@nastybuttler322 Any move forward will be welcomed by me! And in regards to the ultra slim, mine get stupid hot too:((

Just put heat sinks on your Pi like I did in the images, and try the N64 games from that card. The overheating problem shouldn't exist for you after.

I say if they do make a Pi 4, they should make 2 versions.

Basic version: Upgraded cpu/gpu, better performance, $35
Pi 4+: more powerful all around, flash storage, more ram, etc.

Fruitybit

@nastybuttler322 Now that's a clever idea:) won't fit in my case though!!

Fruitybit

@lilbud They'll probably have thousands of 3's left over and would sell them as they have done with the 2's, alongside them. Same with the zeros. It would be nice though.

I still don't get what he meant by 'layers in the chip' I'm going to have to brush up and do a bit of research today.

Like I said in the other post..
(I seem to have lost it)
if they can't fix the heat problem we'll never see a rasp pi 4. And now that the Orange Pi has a "RetroPie" (RetrOrangepi) image of it's own the Raspberry might lose ground quickly.

I want to know if I can get 2GB DDR3 ram and a quad care cpu..maybe even a dedicated GPU for $35 in two years...that would be great!

I would like better N64..but honestly I would just like 3DO to work. As for Saturn or dreamcast...well that would be great...but honestly I think it's a miracle they can even run the handful they do on this Pentium 450MHz single core computer. And yes that is what it breaks down to it terms of hardware and yes it runs about (actually a little better) then the P2 400mhz with 128MB ram I have in the closet.

@lilbud I'd like to be able to not have to over-clock the pi to play n64 games.

You pretty much nailed it :) A better core would definitely help. It should have it... i hope! But it should also preserve a decent temperature with the standard settings. I suppose today's SoC can manage that.
So yeah:

More powerful CPU ( 1.5Ghz ~ 2Ghz )
More ram ( 2GB)
Support for larger and faster SD cards (thinking about those new ones at 100MB/s read and 90MB/s write)
Oh yeah and h.265 hardware decoder support would be awesome!

That's all i wish :)

Fruitybit

I tried looking up what the layers in the chip mean and how six would be better than four, but I've ended up more confused and with a headache. I need to sit down and just play some more... (Don't think the beer helps either!)

glennlake

@fruitybit I think what people are calling layers really mean cores. When you boot up a Raspberry Pi Zero or 2 you will see a single raspberry on the screen. This represents the single core. When you boot the Pi 3 you will see 4 raspberries across the top of the screen. This is for 4 cores. To take advantage of all the cores, the RetroPie emulators will need a complete rewrite by people much smarter than me.

Fruitybit

@glennlake I was aware of the four raspberries, if layers do equal cores then it could be good news indeed. I'll try to hit him up for more information;)

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.

The heat problem has already been solved on the cell phone end. The Pi foundation needs to stop using a chip with a 40 nm die shrink. That's huge compared to most ARM processors today.

akafox

Yes I know there is a way...gigabyte did

just the raspberry pi foundation needs to now..I have faith in them...just have to wait

(waiting sucks lol )

I agree with the majority. At least 2GB of ram and a processor fast enough to run all Dreamcast and Nintendo 64 games without any problems!

Happy for the existing ports to remain the same but move the ethernet port with all the other to the back and USB to the front.

An early 2018 release would also be ideal. The sooner the better.

It’s going to happen, but the board makers haven’t received prototypes yet, expected early part of next year, so realistically not till the end of 2018 at the earliest. No clues as to specs, so I’ve asked to be ‘kept informed’ of ANY developments. Got a lovely gift of pre-component circuit boards today, 6 per sheet pi3’s, may post a pic later if requested...

I quizzed him about the 4 layers thing I mentioned in this thread, turns out that’s the layers in the board itself - nothing to do with the chips mounted on it. If I can blag any board details when it comes, that may give an idea of what chips will be used.

So yay!! Pi4 is coming!! rubs thighs enthusiastically

@trailjacker I don't see 2 GB of ram being feasible with memory prices. I'm betting 1 GB with whatever budget processor Broadcom is making at the time, 1.4 ghz maybe?

Deltax5

Please be enough to run hi gan. I am tired of this input lag. 200 hz isn't a big jump I can easily overclock it that with a fan on it. But i guess a newer cpu with the same ghz is actually better but still.
I understand it needs around 3 ghz. maybe making a duel core with 3 ghz would be awesome or the people over there can do some tweeks to make it work propally. I guess there going to be on to us if they listen to us. THey really need to implement hi gan in emulation station .
I don't even think the emulators even use more then one core anyways. I may be wrong thou.
I was waiting on the next pi to get then they released the pi zero and got upset. I bought a pi 3. It's ok I guess, not anyware near perfect.
They should just make it the best $100 board it can be. Im fine paying 100 bucks if it's amazing. anything more I may as well get a cheep old computer.

You fail to understand the purpose the pi was built for. Higan requires at least a 3GHZ machine to even begin to be close to proper so I wouldn't hold your breath.

