Compare any two graphics cards:
GeForce 8800 GT 512MB vs Radeon R9 290
IntroThe GeForce 8800 GT 512MB uses a 65 nm design. nVidia has set the core speed at 600 MHz. The GDDR3 memory is set to run at a frequency of 900 MHz on this particular model. It features 112 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.Compare those specifications to the Radeon R9 290, which uses a 28 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 RAM is set to run at a speed of 1250 MHz on this specific card. It features 2560 SPUs along with 160 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon R9 290 should theoretically be much superior to the GeForce 8800 GT 512MB overall. (explain)
Texel RateThe Radeon R9 290 is a lot (about 281%) better at texture filtering than the GeForce 8800 GT 512MB. (explain)
Pixel RateThe Radeon R9 290 will be much (more or less 433%) faster with regards to FSAA than the GeForce 8800 GT 512MB, and also should be capable of handling 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: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
