Just to correct your (and to be fair, other commenters misconceptions), while the 7020s do re-use Zen2 cpu core designs, they are built on a revised 6nm process (upgraded but compatible with the olde 7nm process that Zen2 Ryzen 3000 debuted on), they use LPDDR5 (not DDR4), and they use new RDNA2 gpu cores.
This has practical implications also. Zen2 is for example vulnerable to the Retbleed attack, and properly mitigating it has serious performance impact. If Google decides to partially mitigate, it will be interesting to see if someone manages to hack into a Mendocino Chromebook at the next pwn2own contest.
Another drawback is that RDNA2 lacks hardware AV1 encode support, so using these Chromebooks for video conferencing will become an issue once the major videoconferencing solutions switch over to AV1.

It sounds like you are not in the market for an APU this small, but it at least looks to be quite competitive on paper with newer low power offerings from Intel. And if the Steam Deck is anything to go by, they'll be incredible efficient in the sub 15 watt category.
Slightly off topic:
The 7940HS would make an awesome mini pc (FP7r2 version to allow for easy RAM expansion). If there was something smaller than 15W it would compete well with network devices like https://www.servethehome.com/inexpen...-i225-pfsense/ but the embedded market seems to be last on AMD's list. Not that I blame them, it's a tough market to compete in but I would like to use more of their products. My firewall uses an Intel Atom from 2013!
I've been very vocal about my displeasure with AMD's new naming scheme that buries the core design generation in the third digit, but at least these new chips are indeed something new.

It's crazy how people expect randomly assigned model's of CPU don't fit their bill of material expectation.
Move along?
Joe Blow isn't going to understand ANY of this; he's being talked at by a honigwurst und krawatte trying to get commission.
'Experts' going to peen.
The rest of us, read.

A few years ago I had to use a dual-core-without-hyperthreading machine, one of those freestanding units where the guts of the system are squeezed behind the monitor, and while it wasn't awful, it wasn't great either. I pity anyone who has to use that now and as the system ages going forward.
As far as a laptop use goes, I think that Athlon 7120C shouldn't exist. I don't think anyone knowledgeble would choose it, but some people will be forced to use it.

You can 'simply' replace the lithium batteries for a few Space Credits in sealed laptops if you get a decent tear-down guide to speed up the dismantling.
Solid laptops deserve that attention.

Correction thanks to nrganger: 7020 series in fact does use LPDRR5 and 6nm fab. The 7030 series is the one that uses DDR4 and 7nm fab.

I got a nice 17inch Chromebook for less than $400 dollars awhile back, only problem is it has 8GB of RAM and a 4 core Jasper Lake processor. It sucks all around, which is a shame because Chromebooks are some of the finest, least buggy, Linux laptops out there. Plus they have a security record that rivals OpenBSD because of how locked down they are. I would gladly pay $600 or $700 for a full featured Chromebook with 32GB of RAM and an 8 or 16 core processor!
Productivity is EXTREMELY important for me on my work daily driver. I am a fan of Apple laptops hardware but I can't stand the OS and besides the efforts Linux still isn't very stable on it in my experience. The next best thing I found was Dell with official Linux support. I payed about $700 USD for my Dell 5495, everything works and the laptop is still spotless after being used every day for more than 5 years. I've got a Ryzen 2500U 4C/8T CPU, 16GB DDR4, 256GB NVMe, 14" 1080p IPS screen. The processor scaling can be set to ~15W and remains 100% stable that with the 65Wh battery works really well*. Build quality is really good. The keyboard decent once you get used to it. I ended up buying another one for my colleague and he's still using it too till today.
* After 5 years of daily use the 68Wh battery is now a 40Wh one. My guess is I've done over 2600 charge cycles which isn't that bad considering total system cost.
I'm looking to upgrade my system, but I can't find a good laptop with excellent Linux support. I refuse to buy a laptop with a monster GPU that just ends up sucking power while idling or causing driver problems. So far it looks like Asus is my best bet (based on availability in South Africa). I have heard some good things about asusctl, but I still need to do more research before making up my mind. I suspect AI cores will be a requirement in the next 5 years, so that pretty much just leaves me with the 7040 series.
A Chromebook with a Zen4+RDNA3 chip, 16 cores and at least 32gb DDR5 would have been legendary! I would pay $2000 USD for that. Since we are talking about utopian product why not through in a solid state fan for dust-proof, low-power, low-to-no noise cooling.Last edited by Jabberwocky; 24 May 2023, 04:52 AM.
