Nvidia also changed the streaming multiprocessor design from that of Kepler (SMX), naming it SMM. Accordingly, Nvidia cut the memory bus from 192 bit on GK106 to 128 bit on GM107, further saving power. Nvidia increased the amount of L2 cache from 256 KiB on GK107 to 2 MiB on GM107, reducing the memory bandwidth needed. These new chips provide few consumer-facing additional features Nvidia instead focused on power efficiency.
