Could you do a video on how it performs day-by-day tasks, like browsing with 1, 2, or 10 tabs open, watching youtube videos, etc? Using external video recording so we get a true sense.
As long as you choose the 4 or 8Gb version, it will work similar to a 'normal' laptop from about 5 year ago. Especially if you hook it up to an SSD and ditch the moronic SD card.
Not exactly that, but in a similar vein, check out my 'Pi 4 a Day' video: ua-cam.com/video/OU6jHvVqJxY/v-deo.html - it is a good little computer, but has reasonable limitations, mostly having to do with running desktop Linux (versus macOS in my case). A lot of those limitations can be overcome if you give it time, but some (like certain applications just not having a true equivalent, like Final Cut Pro/Premiere, or Photoshop) are a little harder to live with.
I have finally found a place where the answers "to how" and "to why?" matter more than "what for". Every time I watch one of your videos, I feel that you are making a call for people to think for themselves.
Thanks! I'm learning so much from you, between this, your Ansible book and examples, and other stuff you're posting. One of these days I need to dive into k8s...
The best design will be monolitical design with full size pcb and mechanical swiches soldered right into it. No full case, no covers at the bottom, maybe some protective frame around keys, no heat... But price of mechanical switches is big, and large pcb also not cheap.
usually companies that send samples to reviewers, send them before release date. They just assure the videos will be released after a certain date through contracts (NDA's). So I guess the last two review and disassembly videos where filmed and edited around the day he received it and this one was done along the line after having some time to play with the 400.
I wish! And to others saying maybe I pay an editor, nope! I've spliced thousands of hours of DV since the late 90s and know FCP like the back of my hand... though it would be nice to someday have the means to get someone to help with editing. It takes a looot of time. And these videos were kind of a special case. I completed all three (from filming to uploading starting Saturday night (so just over 36 hours for three). That's burnout-level work, so tonight I will sleep, and tomorrow I will probably turn off the UA-cams... at least for a few minutes 😂
Helpful video thanks. on my Pi 400 I've settled for now at over_voltage=8, arm_freq=2200 without also adding force_turbo=1. force-turbo=1 appears to hold the cpu clock at the maximum 2200Mhz all of the time rather than just have it increase on demand. What I am using is working well and visibly faster for me. I did also try arm_freq=2300 and my Pi 400 booted OK but hung 5 minutes into a "stress-ng --matrix 0 -t 30m" stress test. What a joy this tiny inexpensive machine is. Takes me back to my ZX Spectrum days when I was 16.
So, we should expect a "C" revision of the Rpi4 anytime soon with this slightly improved CPU revision. I'm wondering if the upcoming Rpi4 will be able to reach 2.5Ghz-2.6Ghz Overclocking speeds which would be awesome for retro gaming.
The pi4 has a lot of heat issues because of how close some of the componets are to each other, with the pi 400 the mobo is longer from each other . The USB /ethernet controller is one such the wifi/bluetooth is another componet that heats up. This is why pi3 had so many heat sink options but the over all issue is they didn't have any that took affect because they were so small, I had copper ones and they made a small difference. Copper heatsinks made big difference for the system on a chip though.
Every Pi can use a heatsink. From watching the clustering video, I think the Pi 400 board cab benefit from that plus overclocking. But the resulting heat problem would require a heatsink plus a fan, maybe even a watercooling fan. On second thought, the Pi 4 8gb can be overclocked to 2.1 ghz, and it has twice the ram plus Bluetooth. Just a pair of these add up to 16gb ram and 8 cores. Clustering 3 or 4 of them, with overclocking and cooling, could give you all the cores, speed and ram you want.
It seems to me that the easiest way to increase cooling would be to fold the aluminum shield into a bunch of small peaks and valleys. Depending on the number of folds it could dramatically increase the amount of surface area that can be used for cooling.
nice to see you trying this, can you also do some tests stressing the GPU as well, I find that heavy GPU use causes more heat issues than running all the cores?
I made thermal tests for mobile phones and result is: even that thin plastic gave about 20 minutes temperature gradient inside the device before settling while stepping ext temp from -30°C to +60° in one minute (or vise versa).
In the case of this Pi, since it has some gaps in the plastic/metal interface, and the vent holes on the bottom, it seems like the plastic itself doesn't get as hot, as the heat escapes other ways. I've only tested it using stress-ng for about 3 hours straight, and the temps on the top surface were still under 33°C (and it didn't feel warm). The bottom side did get a bit warm to the touch, but nothing that I would consider 'hot'.
