Compare any two graphics cards:
GeForce GTX 1070 vs Radeon HD 7950
IntroThe GeForce GTX 1070 features a clock frequency of 1506 MHz and a GDDR5 memory frequency of 2000 MHz. It also makes use of a 256-bit bus, and uses a 16 nm design. It is comprised of 1920 SPUs, 120 TAUs, and 64 Raster Operation Units.
Compare that to the Radeon HD 7950, which comes with core speeds of 800 MHz on the GPU, and 1250 MHz on the 1536 MB of GDDR5 memory. It features 1792 SPUs as well as 112 TAUs and 32 Rasterization Operator Units.

As far as performance goes, the GeForce GTX 1070 should in theory be a bit better than the Radeon HD 7950 in general. (explain)
Texel RateThe GeForce GTX 1070 is a lot (about 102%) more effective at anisotropic filtering than the Radeon HD 7950. (explain)
Pixel RateThe GeForce GTX 1070 will be a lot (more or less 277%) faster with regards to FSAA than the Radeon HD 7950, and also capable of handling higher screen resolutions more effectively. (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: Bandwidth is the maximum amount of information (counted in MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at 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 can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
