Intel64 Family 6 Model 142 Stepping 10 Here

The number distinguishes the specific microarchitecture within that family. For decades, each new "tock" or "optimization" received a unique model number. Model 142 (0x8E in hexadecimal) is the definitive marker of the Ice Lake microarchitecture. Ice Lake was a significant milestone: it was Intel’s first high-volume microarchitecture to be manufactured on the 10nm process node after years of delays with 10nm. More importantly, it introduced the Sunny Cove core, which brought deep changes to the execution engine, wider allocation, and enhanced security features.

Family 6 Model 142 Stepping 10 represents a turning point. It was the chip that finally moved the industry past the 14nm era. It brought AVX-512 to the mainstream laptop (before later architectures removed it for power reasons). And in its stepping 10 maturity, it offered a glimpse of what Intel’s 10nm process could have been from the start: stable, performant, and efficient. intel64 family 6 model 142 stepping 10

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. Before delving into the specific numbers, one must understand the code. The Family 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. Ice Lake was a significant milestone: it was
