Compare any two graphics cards:
GeForce 8800 GT 512MB vs Radeon R7 240
IntroThe GeForce 8800 GT 512MB makes use of a 65 nm design. nVidia has set the core frequency at 600 MHz. The GDDR3 memory runs at a frequency of 900 MHz on this particular model. It features 112 SPUs along with 56 TAUs and 16 Rasterization Operator Units.Compare that to the Radeon R7 240, which has a core clock speed of 730 MHz and a DDR3 memory frequency of 900 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It features 320 SPUs, 20 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce 8800 GT 512MB should in theory be a lot superior to the Radeon R7 240 in general. (explain)
Texel RateThe GeForce 8800 GT 512MB should be quite a bit (more or less 130%) better at AF than the Radeon R7 240. (explain)
Pixel RateThe GeForce 8800 GT 512MB is much (approximately 64%) more effective at AA than the Radeon R7 240, and also will be able to handle higher screen resolutions better. (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 max amount of data (counted in megabytes per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka 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 memory bandwidth is, the lower the ability to get to the maximum fill rate.
