No? Vega 10 is the arch name, it's supposed to be at least on par with 1080ti (again, supposed), why do i have the feeling you got it all wrong?
Back in early 2016, everything pointed towards there being a bigger Vega 11 GPU and smaller Vega 10 GPU. Then some time later Vega 10 became bigger GPU, Vega 11 smaller one. After even more time, Vega 11 completely disappeared and only Vega 10 was talked about.
Also I don't think "Vega 10" is the uarch name. Vega 10 is a code name for GPU (like Hawaii, Tonga, Fiji, Polaris 10/11 etc.).
Unless AMD comes up with the new name for the massively refined GCN that Vega will be based upon I guess name will be GCN5 (Polaris cards being based upon GCN4).
