Compare any two graphics cards:
GeForce GTX 260 Core 216 vs Radeon HD 6950
IntroThe GeForce GTX 260 Core 216 has a core clock frequency of 576 MHz and a GDDR3 memory speed of 999 MHz. It also features a 448-bit bus, and makes use of a 65 nm design. It is made up of 216 SPUs, 72 TAUs, and 28 ROPs.Compare those specifications to the Radeon HD 6950, which makes use of a 40 nm design. AMD has set the core speed at 800 MHz. The GDDR5 memory runs at a frequency of 1250 MHz on this specific card. It features 1408 SPUs as well as 88 TAUs and 32 ROPs.
Display Graphs
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 6950 is 43% quicker than the GeForce GTX 260 Core 216 overall, because of its higher bandwidth. (explain)
Texel RateThe Radeon HD 6950 should be a lot (approximately 70%) more effective at AF than the GeForce GTX 260 Core 216. (explain)
Pixel RateThe Radeon HD 6950 is much (more or less 59%) faster with regards to FSAA than the GeForce GTX 260 Core 216, and also should be able to handle higher resolutions without losing too much performance. (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 information (measured in megabytes per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 texture map elements (texels) that are processed in one second. This is calculated by multiplying the total 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
