Intel64 Family 6 Model 140 Stepping 1 Genuineintel 2803 Mhz

Stepping is a minor revision. Stepping 1 for Model 140 represents the A0 or A1 silicon revision, which is typically the first production mask. For Alder Lake-N, Stepping 1 is the initial release. Later steppings (e.g., Stepping 2 or 3) might fix errata or improve power efficiency, but Stepping 1 is common in early batches of mini-PCs, thin clients, and laptops.

This is where identification gets precise. Model numbers distinguish specific designs within a family. Model 140 corresponds to the Alder Lake-H / Alder Lake-P (mobile) or Alder Lake-S (desktop) series, but only certain steppings.

After cross-referencing with Intel’s public architecture spec update documents:

However, there is a twist. Most common Alder Lake desktop processors (e.g., i7-12700K, i5-12600K) use Family 6 Model 151 (0x97). So where does Model 140 fit?

Model 140 is typically found in:

Further evidence: Intel’s Linux kernel patch database lists Model 140 as “Alder Lake-N” – a variant featuring only Gracemont E-cores (no P-cores), sold as Intel Processor N-series (e.g., N100, N200, N305). Yes, this means your "Intel64 Family 6 Model 140" could actually be one of the newer, all-E-core chips.

Intel’s Family 6 has lasted almost 30 years. Model numbers will continue to rise, but the identification scheme remains. Will we ever see Family 7? Intel has occasionally teased a "Family 7" for completely new architectures (e.g., if they move to a fully post-x86 ISA), but as of 2025, Family 6 continues with Arrow Lake (Model 0x on the horizon).

For your Family 6 Model 140 Stepping 1 processor: expect full software support until at least 2030–2032. It will not run future AI-heavy Windows features well (like Copilot+ local models), but for standard computing, it has years of life left.

| Specification | Detail | |---------------|--------| | Cores | 12 cores (4 Performance-cores + 8 Efficient-cores) | | Threads | 16 threads | | Base P-core | 1.7 GHz? Wait – Correction: The P-core base is actually 1.7 GHz for i5-1240P, but the CPUID string reads "2803 MHz". This discrepancy arises because CPUID reports the maximum nominal frequency of the fastest core under base conditions. In Alder Lake, the E-core base clock is 2.8 GHz? No – re-checking Intel’s spec: i5-1240P P-cores base = 1.7 GHz, E-cores base = 1.2 GHz. So why 2.8 GHz in CPUID? | | Explanation | Many Windows reporting tools show the maximum base frequency of any core cluster after applying manufacturer-defined multipliers. In this case, the string likely comes from a desktop Alder Lake SKU: the Core i5-12400 (desktop) has base clock of 2.5 GHz, not 2.8. Or a Core i3-12300? No. Alternatively, it could be an Intel Pentium Gold 8505 (1P+4E, base 2.8 GHz). But the 2803 MHz exactly matches Intel Core i5-1245U (vPro) and i5-1235U with 2.8 GHz base on the performance cores. | intel64 family 6 model 140 stepping 1 genuineintel 2803 mhz

After cross-checking multiple CPUID databases (CPU-World, 7-Zip benchmark repo, Linux cpuid dumps), the most frequent hit for "Family 6 Model 140 Stepping 1 2803 MHz" is the Intel Core i5-1235U (Alder Lake-U, 15W base TDP). The 1235U has:

Conclusion: The string belongs to a mid-to-low power mobile Alder Lake chip, most likely the Core i5-1235U or i5-1240P. For this article, we’ll focus on the i5-1235U as the representative CPU.

In the world of x86 architecture, precise identification of a central processing unit (CPU) goes far beyond marketing names like “Core i7” or “Pentium.” For operating systems, debuggers, and firmware developers, a CPU is defined by a triplet of numerical identifiers: Family, Model, and Stepping. One such string—Intel64 Family 6 Model 140 Stepping 1 GenuineIntel 2803 MHz—refers to a specific, recognizable generation of Intel processors. Analyzing these parameters reveals a 12th generation “Alder Lake” chip, a hybrid architecture that marked a significant shift in Intel’s design philosophy.

Architecture: 10nm SuperFin | Cores/Threads: 4 Cores, 8 Threads | Base Clock: 2.8 GHz | Boost Clock: Up to 4.7 GHz Stepping is a minor revision

The final two components of the identifier describe the processor’s operational and brand authenticity. 2803 MHz (approximately 2.8 GHz) is the base clock frequency. It is crucial to note that this is not the maximum boost clock. For an Alder Lake CPU, the maximum Turbo Boost frequency can be significantly higher—often 4.4 GHz to 5.0 GHz or more, depending on the specific SKU and thermal conditions. The 2.8 GHz base clock is typical for a mid-to-high-power Alder Lake desktop processor (e.g., Core i5-12600 or i7-12700) or a high-performance laptop part (H-series). This base frequency represents the guaranteed speed under sustained, all-core workloads within the processor’s specified thermal design power (TDP). The wide gap between base and boost clocks is a hallmark of modern dynamic frequency scaling.

GenuineIntel is a simple but essential vendor string. It confirms that the CPU was manufactured by Intel Corporation and is not a third-party clone or a virtualized identifier. This string is hardcoded into the CPU’s read-only memory and is used by the operating system to load vendor-specific patches, optimizations, and microcode updates. During the 1990s and early 2000s, “GenuineIntel” was crucial for distinguishing authentic x86 processors from competitors like AMD, Cyrix, or VIA, which would report “AuthenticAMD” or other strings. Today, while the market is duopolistic, the string remains for legacy compatibility and diagnostic clarity.

This specific trio of numbers is the most critical part for identifying the exact generation and revision of the chip.
