Jesus you guys, I think it should be pretty obvious at this point that Jim was just fueling the hype train for views. According to his "sources" there should have been a 5.1 ghz 16 core chip presented back at CES. He claimed V2 didn't exist, Navi was "better than expected", and instead of back-peddling when reality hit he doubled down on Computex where he ended up being wrong AGAIN.
Let's take a trip back to CES, where after the event he immediately made a video titled "Zen 2 faster than 9900k at half the power". In the video he claimed that the CPU AMD used to demonstrate was going to be a 65 watt part. Wrong. It was much more likely a very finely tuned version of the 105 watt tdp 3800x. You can confirm this by AMD's computex slide that shows the 3700x being slower than the 9900k and the 3800x being ever so slightly faster (just like the CES demo) in Cinebench. The devil in the details of the example AMD showed at CES was how well they tuned their processor, which was probably running at 4.5ghz with lower than retail voltage, and the power consumption of everything else in the system (likely very low). It made a great marketing presentation, and plentiful fodder for those who chose not to think critically about it.
Finally, now, we have him claiming that these chips will overclock to 5ghz. His last ditch effort to not be completely wrong about everything. Well, considering how both Ryzen generations before it struggled to get all core overclocks at their stock max boosts, the reality is ryzen 2 is probably more similar than it is different. Looking at the TDP differences between the 3700x and the 3800x should provide some indication of this as well. There is a 60% tdp jump (65w->105w) moving between the 3700x and the 3800x, and the clock speed increases are 8% base and 2.3% boost. I know that TDP depends on lots of other factors like how long it stays at certain clocks, and how many cores actually achieve certain clockspeeds... but still. This should be a pretty good indication that the wall is not too far from 4.5ghz.
With all of that aside, I am extremely pleased with Ryzen 2, AMD brought a winner to the table and this is going to change the industry massively. I would just prefer that the garbage, tabloid-esque, tech reporting would be left on the curb where it belongs.
