Compare any two graphics cards:
GeForce GTX 470 vs Radeon HD 4670 512MB
IntroThe GeForce GTX 470 comes with a GPU core clock speed of 607 MHz, and the 1280 MB of GDDR5 memory runs at 837 MHz through a 320-bit bus. It also is comprised of 448 Stream Processors, 56 Texture Address Units, and 40 Raster Operation Units.Compare those specs to the Radeon HD 4670 512MB, which features a clock speed of 750 MHz and a GDDR4/GDDR3/DDR3/DDR2 memory frequency of 1000 MHz. It also uses a 128-bit memory bus, and makes use of a 55 nm design. It is comprised of 320(64x5) SPUs, 32 TAUs, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 470 should in theory be a lot superior to the Radeon HD 4670 512MB in general. (explain)
Texel RateThe GeForce GTX 470 should be much (approximately 42%) faster with regards to anisotropic filtering than the Radeon HD 4670 512MB. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GTX 470 is the winner, and very much so. (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 Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the max amount of data (in units of megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
