GeForce GTX 780 Ti vs GeForce GTX 970
Intro
The GeForce GTX 780 Ti features a core clock speed 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 specs 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 along with 104 TAUs and 64 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in MB per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total texture units of the card by the core clock 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 most pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate 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 drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach 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.
