Compare any two graphics cards:
Radeon HD 7950 vs Radeon R7 250
IntroThe Radeon HD 7950 uses a 28 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 memory works at a speed of 1250 MHz on this particular model. It features 1792 SPUs along with 112 TAUs and 32 Rasterization Operator Units.Compare that to the Radeon R7 250, which comes with core speeds of 1000 MHz on the GPU, and 1150 MHz on the 1024 MB of GDDR5 RAM. It features 384 SPUs as well as 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 7950, in theory, should perform a lot faster than the Radeon R7 250 overall. (explain)
Texel RateThe Radeon HD 7950 is a lot (approximately 273%) better at AF than the Radeon R7 250. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon HD 7950 is the winner, and very much so. (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 information (counted in megabytes per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher 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 texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total amount 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 in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
