Compare any two graphics cards:
GeForce GTX 470 vs Radeon HD 4670 1GB
IntroThe GeForce GTX 470 features a clock speed of 607 MHz and a GDDR5 memory frequency of 837 MHz. It also makes use of a 320-bit memory bus, and makes use of a 40 nm design. It is comprised of 448 SPUs, 56 Texture Address Units, and 40 ROPs.Compare those specifications to the Radeon HD 4670 1GB, which comes with a core clock speed of 750 MHz and a GDDR4/GDDR3/DDR3/DDR2 memory speed of 1100 MHz. It also makes use of a 128-bit bus, and uses 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 theoretically be much better than the Radeon HD 4670 1GB overall. (explain)
Texel RateThe GeForce GTX 470 will be a lot (more or less 42%) better at AF than the Radeon HD 4670 1GB. (explain)
Pixel RateThe GeForce GTX 470 is much (approximately 305%) better at anti-aliasing than the Radeon HD 4670 1GB, and will be able to handle 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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total texture units of the card 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 in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
