Spot The Denverton: Atom C3000 Silicon On Display

There are a few news items from Computex we didn’t cover at the time that I want to visit. The first is Denverton, and how one manufacturer had a relevant beta motherboard on display during the show. Denverton is the successor to Avoton, Intel’s 8-core Atom processor that we’ve seen in the ASRock C2750D4I and other and variety of NAS and server based ‘card’ solutions (GIGABYTE showed a 46x C2750 server in 2U back at Computex in 2015). Avoton uses eight Bay Trail based cores, while Denverton will use the upgraded Cherry Trail microarchitecture design.

The Denverton based motherboard on show was an ‘early’ sample, offering four DDR4 slots supporting RDIMMs, four SATA breakout ports (for 16 SATA drives, sharing some SoC PCIe lanes), dual 10G SFP+ ports, dual gigabit network ports (via Intel I210), 32GB of eMMC and an Aspeed AST2400 board management controller. A single PCIe 3.0 x8 slot is provided for additional ality.

The chip at the center of this, after we asked nicely for the heatsink to be removed, is a 1.8 GHz Denverton part built on Intel’s 14nm process using the Airmont microarchitecture. The QKP2 code is not yet public it seems, however we were told to expect this board in a 4-to-16 core design within similar power envelopes as the previous generation. Denverton is the 14nm die shrink of Avoton, so single core performance is expected to be within a few percent but the main advantages of the die shrink will be power consumption per core.

Microarchitecture	Node	Release	Main SoC Name	Server Codename
Goldmont	14nm	2016	Apollo Lake	?
Airmont	14nm	2014	Cherry Trail	Denverton
Silvermont	22nm	2013	Bay Trail	Avoton
Saltwell	32nm	2011	Clover Trail Cedar Trail	Centerton Briarwood

IDF is currently set for mid-August, and we will have at least a trio of editors there for the ride. At this point in development, we are likely to see some announcements being made towards the Denverton platform. If there is a full release at that time, we should see full specification sheets and pricing. Failing IDF, Supercomputing16 is in November.
