Intel® Atom™ C3950

The Intel Atom C3950 is a server processor with 16 cores and 16 threads, built on the Denverton architecture. It launched in Jul 2017. Clocks run from 1.7 GHz base to 2.2 GHz boost. A 16-MB L3 cache backs the cores (1.0 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 (16 lanes). Rated TDP is 24 W. Notable platform capabilities: Extended Page Tables (EPT).

The Intel Atom C3950 has 16 physical cores and runs 16 logical threads. It does not support simultaneous multithreading, so its thread count equals its core count. It runs at a base clock of 1.70 GHz and boosts up to 2.20 GHz.

The Intel Atom C3950 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 Jul 2017.

The Intel Atom C3950 has 16 MB of L3 cache. That adds up to about 16.0 MB of cache, or 1.00 MB per core. Feex has no recorded L1 cache size for this processor.

The Intel Atom C3950 supports DDR4 memory, addresses up to 256 GB of memory, uses 2 memory channels and runs memory at up to 2,400 MT/s. It does not support DDR5 and LPDDR memory.

The Intel Atom C3950 uses the FCBGA1310 socket, supports PCI Express 3.0 and provides up to 16 PCIe lanes.

The Intel Atom C3950 has a rated TDP of 24 W.
