       | adjusting into it since compared to Zen 4 SKUs, SPR seems like a
       | horrible design that won't scale well (and doesn't according to
       | pretty much all benchmarks).
       | 
       | AMD can simply make a smaller core and release a new CPU with 128
       | cores (Zen 4C -- higher density core clusters consisting of
       | smaller Zen 4 cores [with less L3 than a normal one]). On the
       | other hand, for nearly every Intel CPU it is a whole new
       | design/engineering mess.
       | 
       | I hope they don't fall to behind on this, otherwise we might see
       | yet another monopoly (e.g. AMD not releasing a consumer grade
       | Threadripper is the first indication that they kind of feel safe
       | on this side since even their multiple years old SKUs offer far
       | more value brand-new SPRs).

         | that Granite Rapids is moving to a slightly different layout
         | with I/O dies bookending 2-3 compute dies. Ultimately AMD's
         | chiplet architecture is cheaper, simpler, and faster for almost
         | every app though.

       | interesting than the core CPU story.

       | on eBay for 100$ back in September 2021!
