If these conversations happened as Anandtech suggests in this writeup, then Anandtech was pretty ballsy.
The Intel representative did confirm the CPU was overclocked. We were told that on stage the presenter was actually meant to clarify that the system was overclocked, however the specific wording was not stated as it had been prepared.
Intel confirmed that a water chiller was used, which we saw in our system demo examination the day after the presentation. We were told that it was not intended to showcase the cooling on the stage due to time constraints, to which we responded that Intel’s implementation of pre-overclocked systems in the past are typically accompainied a discussion on the pre-overclocked nature and the cooling used in the past, yet this presentation did not have this.
and it's a 14nm part:
The only item that Intel would confirm here is that the 28-core processor is built on one of its 14nm nodes. For anyone thinking it was a 10nm node, this confirms that it was not, however it does not say much more; Intel is purposefully keeping its cards close to its chest on this one. The smart money seems to be that the chip is likely to at least be based on the Skylake-X processors, like the 28-core Xeon Platinum 8176 or Xeon Platinum 8180, rather than the future Cascade Lake platform, however Intel has also promised that the consumer version of Cascade Lake-X will be coming by the end of the year.
Purposefully not making a lot of commentary here. Anandtech's pointed questions basically stand on their own.
