Hello, @Stephan Ware !
What VM sizes are included in the Intel E5-2673 (Haswell) v3-based CPUs?
The Intel® Xeon® E5-2673 v3 2.4 GHz (Haswell) processors are found primarily in the general purpose and the compute optimized VM sizes (Av2, B-series, DV3 and DSv2-series, Dv3 and dsv3-series, Dv3 and Dsv2-series while the Ev3-series and Esv3-series have the Intel® Xeon® E5-2673 v4 2.3 GHz (Broadwell) processor). You can find a full list of VM sizes and their CPUs in the benchmark scores documentation.
For Intel E5-2673 (Haswell) v3-based CPUs, you would be looking at the specific sizes within B, D, F, and Fs series (a common size might be the Dv3 and Dsv3-series). You mentioned that you don't notice the account subscription name and subscription ID, which is likely why you aren't seeing anything in the portal. All Azure subscriptions have the ability to create a billing and subscription management support ticket, which you could use to track down an Azure account (with subscription name and ID) that you may have forgotten about.
Let me know if you run into any difficulties and I would be happy to help!
Edit:
Portal notifications do exist for some retirement announcements such as the Av1 size shown below however for the Intel® Xeon® E5-2673 v3 2.4 GHz (Haswell) retirement you would check your email for a notification. We've received feedback that portal notifications are a useful feature and that has been passed along to the product group. Thank you!
