The Power9 should be more performant than EPYC/ThreadRipper and CAPI gives you higher memory bandwidth to a GPU.
Are there any benchmarks that I can look at for this?

Just curious, what do you use OpenBSD on macppc for, and which version? Debian PowerPC version has a few bugs but at least the desktop package selection has been decent, shame that the port lost the official status.
I have a PowerBook G4 that was at one point a daily driver, plus an eMac that was running at one point but needs a new hard drive; those were/are both in desktop roles. I also have a Power Mac G5 and an XServe G5 in server roles. All of them have OpenBSD 5.9 installed (except the eMac, which had OpenBSD 6.0 installed before the hard drive failed). The XServe and Power Mac are in storage right now, but I'd like to get…
Only 4 core CPUs, a tad disappointing.

What is their performance?
IIRC they're a bit better than an Intel core on a single threaded load with some variance depending on the workload. But going from 1 to 2 threads per core increases the Power 9's throughput by 80% instead of the 20% you expect with an Intel core. And you can go up to 8 threads per core for something like 120% the total throughput of 1 thread. All those numbers for threads per core are also highly workload dependent.…
Talos™ II drives the state of the art of secure computing forward. Talos™ II gives you — and only you — full control of your machine's security. Rest assured knowing that only your authorized software and firmware are running via POWER9's secure boot features. Don't trust us? Look at the secure boot sources yourself — and modify them as you wish. That's the power of Talos™ II. That is fkin nice to be honest. There is…

They're already scaling down … in the POWER8 Talos campaign, the cheapest CPU option was something like $1300, the CPU they're offering here is only $300. And the board, because you don't need expensive memory buffer chips anymore, is almost half the price as then.
Yeah previously it was over $4,000 for the board and CPU, this is nearly half the price. If they can keep this up, I could actually fork over the money for the 3rd gen.
Oh wait, wrong company.

No idea recently, but even back in the apple PPC days pretty much everything worked. The things that didn't were typically lesser used desktoppy things or more community written software that didn't take endianness into consideration. If you're not afraid to dig into sources alot of things only took adding an endianness hack / byteswap to certain lines to make things work properly. Also to check into are some languag…
Most Linux work for modern POWER seems to be for the ppc64le target, which runs the CPU in little endian mode. That being said, there's probably a lot of libraries with x86-64 ASM kernels in them which will run slower if they have to use the generic C/whatever version on power.

6.1 for macppc doesn't ship with any web browsers except for text-based and Netsurf sadly. It struggled on my 1Ghz iBook speed wise too. I am going to give it a fresh look on a DP 1Ghz Quicksilver too.

That price does not include RAM or a GPU. Even a bare bones motherboard costs more than $2,000. I have no doubt this an awesome machine, but that price puts it outside my budget range. :(
That's par for the course for a workstation. Actually on the affordable end, which is surprising given that it's using POWER9 which I figured would be expensive (by virtue of not being x86).
Compared to the RISC based propietary Unix workstations of 20 years ago, the price is really good.
At work, our CAD people have machines that are in the € 1,000 - € 1,500 price range. Those machines are fairly big and powerful, at least compared to our regular desktop PCs.
It is possible to spend more money on a workstation, if one wants or needs to, and get a more powerful machine. Far more.
Depending on your use case, our CAD machines might be lightweights. But the amount of computing power you can get for € 1,000-1,500 these days is insane compared to the landscape 20 or even 10 years ago.
I am certain the Talos II offers good performance for its price. My point was that I would like to have a machine that comes without any opaque blobs or "management engine", but I am not going to spend that much money on it. I'd be happy go get such a machine in the € 500-1,000 price range at correspondingly lower performance.

It is; the question is, can you put the 24-core chips from IBM in the same socket? For that matter, what on earth is the socket name for POWER9 (or POWER8)?
