Jesus christ son, could you have your tongue any further up Intels rear end? hahaha
Make no mistake, the 9900K will be a really good chip, Intel has been forced to do this by AMD, especially given they know whats coming with 7nm, they'll get *a lot* of people to switch across and are probably hoping for another 2500k moment where people sit on that same chip until something really remarkable from Intel comes along. That sounds counter intuative, as you will say "Why will intel not want to compete and will be happy to let users not buy more of their products?" well, Intel probably realise themselves the only way they can beat AMD going forwards is with a node shrink and give that 10nm is giving them all sorts of issues, and they will probably need a few refinements before 10nm surpasses 14nm++++++++++ it will be a case of make hay while the sun shines.
Not to mention people buying the 9900k will likely not upgrade again for a good few years, so you may aswell capture as many people now willing to upgrade as they are not likely to do so again for a few years...
Its a really smart move from Intel, they are basically playing their ace up their sleeve, its a bit of a gamble but it should pay off for them. Bring out a cracking 8/16 that makes the competitions look massively weak in comparison, but they know AMD has their refined version coming, im guessing Intel think or hope AMD wont get near that performance with the first iteration of 7nm.
