Intel® Atom™ P5942B

The Intel Atom P5942B is a server processor with 16 cores and 16 threads, built on the Snow Ridge architecture. It launched in Jan 2020. A 18-MB L3 cache backs the cores (1.1 MB per core). It addresses DDR4 memory up to 128 GB across 2 channels. Notable platform capabilities: Extended Page Tables (EPT).

The Intel Atom P5942B 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 2.20 GHz.

The Intel Atom P5942B is a server processor, belongs to the Intel Atom P family, uses the Snow Ridge architecture, carries the codename Snow Ridge and is manufactured on a 10 nm process. It launched in Jan 2020.

The Intel Atom P5942B has 18 MB of L3 cache. That adds up to about 18.0 MB of cache, or 1.13 MB per core. Feex has no recorded L1 cache size for this processor.

The Intel Atom P5942B supports DDR4 memory, addresses up to 128 GB of memory, uses 2 memory channels, runs memory at up to 2,933 MT/s and delivers up to 46.9 GB/s of memory bandwidth. It does not support DDR5 and LPDDR memory.

The Intel Atom P5942B supports PCI Express 3.0 and provides up to 32 PCIe lanes.

Instruction sets, security, virtualization, AI acceleration and OS readiness. Features are listed as supported, explicitly not supported, or not recorded; a feature that is not recorded is not the same as unsupported.

The Intel Atom P5942B is also identified by the model number P5942B.
