No, the FP64 units aren't physically present on silicon in high numbers on the non xx100 dies.
However, limitations enforced just by the driver and its FW set:
- GPU virtualisation (see: https://github.com/DualCoder/vgpu_unlock)
- NVENC video encoder limitations to 2 simultaneous streams on customer cards
- Lite Hash Rate limitation enforcement to make GPUs less attractive for miners
