Compare any two graphics cards:
Radeon HD 7950 3GB vs Radeon R9 390 8G
IntroThe Radeon HD 7950 3GB comes with a GPU clock speed of 800 MHz, and the 3072 MB of GDDR5 RAM runs at 1250 MHz through a 384-bit bus. It also features 1792 SPUs, 112 TAUs, and 32 Raster Operation Units.Compare that to the Radeon R9 390 8G, which makes use of a 28 nm design. AMD has clocked the core frequency at 1000 MHz. The GDDR5 RAM is set to run at a speed of 1500 MHz on this particular model. It features 2560 SPUs as well as 160 TAUs and 64 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon R9 390 8G should perform much faster than the Radeon HD 7950 3GB overall. (explain)
Texel RateThe Radeon R9 390 8G is a lot (about 79%) better at texture filtering than the Radeon HD 7950 3GB. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon R9 390 8G 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: Bandwidth is the maximum amount of information (in units of MB per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock 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 number of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
