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…

How is 12th gen compared to 10th gen, in your experience? My XPS 13 on a 10th gen i7 just becomes absolute syrup on battery, even if I put it in high performance mode.

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.

What I don't like about framework notebooks is that they seem to be mostly interested in speed, which is why they seemed to choose these P-series CPUs. With a notebook, I'm much more interested in energy consumption (how long can I work off grid), emissions like fan noise and the like. Why no U-series CPUs?

The U and P series parts are actually the same dies on 12th Gen, but binned. If you set the Power Mode to Best Power Efficiency on Windows or the equivalent power limiting in Linux, you can make a P behave pretty similarly to what a U would (with the Intel DTT settings we used).

Isn't it the H and P series that use the same die, while the U series is a much smaller die (2 instead of 6 P cores)?

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 don’t like that we call it 12th Gen Intel. It would be more correct to just call it the 12000 series Intel.

Intel didn’t change CPU generations from 6000-10000 series, they’re all the same generation. Just because the years advance and they refresh their products with increased product numbers doesn’t mean that they’re a new generation of products.

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…

There is a big improvement from the 4000 series to the 6000 series.

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…

I've been running Linux on a Lenovo with a 5800h for almost an year with zero issues.

I did have plenty of freezes on my old 2500u machine though. Was very disappointed. Thankfully, those days are long gone

I’m rather disappointed in 12th Gen for mobile. I have a AMD 5800h Lenovo laptop and a 12700 Dell. The dell stutters, fans spin, etc. the Lenovo is just rock solid and fast. Never stutters or slows down. Fans spin up only when playing games. I wish framework would do an AMD laptop. But Linus put them in touch with AMD and they done nothing.

It can depend more on the graphics card(s) and the chassis type than the CPU. For example if the Lenovo is a P15 and you’re comparing it to a Dell Latitude, then yeah duh.

The Lenovo Laptops I have are Legion 7 2021 (5800H / 3070), X1 Extreme Gen 1 (8th gen / 1050ti) vs Dell XPS 15 (12700 / 3050ti)

Both Lenovos are rock solid, not laggy or stuttery.

But I had a Dell XPS 15 (2020) model from work, I gave it back because idling in Windows made the fans spin...

I got a newer Dell XPS 15 (2022) for work (new job) and its great, but its stuttery and the fans spin under light loads. (the screen is amazing tho, i love the screen)

Building a new laptop from scratch is time-taking and costly. So Framework may rightly be spending their time on optimising product, reducing cost and reaching more countries.

Linus said he put them in touch and they haven't even spoken to each other. It's going to take time, but they aren't even engaging at the moment...
