Intel Core i7-9700K Overclocked to 5.5 GHz on Water, Cinebenched
Intel's upcoming Core i7-9700K processor is the first Core i7 SKU to lack HyperThreading, but that isn't stopping the chip with 8 physical cores from edging past its predecessor posting strong multi-threaded performance. Chinese publication ZOL managed to overclock the chip to 5.50 GHz under liquid cooling with all its cores enabled, by simply dialing up the unlocked multiplier to 55.0X, and a rather high 1.535V core voltage.
The overclocked i7-9700K was put through Cinebench R15, where it scored 250 points in the single-threaded test, and 1827 points in the multi-threaded one, a 7.31x multiprocessing ratio. A current-generation 6-core/12-thread Core i7-8700K typically manages around 1550 points at stock speeds (at least 4.30 GHz all-core Turbo Boost frequency), in the multi-threaded test. The i7-9700K could hence be less ahead of its predecessor than hoped. It's the 8-core/16-thread Core i9-9900K, which could grab enthusiasts' attention (and monies).

This 5.5Ghz is a nice POC OC, showing temperature is more controllable with the new STIM.
hit jobPR spin from Intel, we've seen this with 4790k, 5775c, 7700k, 8700k.What Intel won't tell you, obviously, is that only a handful of these chips will ever get close to 5.5GHz even with exotic cooling :rolleyes:
What AMD needs to do now is release CPU with 2 full CCX units (8 cores), no HT and clock it higher. This seperation of gaming and productivity CPU's is smart on Intel's part. Games always need higher clocks. So, tweak gaming grade CPU's to deliver that. Productivity feels comfy with lower clocks but many threads. Obviously, it's hard to achieve both on same CPU.
What is next? You need 32 cores to play WoW!
Unfortunately, while the 2700x is a very good chip it is out-haloed by this i9 just because of intel's advantage in IPC per core. That said power draw is of course better for the AMD stuff, but if you know history you will know that AMD sticking to a cheaper, inferior product just will not work. Ryzen sold so well early on because it was better than anything intel offered, now a lot of people will probably just go back to the same perception that AMD's products are cheap, second class things so people with more money than time to read reviews will just snatch up the intel stuff and pay whatever they get asked.
When the olympic silver medalist finishes 0.1 seconds behind the gold, no one can even remember the silver medal winner's name a month later. That's an amazing accomplishment, but folks will remeber who won the Gold as, if for nothing else, his name and picture are on the Wheaties Box. The problem is, for the tasks that PCs are far and away most used, Intel has the edge. It's not a big edge .... but the result has not been good for AMD which had 10.7% more market share in Q3 2017 (22.30%) then they do now in Q3 2018 (20.15%)
