CPU Generations and Embedded Processors Explained

An embedded processor is a processor built into a dedicated device, such as a machine controller, a gateway, a medical instrument or a vehicle computer, to do one job for many years, rather than sold to run whatever software a PC owner chooses. The term covers a wide range of chips, from microcontrollers that draw milliwatts to Intel Core, AMD Ryzen Embedded and NVIDIA Jetson processors that run vision and AI workloads.

Pick almost any industrial computer and the specification leads with a processor and a generation: 13th Gen Intel Core, Intel Core Ultra Series 2, AMD Ryzen Embedded V2000, NVIDIA Jetson Orin. On a consumer PC the generation is shorthand for speed. On an industrial system it tells you far more, about the platform, the memory and PCIe it supports, the power it draws and how long it will be made, and the newest part is rarely the right answer.

This guide explains the types of embedded processor, what a CPU generation actually signals, how to read Intel, AMD, Arm and Jetson names, what makes an embedded SKU different from its consumer twin, and how to choose a processor for a system that has to run unchanged for years.

Embedded processors fall into a handful of types, set by how much is on the chip and what software it runs. The boundaries blur, because most modern parts are systems on chip that mix several types on one die, but the table is a useful map.

Our explainer on what an embedded system is covers the devices these chips go into, and our guide to the system on chip explains why most modern embedded processors are SoCs. For the basics of the processor itself, see what a CPU is.

A microcontroller is one kind of embedded processor: a small CPU core with its program flash, RAM and peripherals on the same chip, running firmware or a real-time operating system directly. The word embedded processor usually means something larger, an applications processor or x86 part that uses external memory, has an MMU for memory protection and boots a full operating system such as Linux or Windows.

Many products use both. The applications processor runs the user interface, the networking and the analytics, while a microcontroller, or a Cortex-M core built into the same SoC, handles the fast control loop close to the hardware. Our guide to Arm architecture explains the Cortex-A, Cortex-R and Cortex-M profiles behind that split.

A CPU generation tells you which processor family and technology period a part belongs to. It is not a performance score: a low-power part of a new generation can be slower than a high-power part of the previous one. What it does signal is the platform around the processor.

Hybrid layouts deserve a note. Since Alder Lake, many Intel processors mix performance cores and efficient cores, which changes how software is scheduled and how real-time tasks should be pinned; our guide to P-cores and E-cores explains it. Our comparison of DDR4 and DDR5 covers the memory side, and PCIe generations covers the lanes.

Intel’s naming changed in 2023, from numbered Core generations to Core Ultra and Core series, and its embedded lines carry codenames that matter more than the marketing name when you are matching boards. The table lists the families most often found in industrial computers today, with approximate launch years.

Because the name no longer carries a simple generation digit, check the exact model on Intel’s specification pages and confirm the codename against the board. Our guide to Intel Core Ultra explains the Series 1, 2 and 3 split, and Core Ultra vs Core i7 covers the rename. Intel’s processors in our range are gathered on our Intel pages.

Older names such as Core i5-13500 put the generation in the leading digits. Newer names such as Core Ultra 7 255H or Core 3 304 use series naming, so the digits identify the model rather than the year. The letter at the end still matters, because it separates mobile, desktop and embedded parts of the same design.

Read the table as a guide rather than a rule: suffixes shift between generations, and newer embedded listings add PE, PTE or PQE variants. Intel’s specification page for the exact part confirms its power, use conditions and availability. Features such as hyper-threading also vary by generation, so check them per model rather than assuming them from the tier.

AMD’s embedded naming is less suffix-led than Intel’s. Ryzen Embedded parts are grouped by series, and each series maps to a Zen architecture: the V1000 and R1000 use Zen, the R2000 Zen+, the V2000 Zen 2 and the V3000 Zen 3. Newer embedded Ryzen 7000 and 8000 parts follow the mobile names with long-life support, and EPYC Embedded covers high-core-count edge servers. Check the exact family, core count, graphics, power and lifecycle status rather than the digits. Our Ryzen Embedded V1000 and R2000 pages list two of the series we stock, and our guide to AMD EPYC Embedded covers the server end.

Arm is the architecture and core design, not the chip maker. The finished processor is sold under the silicon vendor’s name, such as NXP i.MX, Rockchip RK or Qualcomm QCS, so two Arm parts can differ greatly in CPU cores, GPU, NPU, memory and I/O. NVIDIA Jetson modules are named by family (Orin, Thor) and class (Nano, NX, AGX), with Industrial variants for harsher deployments. The cheatsheet below is a quick key.

A consumer processor is chosen for peak performance and replaced within a year or two. An industrial system is chosen to run, unchanged, for the better part of a decade, so the priorities invert. Most processor makers keep an embedded line for that reason, and often the embedded part is the same silicon as a consumer part, sold under different terms.

Our own range shows the pair side by side: the ASRock Industrial NUC 1300/D4 series offers the same board with either the Core i3-1315U or the Core i3-1315UE, so a design can choose the embedded part without changing anything else. The same pattern runs through AMD’s Ryzen Embedded line and the industrial grades of Arm SoCs, which add wider temperature ratings.

Temperature is where industrial parts differ most. Industrial-grade Atom RE parts, Arm SoCs and Jetson Industrial modules are rated for wider temperatures than consumer chips, and boards built on them commonly reach −20 to 70 °C or −40 to 85 °C. Our explainer on the industrial temperature range sets out what those ratings mean in an enclosure.

Longer than consumer parts, and the commitment is published. Processor makers run longevity or embedded roadmap programmes for these parts, and the figures below are typical of what they state. Board and system makers then set their own supply periods on top, usually shorter than the processor’s.

Treat these as planning figures, confirm them for the exact part, and keep a record of the processor stepping, board revision and BIOS on every system. Our explainer on how long NVIDIA Jetson is supported covers the Jetson side. Long availability is also why a slightly older embedded part often beats a brand-new consumer one in a design that will be made for years.

Before the brand comes the instruction set, and it is the first real fork in choosing an embedded processor. Most industrial computing runs on x86, with the broadest operating system and application compatibility and strong single-thread performance. Arm takes the other path, with more performance per watt and highly integrated SoCs, which is why it dominates compact, sealed and battery-powered devices and why Jetson pairs Arm cores with an NVIDIA GPU.

RISC-V is the one to watch. It is an open instruction set managed by RISC-V International, and it already runs in many microcontrollers and as management cores inside larger chips. Linux-capable RISC-V applications processors are appearing, but industrial boards with long-term software support remain rare, so for most products today the choice is still x86 or Arm. Our comparison of x86 and Arm covers that choice in depth.

Start with the workload, then check the choice against the physical and commercial limits of the system. The table maps common workloads to the processor classes that usually suit them.

Then check the power. A processor’s base power, its turbo limits and the cooling of the enclosure decide whether it will hold its performance; our guide to TDP explains the figures. Finally, check the boards and systems: our industrial computers show the processors in use, and a processor is only as available as the boards and computers built on it, and our guide to choosing an embedded motherboard covers that step.

These boards and modules show one example of each class. We fit memory and storage, configure the BIOS or boot loader, image the operating system and application, and test each system before it ships.
