AMD Ryzen 2000 or AMD Ryzen 3000?

Question

AMD

Well, in general, the title is the whole point.
I'm building a new computer and I hesitate in choosing a generation only because I've heard a lot about Specter / Meltdown.
And AMD seems to have fixed this in Zen 2.
Is it really a performance hog to protect against these vulnerabilities?
PS Comp for system programming, development of boards and all things that will be in 2-4 courses.
I am also seriously fond of writing music, I will also use it for this

Answer 1

if you have money, take 3000, if not, or the toad is choking, take 2000 calmly

Answer 2

Specter/Meltdown are vulnerabilities that require either a well-targeted attack or a very long time to exploit. This is when one process in the system can receive data from other processes, outside of access control, and this can be done even with javascript from the browser (only even longer).
The complexity of exploiting vulnerabilities is so high that, roughly speaking, it is necessary that the extracted data be valuable enough to pay off the effort. And in the case of a browser, a malicious web application must run in the background (noticeably loading the processor) for a noticeably long time.
An ordinary layman does not have such data, or rather, it may be information about a bank account or the same cryptocurrencies. Based on this, it is possible (and necessary) to stop these attack vectors in more 'cheap' ways - using hardware wallets or additional hardware used exclusively for these critical tasks.
Those. buy the cheapest laptop / tablet (about 5-13t.r.) and use it for money-critical tasks. Do not run anything other than banking applications and wallets on this machine, do not install any unnecessary applications on it, and if possible, place this machine on a neighboring local network at all (many consumer routers can build a network of several local ones and divide by vlan)
