The latest top quark mass measurement from ATLAS (at the LHC) is 172.99 +/- 0.91 GeV.
By comparison the PDG value is 173.21 +/- 0.87 GeV.
A somewhat more recent combined value (because it considers pre-prints and not just published papers) is 173.34 +/- 0.76 GeV.
An extended Koide's rule estimate of the top quark mass using only the electron and muon masses as inputs, predicted a top quark mass of 173.263947 ± 0.000006 GeV.
A prediction that I made in March 2014 which assumed a Higgs bosons mass of about 125.96 GeV and some other assumptions (some of which are just conjectures themselves), predicted a top quark mass of 173.1125 ± 0.0025 GeV.
Of course, the latest experimental value is consistent with all of the other values due to a lack of experimental precision in the top quark mass measurement, which is improving over time, but ever so slowly.
