Overview
SummaryThe Intel Atom C3338R is a server processor with 2 cores and 2 threads, built on the Denverton architecture. It launched in Apr 2020. Clocks run from 1.8 GHz base to 2.2 GHz boost. A 4-MB L3 cache backs the cores (2.0 MB per core). It addresses DDR4 memory up to 128 GB across 1 channels. The chip drops into the FCBGA1310 socket and exposes PCIe 3.0 (10 lanes). Rated TDP is 11 W. Notable platform capabilities: Extended Page Tables (EPT).
Core Configuration
5 specsThe Intel Atom C3338R has 2 physical cores and runs 2 logical threads. It does not support simultaneous multithreading, so its thread count equals its core count. It runs at a base clock of 1.80 GHz and boosts up to 2.20 GHz.
