May sound like a stupid question (sorry) but what is Zen 3?

The name of the architecture that Ryzen 5000 series processors are made out of.

 

First gen (Ryzen 1000):

Zen

Second gen (Ryzen 2000):

Zen +

Third gen (Ryzen 3000):

Zen 2

Fifth gen (Ryzen 5000):

Zen 3

 

Although, AMD stopped using the term "generation" in an official capacity some time after second gen so technically the Ryzen 5 5600X isn't "fifth gen", it's only "5000 series"

 

Also, APUs are known to use the last gen's architecture. The Ryzen 3 2200G is a second gen part, but uses Zen architecture instead of Zen +, while the Ryzen 3 2300X uses the advanced Zen +. The missing "fourth gen" processors are all APUs (the Ryzen 7 4700G and such) and they all use Zen 2 architecture, and they are also OEM only so they never saw a normal retail release.

Zen 3 is the codename for a CPU architecture, made by AMD.

Much of AMD's current CPU's (like Ryzen 5000 on desktop/mobile and certain Epyc server/workstation CPU's) are based on this architecture.

Here is a list of the current Zen 3 CPU's: https://en.wikipedia.org/wiki/Zen_3#Desktop_CPUs

 

Before Zen 3 we had Zen 2, before that Zen+ and before that Zen.

My new motherboard says that its compatible with 3th gen CPUs, but the bios are compatible with zen 3 (i have a 3700x), does that mean that i need to use a Flash?

If your motherboard says "ryzen 3000 ready" on the box, it is compatible with the 3700X since that's a 3000 series part. 

 

You can also identify compatibility with some easy steps. Every B350 and X370 motherboard is guaranteed compatible with first gen. Every B450 and X470 is compatible with second gen. Every B550 and X570 is compatible with third. There are some special cases, like the MSI MAX series of B450 motherboards designed for the 3000 series processors. Those are also guaranteed compatible.

 

If your motherboard does not have the "Ryzen 5000 ready" badge on the box, you would need to flash the bios for something like a 5800X. But that's just an example. The BIOS version of whatever motherboard you have is based on when it was manufactured. For example, most B550 and A520 motherboards will have "ryzen 5000 ready" on the box because they were released a very short time before 5000 series processors were.
