Compare any two graphics cards:
Radeon HD 5870 vs Radeon R9 M275X
IntroThe Radeon HD 5870 makes use of a 40 nm design. AMD has clocked the core speed at 850 MHz. The GDDR5 memory is set to run at a frequency of 1200 MHz on this particular model. It features 1600(320x5) SPUs as well as 80 TAUs and 32 ROPs.Compare those specs to the Radeon R9 M275X, which features a GPU core clock speed of 900 MHz, and 2048 MB of GDDR5 RAM running at 1125 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 5870 should theoretically perform much faster than the Radeon R9 M275X overall. (explain)
Texel RateThe Radeon HD 5870 should be much (more or less 89%) more effective at texture filtering than the Radeon R9 M275X. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon HD 5870 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: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could 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 Raster Operations Pipelines by the clock 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 output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
