I could be wrong here, but it seems like Intel is trying to get as many processors out there as they can before independent reviews. I find it hard to believe that Mindfactory in this world economy would risk the ire of Intel, risk their supply chain and sell these processors two weeks before their official launch without Intel's permission. I was already trying to wrap my mind around Intel officially releasing Rocket Lake two weeks ahead of their review embargo lifting... Intel for awhile now has been trying to sell the idea that benchmarks are not important anymore (but only once they fell behind AMD's Ryzen in benchmarks) and now they seem to be trying to convince people that reviews aren't important anymore either. Just buy it because we say its great and you should blindly trust us seems to be their new marketing...
From what I have seen of the benchmarks of these retail processors prematurely sold they are not overly impressive. Yes they have improved in single core compared to their own offerings, but they won't have a skew above 8 cores and they are still behind AMD's Zen IPC. Most single core scores I've seen for the 5800X put the processor at 630 and above single core in Cinebench R20. I know pure stock my 5900X scores 636 single core CB R20, and with a few slight tweaks I have it boosting to 4.99Ghz and 5.024Ghz on its two best cores of each CCD and it improved the score to 650. It is still early, and I could be wrong but with this being a new core design I don't think Intel is going to be getting much more overclocking potential than ~ 5Ghz for the 11700K and I think they already pushed the 11900K as far as it can go at 5.3Ghz single core. If that is the case then the 5800X will maintain a lead over the 11700K and the 11900K will be very close to the single core performance of the 5900X.
From what I have seen the 11900K is going to be retailing for $600, which is $50 more than the MSRP of the 5900X. That is going to be hard to justify if its single core performance is nearly the same but it gets absolutely destroyed in multi-core oriented tasks. Yes, the 5900X isn't easy to find right now and scalpers are asking a huge mark up for them, but they can still be found at MSRP. It just seems to me that Intel is taking advantage of supply issues and once again price gouging.
