Compare any two graphics cards:
Radeon HD 7950 3GB vs Radeon R9 M295X
IntroThe Radeon HD 7950 3GB has a clock frequency of 800 MHz and a GDDR5 memory frequency of 1250 MHz. It also uses a 384-bit bus, and makes use of a 28 nm design. It is made up of 1792 SPUs, 112 Texture Address Units, and 32 Raster Operation Units.Compare all that to the Radeon R9 M295X, which features a GPU core clock speed of 750 MHz, and 4096 MB of GDDR5 memory set to run at 1375 MHz through a 256-bit bus. It also features 2048 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 7950 3GB should perform a lot faster than the Radeon R9 M295X in general. (explain)
Texel RateThe Radeon R9 M295X will be a small bit (more or less 7%) faster with regards to texture filtering than the Radeon HD 7950 3GB. (explain)
Pixel RateThe Radeon HD 7950 3GB is a little bit (approximately 7%) faster with regards to AA than the Radeon R9 M295X, and also should be able to handle higher screen resolutions better. (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 megabytes per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at 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 the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends 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.
