Compare any two graphics cards:
GeForce 8400 GS 512MB vs Radeon R7 250X 2GB
IntroThe GeForce 8400 GS 512MB makes use of a 80 nm design. nVidia has clocked the core speed at 650 MHz. The DDR2 RAM runs at a speed of 400 MHz on this particular model. It features 16 SPUs as well as 8 Texture Address Units and 4 ROPs.Compare those specs to the Radeon R7 250X 2GB, which comes with a clock speed of 1000 MHz and a GDDR5 memory speed of 1125 MHz. It also features a 128-bit bus, and makes use of a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon R7 250X 2GB will be 1025% faster than the GeForce 8400 GS 512MB overall, because of its higher bandwidth. (explain)
Texel RateThe Radeon R7 250X 2GB should be quite a bit (more or less 669%) faster with regards to AF than the GeForce 8400 GS 512MB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon R7 250X 2GB is the winner, 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 (in units of megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the 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 number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
