Intel Unveils Atom x6000E Series, Celeron and Pentium Elkhart Lake IoT Edge Processors

We’ve been expecting Intel Elkhart Lake processors for more than a year, and the company has now officially announced the “IoT-enhanced processors” with a new Atom x6000E Series, as well as some Celeron and Pentium N/J parts. Last year, we thought Elkhart Lake would succeed Gemini lake, but the new 11th generation 10nm processors may not be found in many consumer devices, as they target IoT edge applications with additional artificial intelligence (AI), security, functional safety, and real-time capabilities. The company has announced a total of 12 Elkhart Lake processors with all but one featuring 10th Generation Intel UHD Graphics and divided into eight Atom x6000E series processors. and four Celeron/Pentium parts Intel further explains Elkhart Lake IoT edge processors deliver up to two times better 3D graphics compared to Pentium J4205 Apollo Lake processor, come with Intel Programmable Services Engine real-time offload engine with support for out-of-band and in-band […]

Updated x86/x64 Software Optimization Manual Reveals More Intel Tremont Details

Tremont Microarchitecture Processor Pipeline

We first found out about Tremont microarchitecture in April 2018 in some Intel documents and Linux mainline source showing it was likely meant to be Goldmont Plus successor. Last year, Intel formally announced Tremont architecture providing some of the details with a block diagram and key features. But this morning, we were informed by email of a new revision of the x86/x64 Software Optimization Manual (PDF) with even further details about Tremont architecture. If you want to know all the details, jump to 4.1 Tremont Architecture section of the document, but here are some of the highlights / improvements over Golmond Plus microarchitecture: Enhanced branch prediction unit. Increased capacity with improved path-based conditional and indirect prediction. New committed Return Stack Buffer. Clustered 6-wide out-of-order front-end fetch and decode pipeline. Banked ICache with dual 16B reads. Two 3-wide decode clusters enabling up to 6 instructions per cycle. Deeper back-end out-of-order windows. […]

Intel Elkhart Lake Processors To Succeed Gemini Lake Processors in 2020

Intel Gemini Lake processors were highly anticipated as soon as they were first reported in September 2016, and even more so before launch since Gemini Lake products promised to be about as expensive as their older Apollo Lake counterparts. Interest somewhat fizzled despite a clear performance advantage over the previous generation, as prices did not match initial expectations, likely due to a shortage of Intel cheaper processors. In recent weeks, we started to read about Intel Elkhart Lake processors that are meant to be the successors of Gemini Lake processors, based on Tremont microarchitecture, and featuring Intel “i915” Gen11 graphics. The new processor should be manufactured using a 10nm process, but it’s still unclear whether some Elkhart Lake processors will be part of Intel Foveros which combines a fast Sunny Cove core with several Atom class Tremont cores. That’s about all we know from the technical side so far. A […]
