#Here's where it get's funky
#Bit 5 - 0 (10 1111 = Dec 47) I'm not sure how to interpret that. Clearly used to enable memory encryption.
#Bit 6 - 11 ( 001 01 = Dec 5) Reduction of physical address space in bits.

Read them, unfortunately I can't give any insights - my understanding seems to be at the exact same level as yours. I do have a feeling that the example in the pdf mentioning reduction from 48 bits of address space to 43 bits, using up bits 43 : 47, does coincide nicely with the numbers in your EBX register... but it is now to late at night to be trusting my gut.
you probably wont be able to get as high clock speed and overclocks on a server board as with a tr4 board. made to be cheap and reliable not fancy with zero regards to overclocking.
This is exciting for me. Very exciting. not only because of the disruptions that this platform will provide, but also the amount of cheap thread ripper/epyc could 5 years from now on the used market. Even in the upcoming years I can foresee tonnes of Intel machines sold off for cheap.
I’m amazed to see so much interconnectivity and power being packed into such a small system
What about adoption? This cpu clearly wins, but how many businesses will run out and buy a bunch of replacement machines with epyc/TR? anyone in the enterprise sectors know how this would play out?
With all the stuff that happened in Florida and Texas and such, I suspect the timing of these systems is good for the businesses who lost a bunch of hardware. It’s probably a good time to drive adoption of this. Hopefully nothing bad happened to the folks there, but if you’re a sysadmin or part of the higher ups, you know what must be done
This is mostly distributors. I’m working with supermicro to populate a datacenter with EPYC and it seems like they’re dragging their feet. I wonder if they didn’t get enough time to get their systems designed and tested.
