    Apologies for the late megathread - most of us (the moderators) are busy. The removed thread remained unlocked if you want to continue to discuss in those threads.

    Edit: This thread will not be separated into written/video review due to the limited amount of reviews available compare to TR3 - please refer to Videocardz's list for details

    What is the purpose of the metal frame around many bare-die chip packages?

    Posted: 25 Nov 2019 10:54 PM PST

    I've noticed for quite a while that with many microprocessors where the bare silicon die is exposed, there is often a metal frame around the package. Notable examples include some Intel Core M SKUs, most graphics card GPUs, the CPU on the Xbox One X, AMD's embedded EPYC processors, and the Intel Lakefield concept apparently has two of these frames. It seems to be a very popular design element of bare-die chips. It honestly looks like the base of an integrated heat spreader, but it doesn't cover the die.

    What is this frame for? Is it to prevent the heat sink from applying too much pressure to the chip? Some kind of structural rigidity? Some electrical function?

    How does Intel's "Foveros" chip stacking technology work and what are its benefits and drawbacks.

    Posted: 25 Nov 2019 05:30 PM PST

    How does Intel's new "Foveros" chip stacking technology work, and what are the advantages and disadvantages, and use cases? Is it just space savings they're after? Is it better or worse than 2d chiplets in terms of cost or yield, efficiency or performance?

    It also looks from the press releases that they plan on only having two layers (not including the integrated DRAM), with the bottom serving as both the interposer and space for cache and lower power chip components. You'd think that having a combined interposer and auxiliary chip IPs the size of the package itself wouldn't be great for yields or flexibility, especially if they want larger desktop, workstation and server/enterprise chips with this technology, so why not have two stacks of chiplets, one on top (for the CPUs, GPUs and any high power ASICs) and one interfacing with the package (with separate chiplets for cache and auxiliary processing) with an interposer in between? That way only the interposer is the size of the package, which I assume is much easier to manufacture right than a processor.

    Hi there, I am interested in how Intel is going to sail this storm. If you were the boss in Intel, what things are you going to do now?
