PPC ISA still has a 30% IPC advantage over x86 at equal density, x86 has a 20% IPC advantage over ARM at equal density, so yeah, for the same density and close to the same size die just using a PPC ISA instead of ARM ISA, you are looking at a massive advantage on everything but power draw and heat.

I agree, everyone wants Raspberry Pi to release a RISC-V, and personally I think that is exactly what the Raspberry Pi V will be. That Pico you maligned is a game changing microcontroller, however more importantly, Raspberry Pi designed the RP2040 in house, I’d be very surprised if they didn’t have a RISC-V design they were working on.

Yeah, went over 10k views over the time it was in the front page.
Getting this much reach is nice. I plan to try sending my next project there for exposure, too, once it is done.
That's the mystery asm I post once in a while.
Use open stack supported FPGAs instead. Accept the limitations in clock speed and density, in exchange for actual control over your hardware.
As long as you run non-bloated software, it should be plenty fast anyway.
Beware the V extension is not up to the draft, but an older, incompatible, version. So, long term, it'll become very unsupported. Of course, it'll still be usable w/o V, and there are no comparable chips in the market even without V. There's literally no SoC capable cheap RV64G chips out there other than this one, once it is actually out there. And it's gonna be cheap at $12, so I'm grabbing one regardless of V support.
This is for power users, developers and enthusiasts, not the general public.
From a developer pov, it'll be dramatically faster than using a cheap FPGA, and dramatically cheaper than getting the ~1k boards from sifive.

You’re describing humanity in general to be honest. Many people buy a Pi because they see “cheap computer” and have poor impulse control, or they are a Windows user who wants to branch out, try this “Linux fad” and want a safe platform with full hardware support.

There are people tho that buy and intend to use it for some project, and do.

I bought 2 Raspberry Pi 3 A+ models last week, to use in my Amiga 500 utilising the PiStorm project.

I have 1 Raspberry Pi 4 8 GB as a “workstation” and another as a server hosting a .onion and IRC, and yet another being set up to host Element.

Admittedly I have two Pi Zeros that are doing nothing, but I think one can be used as a PiHole, I just haven’t gotten around to confirming that.

I was thinking about it recently, about how I missed the first run.
And I'm gonna miss the second run, because if you don't have a design ready right now, it's simply not happening realistically.
This shit ain't easy, for someone who hasn't done it before. So the rush would be, with a working design for FPGA on hand, to go through the necessary steps to port it to the fabrication process rules (and learn to do that, while doing so...)

It would be a bit late to join that one now. But trust me, it'll be cool to have been to RISC-V relatively early, in a few years.
A SoC is long in the works. I have some peripherals but no CPU. Yeah, it's gonna take a while.

That's a cool machine indeed. 68010 is very underrated. The original 68000 is basically a buggy 68010. Everybody should have used the latter instead!

1GHz single core and not much ram (64MB? 256?). RV64GC + older than currentdraft V. Not Zen3 performance, clearly.
But still, a major upgrade from the microcontrollers or using softcores (typically topping under 100MHz) on cheap FPGAs.
>I really want to see RISC-V succeed
Me too. Consider >>81467094
>something for <$20 sounds really good
Yeah, no buying remorse when it's that cheap. The ~$150 BeagleV will no doubt be faster (2 cores, same clock, probably higher IPC, way more ram), but no V extension (old V better than no V!) and will lose value much faster.
I imagine next year there'll be a shitload of sbc-friendly SoCs with much higher performance, better peripherals and ratified V extension. BeagleV at $150 will then feel like a horrible purchase.

Do any of you gents have old PPC, MIPS, or SPARC hardware that you want to use older OSes like OSX, IRIX, or Solaris on but have tried to shoehorn newer opensource software on? I've done Gentoo on my old Powerbook G4 a year or two ago and it truly was dreadful compared to OSX 10.4 with Adobe CS2, MS Office 2008, and Final Cut Studio. I've been able to get Tigerbrew up and running, but the last GCC recipe was of 6. After installing it, I want to do a few better and grabbed GCC 11, but ran into issues with isl, so I've grabbed the latest of that, and ran into issues with libtool. How far back do you go so you can get MEME 0.231 running on hardware they've intentionally stopped supporting over a decade ago? Do you ever have to shut if off and wait a few days before you try again? I aint even mad right now btw. This is what I live for.

IBM solved the problem of resource utilization in a cluster by allowing all of the servers in the datacenter to share unused resources with servers that really need it.

I guess you could call it a kind of datacenter-level pre-emptable resources.
This one's for memory

What do you think about this approach?

Sadly no. All I know is what I screenshotted from the video.
ARM is not that old (ARMv8 is recent, and v9 very recent, tba next year).
Note RISC-V's V extension definitely is very good.
