Compare any two graphics cards:
Radeon HD 7950 3GB vs Radeon R7 250X 2GB
IntroThe Radeon HD 7950 3GB uses a 28 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 memory works at a frequency of 1250 MHz on this model. It features 1792 SPUs as well as 112 Texture Address Units and 32 Rasterization Operator Units.Compare all that to the Radeon R7 250X 2GB, which makes use of a 28 nm design. AMD has set the core speed at 1000 MHz. The GDDR5 RAM works at a speed of 1125 MHz on this card. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 7950 3GB should theoretically be much faster than the Radeon R7 250X 2GB overall. (explain)
Texel RateThe Radeon HD 7950 3GB should be quite a bit (more or less 124%) more effective at AF than the Radeon R7 250X 2GB. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon HD 7950 3GB is superior to the Radeon R7 250X 2GB, 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 MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's 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 number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better 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 maximum amount of pixels that the graphics card can possibly write to the local memory in a 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 filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
