Compare any two graphics cards:
Radeon HD 7870 XT vs Radeon R9 270
IntroThe Radeon HD 7870 XT features a clock speed of 925 MHz and a GDDR5 memory speed of 1500 MHz. It also uses a 256-bit bus, and uses a 28 nm design. It features 1536 SPUs, 96 TAUs, and 32 Raster Operation Units.Compare that to the Radeon R9 270, which uses a 28 nm design. AMD has set the core speed at 900 MHz. The GDDR5 memory is set to run at a frequency of 1400 MHz on this model. It features 1280 SPUs along with 80 TAUs and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 7870 XT should in theory be a bit faster than the Radeon R9 270 in general. (explain)
Texel RateThe Radeon HD 7870 XT will be a lot (about 23%) faster with regards to anisotropic filtering than the Radeon R9 270. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 7870 XT is a better choice, but it probably won't make a huge difference. (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 (measured in MB per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number 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 per second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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 - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
