Did you read the blog post? :) "Raspberry Pi 5 consumes significantly less power, and runs significantly cooler, than Raspberry Pi 4 when running an identical workload. However, the much higher performance ceiling means that for the most intensive workloads, and in particular for pathological “power virus” workloads, peak power consumption increases to around 12W, versus 8W for Raspberry Pi 4."

Is there a way to limit the processor power so that it never exceeds a certain threshold? Because some people might be okay with slower processor if it means less power usage.

Yes, there is a low power mode. And you're forced to use that if you startup with an "under"-powered supply.

Jeff Geerling on YT has a great in-depth review of these options in his latest video.

I'm happy that they're upgrading the pi, but it's not exactly lightweight computing in terms of power (they recommend a 27W PSU) or performance/watt (see: your cell phone) To me the charm of the raspi ecosystem was always in giving you a very low power, "always on, almost no power draw" linux environment. Oh well, I guess there's always the older versions or the zero for that.

yeah, i miss the 5-10W early days

You can still buy older models of Raspberry Pi if you don’t need the performance of the new ones.

What do you mean with vague information? There is an entire blog post describing the product: https://www.raspberrypi.com/news/introducing-raspberry-pi-5/

This is pretty bad: "Does Raspberry Pi 5 need active cooling? "Raspberry Pi 5 is faster and more powerful than prior-generation Raspberry Pis, and like most general-purpose computers, it will perform best with active cooling. The Raspberry Pi Case for Raspberry Pi 5, with its integrated fan, is one way to provide this." They pose a question themselves, and don't even answer it. Of course something will perform best w…

Surprised by the amount of negativity here. So many comments that are saying the raspberry pi isn't competitive in their market anymore and then post more locked down less open systems at 2x the price.

Same as the people on Reddit claiming that Raspberry Pi has killed itself as a business because it's constantly in such high demand that it's always sold out.

They're claiming that they've killed themselves as a business hobbyists, which isn't exactly wrong. During their supply chain issues they made it clear they were prioritizing their commercial customers over the hobbyist market.

At this point the hobbyist community has moved on to other things (shout out to odroids). I don't think raspberry pi is going anywhere, but they do have a very different market and customer base than they did five years ago.

Also as a company their social media people really are assholes, which doesn't help at all.

I mean, keep in mind that the Pi5 is a $60 device with ~$60+ of support hardware (Power supply, cable, miniHDMI to HDMI, Cooling, Case, Storage) You can get considerably more powerful mini PCs for less than a 4GB Pi5 with needed accessories that is upgradable, has further software support, and includes all of what you need to get with a Pi. Also, you are reducing eWaste.

Name three, please, with emphasis on the "considerably more powerful" part.

Given outliers in a skewed dataset, wouldn't median be a worse description than mean without outliers? https://openstax.org/books/statistics/pages/2-6-skewness-and...

I think the median works better in this situation because the huge population means that both the outliers and the skewness have much less effect than they do on the mean. The problem with using the mean “without outliers” is that you have to make arbitrary decisions about what data to exclude as an outlier, unlike with the median.

Please stop using “average” for wage comparisons. It’s an utterly useless metric for showing if wages are moving or not. If you must use average, then you should remove the top 5% from the average.

> If you must use average, then you should remove the top 5% from the average. 5% is too arbitrary, just use the median.

5% is not arbitrary. It is removing massively skewing outliers who also see a massive growth outlier compared to everyone else.

Looking at wage movement as slices of where one falls gives a clearer picture.

Additionally, the reason it doesn’t make sense to remove low wage outliers while removing high wage outliers for average is because the median wage is closer to low wage outliers than it is to high wage outliers.

For example, if you take the median and then +- for your dataset (if median is 48,000, then use 0 thru 96,000), you’ll be removing more than just the top 5%, and yet, this also gives a far far far better picture of the dire economic position and what is happening with real wage movement.

I'd like to see an RPi that includes an Arduino (or maybe an ESP32) on board, with some way to easily connect things to that Arduino's GPIO pins, and with the Arduino programmable and controllable from the RPi. This would let you run things that need real time GPIO access and real time interrupt handlings on the Arduino, and would also give you DAC and ADC.

The RP1 has two Cortex M3 cores and a PIO core, and is responsible for the GPIO pins. So I think it already has something close to what you want.

I want a dirt-cheap Zero (if possible one that does not need an SD card), not something that tries unsuccesfully displace a NUC :(

What suggestions do you have for this?

I’m sure some people can find these, but every time I see comments like these (or ones that actually give specifics), it’s always used ones on eBay that aren’t actually better and are in unknown condition.

I’m not doubting that some people come out ahead, but for me, being able to get* the same hardware each time, new, has value. Also, a huge draw for RPIs for me are the GPIO pins.

* Yes, the past few years were hard, but not impossible.
