Intel printed documentation indicating a significant CPU flaw much like the 2016 Silvermont C2000 bug, although retracted it claiming the problems have been mounted in firmware replace for already-deployed CPUs.

Spectre and Meltdown defined: New variants and extra environment friendly patches
Find out about these uniquely harmful vulnerabilities as TechRepublic’s James Sanders discusses up-to-date data on the newest variants and greatest mitigation methods to attenuate efficiency influence.

Sudden penalties of shrinking the lithography in CPU designs have cropped up over the previous decade, with the 32nm 2011 Sandy Bridge (Cougar Level) designs topic to I/O efficiency degradation over time, an issue that value Intel $1 billion in manufacturing stoppages and guarantee replacements. Points within the LPC clock with the 22nm Silvermont design resulted in methods “[experiencing] lack of ability besides or could stop operation,” have been disclosed in late 2016—three years after the affected CPUs shipped—leading to product failures in embedded methods.

The Silvermont bug—in any other case known as the Atom C2000 bug—resurfaced on Monday as Tom’s reported on an Intel Product Change Notification (PCN) indicating that Intel was refreshing the Apollo Lake Celeron N3350, J3355, J3455, and Pentium N4200 processors attributable to points much like these in Silvermont. This resulted in concern from homeowners of Synology NAS units, as present Synology methods make the most of Apollo Lake processors, and the corporate was among the many hardest hit with the Silvermont bug, prompting a 1-year guarantee extension for affected items.

The problem, as described in Intel’s now-retracted PCN:

On the Processor: Intel will begin transitioning from B-1 stepping of the Intel Celeron N3350, J3355, J3455 Processor and Intel Pentium N4200 Processor to F-1 stepping. The brand new F-1 stepping SKUs can be changing the B-1 stepping Celeron N3350, J3355, J3455 processors and Pentium N4200 processor on the Web of Issues (IOTG) roadmap for IOTG clients.

Clients could start transitioning all manufacturing off of the B-1 stepping and on to F-1 stepping as early as September 03, 2019 and should absolutely transition to F-1 no later than February 28, 2020. The F-1 stepping Celeron N3350E, J3355E, J3455E processors and Pentium N4200E processor have been developed for lengthy life manufacturability to fulfill the IOTG 15-year availability of Apollo Lake processors. The F-1 stepping Celeron N3350E, J3355E, J3455E processors and Pentium N4200E processor is validated for PC Consumer Use situation solely.

Intel recognized a problem with the Low Pin Rely (LPC), Actual Time Clock (RTC), SD Card interfaces on Intel Celeron N3350, J3355, J3455 processors and Intel Pentium N4200 processor leading to degradation of those indicators at a fee greater than Intel’s high quality objectives after a number of years in service.

The unique PCN “had inaccurate data,” in accordance with an Intel spokesperson, who famous revised model has now been printed. Additional, Intel offered a touch upon the discrepancy:

There are not any modifications to the B-1 Stepping of the Intel Celeron N3350, J3355, J3455 Processors and Intel Pentium N4200 Processor as they meet all Intel high quality objectives for PC Utilization and can proceed to be out there. The F-1 Apollo Lake Intel Celeron N3350, J3355, J3455 Processors and Intel Pentium N4200 Processor meet all Intel high quality objectives for PC Utilization. 

With IOTG’s operational resolution to converge onto a single package deal for the entire IOTG Apollo Lake Processors, the F-1 stepping Celeron N3350, J3355, J3455 Processors and Pentium N4200 Processor has a slight enhance in Z top in comparison with the B-1 Stepping.

Actually, Pentium and Celeron units are not often used for enterprise deployment of major workstations. Pentium N4200-powered netbooks are broadly produced by HP and Lenovo for the patron market, although the affected Celeron and Pentium processors are widespread in enterprise for Web of Issues (IoT) units, together with NAS units from Synology and QNAP which can be common amongst SMBs and prosumers. IoT units that ship with these processors are usually utilized in always-on situations, which fairly rightly prompts issues when LPC flaws are found.

TechRepublic is looking for clarification on Intel’s definition of “PC Consumer Use” validation and the way this definition impacts always-on situations for IoT, and can replace this story if/when Intel offers a response.

Replace: In an announcement, Synology “confirmed with the chipset vendor [Intel] that the entire associated product designs conform to the seller’s newest design tips (July, 2019). In the meantime, Synology has not noticed any irregular error charges for the reason that preliminary launch of the associated merchandise.”

Replace 2: Intel offered this assertion to TechRepublic:

Intel initially printed a specification replace in July 2017 outlining mitigations for Errata APL47 to keep away from sign degradations beneath sure situations within the outer years of use. When the B-1 Stepping is utilized in accordance to the printed specs and design tips, it meets PC Consumer Utilization necessities. With the F-1 Stepping, the mitigations talked about in Errata APL47 are not required to fulfill PC Consumer Utilization necessities.

Additional, Intel famous that the errata data signifies the problem was mounted in firmware. It is unclear what efficiency influence this replace would have on the affected low-power processors.
