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 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.

Irony being, one of the biggest benefits for me of the M1 power consumption is that it can run quiet and smooth even with all the corporate spyware on there. It can even run MS teams along side that and docker too which also permanently consumers 100% of one core, while still staying completely silent.

It's crazy to think you have these opposing teams of engineers, the Apple ones working away to optimise like crazy to reduce power consumption and the compliance software teams thinking up new ways to profligately use more.

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.

This may have been true when the M1 was just released, but the gap both in performance and power consumption is shrinking. And that's with the competition still being one process node behind.

I'm developing in rust for $dayjob and I absolutely hated it until I got a M1 mac. CPU speed (including single core speed) absolutely made the difference. The compilation speed crossed that threshold between "a little pause" and getting distracted doing something else while waiting for a little incremental compile

I'm also developing in Rust, with a 12th gen i7-1270P. It's an absolute beast; I'd say it's on the range of 2x speedup vs my previous laptop (11th gen i7).

I have no idea about power consumption yet (the laptop is a couple weeks old). On light load, the laptop easily crosses the 8h mark but it won't, certainly, when grinding rust compiles. The M1's power efficiency is on a different league.

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…

These ACPI tables are commonly broken. Who creates and tests them?

I assume the M1/M2 performance versions are much more expensive (very large L1/L2 caches, see Ryzen vs Ryzen X3D performance, and that only increases cheap L3 cache) than AMD processors. Apple can afford this I assume with high end laptop and their margins from owning the supply chain. Apple has the benefit of not telling and you can't buy an M1 (?). I would be interested about production costs of Ryzen vs. M1/M2 processors, any sources?

Note that Cinebench R23 (the main CPU benchmark we use) runs for 10 minutes, so it’s a measure of sustained performance. Boost (PL2) is typically 30 seconds or less with a long period after that of staying at the PL1 limit.

I agree that 12th gen can sustain good performance given decent cooling. However, the issue is still heat.

It could be fun to have a `lap benchmark`. That is can you keep a laptop on your lap while it runs Cinebench R23 for 10 minutes? With TB disabled, I can.

Why is Docker's VM not idling?

Recently discovered that Infosec has now mandated that all laptops have sleep disabled (the reason given is to be able to do endpoint patching). ¯\_(ツ)_/¯

So I'm faced with having to log out and power off every day or suck up the cost of keeping the laptop on. /r/maliciouscompliance, here I come I suppose.

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 orga…

Jim Keller?

IC: A few people consider you 'The Father of Zen', do you think you’d scribe to that position? Or should that go to somebody else?

JK: Perhaps one of the uncles. There were a lot of really great people on Zen. There was a methodology team that was worldwide, the SoC team was partly in Austin and partly in India, the floating-point cache was done in Colorado, the core execution front end was in Austin, the Arm front end was in Sunnyvale, and we had good technical leaders. I was in daily communication for a while with Suzanne Plummer and Steve Hale, who kind of built the front end of the Zen core, and the Colorado team. It was really good people. Mike Clark's a great architect, so we had a lot of fun, and success. Success has a lot of authors - failure has one. So that was a success. Then some teams stepped up - we moved Excavator to the Boston team, where they took over finishing the design and the physical stuff, Harry Fair and his guys did a great job on that. So there were some fairly stressful organizational changes that we did, going through that. The team all came together, so I think there was a lot of camaraderie in it. So I won't claim to be the ‘father’ - I was brought in, you know, as the instigator and the chief nudge, but part architect part transformational leader. That was fun.

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.

How much corporate garbage on it, though?

Out of curiosity, and aside from Teams which I'm already sadly familiar with, what software is it that you're talking about? Company I work for was just bought by some megacorp, but I'm still using my own 2019 13" MBP for now.
