Turbo clocks differ between products especially of different designs, they are not guaranteed and polling for accurate frequency via software is a joke. But oh no, people will still blow it out of proportion years later for profit, click bait etc.

It's more of a marketing issue that's present everywhere. They entice people to "max possible" while people delude themselves that it's "max guaranteed".

Intel out of the box doesn't do turbo clocks either on single core, or all cores, it falls all the way to base clock under heavy load but since most people never run such heavy loads they never see their stock Intel CPUs dropping down to 3.5GHz etc. and then complaining.

It's all being blown out with the only "wanna be proof" being done by software monitoring of clocks. Don't buy CPUs for their advertised possible numbers, buy them for the performance they offer and what you need. It's that simple.
Most of the PC builders who actually pay attention to clock speed have boards that enable MCE by default. Which means Intel users won't see the default base clock when under stress. I have my chip at stock and it runs at 4.2Ghz when under load not 3.6Ghz and I see 5Ghz boost in games often. AMD screwed up their Turbo and they fixed it.

is that what it was? i know the first bios for my b450m bazooka v2 allowed me to hit 4.4 on my 3600x, but the very next two limited it to just 4.2, i was wondering why.

Yeah well new AMD CPUs don't leave over 1GHz left untapped like not so old Intel CPUs. Even new Intel CPUs are not pushed to limit that well out of the box. Intel still has a way to improve their products. Where as AMD is using boost similar to what people are now more used to on modern GPUs, opportunistic boost based on various metrics, not a simple predefined static boost table like Intel. The old approach that left performance untouched was "good" for overclocking and made people "happy" they had something to play with and exploit, where as these newer GPUs/CPUs with much better boost algorithms leave close to nothing to exploit by OC ==> people are not as happy.

I've yet to see Intel platform motherboard with PL1/PL2/... set to it's proper TDP, say 95W instead of 4096W and 1024A current limit. Some did ship with MCE disabled, some. A 9900K run to absolute specs of it's TDP, no MCE, is not that fast and will throttle, turning into an overpriced 8700K like performance. So... reviewers don't care about specs much, slap it on, unlimit power, thermals, etc. and let it rip, often even with MCE on especially when their board enabled MCE on default, or their board pushed 101MHz BCLK and other sneaky OC.

The Turbo on AMD is not really screwed up, it's just impractical to monitor for 99.99% of people accurately for any verification of does it boost to max specs or not. They can tweak the algorithms and try please people with slightly higher boost here and there, and they have done that even though they didn't have to.
