@Darksavior How many edits are you going to do lol.

@themazingness You can overclock any pi4 to around 2Ghz right now so there's no reason to wonder.

The Pi 4 actually can go up to 2.147GHz but for stocks speeds of this especially for most emulation out there you wouldn't really need to overclock it because for a couple of my family members that wanted a retro arcade gaming machine mainly for fighting and beat em ups they would all run fine at 1.75GHz so i would assume 500MHz more as a default clock speed would run everything fine but still just wonder if RetroPie would be you know stable because the Pi 400 does remind me of the Pi 3B+ in a way.

@Ecks Why wouldn't it be stable ? The Pi 400 is indeed like a 3B+, it's a higher clocked CPU due to a new revision of the BCM2711 chip on the Pi4. It also has a different board design, which removed the audio/composite jack and 1 USB port, but otherwise is similar with to the Pi4 B.

Which brings us to Raspberry Pi 400: it’s a faster, cooler 4GB Raspberry Pi 4, integrated into a compact keyboard.
It's clocked at 1.8 GHz out of the box, while the Pi 4 model B is clocked at 1.5 GHz.
In the end, it's not a massive difference, but it is a noticeable speed bump for many operations, and can even help make IO faster, for example if copying large files over the network to a fast USB 3.0 drive.

ok thanks and what did you think about my idea as well for integrating the Pi 400 inside of a arcade bartop unit you know like having a slide out drawer under the sticks or on the side of the unit for things like debugging when needed?

@Ecks Sure, why not ?

It looks interesting. I wonder If we'll se a "Pi4B+" down the road with the same SoC and clock speed? I'm curious as to why they did not go with the PCI-E connection (and no USB 3) of the Pi4 compute. Having access to only one USB2 port may have been perceived to be too limited and the PCI-E too cutting edge (for the Pi) for such a device. I also wonder if we will see an 8GB variant or alternate case colours?

it's too bad they didn't include the 3.5mm audio/composite jack for those of us still using CRTs for emulation. or even tv-out pads on the pcb (like the pi zero) would have been nice.

i wonder if it would be feasible to add an A/V jack somehow, or would it make more sense to just use some kind of GPIO hat for composite video output?

either way, looking forward to ordering the kit when they become available again, it's a really cute design and collector's item.

I was thinking about using one of my cabin msx's to put a rpi in it with just msx 1 and 2 games, but this is a much better solution.
I wanted to reroute the original keyboard and that kind of stuff, which still makes an awesome experiment to learn new stuff about writing drivers.

I have a PI4 4gb. Does the faster CPU of Pi 400 will make any noticeable difference against N64 , PSP games?

I ask in case someone bought it and test it, thanks.

The CPU of the Pi400 is just has a higher default clock. You can just increase the clock speed of your Pi4 to 1.8ghz to test if you want. The only thing to note is that the Pi400 has a very large heatsink on it.

[George Spiggott]

@dagna It seem that it is possible to squeeze a little extra juice out of it, it will run at 2.2Ghz. I have not seen anyone overclock their Pi4 past 2.147Ghz.

I have heard that the Pi4's A72 has a theoretical limit of 2.5Ghz so it may be possible to push both of them further if the firmware is modified to do so.

[Ecks]

Technically the Pi 400 is a Pi 4B+ in a sense with the higher default clock and slightly higher overclock capabilities but the one thing i tend to wonder is there going to be companies that would also make a special keyboard case with better cooling solution because i can only imagine clocking it at 2.2GHz would make it quite hot inside of the keyboard and would like to see something of a more passive/stronger cooling for it.

You'll find A LOT of uses for a keyboard once you get into it. I use a Bluetooth keyboard all the time.
