I did another stress test. This time using LASS (a high end, professional String Virtual Instrument) inside of Reaper. I purchased a Mini Dual SSD enclosure from Other World Computing. I put my 2 sample drives in that unit and connected via USB-C to the MBP. These are thier 3G SSD drives, so not the super high performance drives that they offer. But these came out of my MP, so it is a good comparison.
I didn’t run this particular test on my MP, but if I remember correctly, I was able to get about 30 or so tracks of heavy Virtual instrument use before it began to struggle. If I get some time, I may try it again and double check it.
With the MBP, I was able to do 96 tracks of LASS running multiple articulations on a 8 bar loop and Reaper was showing a CPU use of 36-41% I was going to continue adding tracks, but honestly, I got bored trying to max this thing out. 96 tracks at only 41% CPU usages is mind blowing to me.
Also, did I mention that I think this MBP shipped without a fan? As I have yet to hear it come on, where my MP would start the fan up almost instantly after hitting play on some heavy use.
My final test will be with Omnisphere (a very CPU heavy Synth) that I am going to do today. But I can say without a doubt this MBP far exceeds my expectations. I am constantly blown away with what this Mac can do. And all this with just 16GB Ram - as opposed to my MP which had 64GB! Crazy.
Last of my tests today. Again, using Reaper. I made a track with Omnisphere and picked the biggest patch I could (quickly) find Imperial March Movement. Omni reports this is a 1442MB Patch. I made a simple 8 bar pattern and set it to loop/repeat. I then duplicated the track until I was getting clicking.
I stopped at 175 tracks!! 175 tracks of Omnisphere, streaming from a USB-C SSD drive (running on bus power)! EDIT: My MP doing the same test was able to do 90 tracks before choking. So better than I remembered, but still about half what this MBP is doing.
The only downside is I lost my area heater that was my MacPro - that thing helped warm up the temp in my studio!
Happy to run other tests if you would like something else. But I am through testing this Mac. There is never a day I will need 175 tracks of Omni. My concerns that 16GB wouldn’t be enough (coming from 64) are finally put to rest.
