Can You Save Power by Sticking with an Older PC?

The question is whether an older PC (from 2013 with a 4th-gen Intel CPU and 10-series NVIDIA GPU) uses less power than a newer one (from 2022 with a 12th-gen Intel CPU and 30-series NVIDIA GPU). Let’s look at how they compare and what it means for you.

Power Use: Old vs. New PC

When Idling (e.g., browsing, streaming): Both systems use about the same power—roughly 30-60 watts. The old PC might be slightly lower, but the difference is tiny, like a few cents a day.
When Working Hard (e.g., gaming, video editing): The new PC uses way more power—250-350 watts compared to the old PC’s 100-150 watts. That’s 2-3 times higher!

Cost Difference

Imagine you game or work hard for 4 hours a day. The new PC might use 150 watts more than the old one. At $0.15 per kilowatt-hour (US average), that’s about $0.09 extra per day—or $32 a year. If you use it less or electricity is cheaper where you are, the savings drop even more.

Efficiency and Performance

Light Tasks: For basic stuff like web browsing or coding, both PCs are close enough in power use that it barely matters.
Heavy Tasks: The new PC is much stronger and faster. It uses more power, but it’s also more efficient—it gets more done per watt. For example, the new GPU is 2-3 times faster than the old one but only uses about twice the power. If your old PC struggles with modern games or big projects, the new one might finish faster and offset some of that extra power use.
Old PC Limits: If your 2013 setup can’t keep up (e.g., slow multitasking or laggy games), the new PC’s speed could be worth it.

Bottom Line

Yes, the old PC saves power—especially if you do heavy tasks like gaming infrequently. You could save $20-50 a year on electricity, depending on how much you use it.
But performance matters too. If the old PC can’t handle what you need, the new one’s efficiency and power might make sense, even if it costs a bit more to run.
What to Do: Stick with the old PC if it works for you and you want to save a little cash. Upgrade if you need the extra oomph and don’t mind the higher power draw.

Does a Photon Have a Wave Function?

Yes, a photon does have a wave function in the context of quantum mechanics. The wave function, typically denoted as $\psi$, describes the quantum state of a particle, including its probability distribution in space and time. For a photon, which is a quantum of electromagnetic radiation, the wave function is
