The IBM Power9 Advanced I/O family added three primary benefits. The very first, IBM Power9 AIO adds the “next-generation NVIDIA NVLink.” Read about NVLink and NVSwitch from your deep-dive look this past year. Second, it introduces OpenCAPI 4. up from three. in earlier versions of Power 9. Third, it adds support for that Open Memory Interface (OMI.) This is actually the summary of the nick:
IBM Power9 Talk At Hot Chips 31 Power9 AIO Overview
As you can easily see, by utilizing OMI, IBM has the capacity to dramatically boost the memory capacity and bandwidth over previous generation parts. IBM states the design target is 5-10ns of more latency while greatly growing bandwidth. IBM also required a jab at AMD saying how with OMI, one doesn’t need to re-spin an I/O Die to aid DDR5. This really is really a telling comment. Using the AMD EPYC 7002 series, AMD presently has more PCIe bandwidth than IBM. This past year, IBM was taking jabs at Apple because the big x86 competitor.
IBM Power9 Talk At Hot Chips 31 Minimize Quantity Of PHYs PCIe And 25G Signaling
This really is 2-socket, however it can scale as much as 16 sockets. We’d more about how these may scale to more accelerators in last year’s Hot Chips IBM coverage. Overall, the organization is searching to simplify PHYs onboard which enables it to improve bandwidth and that iOrTo devices.
OpenCAPI and NVLink Design Goals
With OpenCAPI, the organization really wants to bring coherent caching accelerators. As computing will get more heterogeneous, a lot of companies are targeting accelerators. IBM stated it believes OpenCAPI is preferable to CXL since it are designed for accelerators and memory, and it is shipping today.
IBM didn’t out a brand new NVIDIA Tesla design, however it did state that there’s a brand new NVLink coming for any new generation of GPUs, which we’d expect.

IBM sees the Power9 AIO like a key technology to allow an assorted accelerator ecosystem today with increased memory capacity and bandwidth.
Open Memory Interface
We covered this within our recent Microchip OMI piece. The fundamental idea is the fact that serial attached memory is really a lightweight, high-bandwidth interface. The OMI spec enables not only DDR4 DIMMs, but additionally future DDR5, persistent memory, tiered memory, as well as GDDR6 memory to the serial interface. Additionally, it enables someone to use greater capacities of memory. Here’s a good example of the IBM Power memory evolution.

As you can easily see, IBM gets its serial attached memory inside a smaller sized form factor.
Searching Ahead to Power10
Searching ahead, IBM is presenting OMI within this generation so the next-generation supports the feature.
IBM Power9 Talk At Hot Chips 31 Stay Tuned In For Power10
We predict Power10 to possess not only OMI, but additionally PCIe Gen5 and faster cores plus a couple of other additional features.