I read this in an article interview with Eben Upton. It's the most successful selling British computer reaching 10's of millions and I think the 3rd best selling computer globally. It will be interesting to see the specs hitting the 40nm ceiling, keeping backwards compatibility and a $35 price point.

"Fans will be disappointed to hear that the next iteration of the Raspberry Pi won't be arriving until at least 2019. Eben Upton, co-creator and co-founder of the Raspberry Pi Foundation, has previously stated the current Raspberry Pi 3 would have a minimum life span of three years.

There is a possibility that the new Raspberry Pi 4 could be delayed beyond this, as the Foundation has effectively hit the limit of what can be achieved using the 40nm manufacturing process. Upton hasn't given up, however, stating: "we'll get there eventually".

Given the problems facing development, there's still no word on the technical specifications likely to feature in the Pi 4. Given that the company is struggling to innovate with the current 40nm, it is likely we'll see a switch to an alternate manufacturing process, offering more efficient silicon.

As for features, the Raspberry Pi 3 already includes Bluetooth and Wi-Fi support, so we're unlikely to see any substantial networking upgrades. You can also expect the form factor to stay the same, given the team's focus on interoperability between Pi generations.

Ports are an area where we may see some real change. For example, Thunderbolt 3-compatible USB Type-C ports can handle power, data, and video transfer - meaning that one USB-C port could do the job of every existing input found on the Pi 3. They're also substantially smaller than full-size USB Type-A ports, which would allow the Pi 4 to have a much slimmer profile.

vzapo

Raspberry Pi 4 won't come out at least until 2019.

Long story short, Raspberry pi 3 still holds on pretty well and with the current tech there is not to much they can upgrade that would make a bigger difference from Rpi3, so they are holding on a bit with Rpi4.

Okay here we go...(in a nutshell)

Emulation does NOT run like the actual hardware and never will. In order to emulate you must load the software into ram..much like a PC no big deal right? Well that is incorrect. With emulation you must load the hardware and the software into ram thus eating up ram and making your computer slow. Combine this with "bad code" or hacks to get things to work AT ALL..well now you see the problem! That being said..if you are going to make an emulator more accurate it will cost more resources. When I was using DOS and got a faster computer I had to use a slowdown program to literally slow down my cpu to make the games not run so fast. The program was not written for a machine of that speed. So running a snes game on a modern PC "raw" would make it so damned fast you couldn't even play it.

Now let's talk about the pi...
First off the pi has a RISC cpu NOT a standard 8086 cpu. RISC stands for Reduced Instruction Set Chip. It is ARM-7 based just like the snes. But unlike the snes it does not have a extra sound chip to do sound..and it has to emulate hardware so it has to use all it's RAM to do what it needs to do (compare that to the snes that doesn't have to emulate hardware and had an extra sound cpu). Also understand that the raspberry pi 1 B+ is an equivalent of a 400 mhz computer. And yes it is. (I still have my 400Mhz computer with 64mb of ram and it runs about that well.) The pi 3 might be equivalent to a 600mhz but not that much more. ARISC does not do as many instruction set cycles as an standard 8006 cpu. Thus it runs much cooler but at a BIG cost of performance. That being said....

Lets talk about upgrading the pi..
First there are MUCH faster single board computers out there. Just look at your smartphone. Yes your smartphone. That is what the pi is. How much did you pay for it? I know it was NOT thirty-five USD. If you want better performance then you need to have a board that has at minimum three CPUs. A CPU (brain) A GPU (graphics) and an A[udio]CPU (sound) then the main CPU can be freed to do crunching of instructions. Which the 3DO, N64, Sega Saturn, and the Sega Dreamcast all had (in one form or another..which is why they are difficult to emulate properly) so they could do more. That would make the PI a "real computer" and give it a "real price tag"! One thing that the pi could benefit from is faster RAM...but again cost..and the PI is made to be cheap. That is the raspberry pi foundation's goal. (aside from the heat issue.)

So....
Yes you could get a cheap PC and get MUCH better performance. Besides when you add it all up (pi,case,power, hdmi cable,sdcard) it almost comes to 100 bucks anyway! That is NOT the point though. The point is just the coolness factor of the whole idea. (Try fitting a PC into a snes case!) The rasp pi was never designed for what we are doing with it. We are making the pi what it is. We are allowed to make the pi whatever we want it to be...thus why it it SO popular! Yes I would LOVE to see a more powerful pi and have it run dreacast games smoothly (note that PCs have a hard time doing that too!) and everything in between for "$35-ish". I'm crazy? Yes..so is everyone else (you KNOW you want that too! lol) One day that will come. For now I will complain and mumble..but truth is I am very happy with what i have because it is amazing what can be done with this thing at this price...here's to hoping that the raspberry pi foundation never losses sight of it's present goal..and here is looking to what they can do in the future! I might have to wait but the wait will be worth it!...(just hurry it up already! ;P)
