Look at the spec sheets of different iPads and you’ll notice two very different families of Apple chips: the A series and the M series. Understanding the difference helps you gauge how much “future-proofing” a model actually has before you buy it.
What it is, in detail
A-series chips (like the A16 on the base iPad or the A17 Pro on the iPad mini) are the same processor family used on iPhone, adapted for tablets. They’re designed to balance power and energy consumption in a compact device, and offer more than enough performance for browsing, streaming, light productivity, and most available apps.
M-series chips (like the M4 on the iPad Air, M5 on the iPad Pro) are instead the same processor family used on Mac computers, adapted for iPad. They offer more CPU cores and, above all, a much more powerful GPU, plus support for more RAM: this translates into much wider headroom for heavy multitasking, video editing, 3D rendering, and professional graphics apps.
Why it’s not just “a higher letter/number is better”
It’s easy to assume an M-series chip is always “better” than an A-series one, but the right question is: do you actually need that extra power? For everyday use — email, social media, streaming, browsing — even recent A-series chips aren’t a real limitation. The difference only becomes noticeable once the workload increases significantly.
What to actually look at
If you’re weighing an iPad and wondering whether an A-series chip is enough, think about the apps you’ll genuinely use: if they stay light (browser, email, streaming, notes), an A-series chip is perfectly fine. If you’re planning on video editing, professional graphics apps, or multitasking with several apps open at once, an M-series chip gives you a performance margin you’ll appreciate over time, not just at launch.
