# Intel Atom P5942B Server CPU: Intel Also called intel atom p5942b, atom p5942b, p5942b, atom-p5942b Intel, Server CPU, Snow Ridge Intel Atom P server processor on Snow Ridge, with 16 cores and 16 threads and 18 MB L3 on a 10 nm process addressing up to 128 GB. ## What you need to know Intel Atom P5942B is a aging server cpu. Intel Atom P5942B launched in January 1, 2020., It has 16 cores and 16 threads on Snow Ridge. Treat the spec table as the facts. Age alone does not tell you to throw it out. - **Still good?**: Yes, for lighter work **Product age**: 6 years old **Upgrade pressure**: Moderate Feex says Server parts care about cores, memory channels, and the platform. Gaming charts are the wrong ruler. ## What this hardware means today Age and usefulness are not the same number. This page keeps them separate. - **Performance today**: **Good.** Good for the class when RAM, storage, and the GPU keep up. **Product age 6 years old**: **Aging.** Launched January 1, 2020. Newer platforms exist. That does not make this chip unusable by itself. **Support status **: **Supported.** Current Windows and current applications still run on this class of CPU. Platform BIOS support depends on the motherboard or laptop vendor. **Upgrade pressure **: **Moderate.** Upgrade pressure comes from platform features and specific CPU-bound work, not from the chip being unusable. ## Where does it sit? Snow Ridge sits on Intel's recent Core timeline. Later desktop branding moved toward Core Ultra. 11th Gen 12th Gen 13th Gen 14th Gen Core Ultra ## Performance context These are qualitative readings, not a fake 8.7 out of 10. Workload still wins. ### Gaming: Poor fit Not the job. Use a desktop or workstation part if games are the point. ### Productivity: Good 16 cores cover office, browser, and compile work in this class. ### Multithreaded workloads: Good 16 threads. Heavy encodes still scale further on higher-core parts. ### General use: Excellent Everyday Windows use is not where most people notice this SKU first. ### Efficiency: Good Power is not recorded on this sheet. ## Should you upgrade? Probably not based on CPU performance alone. ### Upgrade makes more sense if - Your workload is strongly CPU limited - You need a platform this SKU cannot offer - You need substantially more multicore performance - You need newer connectivity that your current board cannot offer ### Upgrade makes less sense if - The GPU is the real bottleneck - Current applications are already responsive - The CPU rarely limits your workload ## Specifications Figures below follow the Feex Hardware Database record for this SKU. Fields without a recorded value are omitted. ### Processor Intel Atom P5942B is built on Snow Ridge using a 10 nm process. | Manufacturer | Intel | | --------------------- | ----------------------------- | | Family | Atom P | | Architecture | Snow Ridge | | Generation | Intel Atom Processor P Series | | Manufacturing process | 10 nm | | Segment | Server | ### Cores and threads Intel Atom P5942B has 16 cores and 16 threads. | Cores | 16 | | ------- | -- | | Threads | 16 | ### Clock speeds Base clock is 2.2 GHz. | Base frequency | 2.2 GHz | | -------------- | ------- | ### Cache Cache on this sheet is 18 MB L3. | L3 cache | 18 MB | | ----------- | ----- | | Total cache | 18 MB | ### Memory Intel Atom P5942B addresses 128 GB across 2 memory channels. | Supported types | DDR4 | | --------------- | ------ | | Max capacity | 128 GB | | Channels | 2 | ### Package and power | PCIe | Revision 3.0, 32 lanes | | ---- | ---------------------- | ### Market Intel Atom P5942B launched January 1, 2020. | Launch date | January 1, 2020 | | ----------- | --------------- | | Model | P5942B | ### Features Intel Atom P5942B records 2 instruction sets on this sheet. | Instruction sets | 64-bit (x86-64)SSE4.2 | | ---------------- | ---------------------------------------------------------------------------- | | Security | Boot GuardHardware RNG | | Virtualization | Extended Page Tables (EPT)VT-d (DMA Remapping)VT-x (Hardware Virtualization) | ## Compatibility | Memory | DDR4, up to 128 GB | | ------ | ------------------ | Confirm the platform from the manufacturer sheet before you buy a board for this SKU. Cooler clearance, VRM quality, and power limits matter as much as the socket name. Read the memory list on the board. The CPU can list more standards than one motherboard will accept. ### No post after a CPU swap Clear CMOS only after you confirm the board list includes this SKU and the BIOS is new enough. A supported name on a box is not the same as a flashed board. ## Related These entities connect to this article. Type is shown on every link.
