Samsung has added a so-called "4nm" process to its roadmap:

At the annual Samsung Foundry Forum, Samsung announced its foundry's roadmap for the next few years, which includes an 18nm FD-SOI [(Fully Depleted – Silicon on Insulator)] generation targeting low-cost IoT chips as well as 8nm, 7nm, 6nm, 5nm, and even 4nm process generations.

[...] 7LPP (7nm Low Power Plus): 7LPP will be the first semiconductor process technology to use an EUV lithography solution. 250W of maximum EUV source power, which is the most important milestone for EUV insertion into high volume production, was developed by the collaborative efforts of Samsung and ASML. EUV lithography deployment will break the barriers of Moore's law scaling, paving the way for single nanometer semiconductor technology generations.

[...] The 4LPP process generation will be Samsung's first to use a "Gate All Around FET" (GAAFET) transistor structure, with Samsung's own implementation dubbed "Multi Bridge Channel FET" (MBCFET). The technology uses a "Nanosheet" device to overcome the physical limitations of the FinFET architecture.

But how many transistors per square millimeter is it?

    Intel has been beaten?
    Samsung made AMD-x86 or ARM.. in 4 nm. Maybe that would be something?

    Samsung already makes ARM SoCs: Exynos [wikipedia.org]. They're not a threat to Intel in terms of absolute performance, but when it comes to power efficiency ARM chips have been ahead of Intel for a long time.

      My point is that with processor manufactured in a 4 nm process those might perhaps beat Intel in speed and power efficiency?
      That the ARM architecture is more efficient than Intel is of course not news.
