What is the memory bandwidth to the main CPU cores (not the "neural engine")? Is it really 120GB/s like they say in the spec sheet[0]? That's 20GB/s faster than the top dual-channel DDR5 desktops, which makes me think there might be some fine print I'm missing.

Personally I've been a huge fan of my Framework 13, and am planning at some point to swap out the mainboard with the new one they released — it's pretty nice that you can do that (and they sell a desktop case to put the old mainboard in, so you end up with a faster laptop and a spare desktop afterwards!). Battery life is the main downside, although it doesn't bother me too much — running manufacturer-supported Linux…

Yeah, I love Framework (disclosure, I invested in their community funding round) and I pre-ordered the desktop and have strongly considered upgrading my Intel laptop of theirs to an AMD mainboard (or just getting a whole new unit since I'll have to get new RAM and would like the higher DPI screen) and compared to other Windows or Linux options right now, I think they are pretty strong for thin and light HOWEVER I wou…

I would love it if they made it easy to split 16x PCI-e 5 16x/8x/4x slots into gen3 or gen4 breakouts.

The chips may not have the lanes, but they have the bandwidth if only 10GbE / 4xm.2 / storage controllers could plug in. I wonder if power is an issue.

You’re making it seem like they’re hiding that information under a footnote. The real text on the page, which is quite visible, is: > Up to 23x faster than fastest Intel‑based MacBook Air And right next to it: > Up to 2x faster than MacBook Air (M1) The footnotes are there to expand on the conditions of the measurements. So not exactly misleading. On the contrary, it seems to me they’re quite clearly saying “if you h…

"Up to" is still doing a lot of work there. What kinds of workloads are we talking that get the big numbers, and what can we realistically expect on real workloads? I'm reminded of 90s advertisements in which the new G3 processor was supposed to be so many times faster than the Pentium or even Pentium II. Their chosen benchmark: how long it takes to run a Photoshop plugin. On Mac OS pre-X, a Photoshop plugin got 100%…

Yeah, it is doing a lot of work, as it should be. It's a summary in marketing material, not a research report.

My 4-year old Dell XPS 15 is up for replacement, but somehow no manufacturer aside from Apple is making laptop with decent specs nowadays? I want 2TB storage, a 4k (or close) HiDPI display, good build quality, and not a bulky gaming laptop. The XPS 15 was perfect, it had those specs, except it only had 1TB storage which is now full. I was expecting that to not be an issue 4 years later ... But now Dell discontinued X…

Gaming laptops aren't neccessarily bulky, my Razer Blade 14 is about the same dimensions as my macbook pro 14. They're about the same age and price (2022), the main difference is that the Razer is much faster (plugged in) but the MacBook is vastly more efficient. I do respect how fast MacBooks feel subjectively, but in terms of number crunching and graphics processing the Razer is a lot better. I guess my overall point being youre not going to beat a macbook on efficiency, but there are options out there that aren't bulky or tacky.

Surface Laptop 7? While they don't technically sell a 2TB config, they do use a 2230 M.2 SSD and there are 2TB versions of those. As a bonus it's WAY cheaper to do it that way than from the factory. The Surface Pro tablets are another option if you can live with the form factor. Even easier to swap the SSD in those too.

I'm very disappointed with my Surface Pro tablet ... battery life sucks, resuming from sleep is really slow and the keycover needs to be disconnected and reconnected for it to 'remember' it is there. I've owned 4 Surfaces over the years and won't buy again.

I'm not a fan of OS X but seriously considering one of these just for the battery life and it-just-works portable computing.

Is the performance gap so huge? Power efficiency yes, absolutely, but for peak performance last I saw the last AMD vs M3 benchmarks were a slightly slower single core, and a little faster in multicore. Doesn't seem as world changing as described.

I ran some bioinformatics pipelines on an AMD pangolin notebook. Its was faster than the apple M2 (I think it was an M2 or M3) notebook my work neighbor had. My machine had more RAM, but still for workloads that use the extra cores it made a difference.

The performance alone says nothing. What about the battery life, size, weight, temperature, fan noise, and quality of the touchpad? These are important trade offs in any laptop.

The main problem with the Framework 13 at this point is underwhelming battery life. I have one of the newly announced models reserved in hopes that the new CPU improves that to a reasonable degree, but if reviews come out and that turns out to not be the case there’s a substantial chance I’ll cancel.

It’s annoying that Asus is shipping 14” laptops with 75Wh batteries while the Framework 13 maxes out at 61Wh and doesn’t use LPDDR. On the other hand, it’s annoying ASUS doesn’t ship models with more ram.

Correct me if I’m wrong, but doesn’t LPDDR require soldered RAM (or a CAMM module)?

It's not a Veblen good.

> It's not a Veblen good. What do you think it is then?

This is an incredibly lazy comment. I think you and most people would agree on the immense utility of Apple products. There’s also no evidence that demand increases with price in MacBooks.

I have the same question. My only answer is that making a sleek product such as the Mac Air really is a lot harder than it seems, even in 2025.

> Why is the gap so large?

Good question and probably worth an article or two. My thinking is that Apple is designing silicon that makes for great laptops (M4 in this case) and then building around that. You will be hard pressed to find an x86-64 chipset that does what the Apple chipset does, and without that no matter what laptop you build around it is not going to be competitive. Nimbler companies like Framework are working with more speculative silicon (like the AMD Ryzen AI Max) which people like Dell and Lenovo won't do (yet?) But even there you get closer but not really close to something like the compute complex in the Macbook Air.
