AMD's new mobile Ryzen 4000 "Renoir" family — first teased at CES 2020 — has now been released. The 4000 mobile family marks a move from Zen+ to Zen2 cores, matching the 3000 desktop family. This is a significant development that accounts for a large portion of the generational performance and stamina changes.

Looks very promising, now bring on the reviews! We've already seen that you have a Lenovo in the pipeline and that it performs well (you shouldn't let pre-release data be available to add to your comparison tables ;) ), but I'm eager to see the full review.
Really looking forward to these chips, hopefully they give Intel a proper run for the money and performance. Now waiting for brands to start offering these up in some ultrabooks.
