Keen-eyed hardware tipster momomo_us this week spotted that an upcoming AMD data center "Siena Dense" CPU has received verification, in the general sense, for SATA and PCI support - courtesy of the Serial ATA International Organization (SATA-IO). The information dump was uploaded to SATA-IO's online database on April 6 of this year - under the heading: "AMD EPYC 8004 Series Processors." As covered by TPU mid-way through this month the family of enterprise-grade processors, bearing codename Siena, is expected to be an entry-level alternative to the EPYC Genoa-X range, set for launch later in 2023.

The EPYC Siena series is reported to arrive with a new socket type - SP6 (LGA 4844) - which is said to be similar in size to the older Socket SP3. The upcoming large "Genoa-X" and "Bergamo" processors will sit in the already existing Socket SP5 (LGA 6096) - 2022's EPYC Genoa lineup makes use of it already. AMD has not made its SP6 socket official to the public, but industry figures have been informed that it can run up to 64 "Zen 4" cores. This new standard has been designed with more power efficient tasks in mind - targeting intelligent edge and telecommunication sectors. The smaller SP6 socket will play host to CPUs optimized for as low as 70 W operation, with hungrier variants accommodated up to 225 W. This single platform solution is said to offer 6-channel memory, 96 PCIe Gen 5.0 lanes, 48 lanes for CXL V1.1+, and 8 PCIe Gen 3.0 lanes.
