![]() I'm not trying to start an argument about expectations here, I'm just trying to verify of A) this is similar to what other MBP users have experienced and B) is there a way to alter this that I don't know about? There used to be a command line option with pmset in Terminal to control the CPU speed management but it was removed a few versions of Mac OS ago. I can reasonable assume that the turbo algorithm is less aggressive due to either microcode in the mobile CPU part or manipulation on the part of Apple to optimize battery life. ![]() I would expect at least 3.5 in the single voice scenario. I only get to 3.3 with playing a couple handfuls of voices and pegging the Logic CPU meter. ![]() With the exact same stuff running and the same logic project, I'm seeing 3.0 (base clock) on the MBP. With nothing but Logic and a single voice on a single track, the iMP is clocking at close to the max single core turbo - 4.2 vs 4.5 - reasonable since there are very low levels of activity on other cores & consistent with published observations. The MBP is on wall power BTW.Ĭurious what other MBP users see and has anyone else noticed big differences in performance between similarly spec'd MBP i7's and iMac's or Mac Pro's? The large disparity in clock speed appears to be the primary contributing factor in the LPX CPU differences. While the iMac Pro attempts to maximize CPU speed, staying around 4.0 - 4.2 GHz for lighter loads (like playing a single track), the MBP won't go above its base clock (3.0) unless I grab a handful of voices in a very CPU intensive Omni multi. I used Intel Power Gadget to look at what the CPU speed is doing on both and got a big surprise. However there is a HUGE difference in the indicated realtime CPU load within Logic that is largely independent of what audio interface I use (I have tried both with the internal as well as my RME UCX - the UCX is better but not nearly enough to close the gap). The Geekbench single core benchmarks are also in the ballpark (5200 iMP vs 4600 MBP as I recall). Both machines are similar architecture (except for more cache in the Xeon) and similar base clocks and turbo frequencies. Main rig is 10 core 3.0GHz iMac Pro, laptop is 3.1GHz Kabylake. I decided to set up my 2017 15" MBP w LPX as a travel rig. So I just ran into a problem I'm guessing several of you have dealt with, and I'm hoping for some guidance.
