AMD Launches the EPYC Embedded 9005 "Turin" Family of Server Processors
AMD today launched the EPYC Embedded 9005 line of server processors in the embedded form-factor. These are non-socketed variants of the EPYC 9005 "Turin" server processors. The chips are intended for servers and other enterprise applications where processor replacements or upgradability are not a consideration. The EPYC Embedded 9005 "Turin" are otherwise every bit similar to the regular socketed EPYC 9005 series. These chips are based on a BGA version of the "Turin" chiplet-based processor, and powered by the "Zen 5" microarchitecture. Besides the BGA package, the EPYC Embedded 9005 series comes with a few features relevant to its form-factor and target use-cases.
To begin with, the EPYC Embedded 9005 "Turin" series comes with NTB (non-transparent bridging), a technology that enables high-performance data transfer between two processor packages across different memory domains. NTB doesn't use Infinity Fabric or even CXL, but a regular PCI-Express 5.0 x16 connection. It isn't intended to provide cache coherence, but to absorb faults across various memory domains. Next up, the series supports DRAM flush for enhanced power-loss mitigation. Upon detecting a power loss, the processor immediately dumps memory onto NVMe storage, before the machine turns off. On restart, the BIOS copies this memory dump from the NVMe SSD back to DRAM. Thirdly, the processors in the series support dual SPI flash interfaces, which enables system architects to embed lightweight operating systems directly onto a 64 MB SPI flash ROM, besides the primary SPI flash that stores the system BIOS. This lightweight OS can act like a bootloader for operating systems in other local storage devices. Read full story
