Compare any two graphics cards:
GeForce GT 430 (OEM) vs Radeon HD 4670 512MB
IntroThe GeForce GT 430 (OEM) features a clock frequency of 700 MHz and a GDDR3 memory speed of 900 MHz. It also features a 128-bit memory bus, and uses a 40 nm design. It is comprised of 96 SPUs, 16 TAUs, and 4 Raster Operation Units.Compare those specifications to the Radeon HD 4670 512MB, which features a clock frequency of 750 MHz and a GDDR4/GDDR3/DDR3/DDR2 memory frequency of 1000 MHz. It also makes use of a 128-bit memory bus, and makes use of a 55 nm design. It features 320(64x5) SPUs, 32 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 4670 512MB should theoretically be a little bit faster than the GeForce GT 430 (OEM) in general. (explain)
Texel RateThe Radeon HD 4670 512MB should be a lot (approximately 114%) better at AF than the GeForce GT 430 (OEM). (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon HD 4670 512MB is a better choice, by far. (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: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core 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 rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
