AMD has announced the EPYC 8004-series Siena processors. The new processors have an all-new SP6 form factor, up to 64 Zen 4c cores, and a six-channel DDR5 memory subsystem. AMD’s EPYC ‘Siena’ CPUs are intended for edge and communications servers that require improved I/O and power efficiency over raw speed.
AMD’s EPYC 8004-series ‘Siena’ processors for intelligent edge applications use an all-new SP6 architecture but re-use essential components of Bergamo CPUs for high-density servers, such as four 16-core Zen 4c general-purpose chiplets and I/O die. The processor has eight to 64 cores running at 2.0 – 3.10 GHz with a TDP of 80W to 200W. Meanwhile, these CPUs can be configured for up to 225W TDP or reduced to 70W power consumption.
While AMD’s Zen 4c cores are smaller and less power hungry than full-fledged Zen 4 cores, they offer the same feature set and can thus run applications that rely on instructions like AVX-512. Although AMD’s EPYC 9004-series processors provide superior performance, AMD’s EPYC 8004-series CPUs offer lower total cost of ownership and improved power efficiency. In SPECpower_ssj 2008, AMD says that Siena provides up to 2x greater performance per watt than competitors (Xeon Platinum 8490H, Xeon Platinum 8471N).
According to AMD benchmark findings, the EPYC 8324P has up to 1.16x greater performance per core in video encoding applications (than Intel’s 32-core Xeon 6421N). In IoT Edge gateway applications, an eight-core EPYC 8024P outperforms an eight-core competition (Intel’s Xeon Platinum 8471N) by roughly 1.8x the total SPECrate 2017_int_base throughput performance per 8kW rack.
The new AMD EPYC 8004-series processors include a six-channel DDR5-4800 subsystem with memory capability for up to 1.152 TB. Intelligent edge servers are a newer application type. Some of these devices have regular CPUs, while others have special-purpose accelerators. However, modern I/O capabilities are required for such machines. As a result, AMD’s Siena has 96 PCIe 5.0 lanes, 48 of which support the CXL 1.1+ protocol for powerful contemporary accelerators (for AI inference or other applications) and/or memory expanders.
AMD said its EPYC 8004 ‘Siena’ CPUs are now available in new Dell (PowerEdge C6615), Lenovo (ThinkEdge SE455 V3), and Supermicro (H13 family of WIO Servers) edge servers. Ericsson and Microsoft Azure have also praised the new CPUs.
AMD’s EPYC 8004-series ‘Siena’ processors complete AMD’s 4th Generation EPYC range, which includes general-purpose servers (Genoa), high-performance computing (Genoa-X), cloud native (Bergamo), and intelligent edge (Siena) machines.
