AMD has been showing off a reference Seattle-based server at Hot Chips and The Tech Report had an opportunity to see it.  Eight 64-bit Cortex-A57 chips are set up in pairs, each pair sharing 1MB of L2 cache while the 8MB of L3 cache is accessible by all eight chips as well as the coprocessors, memory controller, and I/O subsystems.  The system can address up to 128GB of DDR3 or DDR4, and you get support fot 8 SATA 6Gbps ports and 8 lanes of PCIe 3.0 to apportion between the slots.  There is a secure System Control Processor, a partitioned Cortex-A5 core with its own ROM, RAM, and I/O to control power, boot and configuration control with support for TrustZone as well as a Cryptographic Coprocessor which accelerates all encryption processes as you might well expect.  Read on for more information about AMD's unique new take on server technology.

"For some time now, the features of AMD's Seattle server processor have been painted in broad brush strokes. This morning, at the Hot Chips symposium, AMD is filling in most of the missing details. We were treated to an advance briefing last week, where AMD provided previously confidential information about Seattle's cache network, memory controller, I/O features, and coprocessors."
