Last year IBM presented details about its new Power10 family of processors: eight threads per core, 15 cores per chip, and two chips per socket, with a new core microarchitecture, all built on Samsung’s 7nm process with EUV. New technologies such as PCIe 5.0 for add-in cards, PowerAXON for chip-to-chip interconnect, and OpenCAPI for super-wide memory support made Power10 sound like a beast, but the question was always about time to market – when could customers get one? Today IBM’s Power10 E1080 Servers are being announced, aimed squarely at the cloud market.

Power10: A Brief Summary

IBM’s Power series of processors have been a steadfast progression over the last couple of decades, often using some secret manufacturing process to eke out that specialist frequency right on the bleeding edge. The new Power10 processor is also built for performance, with the 602mm2 16 core silicon die running at over 4 GHz with 8 threads per core. For yield reasons one core per chip is disabled, but a full 16 socket system can run to 1920 logical threads.

IBM built Power10 to be either in a single chip module (SCM) with one piece of silicon, or a dual-chip module (DCM) with two pieces of silicon. Where the chip really shines is in the two multi-protocol connectivity interfaces around the edges of the silicon.

PowerAXON at the corners and OMI (OpenCAPI Memory Interface) sound like amazing flexible interfaces. Running at 1 TB/sec each, the PowerAXON can be used for chip-to-chip communication, storage, regular DRAM, ASICs/FPGA connections, and clustered memory. The OMI can be used for storage also, or main DRAM, or for high-bandwidth GDDR/HBM. Together, these technologies allow for up to 8 TB per system, or 2048 TB of addressable memory across a networked cluster of systems. There’s also PCIe 5.0 x32 for add-in cards.

IBM compares Power10 against Power9: +20% single thread improvement, +30% per core improvement, and an overall 3x performance per watt against the previous 14nm processor. Also bundled is a new AI compute layer supporting four 512-bit matrix engines and eight 128-bit SIMD engines per core, providing 20x or more INT8 performance per socket.

IBM Power10 E1080

The stated E1080 design is an eight-socket system, supporting transparent memory encryption, 2.5x faster encryption, and new RAS features for advanced recovery, self-healing, and diagnostics. IBM’s materials focus on one particular benchmark: how it beats other options in a two-tier SAP Hana SD standard benchmark with only half the sockets, or an Oracle benchmark requiring only 20% of the power and number of Oracle licenses to achieve the same result.

Multiple times in the release IBM mentions ‘instant scaling, pay per use consumption’, especially as it pertains to Red Hat’s OpenShift technology in the cloud. This all pertains to IBM’s ‘Hybrid Cloud’ strategy, which is meant to mean that a business runs some private internal cloud resources while also using some cloud server provider ‘public’ resources, and it’s the public element that relates down to the cost. IBM runs its own cloud service, to which Power10 will be a part.

IBM was relatively light on details about exact SKUs to be offered, memory options, whether these will be available for direct purchase and deployment. A lot of discussions went into the new AI accelerators with ONNX frameworks as well as the operating system support for enterprise features such as side-channel attacks, intrusion detection, compliance reporting, and full-stack encryption with support for ‘quantum-safe cryptography’.

IBM is taking orders now with shipments expected to begin before the end of the month.

    I'd say not much, unless someone sponsors licensing and set up costs.
    These things are SAP HANA / Oracle monsters.
    I'd assume that these are the workloads that should be tested upon.

    "Is there any chance that Anandtech might get one in for testing?"

    they won't even buy a $100 motherboard, and you wonder why they don't get a data center quality machine that goes for, at least, $1,000,000?

    No but I bet if they really wanted they could borrow some time as a sponsored event. I suspect one of the smaller cloud providers would be more than happy to do it.

    Yeah!! Thank you so much for sharing this content. I've been looking for weeks
