Compare any two graphics cards:
GeForce GTX 970 vs Geforce GTX 780
IntroThe GeForce GTX 970 comes with a GPU core clock speed of 1050 MHz, and the 4096 MB of GDDR5 memory runs at 1750 MHz through a 256-bit bus. It also is made up of 1664 Stream Processors, 104 TAUs, and 64 ROPs.Compare that to the Geforce GTX 780, which makes use of a 28 nm design. nVidia has clocked the core speed at 863 MHz. The GDDR5 memory works at a speed of 1502 MHz on this particular model. It features 2304 SPUs as well as 192 TAUs and 48 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Geforce GTX 780, in theory, should perform much faster than the GeForce GTX 970 overall. (explain)
Texel RateThe Geforce GTX 780 is quite a bit (about 52%) better at AF than the GeForce GTX 970. (explain)
Pixel RateThe GeForce GTX 970 will be quite a bit (more or less 62%) more effective at AA than the Geforce GTX 780, and also 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 largest amount of data (in units of megabytes per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 can be processed per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video 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 maximum amount of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock 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 output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.

2 Responses to “GeForce GTX 970 vs Geforce GTX 780”This comparison is slightly misleading. Maxwell is more efficient than Kepler and so a narrower bus width (256 -bit for Maxwell, 384-bit for Kepler) does not mean Maxwell is objectively slower than its respective Kepler counterpart. A direct (paper spec) comparison will always be significantly misleading in this regard, when comparing Maxwell to previous generations.
How it make GTX 780 20M/s Ethereum Mining !
it's very hard i think to do that ?
