What the Atom P5962B is
The Atom P5962B is a 24-core network processor that Intel listed in the first quarter of 2020 with the Snow Ridge P5000 range for base transceiver stations. Its Tremont cores run a fixed 2.2 GHz without boost across 24 threads with no Hyper-Threading. Cache is 27 MB of L2 with no L3, and the 10 nm process suits deterministic forwarding work.
The chip targets wireline access and edge routing that need many small cores with accelerators. Fixed clocks keep packet timing steady, since no turbo table changes lane or memory behavior. The BGA2106 package solders to the board with 2106 balls in a 47.5 by 47.5 mm flip chip, so there is no socket retention.
QuickAssist accelerates crypto and compression inline, while 16 USB and LAN plus UART cover board management. The multiplier is locked. The 85 C maximum with minus 40 C minimum suits outdoor cabinets as well as data closets.
Socket and motherboard compatibility
The P5962B fits BGA 2106 only. The chip solders to the network board, so there is no socket retention and no later processor upgrade. Board support is fixed to the BGA2106 platform with DDR4 ECC memory and a SKU matched lane layout.
Because the package is soldered, buyers compare complete appliances rather than separate parts. A buyer who needs fewer cores in the same footprint steps to the Intel Atom P5942B with 16 cores. The 24-core flagship stays in its high density role for its whole service life.
The Socket vs chipset: what decides whether a CPU works guide explains why embedded compatibility lives in board design files rather than a CPU support list. For service, a failed processor means a board replacement through the vendor.
Memory, PCIe and cooling
The memory controller supports DDR4 up to 2933 MT/s across two channels to 128 GB with ECC. Population follows the board layout with DIMM or soldered memory per appliance design. Capacity and ECC join the SKU as lasting choices, since appliance memory is fixed at build time.
The SoC provides 32 PCIe lanes as 16 Gen3 plus 16 Gen2 for NICs, NVMe and storage controllers. Boards split the lanes across multiple 25 GbE ports and NVMe, with the exact split fixed per design. Cooler mounting uses no desktop pattern. Cooling follows the appliance thermal design with a board heatsink and chassis airflow for network temperatures.
Twenty four cores without Hyper-Threading suit deterministic forwarding. Each core keeps its own L2 slice from the shared 27 MB pool, which avoids noisy neighbor effects under load. QuickAssist offload matters more than headline clocks for crypto heavy templates.
Upgrade paths
On the same BGA2106 footprint there is no CPU upgrade path, since the chip is soldered. Owners who need different density move to another BGA2106 board with a P sibling rather than a chip swap. Port count and memory size remain the practical choices.
Within Snow Ridge P, the steps down are the Intel Atom P5942B for 16 cores, the Intel Atom P5931B for 12 cores and the Intel Atom P5921B for 8 cores. All four share 2.2 GHz fixed clocks and BGA2106, so the choice is core count and L2 size rather than speed.
Moving past BGA2106 entirely means a new board on Xeon D or Xeon Scalable with more lanes and channels. For buyers choosing in 2020, the P5962B suited the densest 24-core templates, while smaller P parts asked lower power. The range shares Snow Ridge and 10 nm, but each SKU ships soldered to its own board.
Frequently asked questions
What socket does the Intel Atom P5962B use?
It uses BGA 2106, soldered with 2106 balls. The chip cannot be removed, so an upgrade means replacing the board.
What memory does the P5962B support?
DDR4 up to 2933 MT/s with ECC in two channels to 128 GB. Population follows the board layout per appliance design.
Can the P5962B boost above 2.2 GHz?
No. The chip runs a fixed 2.2 GHz without turbo or Hyper-Threading. Deterministic clocks suit forwarding templates.
How does the P5962B differ from the P5942B?
The P5962B has 24 cores with 27 MB L2, while the Intel Atom P5942B has 16 cores with 18 MB L2. Both share 2.2 GHz fixed clocks and BGA2106.
