If you’ve used Macs for a long time, say over 25 years, you might recall the original processor migration. Then it was the journey from Motorola 680×0 chips to the PowerPC, said to be the ultimate processor. But it wasn’t such a friendly change.
For one thing, just about every app you used, even those from Apple, hadn’t made the trip to the new processor. So they had to run in emulation. So they’d run, more or less, about the same as Macs using the 68030 CPU, such as the IIci or the IIx. If you were upgrading from a Quadra, for example, using the 68040 CPU, you lost the performance advantage till the apps were updated.
Now if you weren’t using Macs way back then — or weren’t even around — no worries. Most of this should be pretty clear anyway. Apple as “vintage” for several years), and a Late 2014 iMac (which has just been declared “vintage”).
