Hello.
Does anyone please have a clue if all Coffee Lake refresh processors have fixes for Meltdown and/or Spectre? This article at Anandtech suggest CFL-R has a hardware fix for meltdown (variant 3) and for variant 5:
Intel’s New Core and Xeon W-3175X Processors: Spectre and Meltdown Security Update
The Core i7-9900K, i7-9700K and i5-9600K launched last year are all based on P0 stepping according to ARK database - Products formerly Coffee Lake (select appropriate processor and then "Ordering and Compliance" on the left).
Actually all the new processors are based on P0 except i5-9400F, which is listed as using U0, likely the same U0 as in case of non-refresh Coffee Lake (such as i5-8600K), and i3-9350KF, where the information is missing completely.
Does this mean some of the new processors are not fixed? Maybe only CPUs based on 8-core silicon have fixes? I am looking for some new i3 processors because of ECC and low TDP but meltdown fix is essential as my workloads are I/O heavy.
Thank you.
