Compare any two graphics cards:
GeForce GTS 250 512MB vs Radeon R9 285
IntroThe GeForce GTS 250 512MB comes with a clock speed of 738 MHz and a GDDR3 memory speed of 1100 MHz. It also features a 256-bit bus, and makes use of a 65/55 nm design. It features 128 SPUs, 64 TAUs, and 16 ROPs.Compare those specifications to the Radeon R9 285, which comes with a core clock frequency of 918 MHz and a GDDR5 memory speed of 1375 MHz. It also uses a 256-bit bus, and uses a 28 nm design. It is made up of 1792 SPUs, 112 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R9 285, in theory, should perform much faster than the GeForce GTS 250 512MB overall. (explain)
Texel RateThe Radeon R9 285 should be quite a bit (more or less 118%) better at AF than the GeForce GTS 250 512MB. (explain)
Pixel RateThe Radeon R9 285 is a lot (about 149%) better at full screen anti-aliasing than the GeForce GTS 250 512MB, and also will be able to handle higher screen 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 information (in units of megabytes per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, 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 number of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. 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 fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
