Compare any two graphics cards:
GeForce GTX 285 2GB vs Radeon R7 240
IntroThe GeForce GTX 285 2GB features a GPU core clock speed of 648 MHz, and the 2048 MB of GDDR3 memory runs at 1242 MHz through a 512-bit bus. It also is made up of 240 Stream Processors, 80 Texture Address Units, and 32 ROPs.Compare those specs to the Radeon R7 240, which uses a 28 nm design. AMD has clocked the core speed at 730 MHz. The DDR3 RAM works at a speed of 900 MHz on this model. It features 320 SPUs along with 20 Texture Address Units and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 285 2GB should be much faster than the Radeon R7 240 overall. (explain)
Texel RateThe GeForce GTX 285 2GB will be quite a bit (more or less 255%) better at anisotropic filtering than the Radeon R7 240. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 285 2GB is a better choice, by far. (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 maximum amount of data (measured in megabytes per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units of the card by the core 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 in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel 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.
