Check your macOS menu bar and select the Apple logo. A drop-down menu will appear on the screen. Click on About This Mac. Check the label displayed on the screen. If your Mac uses Apple Silicon, the item displayed will be labeled "Chip". Otherwise, it will show an item labeled "Processor". The processor label will show that your Mac uses an Intel processor. Some other important details about your Apple Silicon or Intel processor will also be displayed. These will help you know if it's Core i5, i7, M1 chips, or M2 chips. Aside from using this info for booting your macOS from USB, it can also help you know about your battery health, performance efficiency for heavy-duty, and processing speed.
