Compare any two graphics cards:
GeForce 8800 GT 512MB vs Radeon R7 250
IntroThe GeForce 8800 GT 512MB has clock speeds of 600 MHz on the GPU, and 900 MHz on the 512 MB of GDDR3 memory. It features 112 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.Compare those specifications to the Radeon R7 250, which has core speeds of 1000 MHz on the GPU, and 1150 MHz on the 1024 MB of GDDR5 RAM. It features 384 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R7 250, in theory, should perform a lot faster than the GeForce 8800 GT 512MB in general. (explain)
Texel RateThe GeForce 8800 GT 512MB will be quite a bit (more or less 40%) better at AF than the Radeon R7 250. (explain)
Pixel RateThe GeForce 8800 GT 512MB is just a bit (approximately 20%) better at anti-aliasing than the Radeon R7 250, and will be capable of handling higher resolutions more effectively. (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 (counted in megabytes per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the 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 amount of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
