And a couple older machines with discrete graphics that do fine-ish with Zoom. We have old machines that run great for the software we use them for, that simply cannot do anything with Zoom, other than display a slideshow instead of video. Older, integrated Graphics computers suffer badly since they try and do everything with the CPU, instead of hardware, and on top of that, their Intel processors are just weak compared to what is running in recent iPhones. Intel has really fallen behind Apple is making fast processors, both CPU and GPU, and really, really fallen behind in mobile processors. The iPhone 11 and the latest iPod Pro are the fastest computers Apple ever made outside of the Mac Pro ($10,000+), and the latest iMac Pro ($5000.00+). The performance difference in video playback and encoding between older Macs, and current Macs is pretty stark. If you have a laptop with discrete Graphics (which, in Macs, means a MacBookPro, and nothing else), you will have real trouble with Zoom. The latest graphics cards, even the integrated ones, do almost all of the heavy lifting for Zoom in hardware. If there is no hardware acceleration any computer would have trouble with Zoom, and older Mac laptops simply have no useful hardware acceleration. Zoom has a real hard time running usefully on some older Mac laptops, that can otherwise be useful, because of the antiquated graphics cards.
