Are those results available anywhere else?

My thought as well. I can only see one tweet, no replies. I'm guessing it's a thread, and you need to have an account to read the replies?

Replace x.com or twitter.com with nitter.net ie.

Five generations in and it finally gets radical features such as: - a power button - a real time clock Crazy it took this long but finally, seriously. Downsides here are that it might need more active cooling whereas previous generations worked without it. Also, ugh: > Gigabit Ethernet, with PoE+ support (requires separate PoE+ HAT)

I've gone to unholy ends to syncronize large herds of Pis using a patched NTP server and several other dirty tricks. The RTC is a huge deal to the people who care about it.

Do you mind delving deeper into this RTC for those who don’t care about it (yet?).

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.

At 27W that is a strong pass vs a NUC. If I go with a low power x86 NUC, I can run all software on it, and probably insert a SSD + additional RAM, for probably ~15W.

It's 12W, not 27.

There's always RISC-V.

Curious how Milk-V Mars CM [1] holds up to an eventual CM5 [1] https://milkv.io/mars-cm

A bit slower than a CM4, of course.

The Lichee Module 4A is a CM-style board, though not compatible with CM4, and is generally a bit faster than a Pi 4.

That's the fastest RISC-V you can get right now (but you can get 64 of those > Pi4 cores in one chip!). Chip and boards in RK3588 class coming next year, so that's ~Pi5.

I wonder if anyone here is using RPi as a main PC? Seems to be capable of most office work with a bit of multimedia on the side. My laptop is dying and I would love to get something stationary that is low-power by default yet good enough so that the internet wouldn't lag. Mounted at the back of an LCD screen could make a nice wireless setup with the other peripherals.

Unfortunately, it is too slow to even smoothly power a desktop environment.

It's ARM with quad A76 cores. I was curious up until this announcement to see if they'd ever release a RISCV raspberry pi.

I asked Eben about that in an interview earlier this year, and the answer is "probably not too soon" — RISC-V has a lot of designs available, but most have been in the lower-end 'efficiency' class compared to cores like A76 (which the Pi 5 uses) and Neoverse, which are a lot faster. But tech progresses on... never say never.

A76-class RISC-V cores have been available to license since June 2021, and boards with them will be arriving in H1 next year.

Amazing benchmark results https://www.phoronix.com/review/raspberry-pi-5-benchmarks

I was going to post to ask how it was likely to compare with the current crop of RK3588 boards that are marching towards decent mainline support, but this link already answers this to some extent. It looks like it's faster on some benchmarks, slower on others, but basically in a similar ballpark?

Yeah, and these results are achieved on 4 cores instead of 7.

I really wish they would have just built in PoE+ rather than requiring a hat; the hat dramatically reduces the choice of case hardware. Now I want to see what they do with the RPi Zero.

RPi zero2 just came out (I know, but you haven't been able to buy it until the summer of 2023).

Though it is a massive improvement over the Zero.

Thanks. This is a bit surprising to me since they advertise two 60 Hz 4K display drivers...
