Before anyone wants to point out that Optane is better for random read / write, do also show me 8 Tb of Optane storage.

8 Gb for $7000 also, $200 per extra 8 Gb, and soldered to prevent user upgrades.

I don’t think that Intel or AMD need to worry at all about the new Apple laptops.

My 10900K could do 4533CL15 / 4600CL16 with 1.28v SA. Completely safe and effortless, 10th gen still remains the strongest Intel IMC to this date for 1:1 memory clocks.

Also 4000 is nothing for 10th gen.
