Compare any two graphics cards:
GeForce 8800 GT 512MB vs Radeon HD 4670 1GB
IntroThe GeForce 8800 GT 512MB has a GPU clock speed of 600 MHz, and the 512 MB of GDDR3 RAM runs at 900 MHz through a 256-bit bus. It also is made up of 112 SPUs, 56 TAUs, and 16 Raster Operation Units.
Compare all of that to the Radeon HD 4670 1GB, which comes with core speeds of 750 MHz on the GPU, and 1100 MHz on the 1024 MB of GDDR4/GDDR3/DDR3/DDR2 memory. It features 320(64x5) SPUs along with 32 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce 8800 GT 512MB should be 64% quicker than the Radeon HD 4670 1GB overall, because of its greater bandwidth. (explain)
Texel RateThe GeForce 8800 GT 512MB should be much (more or less 40%) more effective at AF than the Radeon HD 4670 1GB. (explain)
Pixel RateThe GeForce 8800 GT 512MB should be a lot (more or less 60%) more effective at AA than the Radeon HD 4670 1GB, and 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.
Price ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Memory bandwidth is the max amount of data (measured in MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the graphics 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 the video card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
