Compare any two graphics cards:
GeForce GT 430 vs Radeon HD 4670 1GB
IntroThe GeForce GT 430 features a clock speed of 700 MHz and a GDDR3 memory speed of 900 MHz. It also uses a 128-bit bus, and uses a 40 nm design. It is made up of 96 SPUs, 16 Texture Address Units, and 4 Raster Operation Units.Compare those specs to the Radeon HD 4670 1GB, which uses a 55 nm design. AMD has set the core frequency at 750 MHz. The GDDR4/GDDR3/DDR3/DDR2 RAM is set to run at a speed of 1100 MHz on this model. It features 320(64x5) SPUs along with 32 Texture Address Units and 8 ROPs.
Display Graphs
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 4670 1GB should be 22% faster than the GeForce GT 430 overall, due to its greater data rate. (explain)
Texel RateThe Radeon HD 4670 1GB is quite a bit (more or less 114%) faster with regards to AF than the GeForce GT 430. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon HD 4670 1GB is a better choice, 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 maximum amount of data (counted in MB per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
