Compare any two graphics cards:
GeForce GTX 285 2GB vs Radeon R7 240
IntroThe GeForce GTX 285 2GB features core speeds of 648 MHz on the GPU, and 1242 MHz on the 2048 MB of GDDR3 RAM. It features 240 SPUs along with 80 Texture Address Units and 32 Rasterization Operator Units.Compare those specs to the Radeon R7 240, which has GPU core speed of 730 MHz, and 2048 MB of DDR3 RAM running at 900 MHz through a 128-bit bus. It also is made up of 320 SPUs, 20 TAUs, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 285 2GB should be 452% quicker than the Radeon R7 240 overall, because of its higher bandwidth. (explain)
Texel RateThe GeForce GTX 285 2GB will be quite a bit (more or less 255%) better at AF than the Radeon R7 240. (explain)
Pixel RateThe GeForce GTX 285 2GB should be a lot (about 255%) better at AA than the Radeon R7 240, and will be capable of handling 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 largest amount of data (measured in megabytes per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill 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 maximum fill rate.
