Was this intentional?

[mcu-administrator]

Yes. This particular stepping was not released to production.

A google search shows several users with:

"Intel(R) Core(TM) i9-9900K CPU @ 3.60GHz (family: 0x6, model: 0x9e, stepping: 0xc)"

A few look like posts and artifacts from developers that might be working in hardware enablement (reports from such developers using early-release rigs with QS processors are to be expected).

But some of the search results do look like forum posts from enthusiast end-users, etc.

There are quite a few models listed in the Update Guidance for SA-00270[1]:

Intel® CoreTM Processor i9-9980HK, 9880H Intel® CoreTM Processor i7-9850H, 9750HF Intel® CoreTM Processor i5-9400H, 9300H Intel® CoreTM Processor i9-9900K, i9-9900KF Intel® CoreTM Processor i7-9700K, i7-9700KF Intel® CoreTM Processor i5-9600K, i5-9600KF, i5-9400, i5-9400F

And one can grab the 0xc6 revision of the microcode (mentioned in the Update Guidance) at [2], for example:

$ iucode_tool -L cpu906EC_plat22_ver000000C6_2019-08-14_PRD_177C8996.bin microcode bundle 1: cpu906EC_plat22_ver000000C6_2019-08-14_PRD_177C8996.bin 001/001: sig 0x000906ec, pf_mask 0x22, 2019-08-14, rev 0x00c6, size 99328

But all that just adds work for distribution maintainers.

This is under investigation. We'll update as soon as we have an answer.

[mcu-administrator]

This has been resolved with microcode-20191113.

Thank you!
