Yes, obviously, or AMD wouldn't have designed a processor that way. But I don't actually know the answer to your question.

A quick google search of "ryzen victim cache" (https://lmgtfy.com/?q=ryzen+victim+cache) shows a number of people discussing the issue, but mostly just re-iterating the same points over and over.

The question is, which (types of) applications have sucky performance specifically because of this? It may be a perfectly reasonable design choice for some/many use cases.

I found the thread where Jim Thompson of Netgate (gonzopancho) talks very briefly about the Ryzen cache architecture:
