This is more or less accurate: almost all of the other top 10 firms pay $160k base with a $10k pro-rated bonus (http://abovethelaw.com/2013/12/breaking-cravath-announces-ye...).
One funny thing about making the engineer-to-lawyer comparison regarding this salary fixing issue is that law actually has a much more obvious salary fixing problem, since almost every biglaw firm pays 160k and firms don't tend to compete for entry-level hires with compensation.
