the fact
I'm always willing to have an objective discussion and I'm open to proof.
a 300$ Lenovo AMD Ryzen 3 7th series
Tried looking for it, it doesn't seem to exist. You're welcome to provide a link. So far it seems a myth, not a fact.
AMD Ryzen 3 7th series
I'm guessing you mean "7000 series". If it is a $300 laptop with a 7000 series APU, then it would have to be the Mendocino series which is Zen 2 or second gen Ryzen, the same architecture as the Ryzen 5 3600.
will wipe the floor with it, from all aspects
The CPU performance will be better, I won't deny that. However a Honda Civic or a Lamborghini will both take you to the grocery store just fine. For typing up homework and finding sources online I don't need a super powered computer, I have a 5900x, 3090, and 64GB DDR4-4000 at home which can do anything I need. Worst case I can remote desktop to it.
Now after researching this, I was able to find one laptop that's close-ish to what you described:
https://www.lenovo.com/us/en/p/laptops/ideapad/ideapad-100/ideapad-1-gen-7-(15-inch-amd)/82vg0041us/82vg0041us)
But it hardly "wipes the floor":
| My Laptop | Idea Pad 1 Gen 7 | |
|---|---|---|
| Price | $280 (180+100 upgrades) | $399 (140% the price) |
| LCD | IPS | TN |
| Resolution | 1080P | 1080P |
| WiFi | 2.4, 5, & 6 Ghz | 2.4 , 5 Ghz (no 6Ghz) |
| RAM | 20 GB | 4GB |
| RAM Slots | 4GB soldered, 16GB added in 1 slot | 4GB soldered, no upgrades slot |
| SSD | 500GB | 128GB |
| SSD Type | SK Hynix P31 | Generic |
| CPU Cores | 2 | 2 |
| CPU Brand | i3 | Athlon (worse than Ryzen) |
| CPU Architecture | Ice Lake | Mendocino |
IPS was one of my top priorities, as I wanted a decent screen on it:

The Dual Core Athlon 7220U is not yet on Passmark, but if we compare a quad core Ice Lake CPU to a quad core Mendocino there's about a 12% performance difference:

That's a small difference given that nearly everything else is a vast downgrade.
I find it hard to believe that Lenovo would have a laptop with double the cores, quadruple the RAM, and quadruple the SSD capacity for $100 less. Even then my laptop would probably still have a better LCD.
Acer has a $400 laptop with an IPS display, and a quad core Ryzen 3 7320U:

But it still has many disadvantages like:
* 128 GB SSD
* 8GB RAM
* No 6Ghz WiFi
* Worse keyboard than Lenovo
* Soldered RAM
