However, if you needed massive amounts of data transfer + multithreaded IOT, this would do the job.
I will say, the more research I do, the less the Rasp Pi matters, SOC/SOM are comparable in prices.
The only issue I have with the Rpi is the microSD lifespan. Of course you can make it read only, but at that point I would pay $10 more to have at least 1GB or less of quality flash memory on it. I've heard microSD will always die at some point. Of course you can also boot from USB too. I'm also waiting for a new rpi zero.
Huh, the new cores are Spectre vulnerable for the first time for RPi.
ah, because of the out of order instruction processing with the SMP. Not thought about that, but the speed bumps all round will more than absorb any OS mitigation overhead.
> 4K! I'm very excited about these upgrades too (especially GigE), but as far as I can tell nothing on this news page specifies whether the Pi will also support HDR output as part of the 4K upgrade. That's most of the practical benefit of 4K - that 4K releases tend to come with HDR10 or DolbyVision support. Anyone know if we can expect HDR output to work? If I knew it supported that I'd be purchasing one right now to…
Can't wait to buy this, boot it up, play with it for four hours, then stick it in the same desk drawer with the other Pis I have bought over the years. (The upgrades look great, just my attention span is not so great)

That's silly. RasPis are stupidly useful. I've got: * A Zero W hooked up to a PM2.5 to do air quality monitoring in the house. Just bought a couple more sensors for it (VOC, eCO2, etc), but haven't hooked them up yet. * A 3B+ running the UniFi controller for my home network. * One is running a custom Hue automation I built to shift the color temperature of the lights throughout the day. * One is built into an interne…
Which CO2 sensor did you go with and how happy are you with it, if you don't mind talking about it?
I'm super excited as well. I figured out the secret sauce to get a low latency kernel build I was able to get down to 20ms latency but I'm excited to see if this can't get down to 10ms even though 20ms is acceptable low audio latency, already with only 1 gig of ram on a pi3 ardour is usable for multitrack recording, excited to see how this does with 4 gigs.
I recently connected a midi keyboard to our Pi3 and ran Timidity for synthesis. It worked, but unfortunately the notes happen about half a second after you press a key, making it rather useless. Strange, since if you dump the midi events themselves to the console they appear to happen immediately. I tried teaking alsa and pulseaudio settings, no luck. Also installed jack but never got sound from it. Eight hours on th…
I had some difficulty with Jack, but Alsa worked great. The main thing is you can't run Alsa and Jack at the same time. Once I was no longer using Pulseaudio, a lot of my problems went away -- I think it's just a really slow interface.
I mostly worked off of http://www.tedfelix.com/linux/linux-midi.html

Clock for clock, A72 is 2-4x faster than A53. But yeah, perhaps it's better to have a lot of small cores for a cluster.
That's great, but if you need crypto (because you have LUKS storage and send AES encrypted data over the network, like in a usual NAS case), A53 with aes instructions may be faster than this A72 without one. And so far it seems these cores don't have aes instructions.
In fact, being slow can be considered a feature in this scenario.

* A 3B+ running the UniFi controller for my home network. What's the unifi controller?

People have spent however many years since the release of the last pi suggesting improvements. It's announced today offering basically everything that people were asking for, and you are already planning for the next one?
Huh? I'm not allowed to hope for future improvements? I'm very happy for RPi4 SD improvements. Until now, RPi has had same lacking ~20 MB/s SD performance from the start. AFAIK, this is the first time ever there's been any hardware improvement in this regard. I've had a microsdxc card with 90 MB/s reads and 80 MB/s writes since early 2014. Some current cards can read & write more than 250 MB/s, so there's still room…
Of course you can. My tongue was very much in cheek :)
...but still, it was announced today, savour the moment :P
