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.

Don't forget 12th gen Intel CPUs have a lot more cores than 11th gen Intel CPUs. That's where the significant benchmark improvements are coming from. Unfortunately though, these often don't reflect the real world use case. Having more cores isn't going to improve the day-to-day performance very much. The new efficiency cores probably improve battery life though

I agree, but than you have corporate compliance installing an insane amount of Spyware on your device so that a 2021 XPS 13 Dell with a gen 10 Intel is out of battery when only using word within the hour.

Fans spinning all the time and no way of disabling this madness.

Nearly the same for my Mac colleagues. They maybe get 2 hours out of their M1 MBPs unplugged.

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…

Within a year the kernel should support proper Power management on these new AMD systems. I have a year old 5800H that went from 3 hours to 11 hours battery life in typical use, just due to kernel version updates. It's like a new system.

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.

Let’s remember AMD was absolute garbage for like 10 years until around 2016, when they finally bounced back. And they were getting closer and closer to bankruptcy, having to flog the silver - their fabs and even their campus. I’d say the Zen design and tsmc saved them (or Lisa Su and Keller).

Intel is in a better position financially than AMD was, and could catch up again. I tend to think it depends a lot on the organization and the people.

I think for those who primarily work on AC and do not mind increased power draw, 12th Gen is a good choice. As a software developer, I appreciate a few seconds shaved off here and there. With good thermal design, 12th Gen laptops can be silent and cool (I've never heard my MSI GT77 spin up the fans, unless I tell it to with a dedicated hardware button). I understand that people have different use cases and for lot of customers laptops need to be lightweight. I'm okay with the bulk and weight.

Just ran Phoronix Linux kernel compilation test (defconf), I get 74.68 sec on my laptop, on par with desktop Intel Core i7-12700K, but I can carry my "desktop" around. :) In comparison, Apple M2 result is 416 sec, AMD Ryzen 9 5900HX is 103 sec. It's not much, but it's compound gains if you compile and test a lot.

I went from saying, "if only they had an AMD" to getting a different machine in ARM and now im saying "if only they had ARM". I never realized how much heat, vibration, air blowers negatively affected me before. A framework laptop with some type of ARM or ARM-like cpu could do a lot with the space savings on cooling.

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…

I have been using a 6800U on Linux for the past two weeks. With kernel 5.18 almost everything is supported out of the box. The few issues I have:

- Kernel logs show that the GPU driver crashes from time to time. When it happens the screen freezes for a few seconds but recovers.

- HVEC hardware decoder gives green artifacts on VLC using VA-API.

- It seems not to support advanced power management, on battery the CPU will happily boost to 4.7 GHz which in my opinion makes little sense. AMD has been steadily pushing work related to power management so I expect it to improve. As it stands total power consumption on battery averages 5.1 W.

I had similar numbers on my i9 MBP. Last week, on my M1 MBP, I spent an hour in a Teams (Electron!) call while off power and battery went from 99% to 96%. Intel needs to match that to even be in the game for portables IMO.

The M1/M2 laptops are so above and beyond anything from AMD and Intel that it’s almost a joke. If Apple was really smart and had enough supply, it could drop the price down a couple of hundred dollars and completely take over the laptop market.

It's already way cheaper than comparable windows machines

Price isn't the thing that keeps most people I know away from Macbooks (after all, it's the employers/business expense). I'm sure many people would like an M1 machine for the efficiency but the software is simply not ideal.

If they invested in contributing Linux drivers they'd probably be able to takeover the market for developers. Asahi is slowly improving, but it doesn't feel ready yet to be someone's sole daily machine.

Ultimately my M1 MBP sits on the shelf collecting dust, except for occasional testing. My smaller and lighter Intel laptop already gets 8 hours of battery life which is more than enough for me, and has perfect Linux support.

Although CS:GO is an FPS that can run on a potato, the GPU results are interesting. But I would love to see a Framework laptop with a Ryzen APU (I have a Lenovo with a 5700U and it is nothing short of amazing, even though it’s almost two years old by now). Provided they can do Thunderbolt, that is (I rely on that for a number of things).

I am writing this from a M1 MBP with screen at extra full brightness (using vivid) and I can say I get way more than 2 hours from it.
