Compare any two graphics cards:
GeForce GTX 285 1GB vs Radeon HD 4670 512MB
IntroThe GeForce GTX 285 1GB uses a 55 nm design. nVidia has clocked the core speed at 648 MHz. The GDDR3 memory is set to run at a frequency of 1242 MHz on this particular model. It features 240 SPUs along with 80 Texture Address Units and 32 Rasterization Operator Units.
Compare that to the Radeon HD 4670 512MB, which makes use of a 55 nm design. AMD has clocked the core frequency at 750 MHz. The GDDR4/GDDR3/DDR3/DDR2 RAM works at a frequency of 1000 MHz on this model. It features 320(64x5) SPUs as well as 32 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 285 1GB should theoretically be a lot better than the Radeon HD 4670 512MB overall. (explain)
Texel RateThe GeForce GTX 285 1GB will be a lot (approximately 116%) better at anisotropic filtering than the Radeon HD 4670 512MB. (explain)
Pixel RateThe GeForce GTX 285 1GB will be much (about 246%) faster with regards to anti-aliasing than the Radeon HD 4670 512MB, and also will be able to handle higher 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 information (in units of megabytes per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum amount of 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 amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). 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 potential to reach the maximum fill rate.