My 400 runs at 7V; CPU @ 2150 and GPU @750, been running smoothly for 8 months on the Pi OS, and Ubuntu Mate 22.04 for two weeks, no issues. Not using turbo mode.
Excellent! I wonder whether the heatsink would mess up the keyboard electronics in the long run assuming it's not designed to operate under such thermal conditions.
OK now I actually regret bringing an RPi 4 just 2 months before this. I thought this wouldn't survive an overclock but damn. I guess the results would also be similar if you overclocked the GPU to 750MHz, though I wonder if it can beyond that...?
When comparing power consumption, the most accurate comparison would be watts. We can see that the voltages differ slightly on your tests, so intensity alone is probably not meaningful.
True, I haven't had time to log the data in any way yet, unfortunately. And really for tiny comparisons where the CPU is overclocked slightly, this power meter is probably not the most accurate.
Hi Jeff. Very good video. I want to buy one for my kids online classes. Some UA-cam video watching, document edit. Which would be good in performance Pi 400 or Pi 4 8GB?
Just a question... I did some testing with a raspberry pi 4 and a 3 and measured power consumption as I was quite confused by the numbers on your website... I stressed all cores and both consumed about 6,7W which is... quite far from your result of the Pi 3 on your website... Do you have a theory on what could cause this discrepancy? Maybe a faulty meter?
still running 2.2Ghz ? or now on 2.3Ghz -> 2.4 Ghz range? with the updates? would love a small update on all these old OC test videos... you actually use them right? RIGHT??? :P
Hey Jeff, can you stress the pi 400 without the heatsink installed? I'd like to see if the rev C cpu is cooler than the rev B used in the existing pi..
How exactly does the power button on the keyboard work? Is it a simple on/off button I could hit by accident, or is it a software controlled shut down and wake? Can it be programmed easily enough to make it harder to turn the machine off, like hold control and power for 5 seconds?
It is actually pretty impressive considering the 400 has no fan. Complete passive cooling. What is the ambient temp though? It may hurt at hotter regions...
Yes , pi foundation should have send one to derb8ur .. 😂 he would have used ln2 cooling and external power module and push like 300watts to that poor arm chip and make it reach 5ghz on all cores 😂
So 2GHz is the fastest overclock without risking potential catastrophe it would seem. Sure all the emulators will run nicely considering the price and overall spec.
Wait, at 4:00 the overclock at 2.2GHz improved a lot more overe 2.0GHz than 2GHz did over 1.5 It's really everything equal on the SoC? At 1.5GHz, does it behave the same as a normal Pi4?
I want to see what kind of nas you can make with the Raspberry Pi 4 compute with IO, as it has an exposed PCIE interface. Is it posable to create a tinny nas with two m.2 drives and no other power source but the Raspberry Pi.
I have my 8gb at 2.2 GHz with over-voltage set to 8, but I didn't use force_turbo. Does that mean it's been running at 6 this whole time, or do you even need force_turbo? I've run every stress test out there, and it works great...maybe I got lucky.
Yes! That's actually one of the use cases I think it's perfectly suited for. I didn't have any trouble doing Ansible (a Python app) development work, or website dev work (with PHP, CSS, and Javascript) on the Pi 400 I have.
I copy paste the code for 2.2 but my rasp pi 400 shows more. The first time 2.3 and the second time Ive tried 2.394. Is there anything I should do to fix this?
Is there space to stick a tiny notebook cooler into the case? EDIT: just rewatched the disassembling video. No space. No problem though, with these temps
According to someone in the Pi Forums, even force_turbo doesn't void the warranty on the *Pi 4* at least. Though the documentation says it 'may'... so take that for what it's worth. Just overclocking and overvolting (up to 6) is still fine, though, without voiding the warranty.
So, what is the deal with poor 1080p YT playback on base Pi4? With ARM phones being able to run it effortlessly for years now, why Pi has such problems?
I think it's mainly all the fancy web UI UA-cam layers on top of the video. Videos play back perfectly smooth, but when you move your mouse over it and the overlay fades in and disappears, and when you click the video controls, the browser does a good deal of work painting all that on top of the video. It's something that I think could be optimized better, but on mobile, the apps can use native rendering tools, and on most computers, there's a lot more power on tap than the SoC in the Pi.
@@JeffGeerling makes sense. This would also explain why an old netbook that I had arguable pleasure to use not so long ago this year had such problems with displaying modern websites. Poor AMD-C70. On the other hand it seems like my Pi3B+ struggles to run YT even in a background tab (so, it doesn't have to display anything related to YT), which is a shame, as I'd love to use it as a word-processing workstation from time to time.

The size of the board probably makes a difference too. More copper in the ground plane to spread heat.
