Take it with a grain of salt. Other reviewers such as Hardware Canucks [1] have mentioned that they have not been able to get such long hours. Their numbers are closer to 15 hours.

Battery life is based on playing a 720p video file so most of the expended power will be in the video decoder and screen not the actual CPU. It's also dependent on the battery size in the laptop being tested so pretty much impossible to compare on any like for like basis.

I'd love to know how long the Acer Swift Go 14 with the AMD Ryzen would have lasted with the same battery size.

The Acer Swift Go 14 has a battery with 53 WHrs and for e.g. the Asus Zenbook S 14 has a 72 WHrs battery. Would this mean the Ryzen Laptop could have lasted ~1.35 times longer than it currently did i.e. 21:15 hours instead of 15:40?

But will the CPU last more than 2 months

Honestly, I'll believe it if I have one in my hands.

So far I have a Surface Laptop 7 with the Snapdragon which has blown me away in terms of battery life. I'm talking 10+ hours watching video on full brightness.

And I'll happily sacrifice 50% of that for a better screen and a more powerful GPU.

The worst part today Windows 11 ARM is that on WSL `brew` is not supported.

The most interesting part to me is the Cyberpunk 2077 performance compared to Snapdragon and AMD. It's surprisingly good and considering Strix Point pricing, Intel might be the next sure bet for the Steam Deck 2. If not with this, then maybe with Panther Lake (Intel 18A).

Ah... can't wait to see the next generation of "macbook killers".

... and Microsoft (probably Linux too) will throw it all away with some tiny coding mistake.

Where are all those people who for years (or since M1) were claiming that x86 is dead because ARM ISA (magically) offers significantly better energy-efficiency than x86 ISA.

Of course they ignored things like node advantage, but who cares? ;)

Meanwhile industry veterans were claiming something different and turns out they were right

Asking which - x86 or ARM is faster/more energy eff is like asking which syntax (letters) is faster - syntax of Rust, Java or C++?

And same as with CPUs - everything is up to the implementation - compiler, runtime/vm, libraries, etc.

I mean, any laptop could have 7 days worth of battery life with a big enough battery
