According to this, Samsung and TSMC are ahead of Intel, since these two have shipped their “10nm” chips which are ahead of Intel’s top-of-the-line shipped chips in transistor density. When/if Intel ships their 10nm chips, however, the leader position in transistor density would be regained by Intel (by around a factor of two!). Unless TSMC/Samsung manage to squeeze out something better than their current tech before then.
