As Falcon does not yet support multi-threading, the faster your CPU is, the better. On my main studio rig I use a Mac Pro (ashtray model from late 2013), 2.7 GHz, 12-core Intel Xeon E5 processors. This works fine with most of my Falcon patches but of course totally depends on the buffer size in your DAW or in Falcon standalone. My new music laptop for live performances is a Macbook Pro from late 2018 with 6 cores i9, 2.9 GHz and it handles the Falcon load slightly better of course.
