Compare any two graphics cards:
Radeon HD 7750 vs Radeon R7 240
IntroThe Radeon HD 7750 uses a 28 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 memory is set to run at a frequency of 1125 MHz on this model. It features 512 SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.
Compare those specs to the Radeon R7 240, which features a GPU core clock speed of 730 MHz, and 2048 MB of DDR3 memory set to run at 900 MHz through a 128-bit bus. It also is comprised of 320 Stream Processors, 20 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon HD 7750 should theoretically be much faster than the Radeon R7 240 in general. (explain)
Texel RateThe Radeon HD 7750 is much (approximately 75%) better at AF than the Radeon R7 240. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon HD 7750 is the winner, by far. (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.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of MB per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type memory, 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 anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units of the card 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 in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core speed of the card. 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 fill rate is also dependant 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.
