    GlobalFoundries Introduces 12nm LP (Leading-Performance)

    https://www.globalfoundries.com/news...e-applications

    The new 12LP technology provides as much as a 15 percent improvement in circuit density and more than a 10 percent improvement in performance over 16/14nm FinFET solutions on the market today. This positions 12LP to be fully competitive with other 12nm FinFET foundry offerings. The technology leverages GF's expertise at Fab 8 in Saratoga County, N.Y., where its 14nm FinFET platform has been in high-volume production since early 2016.
    Also worth noting AMD confirms their roadmap has updated, 14nm+ products will come on 12nm LP.
    “We are pleased to extend our longstanding relationship with GLOBALFOUNDRIES as a lead customer for their new 12LP technology,” said Mark Papermaster, CTO and senior vice president of technology and engineering, AMD. “Our deep collaboration with GF has helped AMD bring a set of leadership high-performance products to market in 2017 using 14nm FinFET technology. We plan to introduce new client and graphics products based on GF’s 12nm process technology in 2018 as a part of our focus on accelerating our product and technology momentum.”

    A HP node, finally.

    It's not a real HP node, it's 14nm+. Not a bad thing, but don't buy into the hype.

    just something to make Volta's 12nm not sound like a tech advantage.

    Which, it isn't really... (given it seems to just be 16+/++ with a bigger reticle limit)
    -Q

    Yeah, a marketing rebrand to deal with the competitor's marketing rebrand.

    Tweaked 14nm (for the 10% increased clocks) with a few more 14nm layers (leading to 15% increased density) I guess.

    Regardless, confirmation of 12nm 2018 CPU/APU/GPU products from AMD.

    Not according to Anandtech, don't ask me why but they say same 13 metal layers but 7.5T design library instead of 9T
    The new 12LP relies on the groundwork set by the 14LPP, but uses 7.5T libraries, which is one of the ways that enables GlobalFoundries to shrink die sizes by increasing transistor density. Since the library contains different elements, IC developers have to “recompile” their designs to take advantage of the process.

    let's wait and see.

    *cough* *cough*

    14LPP+ and 14HPP both fit the most likely profile for 12LP. As both improve performance... the 7.5T + the 30% perf improvement isn't bad. (30% if it used 9T, 7.5T makes the 10%perf~15%power pretty accurate.)

    Why are you spreading misinformation or passing off wild speculation as factual information ?

    https://www.globalfoundries.com/news...e-applications

    "The new 12LP technology provides as much as a 15 percent improvement in circuit density and more than a 10 percent improvement in performance over 16/14nm FinFET solutions on the market today."

    "The new 12LP relies on the groundwork set by the 14LPP, but uses 7.5T libraries, which is one of the ways that enables GlobalFoundries to shrink die sizes by increasing transistor density. Since the library contains different elements, IC developers have to “recompile” their designs to take advantage of the process. Meanwhile, since the 12LP and the 14LPP are very similar, for GlobalFoundries’ existing customers migration path to the 12LP is pretty straightforward"

    GF 12LP allows you to design a high performance chip using 7.5T libraries and still gain >10% perf or freq at same power over a similar complexity design at 14LPP using 9T libraries. There is no indication of 9T libraries available at 12LP or further performance gains from statements made by GF.

    10 % increase in performance at the same power is pretty substantial

    Indeed, it keeps AMD competitive with whatever 14+++ from Intel can do next year.

    It takes the 1800X at 3600/4000/4100 to a 2800X at 4000/4400/4500

    That's before any potential "Zen+" IPC improvements (I don't see AMD standing still on the Zen core here, it might not be Zen 2 but it will surely have some tweaks).

    It's good that they got 10% performance despite the 7.5T usage instead of 9T (my understanding is the opposite usually occurs? Process maturity?).
