    Architektúrák kapcsán érdekes lehet az Anandtech elemzése az új konzolok háttér-tárólójáról.

    pl Spéci I/O compression unittal
    - a PS5-nél 9 ZEN2 CPU mag
    - az XBOX X-nél 5 ZEN2 CPU mag ..
    feladatát helyettesítették.

    Enterprise vonalon is lenne valami hasonlónak értelme,
    amit akár az EPYC 4 / 5 .. "I/O Die"-ba is kerülhetne
    pl. egy szabványos adattömörítési támogatással
    Egy amolyan optane memória szerűséget .. tömörítéssel , gyors ki és belapozással .. hasonlóan mint az újgenerációs konzoloknál.

    Ami érdekes, hogy a Microsoft konzol vonaláról pár API-t portolnak majd a szabvány windows -ra is, szóval valami lesz :)
    "The most interesting bit about DirectStorage is that Microsoft plans to bring it to Windows, so the new API cannot be relying on any custom hardware and it has to be something that would work on top of a regular NTFS filesystem. Based on our experiences testing fast SSDs under Windows, they could certainly use a lower-overhead storage API, and it would be applicable to far more than just video games."

    egy szép ábra .. a PS5 Custom I/O-ról.

    "Cache Coherency

    The last somewhat storage-related hardware feature Sony has disclosed is a set of cache coherency engines. The CPU and GPU on the PS5 SoC share the same 16 GB of RAM, which eliminates the step of copying assets from main RAM to VRAM after they're loaded from the SSD and decompressed. But to get the most benefit from the shared pool of memory, the hardware has to ensure cache coherency not just between the several CPU cores, but also with the GPU's various caches. That's all normal for an APU, but what's novel with the PS5 is that the IO complex also participates. When new graphics assets are loaded into memory through the IO complex and overwrite older assets, it sends cache invalidation signals to any relevant caches—to discard only the stale data, rather than flush the entire GPU caches."
