We happened upon a processor that doesn't get much press but we see for sale in e-tail, so we did what any reasonable review site would do and strapped the Intel Core i9 9900KF CPU to our test bench.
Same with my 4790K I'm able to get into Windows at 5ghz but it never can run cinebench threaded.I have heard that many people have seen 5.1GHz out of these chips, but that obviously wasn't my experience here. This CPU can do 5.1GHz most of the time, but only in lightly threaded workloads or even gaming. When you push it, the result is the same as it is for the 9900K. It runs out of thermal headroom. This has been the case with all the latest Intel CPU's I've tested. The 9900K, KF, 9700K, and 10980XE are all that way. You can boot them up to 5.1, 5.2GHz, etc. and they'll POST, get into Windows and even do basic stuff.

It was a nice CPU, just couldn't live up to the hype. Had Intel not hyped up that 5.0 on air BS I think it would have been much better received. It’s still a very capable CPU today.That was a super disappointing CPU. Intel again promised a return 5.0GHz overclocks, but I can't recall any reviews actually achieving that. I'm sure there are outliers that might have been able to get that, but by in large those CPU's weren't the overclocking monsters Intel made them out to be.

I don't see mentioned in the review what cooling you were using.
Would custom water have helped?
Thanks for the review Dan! While not at a price-point match, I would like to have seen the AMD 3700X or even the 3800X in comparison to this one (Matches a core-to-core count). That's my only critique. Overall, great review as usual Dan!
Thanks for the 9900KFCpu review! It was finger lickin' good! I see no issue with Intel selling these "defective" chips for a little less. I'd consider it for myself if I was in the market. I was rooting for 5.1ghz stable or more, but the 5.0 isn't necessarily a deal breaker. Now if it couldn't hit 5.0ghz, then we'd have something to talk about. Looking forward to more cpu reviews.
