Compare any two graphics cards:
GeForce GT 240 GDDR5 vs Radeon R7 250
IntroThe GeForce GT 240 GDDR5 has a GPU core speed of 550 MHz, and the 512 MB of GDDR5 RAM is set to run at 850 MHz through a 128-bit bus. It also is comprised of 96 SPUs, 32 TAUs, and 8 Raster Operation Units.Compare all that to the Radeon R7 250, which features a clock frequency of 1000 MHz and a GDDR5 memory frequency of 1150 MHz. It also features a 128-bit bus, and uses a 28 nm design. It is made up of 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R7 250 should be 35% quicker than the GeForce GT 240 GDDR5 overall, due to its higher bandwidth. (explain)
Texel RateThe Radeon R7 250 should be quite a bit (about 36%) faster with regards to texture filtering than the GeForce GT 240 GDDR5. (explain)
Pixel RateThe Radeon R7 250 should be a lot (about 82%) faster with regards to AA than the GeForce GT 240 GDDR5, and also should be capable of handling higher resolutions without losing too much performance. (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 largest amount of data (in units of megabytes per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units by the core clock 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 applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
