Comparing Today's Modern CPUs To Intel's Socket 478 Celeron & Pentium 4

Lastly, here are the power consumption metrics for the Celeron and Pentium 4 configurations and a few of the modern Intel systems.

As a reminder, the Celeron D 320 2.4GHz has a 73 Watt TDP and the Pentium 4 C 2.8GHz has a 69.7 Watt TDP. The Atom Z3735F has a 2.2W SDP, the Celeron N2820 has a 7.5 Watt TDP, and the Broadwell Core i3 5010U has a 15 Watt TDP. There's also the graphics and disk differences, but long story short, the power efficiency of Intel x86 CPUs have improved dramatically over the past decade and further.

The Broadwell Core i3 5010 delivers over 4x greater performance-per-Watt than the old NetBurst CPUs while the Bay Trail Z3735F was almost 3x better.
