The GeForce GTX 980 Ti - part 2
Figure 8 shows the GeForce GTX 980 Ti with its cooler removed. The cooler is similar to the model we saw on the GeForce GTX Titan X. It touches the memory chips and the voltage regulator circuit transistors.

Figure 9 shows the GM200 chip. It is the same chip found on the Titan X, but with two SMM units disabled (the original chip has 24 SMM units), for a total of 2,816 cores, since there are 128 cores on each SMM. The rest of the chip specifications remain the same, like the 384-bit memory bus.

Figure 10 shows one of the 12 memory chips present on the GeForce GTX 980 Ti. It is a GDDR5 chip, model H5GQ4H24MFR-R2C from SKHynix, with 4 Gib (512 MiB) capacity and maximum clock of 3.5 GHz (7.0 GHz effective clock). So, there is no margin to overclock the video memory within its specs.

Figure 11 shows the voltage regulator circuit of the GeForce GTX 980 Ti. It uses six phases for the GPU and two phases for the memory chips, which is identical to the voltage regulator of the GeForce GTX Titan X.
