I’m running a 2013 iMac i7 quad-core 27” with 24GB RAM and 10.13 High Sierra. I’ve been waiting for 2-ish years now wanting to update to Apple Silicon and a newer system. I was hoping to get another all-in-one iMac with the larger screen (and the smaller iMacs never come with the more powerful options).Picking up on this rather late sorry, but figured I'd give it a few weeks of experience before I came back with my comments. Have to say, for many in-app activities, I don't find this new machine massively faster than my 2011 i7 quad-core iMac with a 250GB Samsung SSD and 16GB RAM, and which, without wanting to sound condescending, was almost certainly faster than your 2014 MBP and definitely your 2012 Mac Mini (so your experience of migrating to an M1 is going to be different to mine).
Bouncing Logic projects laden with a dozen virtual synths and effects takes roughly the same time as my iMac, even when using only Logic-native plugins which have all been optimised for M1. It's probably a bit faster, but not so much where I've said oh wow holly s___ look at that, how did I survive before this.
Loading WAV files into iZotope RX6 and running my usual workflow of Loudness normalise to -10dB LUFS with a peak of -0.2dB takes roughly the same time as it did on the iMac, though fair enough this is an Intel app being loaded through Rosetta. Again, it probably is a bit faster, but not so much where it's clearly noticeable without a timer.
Credit where credit is due, I have noticed an improvement of roughly 10-15% when rendering simple videos with a few titles and wipes through iMovie (I have no need for FCP).
Was it worth it? Definitely: I'm now running a supported system with enough spec-overhead to hopefully give me ten years of life from it, same as I got from my 2011 i7 iMac when I purchased it. But, gotta be honest, looking at my workflows, very little speed-wise has yet totally blown me away compared to what I was used to, other than how fast the machine boots and how fast it loads apps and saves files, all of which can be explained by the approx 10x faster R/W compared to the SSD in my i7 iMac. If anything, I have even more respect for my 11 y/o iMac than I had before, which was obviously such a total beast, irrespective of benchmarks that would suggest it would be completely annihilated by an M1 iPad.
Now that it seems like it will likely be at least 1-2 more years before we see a larger iMac (if they do release one), I’m thinking I may have to either get a Studio or a laptop + monitor (probably the latest Apple display). I‘ll admit that iMacs have many shortcomings (and in the event of a problem, the monitor and ‘computer’ are tightly integrated, making repairs involved)—my 27” screen has had dust trails for several years now, you can easily see the fan air pathways under the screen—but I do reallly like the simplicity of the AIO.
Thanks for sharing your experience of this Studio. And, your setup is gorgeous. I’m not a musician, but I do really like seeing the equipment and processes involved in modern music creation.
