Risc-V Laptop

Let's keep an eye on that. At worst, Haiku seems to have good RiscV support. I was on the edge buying a RiscV machine for it, seeing it run on 64 cores would be nice. But FreeBSD? What's the Chip in it, I never heard of it before. And they have single mainboards for Framework Laptops. That might be cheaper to check out.
 
Interesting. Over the last few years, risc-v has underperformed versus intel and modern ARM chips. It would be interesting to see a performance comparison for that machine.

I have the idea the major retail brands are avoiding the open hardware approach. We should have had boards with 64x64 RISC-V cores by now but they fear non-monolithic computers because it threats the market of disposable systems. Instead of buying an entire new mainboard with CPU and memory, people could just add cores and use them until they die of old age or a disaster.
It would be a joke if I can beat your latest Intel with only a specified quantity of identical interconnected microcontrollers.
 
the cpu has crappy performance like an android tv box. no way it is worth 560 euros. everything risc-v is trash, more expensive, slower and far less supported than x86 or arm.
 
It's from Hangzhou. I think it's probably part of the Chinese gov's program to develop RISC-V computing.

Tom's says the server version is pretty slow. They've branded that laptop chip an "M1'. Well, I wonder.

They've had various previous attempts over the years. Mips/Longsoon/Godson, and some X86 clones, some with the IP licenesed from AMD. They licensed POWER from IBM too, I don't know what happend to that. Probably a lot of what they develop never gets out to the west, it's a big country with a huge internal market.

I guess it has one very attractive feature if you happened to be paranoid about the intel ME, and what possible backdoors might be in the ME; namely, no ME. Or not an NSA-approved one, anyway.
The kind of thing that might find its way into battlefield or space-borne systems. And probably no SPECTRE, MELTDOWN, and other crappy intel bugs are present in that chip either.

I doubt they're intending you personally to buy it. The PLA might be putting in a big order, however.
 
About what I expected from reports of previous risc-v machines. However, if SMIC get their 7nm process node working, this thing could get faster. The US has an ASML export ban on them to try to slow them down.

Huawei Kirin is another line of CPUs under development in China. Maybe a competitor to this risc-v thing.

A few years ago, well, maybe ten... Elon was laughing at their early EV cars; he's not laughing so much now. Nothing works like having your government bankrolling your development costs with hundreds of billions of dollars.

China spent $230.8 billion over more than a decade to develop its electric car industry, according to the Center for Strategic and International Studies.

Watch this space, I guess.
 
I have a RISC based laptop ;)

Thread 'ThinkPad Power Series 820'

What are the chances of getting FreeBSD installed on my ThinkPad Power Series 820 which I managed to switch on today for the first time in twenty years? It has AIX installed but I can't login as I've forgotten the password :eek:

I can do a diagnostic test without logging in and it shows a failure under SCSI - not sure if that means the hard disk has failed.

Still haven't managed to do anything with it.
 
The current RISC-V machines are for early adopters such as operating system and compiler hackers. They aren't mean to be competitive in general spaces.

Having said that, it is annoying that you still can't buy a reasonable package builder.

PowerPC alliance is deader than a dodo, along with AIM. Who remembers Taligent today?

The modern version is open power, but it's aimed mostly at servers and embedded. China has been involved in that, too, of course. Companies like Raptor and Mellanox make POWER products that are somewhat invulnerable to X86 or ARM cyber exploits, which is what you need in intelligence and defence applications.
