AMD's 128-core Epycs could spell trouble for Ampere Computing

Sorry, but Zen 4c (like 9754) don't have the massive L3 cache or the fast clocking of Zen 4 (like 9684X). They're chopped down Zen 4's. 32 more cores is only good for hyperparallel HPC where the working set is smaller. That giant L3 cache and faster clock of Zen 4's is going to perform better in almost all other cases.

And Altra's are old PCIe gen 4 and DDR4, while AMDs are PCIe 5.0 and DDR5.

Aren't the AmpereOne CPUs already on the market? They were announced a bit over a year ago, offer PCIe 5.0 and DDR5, and were officially presented last month.

Vast majority of them will be used to just host a bunch of small VMs for customers. The "almost all other cases" are the minority of uses here

You do realise these Zen4c are aiming at HyperScaler for Cloud vCPU workload ?

Aren't web-frontends just basically HTTPS / AES-GCM cores that shuffles data between RAM and PCIe / Networking?

I'm thinking like Cloudflare or Twitter. There's not much compute going on at this level (all the compute would be at the SQL-server or Application-servers or other backend equipment handles).

What's needed for frongend / proxy code is AES for handling the HTTPS / TLS connection, and lots of threads to handle all the different connections.
