AMD has launched its fourth generation embedded x86 processor with up to 64 Zen 4c cores
The AMD EPYC Embedded 8004 Series processor is designed for compute-intensive embedded systems with a focus on power efficiency, ranging from 12 to 64 of the new Zen 4c cores with 30% higher performance per watt than the previous chips on the same 5nm process.
The Embedded 8004 also integrates embedded features for industrial edge applications as well as networking systems, routers, security appliances, enterprise and cloud warm/cold storage.
Available in configurations ranging from 12 to 64 cores (24 to 128 threads) running at up to 2.5GHz and supporting up to 1.152TB DDR5 memory capacity (2 DIMMs/channel with 96GB DIMM size), the processors have a Thermal Design Power (TDP) profiles ranging from 70W to 225W.
The processors have 96 lanes of PCI Express Gen 5 and six channels of DDR5-4800 to connect SSDs, networking cards, and more components to create flexible and scalable system configurations.
The compact SP6 socket form factor is 19% smaller than AMD EPYC Embedded 9004 Series processors but have the same long lifecycles support of seven years to help system designers maintain platform longevity.
The SP5 package measures 72 mm x 75.4 mm and the SP6 package measures 58.5 mm x 75.4 mm
A fourth generation Direct Memory Access ( DMA) offloads data transfers from the CPU, allowing cores to focus on critical application tasks while Non-Transparent Bridging (NTB) enables data exchange between two CPUs in active-active configurations via PCIe, enabling continued operation in case of a failure.
A DRAM Flush to NVMe feature helps ensure critical data is preserved by flushing it from DRAM to nonvolatile memory in the event of a power loss while dual SPI support linkes to two SPI ROMs, one for the BIOS image and another for a secure bootloader, providing an added layer of security and Device Identity Attestation helps protect against unauthorized CPU upgrades by allowing cryptographic authentication of the processors.
