    > AMD ... a 24 magos sku

    nem tudom, hogy technikailag mennyire könnyű megvalósítani.
    vagyis, hogy 2 -nél több chipetet tud-e kezelni a desktopos io-die

    A ZEN4 3D V-cache -s verzió viszont talán már jövő év elején is kijöhet.
    én inkább erre fogadnék. Bár nem lesz olcsó ..

    a ZEN5 (8) + ZEN4D (16) - az pont 24 magos
    de csak egy generációval később jön.
    Ami furcsa lesz nekem, hogy míg az AVX-512 támogatást az AMD kiemeli majd ...
    az Intel meg gondban lesz ezzel
    ( letiltsa-e a Power magokban vagy engedélyezze )

    Agner ( cpu programozási guru) Alder Lake-es
    véleménye pár napja nagyot keringet a neten ..

    "It is very difficult to optimize the software execution for this hybrid system. A further complication is that a P core can run two threads in the same core so that each thread gets half of the resources. This is what Intel call hyperthreading. A program thread may run in three different configurations with different performance parameters:
    - Running alone in a P core with maximum performance
    - Sharing a P core with another thread, giving half the resources
    - Running in a low-power E core
    It is completely unrealistic that an application program can handle this situation in a reasonable manner and optimally allocate different threads to the different cores. Hardly any software application company can afford to make different versions of their code for every new microprocessor model and verify, maintain, and support all these versions. ....
    "

    "The way that Windows 11 handles this problem is still flawed, however. The system is giving high priority only to the thread that has the user focus. This ignores the behavior of many users. A user who is waiting for the computer to finish a heavy duty task is typically not just sitting and waiting. He/she is more likely to do something else during the waiting time, for example checking mails[2]. There are various technical options that the user can use to control the prioritization of threads, but it is unreasonable to require that the user understands and masters such options when the user's attention is on a complicated calculation task rather than on the hardware details of a specific computer. It is already quite difficult to optimize for hyperthreading, as I have argued before[7]. The hybrid design of the Alder Lake just makes the optimization an order of magnitide more complicated. It looks like the hardware designers have unrealistic expectations of how much software designs can be attuned to processor-specific peculiarities."

    ( + a Hacker News-os thread akit érdekel)

    persze ezzel majd az AMD-nak is meg kell küzdenie majd a ZEN5+ZEN4D-s kimérájával :-)

    mindenesetre a "8 mag feletti játékokra" !
    a homogén ZEN4 -magos gép talán szerencsésebb választás.
    ( persze az árak sok mindent felülirhatnak )
