Intel® Atom™ C3558R

The Intel Atom C3558R is a server processor with 4 cores and 4 threads, built on the Denverton architecture. It launched in Apr 2020. A 8-MB L3 cache backs the cores (2.0 MB per core). It addresses DDR4 memory up to 256 GB across 2 channels. The chip drops into the FCBGA1310 socket and exposes PCIe 3.0 (20 lanes). Rated TDP is 17 W. Notable platform capabilities: Extended Page Tables (EPT).

The Intel Atom C3558R has 4 physical cores and runs 4 logical threads. It does not support simultaneous multithreading, so its thread count equals its core count. It runs at a base clock of 2.40 GHz.

The Intel Atom C3558R is a server processor, belongs to the Intel Atom C family, uses the Denverton architecture, carries the codename Denverton and is manufactured on a 14 nm process. It launched in Apr 2020.

The Intel Atom C3558R has 8 MB of L3 cache. That adds up to about 8.0 MB of cache, or 2.00 MB per core. Feex has no recorded L1 cache size for this processor.

The Intel Atom C3558R supports DDR4 memory, addresses up to 256 GB of memory, uses 2 memory channels, runs memory at up to 2,400 MT/s and delivers up to 38.4 GB/s of memory bandwidth. It does not support DDR5 and LPDDR memory.

The Intel Atom C3558R uses the FCBGA1310 socket, supports PCI Express 3.0 and provides up to 20 PCIe lanes.
