Compare any two graphics cards:
GeForce GTX 970 vs Radeon HD 6770
IntroThe GeForce GTX 970 comes with a GPU core speed of 1050 MHz, and the 4096 MB of GDDR5 memory is set to run at 1750 MHz through a 256-bit bus. It also is comprised of 1664 Stream Processors, 104 TAUs, and 64 ROPs.Compare all that to the Radeon HD 6770, which has GPU core speed of 900 MHz, and 512 MB of GDDR5 memory running at 1050 MHz through a 128-bit bus. It also is made up of 800 Stream Processors, 40 Texture Address Units, and 16 ROPs.

3DMark Fire Strike Graphics Score
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 970 is 233% quicker than the Radeon HD 6770 in general, due to its greater bandwidth. (explain)
Texel RateThe GeForce GTX 970 will be a lot (more or less 203%) more effective at anisotropic filtering than the Radeon HD 6770. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 970 is superior to the Radeon HD 6770, 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: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
