Thats insane! I wonder how the cooling works.

It's not that different from gaming AIOs. Personally I'm surprised they used water instead of heat pipes.

A lot of the high-end datacenter racks are getting water cooling now—you have a unit in the base of the rack that distributes water to all the servers above with a couple redundant pumps/PSUs.

Some systems are even water cooling random little components for completely fanless 1U/2U servers... I wonder about the longevity of those systems though!

With the water cooling, you can pipe all that water out to chillers and at a certain heat volume it makes more sense than handling all the heat in air exchangers.

The 9175F is kind of hilarious, it's just 16 cores but with 512MB of L3 cache between them. L3 cache is a per-chiplet resource so we can infer it has the same number of chiplets as the 128 core 512MB SKU, but 112 of the cores are disabled. Presumably that chip is aimed squarely at running software with per-core licensing as fast as possible with as few cores as possible.

Is it confirmed that it doesn't just include lots of dummy silicon for mechanical support, at least 16 working cores and the I/O die?

           AmpereOne     EPYC
  Kernel:        6.8     6.10

Wasn’t there sizable efficiency improvements just in the newer kernel that could explain some of this away?

Instead of buying 2 EPYC 4004 (4584PX) with marginally useless server features, I stuck 2 Ryzen 7000 (Ryzen 9 7950X3D) in uATX H13SAE-MF server boards with ECC RAM. They include IGPUs, but whatever. They work fine for load testing 100 and 400 GbE NICs.

For a value solution I'd take then an ASUS B650E/X670E mainboard (with PCIe 5.0 x16 and ECC support) for half the price.

But I'm not aware of a value 400 GbE NIC. Mellanox ConnectX-7 400G costs more than 3x the CPU.

ASUS B650E/X670E mainboard

No, no, no. Fuck ASUS and you don't understand the use-case.

I acquire gear through gray markets just fine because I'm not paying zillions for commercial channel parts. I can get a 1 port 400 GbE NIC for ~$1k USD. It maybe used or an engineering sample, but it works.
