Raspberry Pi 4 goes 8GB, plus new 64bit OS

Quoting: Guest

Quoting: legluondunetI have a raspberry pi 3b+ 2Go and a raspberry pi 4 4Go, the differences I saw:

Oh ! I don't have a RPi so i read and learn. But in another life long ago, i used to play PS1 games in EPSX on a pentium 4 @ 2,6Ghz and a GForce 5200.

I can only assume Leguondenet's experiences are not the norm, as PS1 emulation has been pretty solid even on the very weak Raspberry Pi 2, which was released 5 years ago. The Pi 4 is many times more powerful, so I would hope by now it's more powerful than a Pentium 4, while requiring a fraction of the electricity.

Quoting: DragunovI was just a little disappointed with the Raspberry Pi 4 missing USB Boot support and the USB-C power supply issue.
I won't be buying another RPI until USB Boot is working from the factory.

Raspberry Foundation provides for some days a beta firmware for Pi 4 that enables RPi4 to boot directly from an USB drive:

When I say from the factory, I mean a Raspberry Pi with Firmware from the Factory that allows USB boot. On the Raspberry PI 3 B+ it just worked out of the box, without messing with the firmware.

I didn't nuanced enough my last comment:
for a PS1 you can use a RPi3 (and even 2 after watching your youtube video). But if you want play PS1 with good speed and graphic quality prefer a Rpi4.
For N64, you can play just some games that don't need a lot of power but in fact don't hope to play N64 games in good conditions on a Rpi3.

Emulators version that worked on a pentium III was compatible with far less games and did not displaying games on a HD screen, was not compatible with all gamepads, with some freeze or not enough speed...I don't call that a good playing experience.

Quoting: legluondunet- 4 Go is necessary if you wish to use a Linux distribution with a graphic environment. With 2Go, you can launch one ou two Windows maximum and the desktop experience is not very fast.

Can't say I've noticed that. I've been running a desktop on a basic Pi4 for about six weeks without issues. Mind you, I don't tend to have many things open at once. But Chromium and Firefox aren't exactly known for being light on memory, and I can run them simultaneously (with only one tab open in each, to be fair; I haven't tried any more).

Quoting: DragunovI hope they make a Raspberry Pi 4 B+ with a 1.8ghz+ clock speed, 8gb Ram, USB Boot from the Factory, and get Hardware Acceleration 100% working. Then it will be a really great desktop PC.

Speaking from experience the RPI 4s can overclock to 2.0Ghz rather easily (provided you have the cooling capacity) though that does require editing a configuration file. I imagine once the USB boot firmware comes out of beta it'll be installed from the factory.



I use my RPI4 4GB as the ARM worker node in my mixed-architecture kubernetes cluster but would've gotten the 8GB model if it was available at launch.

• AMD Epyc 7252 (8C16T) + 64GB DDR4 (tainted master)
• AMD Ryzen Embedded R1505G (2C4T) + 16GB DDR4 - Snagged this DFI board for $100 on eBay (Retails for 300+)
• RPI4 (4C) 4GB

The only node without an SSD is the PI as I'm waiting for a cheaper NVMe Hat solution and/or the USB-boot firmware to mature.

Quoting: Mar2ckFinally! We've been bottlenecked by a 32-bit os for too long. I just hope theyre making good progress on that vulkan driver.

They mentioned in a commentary while launching the Pi4 8GB that the progress is going well and that we should hear more news in the upcoming months

What? It does not exist a Pi3 with 2GB. Old Raspberrys had a limit of 1GB

In my experience, the Raspberry Pi 2 and up work well for PS1 emulation as long as you use the right emulator (PCSX ReArmed), and you are not using all the memory for other stuff at the same time.

On the Raspberry Pi models I'm familiar with, the 3.5 mm audio output is pretty bad. A USB DAC can do better; audio through the HDMI* is very good, as is audio through a good HAT.

Also, a Raspberry Pi 2 or higher will handle 1080p video well as long as the player is dedicated and optimized correctly and the network is not choking the stream, but not inside a browser.**

*(For example: Playing music through Kodi, routed through the TV via either S/PDIF or ARC to a stereo/surround setup; surround output is lossy (though high quality lossy), but stereo output is not.)

**(Again, I can enjoy 1080p Blu-Ray rips streaming from my server over a 2.4 GHz N wireless or better network connection with 5.1 channel surround sound through Kodi running on a Raspberry Pi 2 or newer.)

Yep. What I can't understand is why it still struggles with the ZX Spectrum, at least using the build of FUSE in the Raspbian Raspberry Pi OS repos. I'm pretty sure there's a homebrew Spectrum emulator for the PS1. There's no way a modern ARM device should have trouble with such a bare-bones Z80 machine.

I haven't tried emulating the ZX Spectrum on a Rapberry Pi. If FUSE doesn't work well, I would speculate that it's really not optimized for the hardware at all and is depending on it just being such an easy system to emulate. There is also ZEsarUX for the Pi and even ZXBaremulator if you want to try running an emulator directly on the hardware (with no Linux in between), but I haven't tried them.

Quoting: GuestSo you could now run full performance 64-bit windows on this thing or what?

I mean I'll take 64-bit linux any day of course, but windows would make for some interesting gaming benchmarks :D

Problem is that you'd need to compile and optimize the games for ARM. So it might be feasible for some FOSS games, but it's unlikely to happen for any proprietary game (those are all x86).

Nonetheless an interesting idea :)

Yes, I came to much the same conclusion. I usually use ZEsarUX elsewhere, but it's not in the RPiOS repos (at least, not last time I checked).

That's correct; it's not in the repositories. However, there is a binary of the latest stable version for the Raspberry Pi on the ZEsarUX GitHub site in the download section (the latest beta doesn't have a Raspberry Pi build; of course you could build it yourself if you are familiar with compiling software). It's just a zip, but I think it can just be unzipped and run from the resulting directory. I haven't downloaded it and tried it, though. There's probably a README with more information in the archive.

I thought about building it, because it's not something I'm unfamiliar with after 15 years on Linux but honestly, once you install all the build dependencies... it's not that important to me. But the binary sounds interesting. I'll give it a try sometime. Thanks for the info. :)
