GeForce GTX 780 Ti vs GeForce GTX 970
Intro
The GeForce GTX 780 Ti comes with a core clock frequency of 875 MHz and a GDDR5 memory frequency of 1750 MHz. It also uses a 384-bit memory bus, and uses a 28 nm design. It is made up of 2880 SPUs, 240 TAUs, and 48 Raster Operation Units.Compare those specifications to the GeForce GTX 970, which has clock speeds of 1050 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 RAM. It features 1664 SPUs as well as 104 TAUs and 64 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher 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 number of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.

Comments
2 Responses to “GeForce GTX 780 Ti vs GeForce GTX 970”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.
@jchap
True, though the comparison does not take architechture differences into account.
In fact, if you look at the benchmarks, it would appear GTX 970 is slightly faster than the 780Ti in most tasks and games.
But it also consumes much less electricity, and costs 50% less.
