Compare any two graphics cards:
GeForce GTX 870M vs Radeon HD 7970
IntroThe GeForce GTX 870M makes use of a 28 nm design. nVidia has set the core frequency at 941 MHz. The GDDR5 memory works at a frequency of 1000 MHz on this model. It features 1344 SPUs along with 112 Texture Address Units and 24 ROPs.Compare those specs to the Radeon HD 7970, which features a core clock speed of 925 MHz and a GDDR5 memory speed of 1375 MHz. It also makes use of a 384-bit memory bus, and uses a 28 nm design. It is comprised of 2048 SPUs, 128 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 7970 should in theory be quite a bit better than the GeForce GTX 870M in general. (explain)
Texel RateThe Radeon HD 7970 will be a little bit (approximately 12%) more effective at AF than the GeForce GTX 870M. (explain)
Pixel RateThe Radeon HD 7970 is quite a bit (approximately 31%) faster with regards to FSAA than the GeForce GTX 870M, and also will be capable of handling higher 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: Memory bandwidth is the max amount of information (measured in megabytes per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is calculated 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 processed in a second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
