I took Ken Thompson's estimation (albeit from 1982) of an increase of 200 ELO for a 5x speed increase. My thinking is that if a 2x increase is 80 ELO, then a 4x increase will be 160 ELO, and a 5x increase will be 200 ELO, as Ken Thompson arrived at. My same thinking gives me 58-59 ELO for a 2x speedup from the SSDF. I must not be thinking about the problem correctly. Also, it might be that with faster hardware, a 2x speed increase might not amount to the same ELO increase as it does for slower hardware (hince why Thompson got different numbers from SSDF).
