Mhz — Intel64 Family 6 Model 140 Stepping 1 Genuineintel 2803

This is the base clock frequency (not boost). 2803 MHz = 2.8 GHz. However, Intel CPUs often have a base clock lower than the advertised nominal base; rounding occurs. In practice, 2803 MHz points to a nominal 2.8 GHz base frequency.

A common question: “2.8 GHz seems low compared to older 3.5 GHz CPUs. Is this processor weak?” intel64 family 6 model 140 stepping 1 genuineintel 2803 mhz

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 is the base clock frequency (not boost)

When passing this CPU to a VM (QEMU/KVM or Hyper-V), use host-passthrough to expose the hybrid topology correctly. Using a generic qemu64 CPU profile will cripple performance. rounding occurs. In practice
