Haven’t yet run into any memory issues.Ĭlick to 's not clear if that changed the RAM requirements or just saved disc space (I doubt that the Intel code ever got loaded on a PPC machine, or vice versa). I have an 8GB M2 Air and I regularly push it to play games, record and master audio, and occasionally archive and encode video. They never had that with Intel, they just had to take whatever Intel had on the shelf and make do. Moving to their own silicon meant they could once again highly optimize the code base because, like in the AIM days, the CPUs are made only for the Macintosh. Long story short Apple had to take a much less optimized approach to coding OSX during the Intel phase to accommodate CISC execution. PPC was also a RISC based design, so the code was smaller. In order to save multiple gigabytes of hard drive space there was a utility around at the time of OSX Leopard that would strip the Intel code from binaries if you had a PowerPC machine, which made them up to 2/3rd smaller in my experience. I had both an iBook G4 and a brand new Core Duo Mac Mini at the time and the Mini suffered from slowdowns and beach balls a lot more frequently than my trusty Book did. Not everyone here will remember this but when Apple switched to Intel they carried over the 512MB of memory base model machines came with, and it simply wasn’t enough for Intel versions of OSX. The number of functions the CPU can perform are reduced but the ones that are present are considerably faster.Īnd the second is code bloat. One is ARM processors run a RISC instruction set instead of CISC. Peace.Ī lot of folks think Apple are just being cheap, and I don’t disagree, it’s not like it costs that much more in parts costs to equip these machines with 16GB instead of 8GB, especially given what they charge for even the cheapest of their machines.īut there is technical merit to the “more efficient” claim for two reasons. Didn't keep my 2019 that long because of the transition and massive improvements to heat and battery life, but I plan to keep my upcoming MBP M3 Max for about that long!Īnyway, just thought that was interesting. Heck, I'm a professional and I kept my maxed out 2012 retina MBP for nearly 7 years. You can't tell me this 8GB system won't be crawling when it gets macOS 20 in six years! And a lot of regular people keep their computer that long or longer. For normal users, it will significantly shorten the usable lifespan of their computer with regard to future OS updates. And while it will work, evidence has shown that more memory helps, especially in AI applications for loading the model into memory, not to mention other applications like video rendering, etc. 8GB still isn't enough for a professional user if they ever plan to do more than one thing at a time. While I wouldn't recommend 8GB even to my grandfather, it's still interesting that there is something real and tangible to this whole story, as evidenced above. Memory compression goes a long way, and having unified memory can really help out apps like this that can be so GPU intensive doing AI stuff. So it seems like there is some real world evidence for this argument, although I feel like 12GB is probably closer to the real answer, and I thought as much when that story came out.
