Compare any two graphics cards:
Radeon R7 250 vs Radeon R9 M280X
IntroThe Radeon R7 250 uses a 28 nm design. AMD has clocked the core speed at 1000 MHz. The GDDR5 RAM runs at a frequency of 1150 MHz on this specific model. It features 384 SPUs along with 24 TAUs and 8 ROPs.Compare those specifications to the Radeon R9 M280X, which has GPU clock speed of 900 MHz, and 4096 MB of GDDR5 memory set to run at 1375 MHz through a 128-bit bus. It also is comprised of 896 Stream Processors, 56 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon R9 M280X should be just a bit faster than the Radeon R7 250 in general. (explain)
Texel RateThe Radeon R9 M280X is quite a bit (approximately 110%) better at AF than the Radeon R7 250. (explain)
Pixel RateThe Radeon R9 M280X should be quite a bit (approximately 80%) better at FSAA than the Radeon R7 250, and also will be able to handle higher resolutions while still performing well. (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 (measured in MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the 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 are applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
