  Remélem a CES 2019 -en már az 5nm-es tervekről is szó esik.
  N7+ vagy N5 ?
  mit döntenek az AMD-nél ?

  TSMC to Start 5nm Production in April

  "SAN JOSE, Calif. — TSMC taped out its first chip in a process making limited use of extreme ultraviolet lithography and will start risk production in April on a 5-nm node with full EUV. Separately, the foundry forged partnerships with four partners to support online services for back-end chip design.

  ...
  TSMC said that N5 will deliver 14.7% to 17.7% speed gains and 1.8 to 1.86 area shrinks based on tests with Arm A72 cores. The N7+ node can deliver 6% to 12% less power and 20% better density; however, TSMC did not mention speed gains.

  Chip designs for the N5 node can start today, although most EDA tools won’t hit a 0.9-version readiness until November. Many of TSMC’s foundation IP blocks are ready for N5, but some, including PCIe Gen 4 and USB 3.1, may not be ready until June.

  The N7+ node sports a tighter metal pitch and includes a single-fin library that can help lower dynamic power. It will be available in a version for automotive designs by April. N7+ offers “nearly the same analog performance as N7,” said Cliff Hou, vice president of technology development at TSMC.

  Transistor density at N7 is 16.8x greater than at the foundry’s 40-nm node, said TSMC. Unfortunately, costs are increasing, too. One source pegged total costs for an N5 design including labor and licensing at $200 to $250 million, up from $150 million for a 7-nm chip today, limiting pursuit of Moore’s Law to the well-heeled.
