Seems like IBM is really increasing its investment in open source software and hardware for PowerPC recently. I've noticed them offering bounties for PowerPC related work on Rust, there's this recent work on Mono, and OpenPOWER has led to the development of truly open servers and workstations like the Talos II.

They were also contributing to Swift on Linux and Go was ported to their platforms by them.

It does seem kind of odd though. The price/performance of PowerPC compared to Intel is still quite bad. To me it seems they’d be better off giving up on this term and focusing on other things. Maybe they could start with making Watson an actual thing instead of just a marketing term for consulting services.

Keep in mind that almost all that work will be Linux-based. This announcement was regarding AIX & i, which is off in la-la land compared to what you expect with a Linux-based system.

IBM people, if you're reading this and ported Mono to work with XCOFF, how about adding an XCOFF back-end to LLVM? Hell, I'd even take being able to bootstrap GCC 8 from source using your compiler.

Yes, price/performance for small systems is bad. But vertical scaling is relatively cheap/goes farther. If your database can't run in a cluster, you might need a very beefy machine to run it. That is what you use Power9 for.

I was never paid by IBM to do anything; this is a hobbyist endeavour.

The $1300 18-core / 72-thread Power9 seems like a good deal IMO. That's severely undercutting Intel's i9-7980XE (18-core / 36-thread), and offering grossly superior specs to boot, like wtf 90MB L3 cache, 8x DDR4 controllers, and dual-socket support.

In contrast, the i9-7980XE is MSRP of $2000, only has 4x DDR4 controllers and is single-socket only.

The 18-core Xeon Gold 6140 is $2400. Only 6x DDR4 controllers (although it seems to go up to quad-socket for what its worth).

AMD EPYC offers the single-socket 24c / 48t 7401p in and around $1300 (I'm seeing it ~$1100 and $1200). 8x DDR4, so its far more comparable to the Power9 machine. But Power9 is likely faster on a single-core basis, has a unified mesh instead of the 4x NUMA configuration of EPYC. EPYC doesn't have a unified L3 cache: tasks only effectively have 8MB of L3 (but there are lots of 8MB L3 caches scattered throughout EPYC).

So EPYC vs Power9 is a fair comparison at ~$1300, but Intel is severely overpriced in comparison. Actually, I'm not liking any of Intel's higher end options this generation, EPYC and Power9 seem superior on paper... as long as you don't need AVX-512.
