Google Fiber outperforms Xfinity Cable on symmetric speeds up to 8 Gbps and 10-20 ms latency per Ookla and FCC data while Xfinity leads in geographic availability. Fiber wins on performance and reliability metrics from RTINGS and Consumer Reports comparisons. Cable remains viable where fiber is unavailable.
