finally a good thread

It depends how botnet free you want. Cortex A7 is a solid option.

You have to recognize bloat is the jewish trick that plague computing with the demand of (((high performance))) backdoored hardware. FF doesn't even compile without 2GB ram (>>479). Vim and other program runs perfectly fine. You also should never in any case run Windows, which is a known spyware. If you must, set up an air gapped Faraday cage with the fastest botnet PC in it. But notice that you being trapped with botnet makes you part of it.

Scam to avoid: RISC-V (MIT), anything modern.

In a perfect world, there would be GPL CPUs. CPU designers would then have to really compete and improve, without compromising security nor freedom.

>Scam to avoid: RISC-V (MIT)

Please elaborate.

Vim is more bloated than Firefox.

RISC-V allow vendors to develop proprietary designs, if well adopted, would results in fragmented and vendor-lockin cpu extensions, compilers, and firmware. Or simply botnet.

No Fritz chip is mainly what I was going for because it completely kills all possible trust in the machine, but full freedumbs may be interesting to other anons as well. There's going to be a lot of overlap between the two aspects anyway.

The way you worded your reply makes it sound like the Cortex A7 is a tradeoff; what is being traded here? From the part on the A20 I'd think it's trading performance for less botnet in general, but maybe you just meant this particular SBC. TrustZone removes i.MX6 from the equation. The Talos looks admittedly juicy, but

>2.5K-6K dollarydoos

That is some price tag. It does seem like ~1.2GHz is about the most you can expect without going x86 or quintupling your budget, huh.

>You have to recognize bloat is the jewish trick that plagues computing with the demand of (((high performance))) backdoored hardware.

Ain't that the truth. I usually stay around a comfy 1GB of RAM with all kinds of shit open thanks to smart software choices, but as soon as Lardfox is open it spikes to 3GB. Fuck compiling the thing, I can't even use it on 2GB without constantly swapping like in the old Emacs joke.

>But notice that you being trapped with botnet makes you part of it.

It's how we even got into this situation. Nobody gave a shit about bugged chips when they first appeared and seven years later you can't get anything else, because "there is no demand for it". Apathy is really death here in the long term, and while it's late it's maybe not yet too late.

The compromise is maximum freedom without going full autist.

ARM Cortex A7 is not free. Allwinner is also very known for its GPL violation. Part of A20 still need blobs to function, fortunately, most of those functions are not critical nor necessary. As the chip is not completely free. There can be hardware bugs and backdoors laying dormant on it.

It can still run Linux, quite well. It is slow, but still reasonablely working with a well chosen array of software. The only game you ever need is NetHack.

What about the alternatives? If maximum freedom is absolute, being Robinson on a lone island is your best bet. After all, most people are botnet nodes. The law is also a well known part of the botnet.

One step above it is society without electronics.

One more step above it is electronics without computers.

Then, the most basic computer. That can be built on your own without any non-auditable parts. Much time, effort and money is needed. Even then, that computer cannot run any program other than what was specifically written for it.

The compromise is everywhere, because (((it))) is everywhere. Preserve. Anon, preserve. Because dawn only ever come after long nights, and welcome to the game.

We need to get all the high functioning autists to stop making CPUs in minecraft and start building them in real life.

>>956

The problem is that chip fabrication is really expensive unless you do it at scale. Your random autist can't just easily test his designs, mistakes are insanely expensive compared to software, and the entire business is self-centralizing; then once you are large enough you're a great target for the CIA niggers.

I vaguely remember a blog being posted here around a year ago of some hobbyist making his own semiconductors. Of course his process was large and his yields were ass, but it was mildly interesting. Can't find it anymore, unfortunately.

If you're willing to accept minor companies instead of hobbyists, I think Chuck Moore's (of Forth fame) Green Arrays Inc. also fabs its own stuff, but I can't find clear info on their site. Their chips are ~130nm.

FPGAs are an option for low-end shit, but FPGA companies' main business model is IP fuckery with (often Windows-exclusive) toolchains, so the FPGAs with free or reversed toolchains quickly go out of print.

>botnet-free CPU

>laughs in non-free firmware and botnet chips the size of a 0603 resistor

Stop using computers if you're that paranoid.

>I could go with the AMD FX series for the time being for that appears to be the most powerful x86 CPU without such cancer

According to this, Piledriver is the last architecture without pspoz: https://freundschafter.com/cybersecurity-cpu-and-system-alternatives-without-intel-me-iamt-and-amd-psp-secure-technology/

So if you are already going for a "budget" box by using ~7 year old CPUs, one of the APUs may not be a bad idea either. The FXs were powerhungry as fuck.

>>1036

I believe the APUs of the FX series do contain the PSP

>AMD FX

if you don't have the schematics, then it's not botnet free

>1GHz it doesn't seem like a great choice for a desktop

1GHz seems fine to me

>x86 would be preferred

x86 is botnet. period

There are actual open source CPUs out there. use them.

it's not impossible.
