this model. It features 480 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTS 250 512MB is 144% quicker than the Radeon HD 6570 (OEM) 1GB in general, because of its higher bandwidth. (explain)
Texel RateThe GeForce GTS 250 512MB is quite a bit (more or less 203%) faster with regards to anisotropic filtering than the Radeon HD 6570 (OEM) 1GB. (explain)
Pixel RateIf running with high levels of AA 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 maximum amount of information (counted in MB per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better 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 amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write 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 core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
