At 2.8 GHz base (P-core) and 4.4 GHz turbo, how does it stack up?
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: intel64 family 6 model 140 stepping 1 genuineintel 2803 mhz
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.
Run:
cat /proc/cpuinfo | grep -E "model name|cpu family|model|stepping|cpu MHz"
Or use lscpu | grep -i "model name" – but beware that lscpu older than 2.39 may show “Model: 140” without decoding.
A common question: “2.8 GHz seems low compared to older 3.5 GHz CPUs. Is this processor weak?” However, there is a twist
Answer: Clock speed is not comparable across architectures. A 2.8 GHz Golden Cove core (P-core) can outperform a 3.8 GHz Skylake core (6th Gen) by 30-40% due to higher IPC.
This CPU will likely be relevant through 2028 for low-end notebooks and embedded systems. However, driver support for the iGPU may improve with Linux kernel 6.12+, so keep the OS updated. so keep the OS updated.
