Compare any two graphics cards:
GeForce GT 315 vs Radeon R7 250X
IntroThe GeForce GT 315 comes with a clock speed of 625 MHz and a DDR3 memory frequency of 790 MHz. It also uses a 128-bit bus, and uses a 40 nm design. It is made up of 48 SPUs, 16 TAUs, and 8 Raster Operation Units.Compare those specifications to the Radeon R7 250X, which uses a 28 nm design. AMD has set the core frequency at 1000 MHz. The GDDR5 RAM is set to run at a speed of 1125 MHz on this specific model. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R7 250X should be a lot faster than the GeForce GT 315 overall. (explain)
Texel RateThe Radeon R7 250X will be quite a bit (approximately 300%) better at AF than the GeForce GT 315. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon R7 250X is a better choice, by a large margin. (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 (counted in megabytes per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number of 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 applied in a second. Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
