This is not true. AMD CPUs do not include NVME controllers for example. There probably are more things AMD does not do on the CPU itself.

I meant the controller that manages the NAND cells, I assumed it would be called NVMe controller. Essentially the IC that the "NVMe controller" in your image talks to.

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/

No they don't neither do the Dells, these do not have negative inertia because IBM patented that.

And yes, there are DIY TrackPoint keyboards, I have a TEX Shinobi.

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 d…

intel's comet lake or whatever is pretty comparable to M1 imo

The AMD offerings are much closer to M1 although they're not yet on TSMC 5nm so they don't quite match it. It's a historic event. Intel was #1 in laptops for an eternity. Even when the Pentium 4 was being outclassed by AMD Intel still kept the crown in mobile. This time around they first got overtaken by AMD and then by Apple and are now #3. Puts into perspective how huge of a miss their process node fail was.

The AMD offerings are still very far from the M1. Try comparing the 6800U to the now 2-year old M1 in Geekbench. The M2 widens the gap even more.

The Ryzen chips are already clocking over 3 GHz, so there isn't much more scaling from power left. That's why 5nm Zen4 probably won't move the needle too much.

Compared with the Phoronix Suite, on Linux, just today: https://www.phoronix.com/review/apple-m2-linux/15.

Surprising results. Definitely not in the "very far" range.

Just yesterday, I ran a few CPU benchmarks to compare my new System76 Lemur Pro (12th Gen i7-1255U) against my older ThinkPad X1G7 (10th Gen i7-10710U). Both are ultra low-power processors, so it's a fair comparison. Here are the results: https://mstdn.io/@codewiz/108785771608278574

Maybe it's my imagination but it seems like more cores isn't helping performance as much? Does it seem every core after 6 cores is about 1/2 or 1/3rd the performance gain?

From your link: "Even under demanding multi-threaded workloads, the M2 MacBook Air was not nearly as warm as the other laptops tested"

Keep in mind the 6850U you're comparing against has a fan too. Notebookcheck says it has a 40W turbo on the gen 2 model, and the gen 3 Intel version has a 28W sustained boost. An M2 uses around 20W.

Also, a lot of those benchmarks are showing all x86 CPUs with a 3x+ lead, which indicates software optimization problems. Geekbench 5 is optimized for both arm64 and x86 and shows the M2 ahead of the 6800U. There are also just broken results like the LC0 test where the M1 is substantially faster than the M2. Overall, your results don't seem very valid.

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.

Im generally not that concerned about power consumption. My laptop almost never is unplugged for more than a couple hours. I understand that there are many others who don’t use their computer like I do, but personally the only negative effect of power consumption is that it costs an extra $10 a year.

But are you concerned with heat and fan noise?

So.... is the Framework laptop with a 12th Gen core noisy or not? Is it quiet most of the time? Do the fans become noisy during a compile or benchmark? Does it remain relatively cool? What are people's experiences with these laptops? My primary use would be C++ development with frequent large multi-core builds.

I think not everyone is going to be sensitive to this, but apart from battery life, it's super nice having a computer that's not spewing out heat or running the fans loudly.
