Compare any two graphics cards:
GeForce GTX 980 vs Geforce GTX 780
IntroThe GeForce GTX 980 uses a 28 nm design. nVidia has clocked the core speed at 1126 MHz. The GDDR5 memory is set to run at a speed of 1750 MHz on this model. It features 2048 SPUs as well as 128 TAUs and 64 Rasterization Operator Units.Compare all that to the Geforce GTX 780, which features a core clock frequency of 863 MHz and a GDDR5 memory speed of 1502 MHz. It also uses a 384-bit bus, and uses a 28 nm design. It is comprised of 2304 SPUs, 192 TAUs, and 48 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Geforce GTX 780 should theoretically perform a lot faster than the GeForce GTX 980 in general. (explain)
Texel RateThe Geforce GTX 780 is a bit (more or less 15%) faster with regards to anisotropic filtering than the GeForce GTX 980. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GTX 980 is the winner, 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: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the 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 can be processed per second. This is worked out 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends 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.

Comments
One Response to “GeForce GTX 980 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.
