Compare any two graphics cards:
GeForce GTX 285 1GB vs Radeon HD 4670 512MB
IntroThe GeForce GTX 285 1GB has a clock speed of 648 MHz and a GDDR3 memory speed of 1242 MHz. It also uses a 512-bit bus, and uses a 55 nm design. It features 240 SPUs, 80 TAUs, and 32 Raster Operation Units.
Compare those specifications to the Radeon HD 4670 512MB, which comes with a clock frequency of 750 MHz and a GDDR4/GDDR3/DDR3/DDR2 memory frequency of 1000 MHz. It also makes use of a 128-bit memory bus, and makes use of a 55 nm design. It features 320(64x5) SPUs, 32 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 285 1GB should theoretically perform a lot faster than the Radeon HD 4670 512MB in general. (explain)
Texel RateThe GeForce GTX 285 1GB will be quite a bit (more or less 116%) more effective at texture filtering than the Radeon HD 4670 512MB. (explain)
Pixel RateThe GeForce GTX 285 1GB will be quite a bit (about 246%) better at anti-aliasing than the Radeon HD 4670 512MB, and will be able to handle higher screen resolutions without losing too much performance. (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 largest amount of data (measured in megabytes per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 are processed in one second. This figure is worked out by multiplying the total number of texture units by the core clock 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 in one second.
Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount 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 rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
