Více hluku Denvertonu: Funkce G10AB ST GIGABYTE neohlášené 0jádrové jádro C16

Dnešní server GIGABYTE (serverové rameno společnosti GIGABYTE, který je jiným týmem BU na základním desce) zvedl víko na nové desce MA10-ST0 a kombinace SoC, zaměřené přímo na trh s chladnými sklady nebo okraji. Jedná se o podporu základny až pro jednotky 16 SATA přes SFF8087, slot PCIe x8, gigabitový ethernet 10 přes dva porty SFP + a funkce správy serveru prostřednictvím Aspeed AST2400. Pro funkce server / podnik jsou také přítomny záhlaví TPM a hlavička COM. Zajímavým krokem v tomto příběhu je však SoC v srdci jednotky.

GIGABYTE Server has announced they are using the C3958 SoC, listed as a 16-core part at 31W TDP and supporting DDR4-2400. The C3000 series is known as the Denverton family of CPUs, based on Intel’s Goldmont Atom microarchitecture. The Denverton CPU family has been formally announced, although only as a single SKU, the dual core C3338, which is present in some enterprise NAS devices. Some others have cited cloud instances featuring unannounced Denverton CPUs being deployed and available by cloud providers. This C3958 is another unannounced processor from Intel.

Intel’s Atom line in this market is still recovering from the Avoton/Rangeley issue that cropped up 18-24 months after launch, which had an outside chance of burning out the signal generator resulting in a system that would be unable to be repaired (we are told that an unusual spike in failures is not expected from this, but for users who deploy 10-15 year embedded devices it might be in the back of their minds). From this, Intel released a new stepping of the CPU to address the bug, and some have predicted that the delays to the formal announcement and release of the Denverton stack (some 12 months or more after the expected announcement date) is due to ensuring Denverton does not have this issue.

As for the C3958, GIGABYTE Server lists this as Intel’s top Denverton SoC model, running at 16 cores, 1MB of L2 per core, 2.0 GHz base frequency (no word on turbo), support for up to 128GB of DDR4-2400 RDIMMs (or 64GB of UDIMMs, i.e. 4x16GB modules) and having a 31W TDP. Typically around this SoC level, we might expect to compare it to an E3-1200 v6 series processor, although those CPUs start at 72W. The previous generation Rangeley processor topped out at 8 cores and 2.4 GHz for 20W, so on paper there looks to be some efficiency gain despite the frequency decrease.

Pokud jde o základní desku MA10-ST0, spolu se všemi výše uvedenými funkcemi přichází také s technologií 32GB blesku eMMC, který dovoluje uživateli nainstalovat operační systém založený na úložištích pro nasazení v síti bez použití libovolného portu SATA na palubě. Server GIGABYTE nám řekl, že deska je v podstatě připravena a zúčastněné strany by se měly dostat do kontaktu s místními zástupci.
