Compare any two graphics cards:
GeForce GTX 285 2GB vs Radeon R9 380X
IntroThe GeForce GTX 285 2GB makes use of a 55 nm design. nVidia has clocked the core frequency at 648 MHz. The GDDR3 memory is set to run at a speed of 1242 MHz on this card. It features 240 SPUs as well as 80 TAUs and 32 Rasterization Operator Units.Compare all that to the Radeon R9 380X, which comes with GPU core speed of 970 MHz, and 4096 MB of GDDR5 memory running at 1425 MHz through a 256-bit bus. It also is made up of 2048 Stream Processors, 128 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon R9 380X should in theory be a bit superior to the GeForce GTX 285 2GB overall. (explain)
Texel RateThe Radeon R9 380X should be quite a bit (more or less 140%) more effective at AF than the GeForce GTX 285 2GB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon R9 380X is a better choice, and very much so. (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 data (measured in MB per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number 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 output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
