There are not the SoCs you are looking for; wavy hands.
1. Linux support
2. Likely accept small volume orders
3. Way more powerful than omap5
4. 1.5x better than A72
Seems all around worth a look. If not it's cool

Nice PR stunt you got there, it would be a shame if something happened to it...![]()

RISC-V (open source) and 1.5x better than an ARM a72
Hopefully it’ll get better with future updates of this board: https://www.cnx-software.com/2020/0...pen-source-alternative-to-raspberry-pi-board/Nice PR stunt you got there, it would be a shame if something happened to it...
You're talking about a startup there whose most powerful product on the market (the devboard costs 1k US$!) still gets absolutely mutilated by those ARM CPUs, only trust their words as far as you can throw them.
Yesyesyesyesyes... But can it run Crysis?Speaking of risc-V board but not really about a future SoC for Pyra needs (but this is still the best thread for this post, I think), the Indians have produced a new RISC-V core which they claim ...
RISC-V is a chip for those who think Linux on Arm is not obscure enough to be cool.
Yet, I don't think we want an FPGA as our next Pyra CPU, do we ?
To be quite honest, I think having FPGA tech on the next Pyra CPU board would be great. Obviously we'd still need a main CPU. But if we could get our CPU to dynamically set an FPGA depending on what system we are emulating, then that would be awesome. Not sure if FPGA tech (and powerful enough) is sufficiently small enough for this to be useful yet, tho'.

My opinion on this whole topic are :
Why do whe need a new CPU Board yet?
Thanks for the info. I figured as much as the $250 Ultra96 board needs a 8V 3A PSU.The UltraScale+ (not to be confused with the old UltraScale chip family!) gets way too hot, though, even if you don't use the beefy FPGA on that chip. I've been working with one of those beefy 10k € evaluation boards for a while some time ago.
Open source communities generally built their own source if they need to. That can be done on the Pyra too, but there's a bigger problem IMO. Certainly for games and emulators it's not just about can it run, but can it run well. I might expect some hypothetical future pyra cpu to be throttled to fit into a similar power envelope, so actually they might not behave so differently in practice, something more like a 600MHz Pandora (that can be overclocked stably to about 800MHz) versus a 1GHz Pandora (which can be overclocked a little above 1100MHz). Then again you've also got problems if the next chip supports Vulkan while our existing chip is a little over OGL2-ish.I tend to think that free software communities tend to mix and match and can use the contributions of other groups for new hardware, so fragmentation could not be so much of a problem in freedom as it could be in proprietary platforms, but it's still a lot of investment without having yet recovered the first investment. so no hurries.Let's get the Pyra out first, then grow the software ecosystem a little, and then we'll see.
I think the thing is, we have no idea how long it would take to release a new CPU board, so it might be valid to get a head start on it. If it takes two years, by then new use cases could arise where the current CPU just won't cut it. I'm afraid it already is a bit short on the video side.We don't, I agree. I'm not sure whether we'll ever need another CPU, but surely we don't need it now.My opinion on this whole topic are :

Soon enough many houses will be equiped with 4K screens, especially in the tech enthusiast communities we're a part of. So being able to output 4K from the Pyra's HDMI out would be great. And as more and more software is multithreaded and not requiring high clockspeeds, more cores would also be a nice thing. This is just two of the current CPU's limits, we might not feel constrained by its limits yet, but that doesn't mean there are none.
I'm a tech enthusiast, but not like that. This laptop I'm typing on now is 12 years old, and similarly my video server is of a very similar vintage (at least according to the CPU date; it was second hand). I like being able to do modern stuff on old kit, and I never buy things just because they're the newest shiny. I buy infrequently and try to buy the best when I do so that it'll last me. The Pyra was something of an exception to that for me, but I enjoyed the journey with the Pandora once I actually got one in my mitts and my Pandora was a bit tired by the end. The Pyra should be closer to the ideal of something the lasts for me.especially in the tech enthusiast communities we're a part of
