Vapourware
According to SemiAccurate (https://www.semiaccurate.com/2018/11/12/intel-tries-to-pretend-they-have-5g-silicon-with-the-xmm-8160/) "Intel ... have not shown a single chip yet, anywhere, to anyone, working or not, only photoshopped fakes accompanied by analyst praise".
Seems like they think the XMM 8160 is pure vapourware
