Don't forget laptops. Intel has been terrible on laptops due to their lack of efficiency. AMD has been wiping the floor with them for years now.

2024 is the first year that Intel has released a laptop chip that can compete in efficiency. I hope Intel continues to invest in this category and remain neck and neck with AMD if we have any hope of having Windows laptops with decent battery lide.

I doubt most people actually care about efficiency in a laptop. My wife is my anecdotal example. She's had a mac for years but refuses to give Apple one more penny because they've been awful - had to replace her previous laptop motherboard 7 times until we finally had to sue Apple in a class action which resulted in them sending her current 2015 MBP, which has now aged-out of MacOS updates. Sucks that this computer is now basically a paperweight.

Anyway, in my questions for her about what she really cares about in a new laptop, power efficiency was not a concern of hers. She does not care about efficiency at all. All she cared about was a good enough screen (2560x1440 or better), and a fast CPU to run the new Photoshop features, and the ability to move it from one location to another (hence the need for a laptop instead of a desktop). I'd wager that for most people, the fact that it's a portable computer has nothing to do with how long the battery lasts away from an outlet. She can transport the computer to another location and plug it in. There are very few situations that require extended use away from an outlet, and even in an airplane, we often see 120V outlets at the seats. There's really no use case for her that puts her away from an outlet for longer than an hour or two, so efficiency is the least of her concerns in buying a new laptop.

So we went with a new Dell laptop with the Intel i9-13900HX, which beats the Apple M4 Max 16 Core in terms of overall performance in CPU benchmarks. I would have looked at an AMD based laptop, but the price on this Dell and the performance of the i9 were great, it was $999 on sale. It's got a decent enough screen, and we can easily upgrade the RAM and storage on this laptop.

I doubt she'd even care if the new laptop didn't have a battery at all, so long as she can easily stuff it in a bag and carry it to another location and plug it in. I feel the exact same way, and I recently bought a new (AMD based) laptop, and power efficiency was not a thing in my decision making process at all. The battery lasts a few hours, and that's plenty. I don't get a hard-on for battery life, and I'm not really sure who does. Are these people dancing around with their laptops and simply can't sit still and plug it in?

Efficiency and performance are heavily correlated in portable devices. You only have a certain TDP that you can utilize before the device throttles due to a lack of heat dissipation. The more efficient a CPU you have, the more you can accomplish before you hit temps that will affect performance.

I have plenty of people who care. Why? They always forget to plug in their laptop and then they want to open it and it's dead. Not to mention, x86 Windows machines do a poor job going to sleep.

Handed the wife M2 Macbook Air and she's thrilled how little she has to plug it in. She goes weeks between charges sometimes.

Not trying to invalidate or lessen your complaint (which I completely agree with) but want to make sure you are aware of OpenCore Legacy Patcher. It's a little hacky by nature but can give some extra life to that machine: https://dortania.github.io/OpenCore-Legacy-Patcher/MODELS.ht...

yeah, I looked at it, but this MBP has a speaker that died, the SD card reader died a long time ago, had to replace the battery, it's slow, and it doesn't really play nicely on the SMB network, etc, etc. I'll be glad when it's gone. And OpenCore patcher seemed like a lot of hassle to keep putting up with this machine. Thanks for suggesting it though.

There is another angle at power efficiency: my work laptop is so bad, moderate load makes the fan spin and higher load creates a very annoying noise due to the cooling needs. All these while performance is far from stellar (compared to my desktop).
