Compare any two graphics cards:
GeForce GTX 285 1GB vs Radeon HD 4670 512MB
IntroThe GeForce GTX 285 1GB features a GPU clock speed of 648 MHz, and the 1024 MB of GDDR3 RAM is set to run at 1242 MHz through a 512-bit bus. It also is comprised of 240 Stream Processors, 80 Texture Address Units, and 32 ROPs.
Compare those specifications to the Radeon HD 4670 512MB, which comes with a GPU core clock speed of 750 MHz, and 512 MB of GDDR4/GDDR3/DDR3/DDR2 RAM running at 1000 MHz through a 128-bit bus. It also features 320(64x5) Stream Processors, 32 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 285 1GB should theoretically perform much faster than the Radeon HD 4670 512MB overall. (explain)
Texel RateThe GeForce GTX 285 1GB is a lot (more or less 116%) faster with regards to anisotropic filtering than the Radeon HD 4670 512MB. (explain)
Pixel RateThe GeForce GTX 285 1GB will be quite a bit (more or less 246%) faster with regards to full screen anti-aliasing than the Radeon HD 4670 512MB, and also should be capable of handling higher screen resolutions while still performing well. (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 largest amount of data (counted in megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster 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 can be processed in one second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
