  válasz Abu85 #14142 üzenetére

  Jim Keller visszatérése kapcsán olvasgattam kicsit egy két nyilatkozatában érdekes részleteket hintett el.

  1. AMD következő x86-os megoldásáról:
  They will be closer in frequency to the 4 GHz of AMD's latest Kaveri x86 SoC than today's 2 GHz ARM chips, he said. For Skybridge, AMD tweaked its new Puma x86 cores to look more like an ARM V8 core.

  AMD upgraded its current on-chip fabric, I/O and memory-management units so they could accommodate either the Puma+ or standard ARM cores in Skybridge. The fabric gets an upgrade for the custom ARM cores coming in 2016, probably made in a 16/14nm FinFET process.

  "We got the IP, SoC and fabric right, then worked on how to plug the cores into them," he said. Skybridge provided an opportunity to "get the [SoC] plumbing right," he added.

  Keller suggested AMD will consolidate its work on separate Bulldozer and Jaguar x86 cores into one processor line in the future. Meanwhile, the team had to bring up new verification and design flows for ARM SoCs.

  Much of the architectural work on the upcoming AMD chips is done and the company is well along in implementing them, Keller suggested. AMD is apparently already well along in the custom designs that will use a 16/14nm FinFET process that he said "looks pretty good, we're happy with it."

  2. Gyártástechnológia kapcsán:
  Keller considers largely solved the issues dealing with multiple-patterning lithography required for the 14/16nm processes in which his team is designing the first K12 chips. Just adding on more metal layers is no longer an option, but "we have other proprietary tricks," he said.

  For the 14/16nm process, his team had to scale challenges with the vertical FinFET transistors it uses. He notes of all the parts of his team, the design for manufacturing and test groups have grown the most over the years.

  Itt netán már az utolsó (D) árbára célzott?
  
  A. PD-SOI pl. AMD Phenom II/Llano
  B. FD-SOI pl. ST mintachipje
  C. FinFET Bulk pl. Intel Ivy/Haswell (bár a 3D Tri-Gate így néz ki náluk)
  D. Vertical FET Bulk

  Esetleg ha így jobban tetszik:
  

  Vagy ne rohanjunk annyira előre és "csak" az Inteléhez hasonló finFET kialakításnál a silicon fin okozott némi gondot?
