Raspberry pi 4 place your bets here!

Yup, super secret to the point that the project has been featured in the foundation's own magazine a few times.

@deltax5 Again 3Ghz. That would be a twelve core each core running 2.0 Ghz to even get close to a 3Ghz 8086 CPU. That would be a HOT item indeed! Although they have found ways to make them run cool at faster speeds..but this is a new technique and not cheap to do..that would make the pi the price of a modern smart phone ($500-$1,000). I'm NOT taking out a line of credit for a pi! 0.0 Of course I say that now... lol

And the Orange Pi has class/price tiers but no support (or little) so is it useful or not? And yes I am temped to get the Orange Pi equivalent of the pi3 but..I would be "on my own" I think.

Funny how the Arm RISCs were popular in the 80's..then people said they are rubbish..now every body has one (and doesn't know it! lol) ..but then again I know a guy that HATES linux and REFUSES to use it..but he has an Android phone and loves MY pi sooo... shrugs ...but that is a different rabbit hole for a different forum...

Please be enough to run hi gan. I am tired of this input lag.

Snes9x already performs optimally in this regard. It adds no additional latency over what’s already in the games themselves. The only reason you’d want to use Higan is if Snes9x accuracy doesn’t cut it.

On my pc i notice alot less input delay with hi gan then snes9x. even zsnes has less input delay (thou still noticeable). I don't understand why zsnes isn't in retropi it has a linux version. IDK I tested this on my windows pc and I get the same input lag with the pi and windows with snes9x. Sigh I know having a better tv will help cause there is alot that a emulator does causing the lag.

I'd like:

1. the wifi chip to support mesh protocol
   Reasons:

• Rpi 3 native chip supports "ad hoc" but not "mesh".
• Mesh protocol is more lightweight and simpler to implement .
• Mesh is easier to configure (almost nothing to do)

2. An SATA connector
   Reason:

• differentiating permanent connected disks from removable ones
• faster

3. Untuggle RJ45 and USB connectors
   Reason:
   - free network performance

4. USB 3.0
   Reason :
   - Accelerate I/O

5. 2 GB RAM or more
   Reason :
   - Faster
   - Helps distributed Filesystem and DB implementation
   - Helps massive parallel implementation
   - Simplifies big data analysis
   - should fluidify graphics

6. Faster CPU/GPU
   - Something like 2GHz for CPU
   - Upgrade GPU but keeping the API (backwords compatible)

7. same price

8. optionnaly add a GSM card slot

9. use the sound output jack for sound input too or add a sound input jack.

10. Wifi a/b/g/ac

Here is my bet on what I consider realistic specs for a Pi4.

Same form factor as Pi3 model B
1.6 GHz Quad-core ARMv8
New and more powerful GPU
2 GB RAM
USB 3.0 x 4 Port
Built in Bluetooth and WiFi
Gigabit Ethernet
Same GPIO array as previous models (obviously)

We'll have to wait for at least a year from now, so I assume that hardware will be seriously upgraded.

I expect something at the class of a good $100 android phone, with 2-3GB of RAM and an 8-core CPU.

I really hope that there won't be any memory built-in as this would decrease the lifespan of the Pi4.

Also a little hardware power/shut down button would be an addition I would totally welcome.

For those who expect decent N64 emulation, I will have to disappoint you. N64 emulation is far from perfect even on modern PCs. It's a complex software implementation, not that much of a hardware demand.

[drake999]

@matchaman I really hope they focus on upgrading the individual ARM cores, rather than just adding more of them, as emulators on RetroPie seem to be all single-threaded, so faster cores and a better GPU will be the most benefit. Agreed on not having built in storage. I'd rather stick with SD cards.

Well I'm really glad you said it. I think people imagine that a Pi4 with unimaginable grunt will somehow be able to run N64 flawlessly. This is just not going to be the case. I'm running both a desktop and an Android box with much more power than a Pi3, and while you might at some basic level see some improvement here and there, overall N64 runs pretty roughly whatever your hardware. To be honest, it's a minor miracle we have it running at all on anything. It was a notoriously difficult beast the N64, much like the Saturn.

Personally I'm in no rush for a Pi4. The Pi3 does everything I've asked of it and serves the need well. I much prefer it to my Android box as a home centre. In fact I'm getting to the point where I'm done with Android altogether.

Well yes. Granted you can have BETTER performance on a PC, but that is as far as it goes. The more complex system (.i.e. more than one Z80 cpu) makes it difficult. I am surprised the 3DO works at all on a modern PC. (And it does work better with a different emulator I use than the 4DO core. Beyond that anything over 32-bits sans the Sega Saturn is the line. Too complex..too much hardware to emulate let alone loading the software.

More (and faster) RAM would be nice but unless they can start programing the emulators to dedicate a core to a single CPU (i.e. the 3DO had three main CPUs the the pi is a four core CPU..get the idea?) but if that worked so well mame should scream when using more than one core..but it doesn't.

All in all The pi does MUCH more than what anyone thought it would ever do. If the raspberry PI 4 does it better..fine..does it faster..fine. Even if it doesn't I can't complain. :D has a truck deliver the raspberry pi team a few cases of beers

I just want to be able to use "crappy" CRT shaders and not lose performance..my CRT WILL die one day sigh

[matchaman]

After messing with a fantastic new-old-stock CRT TV, it appears that my #1 request for the next Pi would be something like this:

[Rion]

@matchaman No thanks. Better solutions out there already.

RetroTINK
Pi2Scart

[matchaman]

I know but those are external devices. I'd rather have a single unit that gives out the best possible 240p signal.

Aside from specs, one thing I hope they do is change the layout of the ports a bit. I'd like to see 2 USB ports on the same side as the HDMI and power outputs and 2 ports on the opposite side (rather than perpendicular to them).

Some improvement to powering on/off would also be welcome. It doesn't have to be a real switch/button, just a pair of pins that would power the system on and off (with proper shutdown if turning it off) if you short it. Then you'd only need a simple switch, rather than something more complicated like the Mausberry circuit.

I bought a case on Amazon that included a USB power lead with an inbuilt rocker switch (like a desktop lamp), works great. Case, heat sinks and lead for £10

[Beldar]

What I hope for personally is for the Pi 4 to keep a form factor so similar that it will still fit in all the Pi 3 cases. I also hope that it remains below $40 USD. The real charm of the Pi for emulation is the fact that we are all working from the same point of view. What works on my Pi is very likely to work on yours, etc.

It would be nice to see more RAM, a faster chip, slight faster integrated GPU, etc. In other words, incremental upgrades. Right now it does pretty much what I want it too. A little bit of extra juice might improve N64 performance and let me run the high resolution mode for PS1 without a fan. That would be perfection.

Other things like USB 3 and better wireless on board would be nice, but only if the price can be maintained. Honestly, for our purposes do those things really improve usage that much?

Well.. a Bluetooth module that doesn't overheat would be nice too.
