HJL,
Almost every “Mac” made since around 2006 has been Intel-based. From a name perspective, the products were renamed with the shift.
Earlier product names included PowerMac, iBook, and PowerBook.
Intel-based product names include: Mac Pro, MacBook, MacBook Pro, MacBook Air, etc
The only two devices that didn’t get a name shift were the Mac Mini and the iMac. You can see full details at these wikipedia links, and to figure out which mac you have, you can go under the Apple Menu to “About this Mac” and it will tell you both the model as well as the processor type. – JMA
