It is likely he did not have a quad or even a dual core but you can see Fritz10 does not agree with those moves at 3 minutes per move. Fritz10 may be "weak" but ask Kramnik what happened. White's opening choices were not the best so in addition to getting decent hardware he may get a good book.

I see that you use Fritz in multi-pv
At least in the second case Rxg7 get the same score as the best move and I am interested in analysis without multi-pv that shows the depth and the score..
