Compare any two graphics cards:
GeForce GTX 285 1GB vs Radeon R9 285
IntroThe GeForce GTX 285 1GB has a GPU clock speed of 648 MHz, and the 1024 MB of GDDR3 RAM runs at 1242 MHz through a 512-bit bus. It also is made up of 240 Stream Processors, 80 TAUs, and 32 Raster Operation Units.Compare those specifications to the Radeon R9 285, which uses a 28 nm design. AMD has set the core speed at 918 MHz. The GDDR5 RAM is set to run at a frequency of 1375 MHz on this particular model. It features 1792 SPUs as well as 112 TAUs and 32 Rasterization Operator Units.
Display Graphs
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R9 285 should theoretically perform a bit faster than the GeForce GTX 285 1GB overall. (explain)
Texel RateThe Radeon R9 285 should be quite a bit (more or less 98%) better at texture filtering than the GeForce GTX 285 1GB. (explain)
Pixel RateThe Radeon R9 285 should be a lot (more or less 42%) better at full screen anti-aliasing than the GeForce GTX 285 1GB, and should be able to handle higher resolutions while still performing well. (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 (in units of megabytes per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is worked out 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 per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
