To understand this processor is to understand how Intel’s engineering teams iterate on a design, how they distinguish between major architectural leaps and minor production tweaks, and how a single identifier can unify everything from a laptop chip to a server processor.
The technical identifier represents a specific processor revision within Intel’s 14nm microarchitecture lineup, most commonly associated with 8th and 10th Generation Intel Core mobile processors.
This designates the long-standing P6 microarchitecture lineage, which includes nearly all modern Intel Core processors from the early 2000s through the present.
"Who are you?" the system asked, querying the CPUID. intel64 family 6 model 142 stepping 10
In the old days, trying to put a powerful chip in a skinny laptop resulted in a burning lap and a dead battery. But Model 142 was engineered differently. It had a Thermal Design Power (TDP) of just 5 to 7 watts. It sipped electricity like a hummingbird sips nectar, allowing fanless designs or incredibly quiet laptops like the MacBook Air or the Dell XPS 13 to run cool and last all day.
If your system displays this identifier, you are likely using one of the following popular mid-to-high-range mobile processors:
Why is this essay relevant today? Because Intel continues to use this scheme. Subsequent families—Tiger Lake (Model 144), Alder Lake (Model 151), Raptor Lake (Model 183)—are all still Family 6. The identifier persists as a low-level handshake between the silicon and the firmware. To understand this processor is to understand how
Stepping 10 ensured that these features operated reliably. Early Ice Lake steppings reportedly had issues with certain AVX-512 power management states and memory controller stability; stepping 10 represented the mature silicon where those kinks were ironed out.
Thus, "Stepping 10" is a quiet certification of quality. It tells the engineer that this processor has survived the crucible of production feedback, that its thermal and frequency curves are well understood, and that it will behave identically to other stepping 10 parts across thousands of units.
Systems with this CPU typically offer a balance of power efficiency and burst performance: "Who are you

: The broad architecture family for most modern Intel Core chips.
Before delving into the specific numbers, one must understand the code. The number (6) is the most stable element. Since the introduction of the P6 architecture in the mid-1990s, nearly all modern 64-bit Intel processors (Core, Xeon, Atom) have belonged to Family 6. This number signals a common instruction set base (Intel64) and fundamental design lineage. If you see Family 15, you are looking at the NetBurst architecture (Pentium 4)—a relic of a different era.
To a software developer or system administrator, the stepping number is not trivia. For example, a hypervisor like VMware ESXi or a Linux kernel might include specific workarounds for "Intel Family 6 Model 142 Stepping 2." If you attempt to run that same software on Stepping 10 without updated microcode, the system may still apply unnecessary, performance-degrading patches. Conversely, a stepping-specific bug in the RDRAND instruction or the power management unit might only affect steppings before a certain threshold.
