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. -Adam -------- Original Message -------- SUBJECT: Re: [RndTbl] Ryzen latency (was: Reddit - networking - Can a BSD system replicate the performance of high-end router appliance?)

It may be a perfectly reasonable design choice for some/many use cases. On Thu, Nov 16, 2017 at 8:19 AM, Adam Thompson <athompso@athompso.net> wrote:
