I would think the Core-M models would perform better than the previous i5 Y models of the Venue 11 Pro leaving the Atom Models at the low end. However, I noticed some articles comparing it to the Atom version. No doubt the Atom entries will get updated later after the 14nm Atom family (Braswell) is introduced.
