At STH, we have tested several Intel Atom C3000 models including the Intel Atom C3338, Atom C3558, and Atom C3958 among others, but we had not tested the Intel Atom C3758 yet. That ends with this review. After getting some time with the 8-core Intel Atom C3758, we think it offers a strong value proposition for many embedded appliances. In fact, this low power CPU is one that we will end up recommending based on its performance.

Key stats for the Intel Atom C3758: 8 cores / 8 threads running at a 2.2GHz clock and a 16MB cache. This is one of Intel’s “Denverton” Atom C3000 SKUs with QuickAssist onboard. This is a $193 list price part features a low 25W TDP. Here is the ARK page with the feature set.

Here is what the lscpu output looks like for the chips:

Test Configuration

Here is our basic configuration for this class of CPU:

Motherboard: Supermicro A2SDi-8C+-HLN4F

CPU: Intel Atom C3758 (embedded)

RAM: 4x 16GB DDR4-2400 ECC RDIMMs

SSD: Intel DC S3710 400GB

SATADOM: Supermicro 32GB SATADOM

The CPU itself supports up to 256GB of RAM, in a 4x 64GB configuration. For this class of SKU, that is plenty and our most common configurations are 32GB and 64GB in this range of processor.

For those who want a review of the Supermicro A2SDi-8C+-HLN4F, that is coming very soon. This small mITX platform is extremely interesting both as a network and firewall appliance as well as the base of a storage solution. For 2U 10 bay 3.5″ software raid boxes, for example, the Intel Atom C3758 has plenty of power and the Supermicro A2SDi-8C+-HLN4F has the onboard features to make a very low cost, low power, and yet high-performing system.

Since the CPUs are affixed to motherboards directly, we publish our power consumption figures at the platform-level. This is doubly important in this SoC range since other platform components can have a large impact on overall power consumption sometimes more than the primary SoC. Stay tuned for the upcoming review. It will not be long as the draft is already complete.

Next, we are going to take a look at our Intel Atom C3758 benchmarks, we are then going to focus on power consumption then conclude with our final words on the processors.
