Quite simply AMD put up their chip, on a like for like basis, wouldn't surprise me if that AMD chip was clocked around 4.5ghz either. So they put their 8c 16t vs Intels 8c 16t chip, unfortunately in this instance for Intel, AMD's chip while being an ES and probably still not the final clocks, was matching it for performance at a lower power, if theres room left in that tank then AMD have beaten Intels high end with their own mid range, as AMD have an ace up their sleeve with another set of cores able to be bolted on.
The only question i have with that regard though is heat... we dont know how hot that 8c 16t AMD chip was, it was on an air cooler sure, but was that a Wraith Cooler? or was it like a Phanteks level of air cooler? we cannot tell, as we have no specifics. Im inclined to believe that the power draw was pointing at that AMD chip not being aggressively clocked and still matching a stock 9900k.
Now if we put 2 of those chips on a package the size of ryzen thats a lot of heat we need to dissipate, they could be clocked lower to keep thermals in check, we just dont know.
As someone above has said, with yesterday out of the way we should now start seeing more leaks coming through about actual specifics. If the X570 motherboards are being touted around to reviewers already this could be very good as well.
Also i read somewhere last night that PCIE4.0 may well be able to be pushed to First and 2nd Gen Zen motherboards? big if true.
