Intel® Atom™ P6952-3

The Intel Atom P6952-3 is a server processor with 20 cores and 20 threads, built on the Grand Ridge architecture. It launched in Jan 2026. A 20-MB L3 cache backs the cores (2.0 MB per core). It addresses DDR5 memory up to 128 GB across 2 channels. It uses the FCBGA2147 socket. Rated TDP is 74 W. Notable platform capabilities: VT-x (Hardware Virtualization).

The Intel Atom P6952-3 has 20 physical cores and runs 20 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 P6952-3 is a server processor, belongs to the Intel Atom P family, uses the Grand Ridge architecture and carries the codename Grand Ridge. It launched in Jan 2026.

The Intel Atom P6952-3 has 20 MB of L2 cache and 20 MB of L3 cache. That adds up to about 40.0 MB of cache, or 2.00 MB per core. Feex has no recorded L1 cache size for this processor.

The Intel Atom P6952-3 has a 2-level cache hierarchy: L2 at 20 MB and L3 at 20 MB. L2 is the largest level and makes up about 50% of the cache listed here.

The Intel Atom P6952-3 supports DDR5 memory, addresses up to 128 GB of memory and uses 2 memory channels. It does not support DDR4 and LPDDR memory.
