Hi Witty,

in the past the answer was a clear yes, but today the synthesis engine of Quartus is quite good. In my experience you can expect in average a fmax improvement of 10%. Sometimes you will get more, especially when you use the retiming feature. The QoR depends on the design, so I would recommend to run some benchmarks with some of your typical designs. If you need more improvement you should try SynplifyPremier, which uses additional Placement information for the synthesis.

Kind regards
