AMD Demonstrates Stacked 3D V-Cache Technology: 192 MB at 2 TB/SEC

Good server CPUs should survive 7 years of use without problems.

Nevertheless, their expected lifetime is not much greater than that.

I normally replace CPUs because they become obsolete much earlier than they should show age problems.

Nevertheless, I had a pair of Opterons that were used continuously for about 10 years.

At the end, they developed a very high leakage current, leading to an idle power consumption several times higher than in the beginning.

Increased leakage current is one of the most frequent signs of aging in semiconductor integrated circuits.

How do you assess that increased consumption?

Server BMCs provide power consumption timelines, which are measured in real time by the PSUs themselves. Also processors can assess their power consumption and report it to the OS and to the platform.

Querying and recording these as time series provides very nice insights over time.

Nice I'll look into that, I log those but never looked at them
