Compare any two graphics cards:
GeForce 8800 GT 512MB vs Radeon R9 M265X
IntroThe GeForce 8800 GT 512MB features core speeds of 600 MHz on the GPU, and 900 MHz on the 512 MB of GDDR3 RAM. It features 112 SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.Compare all of that to the Radeon R9 M265X, which comes with GPU clock speed of 575 MHz, and 2048 MB of GDDR5 RAM running at 1125 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 TAUs, and 16 ROPs.
Display Graphs
Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the Radeon R9 M265X will be 25% faster than the GeForce 8800 GT 512MB overall, due to its greater data rate. (explain)
Texel RateThe GeForce 8800 GT 512MB is quite a bit (approximately 46%) better at AF than the Radeon R9 M265X. (explain)
Pixel RateThe GeForce 8800 GT 512MB should be just a bit (approximately 4%) more effective at full screen anti-aliasing than the Radeon R9 M265X, 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 information (counted in MB per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, 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 maximum number of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core 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 output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
