AMD is expected to flesh out its second generation Ryzen processor family with additional SKUs, specifically the Ryzen 5 2500X and Ryzen 3 2300X, neither of which have officially been announced yet. However, they have made unofficial appearances in various leaks, including a recent one on Lenovo's website.

It's one thing when an unreleased processor shows up in a benchmarking database like Geekbench (it happens often, actually), but quite another when a hardware partner breaks embargo. In this case, Lenovo listed the two aforementioned CPUs among several other options for its ThinkCenter M725 line of small form factor desktops.
