I would like to see the gaming performance with the 2 & 4gb version, while it is more horsepower, is there really any great performance bump?
This was linked above: https://www.raspberrypi.org/magpi/raspberry-pi-4-specs-benchmarks/
Scroll down to the benchmarks section and you can see there is massive improvements in performance compared to the 3 b+!

@dankcushions are you sure pcsx-beetle-hw works? If I'm not wrong it doesn't work on ARM CPUs
-
@Chuck_B obviously i'm not sure about anything, i'm just speculating :) but yeah i think it will need to wait for the ARM dynarec in that instance.

Another comment of interest from the Official RPI Forums:
Buster will release with a 32-bit userland, as backwards compatibility for all previous models is important. The Pi 4 kernel uses LPAE but eventually we'll ship a 64-bit kernel.
That's great news for the near future, specially for arm64 dynarecs such as in
lr-mupen64plus-next.hmm in that particular case i don't think will be useful since there's been a perfectly serviceable 32-bit arm dynarec since forever, and n64 isn't CPU limited (that side of things full speed on a pi2).
As far as I understand, m4xw implemented an aarch64 dynarec for mupen64plus-next that is the one actually used for the Switch (his main target platform). This dynarec is independent of the existing 32bits dynarec.
At some point we were discussing if testing that on an aarch64 RPI3 image such as this or this to see how it goes, but ultimately didn't happen because of all the issues/headaches that non-official images potentially have.
But if the foundation is going to release a well-supported 64 bits Raspbian version, then definitively I would like to see how this dynarec goes there.

Woooow!!! That's awesome. Will it be able to emulate the Nintendo GameCube. Nintendo GameCube in the Raspberry Pi would be incredible!!!

"We’ve explained how to overclock the Raspberry Pi 4 and what kind of results you get in a separate article. However, the top line is that you can easily get the 1.5 GHz CPU up to 1.75 GHz and increase the frequency of the GPU from 500 to 600 MHz without missing a beat. Just make sure that you have active cooling."
So overclocking will be possible on this board as well. Cant wait to push one of these to the limit. :)

not quite, m4xw created the mupen64plus-next libretro core which uses Gillou68310's dynarec (which is his 32-bit ARM dynarec updated to support aarch64, as far as i'm aware).
in any case, there's no improvement possible, essentially. the ARM 32-bit dynarec is accurate (at least, bar a few very specific issues), and doesn't even tax a pi2 (look at CPU usage when running n64 games). that said, it would make sense to move forward to whatever the current flavour of the month is, given then option.

dolphin developers are testing it out, so it's possible, but wait and see :)

Ah that is corerct. Sorry I got confused then. I thought it was a different dynarec for aarch64 and not a ported version of the 32 bits one. My bad. And yes, the CPU is not very taxed during n64 emulation. That's why I actually think the GLES3 support is the bigger news for the n64 emulation front.
Thanks for the clarification!

GameCube on Pi?
Cannot believe that, but in these days everything seems to be possible :D
If so i need a Terrabyte SD-Card, i dont like external drives or Sticks attached to my Pies, i want to keep it compact ;) -
Just another thing i want to mention: is this Upton-Guy cool or what?
It is the same procedure every time, the releases come out of nothing.
"no, we dont have a release Date. We dont even have a concept by now. Maybe next year".
I start to believe he likes to play with us hungry users. :D -
The much higher memory bandwidth together with the boost to GPU speed will should make multi-pass and more complex shaders viable.
crt-pi was always limited by memory bandwidth as much as GPU speed.

@dankcushions said in The new Raspberry Pi 4 is here!!:
this is HUGE news I think. it should mean fullspeed and accurate emulation for:
- n64
- dreamcast
- saturn
i should think the new CPU should allow for full speed current MAME also, but we will see...
This sounds like a game changer! I was expecting a big step up in graphics, but didn't know the GLES think was the key. Finally N64, Dreamcast and especially my biggest complain full MAME!!
What do you think, could this new cpu also help to reduce input latency? I know its not directly tied to latency, but with optimizing settings for this kind of approach. Also using quality shaders wouldn't do too much impact now. I am very excited!

this is HUGE news I think. it should mean fullspeed and accurate emulation for:

and better emulators for

I hope also for Atari Jaguar and Pc-FX

So cool but will mean I have to take a dremel to the MegaPi case :(

PC-FX is possible but Jaguar is very unlikely, the only open source emulator is Virtual Jaguar and it's very incomplete even on PCs.
However there is an emulator for android called "Phoenix" that runs everything perfectly even on 2014 phones but it's closed source.

The additional performance will make it possible to reduce input lag, yes. There’s also one potentially very nice side effect of moving to the new OpenGL driver: The last time I tested this driver, it had one frame less input lag than the default video driver on the Pi 3. This means that there’s the potential of one frame less input lag at default settings for everyone using a Pi 4!
-
I would think 3DO emulation should be in the realm of possibility for the pi 4 as well. Last time I tested lr-4d0 on my 3 b+ it ran at about 35-50fps with multi-threaded DSP. I would think the pi 4 should likely take it to fullspeed.
-
@Brunnis I didn't think of the driver, thats great to read, especially from you. ;-) Looking back to your old input lag investigation thread, I see you had tested the OpenGL driver alonside with the Dispmanx driver, which was always approx. one frame slower. Can we expect that difference still or do you think (speculation) won't be that a difference now, as the OpenGL backend is fixed?
To me personally, that alone would be a good reason to upgrade soon (this year, not now), which is a bigger news to me than the improvements on N64 performance. I expect that we will be able to adjust video_frame_delay, video_threaded and video_max_swapchain_images a bit on all 8-16 bit consoles. I would be happy with that. For the runahead is still not enough room, just my speculation. The only thing missing I really wish it would support is variable refresh rates of monitors.
