I thought, and was pretty sure, that Intel had forced all of the motherboard manufacturers to remove those older BCLK enabled bios versions. I guess you must have found that through a shadier source, which is fine I guess.
The difference is, Intel is proud of their hardware and has been for a long time. They have been king of the hill for so long that at the time the Skylake CPUs came out they were not in a position to feel the need for more cores or not ready to implement architectures utilizing them.
Prices rarely have much to do with performance and everything to do with the impression of performance OR with consumer confidence in a given product because of the company track record. At the time that CPU was released to the market, the Ryzen CPUs were barely even being designed much less brought to market, so there WAS no competition at the time because AMD's only existing product lines were the A series and FX series processors, and neither of those could compete in any meaningful way, at all.
Now that AMD is beginning to push the envelope and offer some serious competition, at least in multithreaded performance, Intel is being forced to quickly get higher core count CPUs on the market so they can push back in that area. Single core performance is not as all encompassing as it used to be because more and more games and applications are being optimized to take advantage of those additional threads, and it is showing up in performance and benchmarking reviews AND in real world performance.
Also, the Ryzen CPUs are much newer than that Skylake CPU, so honestly, aside from those games or applications that rely heavily on strong single core performance, there really IS no advantage to that three generation old Intel architecture.
