IBM Power 9
Power 9 is the IBM Power processor generation before Power 10, available from 20 March 2018 in the scale-out S914, S922 and S924 models that IBM i supports. For AI it falls one generation short: on-chip Matrix Math Acceleration starts with Power 10, the Spyre accelerator card is a Power 11 option, and IBM states that IBM i 7.6 is not supported on Power9 and earlier processor technology, which caps a Power 9 at IBM i 7.5.
What is IBM Power 9?
Power 9 is a processor, not a model name. It is the chip inside a batch of IBM Power servers sold from 2018, and IBM i runs on several of them. IBM announced the smaller Power 9 servers on 13 February 2018 in hardware announcement 118-023. IBM's own lifecycle page says the Power S914 became generally available on 20 March 2018. The big enterprise machine, the Power E980, followed on 21 September 2018.
Think of a Power 9 box as a 2018 truck. It still starts, it still hauls the load, and it was a strong truck when it was new. The catch is that the factory added the tow package in the next model year. You cannot bolt it on later. For AI, the tow package is the matrix math unit inside the chip, and Power 9 was built before it existed.

Every date here is from IBM's own withdrawal notification pages for machine types 9009-41A, 9009-42A and 9080-M9S on ibm.com/support, read on 16 October 2026.
Can a Power 9 run AI work for IBM i?
Not on the chip itself. Matrix Math Acceleration, the math unit that makes AI inferencing quick on a Power processor, starts with Power 10. IBM's Power 10 tutorial says Power 10 provides four of those engines per core. The same IBM page puts a number on the gap, using Power 9 as the baseline.
IBM's own inferencing comparison, single precision model
IBM writes: "we have demonstrated a 5x throughput advantage on Power10 relative to Power9" for large single precision floating point inferencing models, and adds that lower precision types are expected to see even higher speedups. That is one IBM demonstration on one model, not a promise for your workload.
This is about where the AI math runs, not about whether your programs work. A Power 9 can still send a question to a model that runs somewhere else, such as a cloud service, and act on the answer. What it cannot do is run the heavy inferencing fast on its own cores.
Can you add an AI card to a Power 9?
No. IBM's add-on inferencing card is the Spyre Accelerator, and IBM's launch announcement lists the machines it goes into. Power 9 is not one of them. The one Power 9 server IBM built for AI and high performance computing does not run IBM i at all.
- Spyre Accelerator: IBM's 7 October 2025 announcement says it became generally available on 28 October for IBM z17 and LinuxONE 5, and in early December for Power 11 servers. No Power 9 and no earlier Power generation appears in it.
- Power 9 AC922: this was the Power 9 machine with NVIDIA GPUs attached. IBM's own firmware readme for machine types 8335-GTH and 8335-GTX covers Linux only. IBM i and AIX are not in it.
Which IBM i release can a Power 9 run?
IBM i 7.5 is the top. The two rows below are IBM's wording from its upgrade planning pages, not a vendor summary.
What IBM says about Power 9 and each release
| IBM i release | What IBM says |
|---|---|
| IBM i 7.5 | IBM i 7.5 is supported on selected IBM Power servers with IBM Power11, IBM Power10, and IBM Power9 technology-based processors. |
| IBM i 7.6 | IBM i 7.6 is not supported on any servers with IBM Power9 and earlier processor technology. |
Both rows are quoted from IBM's Planning to upgrade to IBM i pages on ibm.com/support, read on 16 October 2026. The same 7.6 page says that release runs on Power 11 processors, or on Power 10 processors at minimum firmware level FW1060.
So a Power 9 shop is on a release IBM still documents, which is a better place than a Power 8 shop. The limit is the next step up. Anything IBM delivers in 7.6 or later needs a newer machine first, and that includes the pieces of the platform that newer AI tooling is built to use.
IBM's IBM i 7.3 Technology Refresh 4 page names the Power 9 models that carry IBM i: the S914 as machine type 9009-41A, the S922 as 9009-22A, the S924 as 9009-42A, the H922 as 9009-22H and the H924 as 9223-42H. IBM lists the S922 and H922 as IBM i configurations only with VIOS.
What should a Power 9 shop do first?
Three checks before you plan any AI work
- Write down the machine type and the releaseThe label on the front is not enough. You want the four character machine type and model, such as 9009-42A, and the exact IBM i release and Technology Refresh level. Every answer below depends on those two numbers.
- Check your support date, because one has already passedIBM's standard support for the S914 and the S924 ended on 31 January 2026. The E980 runs to 31 December 2027. If your machine is in the first group, you are already past the date IBM publishes, so confirm your own coverage with IBM or your business partner.
- Split the AI plan into off the box and on the boxWork that calls a model running elsewhere can start now on a supported release. Work that needs fast inferencing on your own cores needs Power 10 or Power 11, because that is where the matrix math unit lives. Price the hardware before you price the tool.
The support dates in step two are from IBM's withdrawal notification pages for 9009-41A, 9009-42A and 9080-M9S, read on 16 October 2026.

IBM Power 10
IBM's Power processor generation that preceded Power11, announced August 17, 2020 and shipping from September 2021, the first Power chip to embed Matrix Math Acceleration into every core for on-chip AI inferencing without a separate GPU. IBM began winding down new Power10 sales in February 2026.
IBM Power 11
IBM's current generation of Power processor and server hardware, announced July 8, 2025 and generally available July 25, 2025, carrying forward Power10's on-chip Matrix Math Acceleration and becoming the first Power generation to support the IBM Spyre Accelerator card.
Matrix Math Acceleration (MMA)
An on-chip acceleration feature in IBM Power10 and Power11 processors that speeds up the matrix math operations used in AI inferencing, without requiring a separate GPU.
IBM Spyre Accelerator
A PCIe4 AI inferencing card IBM ships for IBM Z, LinuxONE and Power11 systems to offload generative and agentic AI workloads from the main processor. On Power11 it is driven from a Red Hat Enterprise Linux or Red Hat OpenShift AI partition, and as of September 2026 IBM has not documented a way to use it from an IBM i partition.
IBM i
IBM's operating system for Power servers running traditional AS/400-lineage business applications, with Db2 for i built directly into the OS.
IBM i Technology Refresh (TR)
An IBM i Technology Refresh, or TR, is how IBM adds new function to an IBM i release a shop is already running: it arrives as one Technology Refresh PTF Group, and installing it leaves the release level and the machine code level unchanged. TRs are also where the platform's AI groundwork shows up, because IBM's own IBM i 7.6 TR2 notes from July 2026 document the Code for IBM i editor extensions and the IBM Bob Premium Package for i, and list 17 new IBM i Services an agent can read over SQL.
IBM System i
System i is the name IBM used for the AS/400 line from 2006 until April 2008, when the brand became IBM Power Systems and i5/OS became IBM i. For AI work the hardware is the catch, because System i machines use Power 5, Power 5+ or Power 6 processors and IBM states that IBM i 7.3 will not support Power 6 systems, so no System i can run a release IBM's current IBM i documentation covers.
IBM AIX
AIX is IBM's UNIX operating system for IBM Power hardware, the sibling of IBM i on the same servers and the source of the AIX runtime that IBM i ships as PASE for i. On Power 11 it needs AIX 7300-03-01 or higher to run in Power11 compatibility mode, and its AI packages arrive as RPMs from the AIX Toolbox for Open Source Software.
