Compare any two graphics cards:
GeForce GTX 580 vs GeForce GTX 970
IntroThe GeForce GTX 580 features clock speeds of 772 MHz on the GPU, and 1002 MHz on the 1536 MB of GDDR5 RAM. It features 512 SPUs along with 64 TAUs and 48 Rasterization Operator Units.Compare those specifications to the GeForce GTX 970, which makes use of a 28 nm design. nVidia has set the core frequency at 1050 MHz. The GDDR5 memory is set to run at a frequency of 1750 MHz on this particular card. It features 1664 SPUs as well as 104 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 970 will be 16% faster than the GeForce GTX 580 overall, due to its greater data rate. (explain)
Texel RateThe GeForce GTX 970 will be a lot (approximately 121%) better at AF than the GeForce GTX 580. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GTX 970 is a better choice, by a large margin. (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 (counted in MB per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better 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 amount of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
