----------------------------------------This looks significantly more powerful than even the 3B+.
Important note: I don't believe WCG currently supports any applications on Linux for ARM, only Linux for amd64, so this would need Android installed -- if that is even possible on a Pi -- in order to participate in WCG projects. Other than that caveat, I'm really excited for this. Considerably faster CPU, LPDDR4 RAM (and up to 4 GB!), finally full GigE, beefed up Wi-Fi and Bluetooth, USB 3.0 finally, 4Kp60 HEVC hardware decode, USB-C power supply with more current, and finally a die shrink from 40nm to 28nm. The blog post says they are considering introducing a compute version of the Raspberry Pi 4, whereas this one is the general purpose one.

This is excellent news.
----------------------------------------For WCG indeed we need Android for the RP4. I use a RP3 with Android but the installation process (I've did this 2 years ago) was cumbersome. It will be interesting to know the electricity consumption at 100% and if active cooling is needed.  |

It will be interesting to know the electricity consumption at 100% and if active cooling is needed. According to the Tom's Hardware review The electricity consumption is slightly higher than the 3B and if you run it at 100% it will thermally throttle itself, so a heat sink, either active or passive will be a necessity.

I will try to buy it once it comes out. Hopefully in the future WCG would be able to support the native Raspberry OS that comes standard with it. So far I have 4 of them crunching for SETI and Universe@home and they have provided a lot of value so far.

I'd like to buy a stack of Pis or Odroid N2s and put them in a rack or "windtunnel" with a 120 mm exhaust fan at the top.

Eventually I'd expect that a version of Android will appear that suits it. I'd wait until that happens before purchasing.
The RP4 should be cheaper than an Odroid N2 but we'll have to see how the speed ultimately compares. |

I'd like to buy a stack of Pis or Odroid N2s and put them in a rack or "windtunnel" with a 120 mm exhaust fan at the top. I have 14 RPi 3B's and am continually amazed at the large amount of work they do at Universe while using almost no power and producing very little heat. They are maintenance free and so reliable I only check on them about once a month. I stack them in two clusters using these: https://www.amazon.com/gp/product/B07K72STFB/...o00_s00?ie=UTF8&psc=1 and keep them cool with only 1 small external fan. https://www.amazon.com/gp/product/B012BKZC86/...n_title?ie=UTF8&psc=1 Stacking them reduces the footprint and also makes cable management MUCH easier and neater.   |

I wonder if android will work on the RPi 4. That way I can get a bunch of these little guys and have them crunch Zika and SCC. |

There are several versions of Android available for Raspberry Pi 3's. If the hardware is close they may work on 4's. I've been using LineageOS on my 3B's.
There is also the ability to put Windows 10 for arm on RPi 3B. I've got one set up and running Boinc. It's VERRRRY slow, as in click somewhere and 20 seconds later it notices. Both will run World Community Grid projects. The Windows 10 one reports as an x86 processor. It takes about 30 hours to run a MIP unit. It got 3 SCC betas and they took 12-18 hours to run. you will need to put heat sinks on them and use a fan. |

I did not know this. Thanks smeyer55! |
