Thanks for your info but about 7 nm nodes TSMC according to their website NOT ACCORDING TO ME has divided the 7nm segment into 2 divisions and on their website it specifically says one for mobile phones and the other for high computing power chips before that they have not divided this into 2 segments, may be these high computing power chips are for some other use also rather than only ASIC MINERS
When TSMC is talking about high performance they have e.g. GPUs in mind. NVIDIA and former ATI (now AMD) are TSMC customers. There are lots of high performance networking product e.g. from Broadcom or Qualcom too.
In principle it is everything, which is not battery powered and needs maximum compute performance.
