Yeah that 5.3 GHz is ST only. I was speculating about whether more than 2 cores could boost to 5.1 GHz or even 5.0 GHz in PL2. Which I'm thinking would be possible with sufficient cooling.
For Comet Lake? 300+W PL2 is rumoured, and this is stock I'm talking about.As far as the power consumption(excessive) goes that only matters if you overclock correct? If you use stock settings and use something like a Noctua d15 everything should be ok?
I guess it shouldn't be called stock even if it's default on many boards. Some more enforcement by Intel would be nice, but it's not in their interest...I have to assume most Z490 boards will be ~250W PL2/Infinite Tau.

I think that Zen3 L3$ size will be more important than the unified L3$ (basically, this is extending the 4 core CCX to 8 cores). With the right topology, composite core access latency will decrease, but I wouldn't expect significant changes in FPS.Can't wait to see what an unified L3 (for Zen 3 if it's true) does in gaming
So repeat after me: there is no such thing as stock 300W PL2.

which let's face it is really the main if not only reason anyways you'd be buying Comet Lake over Zen 3
No, it's not stock, and you're passing a very dangerous threshold. Remember the blade always cuts both ways: just because a couple of X470 motherboards were loose cannons by default in terms of boost limits does it mean that stock TDP for 2700X was 150W?! Yeah, I didn't think so either. According to your statement the stock Intel and AMD settings are dictated by the maximum value that any of the OEMs is willing to put on their high-end motherbaords. So stock value may be limited to 1 product only, and it may also change in time should some hot-shot motherboard launch later.It's stock if the mobo OEM makes it stock. Intel can disagree all it wants.
I am not confident that Comet Lake-S will be a faster gaming processor than the 9900k or 9900ks. As such, I do not think it will be faster than Zen3 either.

While PL1 can be sustained forever (as long as cooling is not an issue), the PL2 limit can only be sustained for a finite amount of time in stock configuration, and that time is given by PL1 Tau. The hardware default for PL1 Tau in the table above is 8 seconds. It can be higher than that, like 30 or 60 seconds, but it still needs to be finite and relatively short.
The 30-60s were example values. (as opposed to the "infinite" value some mobo manufacturers are keen to set on their Z boards to "help" consumers)I do read a hardware default of 1s and a maximum of 8s in the table for PL1 Tau. Where did you get your numbers from?

Well, that makes total sense for an OEM system - especially power limited systems like mobile. It’s a different situation with enthusiast class systems - where grabbing the top slots in performance reviews drives excitement and thus sales. So things like default enabled MCE became a thing. Review sites also run demands use case scenarios like fully threaded and saturated AVX workloads - an those produce those extreme power loads; something a gamer is never going to see.The 30-60s were example values.

A token real-life figure is the 28s value used for many of their mobile SKU implementations.
Ryzen 3000 series is Zen 2.? 9900k is already faster than Zen 3 (by a very small margin) in games. AMD still haven't beaten Intel's 14nm when it comes to pure gaming yet. Of course the Intel part uses more power, which many are okay with.

I should have pointed to the problem of motherboard 'review samples' having had MCE enabled by default from some suppliers (like ASUS). IIRC, this was with early 9900k reviews, but I’m not sure. Reviewer, obviously, caught on - so I wouldn't expect it to be an issue with comet lake. The problem is that Comet Lake will be branded as a 250W CPU (or whatever) based solely on max power usage with an all core AVX workload. That’s just the way the tech media, and these forums work. Obviously, anyone wanting to overclock the 10900k will need custom water (the best AIOs are only marginally better than a D15).I don't think most boards enable MCE by default, that causes overvolting. This is just power draw being allowed to go to as high as it needs to without breaking the stock multiplier limits. I could see MCE being enabled would cause the 10900K to draw 300 W.
You will for sure want a 200+ W rated cooler for the 10900K.
Ryzen 3000 series is Zen 2.
