Compare any two graphics cards:
GeForce GTS 250 1GB vs Radeon HD 5670
IntroThe GeForce GTS 250 1GB features core clock speeds of 738 MHz on the GPU, and 1100 MHz on the 1024 MB of GDDR3 RAM. It features 128 SPUs along with 64 TAUs and 16 ROPs.
Compare those specifications to the Radeon HD 5670, which has a GPU core clock speed of 775 MHz, and 1024 MB of GDDR5 memory running at 1000 MHz through a 128-bit bus. It also is made up of 400(80x5) Stream Processors, 20 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTS 250 1GB should theoretically be a small bit superior to the Radeon HD 5670 overall. (explain)
Texel RateThe GeForce GTS 250 1GB should be a lot (approximately 205%) better at anisotropic filtering than the Radeon HD 5670. (explain)
Pixel RateThe GeForce GTS 250 1GB should be much (approximately 90%) better at anti-aliasing than the Radeon HD 5670, and also will be capable of handling higher resolutions without slowing down too much. (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: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at 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 that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
