  >Mindjárt tök olcsó lesz a 7nm,

  és megint felteszik a "szokásos" kérdést, hogy miért van "mindig" lemaradva az AMD?
  itt van már az 5nm -is ; lassan már a 3nm-ről cikkeznek és az AMD még a 7nm-et se hozta ki.

  "The company expects to reach full utilization on 7nm by Q3 2019, courtesy of increased orders from HiSilicon and AMD. HiSilicon is the fully owned subsidiary of Huawei and is responsible for designing the SoCs used in that company’s flagship devices. AMD has aggressively positioned itself for 7nm ramps in 2019. Its 7nm Radeon Instinct GPUs and Radeon VII cards are already in-market, while its Epyc and Ryzen CPU families will be refreshed on 7nm later this summer. A new 7nm GPU, based on AMD’s Navi family, is also expected."

  "TSMC has already begun volume production of its 7nm EUV node according to the same sources. The plan is to use EUV for contacts and vias at 7nm before wider usage of the technology at the 5nm node and below. Mass shipment of EUV chips isn’t expected before the end of the year and it isn’t yet clear which customers are using these products versus sticking with conventional EUV. Timing dictates that Radeon VII must be a first-generation EUV part. Our current understanding is that the upcoming Ryzen CPUs will also be first-generation EUV parts. It’s reasonable to think that AMD could deploy 7nm+ for whatever CPU follows 3rd generation Ryzen before swapping to 5nm when that node is suitable for mainstream big-core CPU manufacturing."

  Egyébként az új Threadripper-es procik már lehetnének 7nm+ -sak is. a TSMC a Q2-ben ráállt a gyártásra.
  Én még azt is elképzelhetőnek tartanám, hogy a tömegcsipekben a 7nm párosítva lesz egy 7nm+ -os chiplettel. ( vagy akár jövőre egy 5nm+ -al )

  A TSMC - befektetői negbészélésén elhangzottak alapján mindenesetre jövő év első félévére igérik az N5-öt tömegtermelésben.

  "Now I will talk about our 5-nanometer status. Our N5 technology development is well on track, with customer tapeout schedule for first half 2019 and volume production ramp in first half 2020. We are already in preparation for N5's ramp. All applications that are using 7-nanometer today will adopt 5-nanometer.
  In addition, we are expecting the customer product portfolio at N5 and see expanding addressable market opportunities. We expect more applications in HPC to adopt N5. Thus we are confident that N5 will also be a large and long-lasting node for TSMC.
  Now I will talk about the ramp-up of N7 and N7+. Our 7-nanometer has been a very steep and successful ramp in second half 2018 and
  we expect continued ramp through 2019. Our customer portfolio is growing stronger while more applications such as HPC and automotive are coming to N7 as well."
