After Apples announcement of M1, I feel like it is mandatory for such a laptop test to discuss power per watt and for how long you can game on the 11 vs 12th gen processor. I also feel like it is worth mentioning that 12th gen laptop is priced ~ $150 over the 11th gen. If you're coding against an online build system and 11 last an extra hour (or whatever), it's a no-brainer to stick with the old one.

You can't game on M1 or Mac AFAIK

With MacOS probably never in a good way as MacOS doesn't support standard graphic APIs (Vulkan)

In the near future you might if you install linux.

Using box64 for amd64 translation and steam proton for windows translation if necessary.

Lowering the power of an intel/AMD CPU enough to passively cool it would yield way more performance than currently commercially available arm CPUs. (Obviously excluding CPUs that aren't purchasable like Apple's)

Does that include the Apple M1 / M2 lines?

I have absolutely no reason to believe Apple will ever sell those to third parties. I've edited the comment to clarify.

In a laptop, I care far more about battery life and the fan noise. However, Intel 12th gen is only able to pull these impressive performance feats due to very high turbo boost clocks.

It's not that Intel is bad, it's still pretty great but in the age of M1 I wish Intel released a processor with similar power consumption.

I use my Intel i5-1240p with turbo boost disabled when on battery. Here's the geekbench with TB disabled. https://browser.geekbench.com/v5/cpu/16497299

Since the keyboard is replaceable you could make your own and also sell to other like-minded people?

That's quite a bit more expensive than complaining on HN, or just buying a Lenovo

The HP EliteBooks (and the new Dev One Linux variant) also have trackpoints.

Just in case anyone's interested in making their own though, I've seen a few DIY trackpoint projects over the years (mostly on custom mechs, not laptop keyboards though). Here's a writeup on one: https://edryd.org/posts/tp-mk/

Well then you are minority. I want a portable desktop, speed I can bring with me without lugging my 35lb liquid cooler setup with its 4x140mm radiator. I want something compact and sexy but insanely fast when I “dock” it

The success of the thin-and-light segment, and the MacBook Air in particular, suggests that OP is very much in the majority.

Then make that a segment and stop enforcing your unrealistic expectations on the rest of us finally.

Oh wait, it already is but you don’t. I routinely engage in comment sections where a highly juiced up desktop CPU is derided for it’s “heat output” and other such nonsense.

I've played with an AMD 6800u laptop and I would say it's the ideal x86 laptop chip right now. Normal usage at the 12w mode or light gaming at 20w mode was super impressive. Even though 12th Gen Intel chips have made great performance gains Intel is still relying on unsustainable high turbo boosts to get the benchmark numbers. I just recently stumbled across these two otherwise identical laptops. https://psref.lenovo…

Since this is Hacker News and a lot of people here runs Linux, I want to remind everybody to hold your horses before you tested Linux on these machines. The machine that I'm currently using comes with a Ryzen 6800H CPU and LPDDR5-6400 RAMs, made by Lenovo. On Linux, the builtin keyboard don't work because of IRQ problems (See [1], a fix is also available at [2]), and it constantly spams out "mce: [Hardware Error]: Ma…

Note that this is more of a motherboard issue than a CPU problem. The fix is basically to disable a previous fix for some other buggy hardware.

Plenty of people have new Ryzen laptops that work just fine.

My AMD Gen 1 has been nothing but trouble under Linux.

But it's not CPU, it's Lenovo. Lenovo has terrible firmware team.

Exactly. Not just 1 model but you can compare identical ThinkPad models as well and AMD versions have significantly better battery life. Not only that, even last year's identical models with 11th Gen Intel CPUs have better battery life than their new 12th Gen models. So Intel's power efficiency actually decreased compared to last year, even though they introduced the hybrid architecture. In some instances Alder Lake…

These numbers are usually lower in real life There are data sheets and then there is real life. People were raving about AMD laptops before. I got a ThinkPad T14 AMD with a 4750U. The stated psref battery life is MobileMark 2014: 14 hr, MobileMark 2018: 11.5 hr. In practice that was more like 7 hours on Windows (with a mild workload) and 3 hours on Linux. The CPU performance was merely ok and I could get the fans blo…

That does not match my own experience with a very similar t14s equipped with same CPU. I get much better battery life than 3 hours on Linux even with moderate workload (compiling, browsing, etc.). I often use it on the go and it’s been pretty great.
