Real curious what the actual ethernet speed on that Raspberry Pi 4 is - hoping for 1Gbit. Anyone know whether the existing PoE HAT will work on it?

article posted:Beside the “true” Gigabit Ethernet port, the good news for people interested in network storage applications is that the shared USB + Ethernet bandwidth is gone, as there’s a separate Gigabit Ethernet transceiver (BCM54213PE), and USB goes through a VIA VL805 PCIe to 4-port USB 3.0 host controller. The latter means BCM2711 comes with a PCIe interface giving the Raspberry Pi foundation some flexibility for future Raspberry Pi SBC’s. So the new chipset has PCIe support like many of the Rock based boards already do, except this one comes with the support of the full rPi ecosystem. I hope they'll make a "Raspberry Pi 4 C" with a 4x PCIe slot to plug things like raid controllers or audio cards into. full datasheet is here: https://www.raspberrypi.org/documentation/hardware/raspberrypi/bcm2711/rpi_DATA_2711_1p0_preliminary.pdf e: iperf benchmark https://twitter.com/ben_nuttall/status/1143037993957187584 e2: Hadlock posted:I hear you on that, but at the same time, the last time there head of raspberry pi swore up and down that they definitely weren't releasing the pi 3 and that the pi 2 b+ was great for now... Less than 60 days later they announced the pi 3 anyways this was correct by the way  eames fucked around with this message at 10:54 on Jun 24, 2019 |

Just because everyone is going a bit gaga: - Micro hdmi instead of 2*miniDP or HDMI + DP altmode on USB-C - local bus is still USB (but 4gbps apparently so not bad) - SoC is still 4? generations behind - armV7 kernel because why? Overall ‘tis still a banger IMO.

evil_bunnY posted:- local bus is still USB (but 4gbps apparently so not bad) that's completely wrong. raspberry pi foundation posted:The Ethernet controller on the main SoC is connected to an external Broadcom PHY over a dedicated RGMII link, providing full throughput. USB is provided via an external VLI controller, connected over a single PCI Express Gen 2 lane, and providing a total of 4Gbps of bandwidth, shared between the four ports. evil_bunnY posted:- SoC is still 4? generations behind and there's no threadripper version available either  evil_bunnY posted:- armV7 kernel because why? backwards compatibility. it'll run AArch64 distros just fine, like the 3B+ already does.

evil_bunnY posted:Thanks for the correction. I don’t see the point of backwards distros anyways since you need the latest rasp release anyway It's mostly about packages. arm64 is still missing a good amount of packages compared to armhf but it's catching up and there's little doubt that it will replace armhf eventually  this is the best readable document on the rPi 4 I've found so far: https://cdn.shopify.com/s/files/1/1560/1473/files/Inside_Raspberry_Pi_4.pdf

I just bought a 3b+ and got it set up as a DietPi media storage.  Ah well. It's sufficient for the task of actually watching the media, and the thing the 4 would noticeably improve upon for the setup would be download and network transfer. EDIT: That being said, I do have a separate project that involves 7-8 Pi Zero Ws running their roots off of NSF. I have one I'm finalizing now using an old, USB 2.0 laptop, and then I'm planning to clone the whole setup 7 times. With the new speeds, would a Pi4 with a USB 3.0 HDD be able to handle the whole system? As far as I understand, all the processing is still being done by the Pi Zeros, and it's just data that's being pushed by the NSF server. Just a matter of figuring out my top network speed on the Zeros and dividing it into the new top speed for the Pi4, right? Alehkhs fucked around with this message at 17:41 on Jun 24, 2019 |

Looks pretty cool to me, especially the 4GB version to replace old desktops. Driving a 4k display, full USB 3.0, etc. is pretty impressive for what's still a small little ARM SOC. I think the biggest weak spot is the software now, Raspbian/Debian is just too old and not with the modern times. It'd be awesome to install Chrome/ChromiumOS and then just have a docker/container engine to run whatever your heart desires. edit: Also another nice thing buried in the specs, the USB C port is wired to a USB 2 channel on the chip. This means the USB C port can be configured with the kernel to act like a USB device, like an ethernet adapter, mass storage device, serial device, etc. The Pi zeros can do this already and folks have some cool things like plugging the Pi into your computer and it showing up as a USB drive to move files to it. It will be pretty nice for a 'real' Pi to work the same way. mod sassinator fucked around with this message at 18:12 on Jun 24, 2019 |

This performance jump should be decent enough for N64 (and most PS1 games) emulation. Wondering if Nintendo had a N64 mini on the works and were waiting on something like this.

Even if so, it's probably too late. They already abandoned the NES and SNES mini, and it's unlikely they will ever release an N64 mini.

The sad thing about the 4 is that it still does not have the crypto extensions. So no accelerated Syncthing.

It's too bad they went with MicroHDMI. That's my least favorite of the myriad of digital video connections. Presumably it's not trivial to do a stacked full-size HDMI.

They also have a USB-C port right there. Having a full-size HDMI built-in and allowing people who want a second display to do so via a dongle off the USB-C port would have been a much better option.

There's a config file you can update to make a one time change that enables USB boot on current Pis. I read that USB3 boot will be an option, but they hadn't implemented it for the test devices they gave reviewers yet.

I'm actually hoping to host a cluster of POE nfs-rootfs Pi Zeros off of a Pi4 NAS, now that speeds sound like they're more up to the task. Pi4: It's coming. raspberrypi.org posted:Support for these additional bootmodes will be added in the future via optional bootloader updates. The current schedule is to release PXE boot first, then USB boot. Alehkhs fucked around with this message at 16:59 on Jun 25, 2019 |

That said, this article indicates that they feel they're using every bit of the PCB area available, so maybe this is just the best we could get while retaining the expected formfactor. https://www.raspberrypi.org/magpi/eben-upton-engineering-raspberry-pi-4/

The 4GB version isn't just a Pi anymore, I'd wager it can replace 90% of folks old lovely Dell desktops that are wheezing and on their last legs.

It's a shame that the GPU appears to be still pretty limited, but at least it's still a massive step forward over the circa 2006 GPU design all previous Pis have been using.

Cojawfee posted:I'm not really even sure why you would want to have two monitors with a Pi. They're apparently working with Citrix to make the idea of a Pi-based thin client a serious option, and a lot of the early messaging for the Pi 4 has pointed out that at least the 4GB model is truly viable as a low-end desktop. A lot of businesses now accept that dual monitors help productivity so being able to support that use is interesting if that direction pans out. It could also allow for some neat new uses we haven't seen Pis used in before. I've seen the DIY Arcade guys talking about using it to drive a marquee display or even dual-screen vs games. I'm interested in it for a CarPC project I'm playing with as well as adding a second screen to my home theater environment. Obviously the commercial signage folks will have a field day with it.

I like working with dual monitors on things. tbqh I have a horrendous short term memory so I usually need things side by side like a document on one side and my work on the other. So in that respect it wouldn't be bad. When I read Micro HDMI my mind instantly thought "crunch!". They are even worse with physical loads than micro USB. I'm not knocking the RPi 4. I think it's a neat feature. But it's not a great connector.
