is this model number is genuine MYD82LL/A? i cant find in apple website

Using a search engine (such as duckduckgo) helps a lot.

The model appears in Apple pages, as M1 MacBook/Pro

13-inch 2020+ (first item in article below w/ specs)

• Identify your MacBook Pro model - Apple Support

https://support.apple.com/en-us/HT201300

This section shows M1 -and- Intel-based MB/Pro 13-inch.

https://www.apple.com/macbook-pro-13/specs/

Not sure what you mean, because the Apple store page

cited above, has Overview/Specs/Buy/ ... also sales info.

..You can choose between M1 and 'Intel-based' 13-inch

MacBook Pro & buy from this official Apple Store page:

https://www.apple.com/shop/buy-mac/macbook-pro/13-inch

[And there's also a 16-inch 'Intel-based' MB/Pro, linked there too.]

When you go into Apple online store site, the page goes to Buy.

After selecting the options, (as these are not upgradeable after

purchase) the model number of your chosen one, is visible.

Be sure you select the highest spec because there are no after-

market memory or storage upgrades. The 'base' model has fewer

configuration choices in M1 MacBook Pro.

Example of one from Amazon only has mild upgrade storage,

(256/512GB SSD) and lower end of (8/16GB RAM) options.

The Graphics portion of specs, is integrated with CPU; and

the unit has System on Chip.

You should study the Apple links and use the search to find more.

This one has lower spec GPU/CPU, of one set specs they show.

I'd study and look further for important details before ordering

from Amazon. They may offer lower price, but that's not enough.
