Unless you are using the chips for something like compiling source code or running VMS, in which case the workloads scale almost linearly and the Zen lineup ends up looking like great value for money.
I said "in this price range". Who is using the lowest-end chips? It's not coders or creators. It's not gamers. It's people browsing the web. The responsiveness is the biggest performance metric in that case, and is directly related to straight-line performance.
I grew up in a developing country, for a long time my computer purchase decisions were overwhelmingly driven by price. Cheaper SKUs see far greater diverse use than you suspect.
