Compare any two graphics cards:
GeForce 8600 GT 512MB GDDR3 vs Radeon R9 270X
IntroThe GeForce 8600 GT 512MB GDDR3 uses a 80 nm design. nVidia has set the core frequency at 540 MHz. The GDDR3 memory is set to run at a speed of 700 MHz on this specific model. It features 32 SPUs as well as 16 Texture Address Units and 8 ROPs.Compare those specifications to the Radeon R9 270X, which uses a 28 nm design. AMD has clocked the core speed at 1000 MHz. The GDDR5 RAM works at a frequency of 1400 MHz on this card. It features 1280 SPUs as well as 80 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R9 270X should perform much faster than the GeForce 8600 GT 512MB GDDR3 in general. (explain)
Texel RateThe Radeon R9 270X is much (about 826%) faster with regards to AF than the GeForce 8600 GT 512MB GDDR3. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon R9 270X is a better choice, by a large margin. (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 max amount of information (in units of megabytes per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. If it uses 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 faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
