Compare any two graphics cards:
GeForce GTX 970 vs Radeon HD 7770
IntroThe GeForce GTX 970 comes with a core clock speed of 1050 MHz and a GDDR5 memory speed of 1750 MHz. It also features a 256-bit bus, and uses a 28 nm design. It is comprised of 1664 SPUs, 104 TAUs, and 64 Raster Operation Units.Compare those specs to the Radeon HD 7770, which has a core clock speed of 1000 MHz and a GDDR5 memory frequency of 1125 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce GTX 970 should be quite a bit faster than the Radeon HD 7770 in general. (explain)
Texel RateThe GeForce GTX 970 should be quite a bit (more or less 173%) faster with regards to texture filtering than the Radeon HD 7770. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTX 970 is a better choice, by far. (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 data (counted in MB per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 are processed in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka 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 potential to get to the max fill rate.
