Compare any two graphics cards:
GeForce GT 315 vs Radeon R7 240
IntroThe GeForce GT 315 has a GPU core speed of 625 MHz, and the 512 MB of DDR3 RAM runs at 790 MHz through a 128-bit bus. It also is made up of 48 Stream Processors, 16 Texture Address Units, and 8 Raster Operation Units.Compare those specifications to the Radeon R7 240, which has core speeds of 730 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 RAM. It features 320 SPUs along with 20 TAUs and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon R7 240 should theoretically be a small bit better than the GeForce GT 315 overall. (explain)
Texel RateThe Radeon R7 240 will be much (approximately 46%) faster with regards to anisotropic filtering than the GeForce GT 315. (explain)
Pixel RateThe Radeon R7 240 will be a small bit (about 17%) faster with regards to full screen anti-aliasing than the GeForce GT 315, and able to handle higher resolutions better. (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 transferred over the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster 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 processed in one second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on 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 reach the maximum fill rate.
