[Updated on 13 September with ratings for 8th episodes of both series.]
Ratings are in for the most recent three episodes of SG-1 and Atlantis; note that episodes 6 and 7 for both shows were up against US coverage of the Olympic Games. For episode 8, SG-1 clearly beat Atlantis in spite of SciFi’s annoying new ploy of going straight into Atlantis without showing the SG-1 credits, preview, or commercials, expressly for the purpose of trying to boost the ratings for the first few minutes of Atlantis. The real difference might be even greater.
So far the ratings for Stargate SG-1 Season 8 are as follows:
9 July: 8.01 “New Order” — 2.43
23 July: 8.03 “Lockdown” — 1.97
30 July: 8.04 “Zero Hour” — 2.16
