The new Raspberry Pi 4 is here!!
-
@shadow Tom's hardware's review seemed to imply that 1.75ghz is currently the limit determined by the firmware. But perhaps that will change

@frezeen Not sure about the comments of it struggling with Youtube. Chris @ ExplainingComputers.com released a video today and it seemed to playback Youtube full screen without an issue. The benchmarks do seem so verify what he said 2-4 times faster depending on what you are doing.
His video is here for those that are interested.
Just watched that video now and seeing that the GPU is 256mb gives better hope that more emulation might work a lot better and also holding off on buying one right now until there is a new image for RetroPie for this cause i would really like to do some emulation testing on it especially for the more demanding arcade games out there because it would be interesting to see if some games like Tekken Tag Tournament and Tekken 4 work on it as well as other games that you had to overclock the Pi 3B+ for it to work .

@Ecks A Pi3 already works with GPU memory set to 256mb, that's not something new. The increased GPU memory (if I understand correctly, limited to 1Gb) would help the front-end more (Emulationstation/Pegasus/Attract-Mode) than the emulation.
-
@shadow Unless somebody also writes ARM drivers for those external GPUs, and drivers for the Pi to support eGPUs, and probably a bunch of other things that would be a crapton of work creating software that doesn't currently exist, to create a "solution" that costs 10x more, but works really poorly, then I'm not sure we'll be seeing that anytime soon.
ETAPrime on Youtube has the LattePanda running with eGPUs. It's neat if you happen to have the stuff sitting around and want to do it. That's about it.

A quick Googling suggests ARM was claiming a 28nm A72 core could hit 2.5 GHz. ARM seems to me to be notoriously optimistic in their PR regarding new cores. I couldn't find any actual clockspeeds in shipped products in my brief search. And, of course, those would be in different SoCs, containing different other components, with different frequency/voltage curves than the RPi4's, so it wouldn't be directly comparable. I'll probably look more later.

@dd0ck I already use a NAS with my older RPI. CD games are not all loaded at once so are fine.
-
@Jiryn You'll have to dremel your case already for the Pi 4, so it's just a little more dremeling for this setup. :)
-
1gb, 2gb or 4gb memory best for emulation? (I ask this as is there a limit to what emulation can use?)
-
@paffley Emulators itself don't need much system RAM, so increasing it won't help. More memory can help with other things like the frontend (EmulationStation). My advise is to get 2gb if you really want to use it for emulation with RetroPie only, or just the 1gb if you can't justify the 28% increase in price, while the performance in emulation don't change. But having more (4gb) won't hurt other than your pocket.
-
Perfect answer! Thanks @thelostsoul that answers my question! :)
-
I was also thinking more on the lines of N64 performance, I didn't want to purchase the 2gb version if the 4gb would be much better for this system (wait 5-6 days for 4gb release). But from what I gather its more the n64 emulation correct? than the power of the unit itself? :)
-
Excited about this.
-
Someone mention Sega model 1&2, IIRC that model1 (or 2 that where my memory loose accuracy) run really poorly on pi3 (daytona usa was like 7-10fps with some glitch) any chance, on paper, of an improvement?

on what emulator? if it was MAME, then the CPU is 2-4 times the performance of the pi3, depending on the situation, and MAME is CPU based, so assuming that is the bottleneck, i would expect a good improvement, but it's probably still going to be glitchy. maybe a later version of MAME is viable. really need a specialist model 1&2 emulator becoming open source... doubtful.

-
@Thak it does seem like it's abandoned unfortunately. known glitches in basically every game. so yeah, glitches will remain but i would expect better performance.
-
@dankcushions damn... That's too bad :'(
-
I would really rather have a full sized HDMI port than 2 micro ports, but other than that, this looks really exciting. 4k hardware h.265 decoding is something I've wanted for awhile, and the memory options are great. Can I assume this will run much cooler than the 3b+?

Hard to say (from my perspective). If you aim at same performance, then it will be cooler for sure. If you run it at its full potential, I would assume its a bit hotter, because its consuming more power. Here is a full review and first look, testing the heat too: https://www.tomshardware.com/reviews/raspberry-pi-4-b,6193.html
Yes, this board gets warm, warmer than its predecessor. Thermal images mirror what we experienced; the areas of the board near the CPU get really warm, not just the top of the processor itself. The Pi 4 board reaches a toasty 74.5 degrees Celsius (166 degrees Fahrenheit). That’s not enough for a serious burn, but kids especially should be sure to pick up the Pi by its sides only. The top surface of the Pi 3 B+ is much cooler, maxing out at 62.5 degrees Celsius (144.6 degrees Fahrenheit).

Looking forward to being able to turn on the rewind feature for PS1, which, on my 3B+, slows things down to a stutter. I've been wondering if it had more to do with processor limitations or memory bandwidth limitations?
Something to look forward to down the line. I just finished putting together a retropie this spring, so I really should just enjoy it for a while, at least long enough for case designers to release updates for the new form factor :-)
-
I understand that all the ports aren't in the same spot but is the board the same size and are the 4 screw holes in the same locations? I run my pi-hole in a stacked pair of cases and it would be nice to just remove the old board and replace it with a new one when I upgrade that particular pi.
Actually that would be useful for at least one of my Retropie builds as well
