    persze most látom, hogy az Anandtech-es LisaSu-s >$300 chiplet cikkben
    a szubsztrát is meg van említve..

    "One of the issues here is that a chiplet design requires additional packaging steps. The silicon from which these processors are made have to sit in a PCB or substrate, and depending on what you want to do with the substrate can influence its cost. Chiplet designs require high speed connections between chiplets, as well as power and communications to the rest of the system. The act of putting the chiplets on a singular substrate also has an effective cost, requiring accuracy - even if 99% accurate placement per chiplet on a substrate means a 3 chiplet product as a 3% yield loss from packaging, raising costs. Beyond this, AMD has to ship its 14nm dies for its products from New York to Asia first, to package them with the TSMC compute dies, before shipping the final product around the world. That might be reduced in future, as AMD is set to make its next-generation chiplet designs all within Asia."
    ...
    "But for now it seems, AMD’s way to address the sub-$300 market is going to be with either last generation hardware, or monolithic silicon."

    persze Lis Su - optimists .. megoldják a problémákat ..
    és majd "valamikor" látunk chipleteket a "lower-end/tesco gazdaságos" piacon is ..
    persze ehhez szerintem még sokat kell aludni ..
    "Dr. Su ending on a happy note that at the right time,
    you’ll see chiplets at the lower end of the market."

    spekuláció:

    régebben[1] talán ~ $10 lehetett egy chipletes AM4-es proci gyártásában a szubsztrát költség ; selejttel talán max ~$13 ...
    Viszont most a szabad piacon valószínüleg már 5x; 10x árat is kérhetnek
    az elérhető szabad kapacitásért...
    vagyis akár +$100 -ral is növekedhet egy AM4-es chipletes termék önköltségi ára.,
    [1] "The cost of ABF substrate, usually quoted per chip, starts at about 50 cents a chip and tops $20 for premium server CPUs." (forbes)
