Compare any two graphics cards:
GeForce GT 430 1GB vs Radeon HD 6950 2GB
IntroThe GeForce GT 430 1GB has a core clock frequency of 700 MHz and a GDDR3 memory frequency of 900 MHz. It also features a 128-bit memory bus, and makes use of a 40 nm design. It is comprised of 96 SPUs, 16 TAUs, and 4 ROPs.Compare all of that to the Radeon HD 6950 2GB, which comes with clock speeds of 800 MHz on the GPU, and 1250 MHz on the 2048 MB of GDDR5 RAM. It features 1408 SPUs as well as 88 Texture Address Units and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 6950 2GB should perform a lot faster than the GeForce GT 430 1GB in general. (explain)
Texel RateThe Radeon HD 6950 2GB should be quite a bit (about 529%) faster with regards to texture filtering than the GeForce GT 430 1GB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon HD 6950 2GB 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 maximum amount of data (measured in MB per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the 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 clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
