AMD unveils Zen 5c embedded processors, 9005 EPYC series optimized for edge computing
The warranty of EPYC Embedded 9005 series CPUs has also been extended from five to seven years

AMD's Zen 5 architecture has officially entered the embedded market with the introduction of the EPYC Embedded 9005 series. The new chips take advantage of AMD's compact Zen 5c architecture, which is optimized for density-focused computing and edge tasks.
AMD is offering a wide gamut of SKUs to serve as many customers as possible, similar to previous generations. Core counts range from "entry-level" models offering just 8 CPU cores, all the way to its flagship Embedded 9965, offering 192 cores. Likewise, TDP ranges significantly depending on core count — the eight-core model is paired to a 125W TDP, while the 192-core behemoth goes up to a whopping 500W TDP to keep all the cores from getting too toasty.
The new Embedded 9005 series (with AMD's Zen 5c architecture) allegedly has 30 to 60% greater data processing throughput compared to the prior generation for networking and storage-focused workloads. The company also says Zen 5c cores offer an estimated 30% greater energy efficency than Intel's 6th Gen Xeon competitors.
Memory capacity goes tops out at a stunning 6TB of DDR5 per CPU socket, and the new chips support up to 160 PCIe 5.0 lanes, with CXL 2.0 support for greater storage expansion and high-speed networking between storage applications. The new chips also retain the same SP5 socket as the previous-gen Embedded 9004 series, enabling system integrators and IT to upgrade outgoing SP5 systems with the newer Embedded 9005-series chips.
The Embedded 9005 series will live in unison with the outgoing Zen 5 and Zen 5c-based EPYC 9005 series, of which many of the flagship Zen 5c counterparts have identical specs to their Embedded counterparts. The target audience for AMD's new Embedded CPUs is edge computing platforms, which prioritize compute density over anything else. The new lineup is also designed around a longer lifecycle; AMD has boosted the CPU warranty of its Embedded 9005 series from 5 years to 7 years.
This change has been allegedly adapted for "embedded systems running mission-critical applications in harsh conditions, minimizing unplanned downtime, repairs, and costly system replacements."

Interesting, then I wait for the upgrade for all the zen5 line...usertests said:Identical to other Zen 5c Epyc, so TSMC N3E. -
Rob1C They made Zen 5 Turin with a maximum of 128 cores.Reply
They made Zen 5c with a maximum of 192 cores, by cutting the cache in half.
They should make (new) Zen 5b Turin with 256 cores; use X3D to add the cache back.
They should make (new) Zen 5a Turin without (normal) cache and 256 cores. Use X3D to add full sized cache like Zen 5.
They should make (new) Zen 5d Turin without (normal) cache and 256 cores. Use X3D to add double sized cache compared to Zen 5.
Maybe not the most cost effective but for EPYC it's a small additional cost on a per-core basis. With a budget of $25 per core x 256 that gives you an additional $6400 per CPU to play with.
A 256 core CPU with double sized cache could cost less than $20K, all socket compatible; though either lower clocks or a new motherboard rated for 600W+ CPU would certainly be necessary. Though they could plan for next time, when they are down to 1nm, and probably stuff 512 -d (cacheless (X3D) -c) cores into the die.
