To re-iterate: you have no basis for saying it is high performance because it has not been shown to be so.
When a track record has been established _then_ claims of this kind can be made, but not before.
I have worked with chip makers at both ends (I was doing games which they used for testing, but they also tried to get our input for what their next designs should do) and honestly learned that these people are absolute dreamers. This was not helped by the nearly constant regularity with which we found performance destroying design flaws. Some prototypes were aborted as a result (dramatic overheating is quite a problem) but most products launched to go nowhere since they were now unspectacular.
The dreaming is necessary to enable them to get up and try again, but it means you should not believe a word they say until it works.
Realistically, there's no way every company that has high performance microarchitectures available for licensing is lying, and that the clients it already licensed the IP to are covering for them.
It is also unreasonable to think that each and every industry veteran who has designed successful, competitive high performance microarchitectures in the past and is now working on RISC-V IP is for some reason suddenly unable to deliver.
Waiting will give you confirmation, in the form of seeing your competitor's successful products in the market, but at the cost of missing your own chance.
