Compare any two graphics cards:
GeForce GTX 260 Core 216 vs Radeon HD 7950
IntroThe GeForce GTX 260 Core 216 features a GPU core speed of 576 MHz, and the 896 MB of GDDR3 memory is set to run at 999 MHz through a 448-bit bus. It also features 216 SPUs, 72 Texture Address Units, and 28 ROPs.Compare all that to the Radeon HD 7950, which makes use of a 28 nm design. AMD has set the core speed at 800 MHz. The GDDR5 RAM is set to run at a speed of 1250 MHz on this particular model. It features 1792 SPUs as well as 112 Texture Address Units and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 7950 should in theory be much superior to the GeForce GTX 260 Core 216 overall. (explain)
Texel RateThe Radeon HD 7950 will be a lot (about 116%) faster with regards to anisotropic filtering than the GeForce GTX 260 Core 216. (explain)
Pixel RateThe Radeon HD 7950 is a lot (approximately 59%) more effective at anti-aliasing than the GeForce GTX 260 Core 216, and should be capable of handling higher screen 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: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 maximum number of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
