I think he's kind of speaking past the original author. The original piece is basically about how the author doesn't think that RISC-V will take off outside embedded, because of some design decisions that lead to poor performance compared to ARM64 and because so much of the ISA being optional means that there's too much fragmentation to make binary distribution feasible. Meanwhile, this piece is mainly about how RISC-V is great for embedded because companies can build it into custom chips with specifically the functionality they need, and because of how cheap it is for low-end use cases since there's no license fees.
The only real point of contention I see between the two is that this piece goes on to talk about how it's a selling point that RISC-V can be used for both low-end 10 cent microcontrollers, and high-end multi-core processors running Linux. Personally I don't see the benefit of this since you're going to have to recompile your software anyway, and since all the RISC-V SBCs I'm aware of have significantly worse performance and efficiency than comparably priced ARM SBCs.
The huge number of companies building RISC-V chips and really crazy optimizations that they are doing in all kinds of spaces are a very real counterweight to your notion.
And RISC-V is just starting here with shoestring design and fab budget. Wait till all engineering teams really adopt it like Tenstorrent and NextSilicon and so on.
> Personally I don't see the benefit of this since you're going to have to recompile your software anyway
The benefit is a unified toolchain. Make a chip, get the entire software toolchain for free.
In the past if you made your own chip you had to write your own assembler, compiler, debugger, etc. Many manufacturers forked gcc but of course it's still a lot of work and the license isn't great (for them, not the user).
This universal compiler toolchain is massive benefit for both the chip makers and the end user.
Different RISC-V dialects might as well be as different from each other as English is from German. Sure, the cognates, family the resemblance, and common(-ish) alphabet make some things easier, but if you're shipping a manual, you still need to do it both in English and auf Deutsch unless you rely on machine translation.
So it is with the family of mutually incomprehensible ISAs called RISC-V.

Seems to me that the difference between a 10c chip and a $1 chip are a rounding error when the shipping cost dominates so much?
I’d really like an explanation here if the author is reading. And how does shipping cost scale with quantity? Can you get that to be small per unit on big orders?
I don't think the Author disagree with what the original article wrote. If anything everything he said seems to reassert what the original article intended to state.

> The students I want to teach are in the same position, and so are the ones in Nigeria and Bangladesh
It does not take $60 to ship small sub $1 chips from Asia to Nigeria/Bangladesh. These two countries are all on global trade routes (both supply and demand) and the expensive last mile delivery costs are fairly low there too.
Is this comment on shipping costs from Asia to Nigeria/Bangladesh based on your experience? If there is a less expensive way then share the approach to help others :)
i don't know how trustworthy rateships.com is, but according to them shipping costs to nigeria and trinidad are similar. and as for the last mile, the cost probably goes up because local shipping is rather unsafe (higher rate of theft of packages).
It could be bureocratic barriers. For example, Turkey recently changed importing laws so that anything(even stuff sent to you for free) from outside the country is subject to tariffs & import costs. Importing a cheap component worth 1$ costs like 300$.
> It does not take $60 to ship small sub $1 chips from Asia to Nigeria/Bangladesh
So don't even try to find how expensive is bring these to Brazil. Even the $5 orders from JLCPCB become infeasible for hobbyists here due to all the roadblocks.
I am in Asia, this means nothing, it's the largest continent on earth. I don't pay as much for shipping as the author does, but his struggles are nevertheless relatable: most sellers refuse to ship here, most of those who do want dozens and dozens of dollars for it, and some (few, usually Chinese) sellers save the situation from being completely hopeless.
In my experience, people in the United States often (incorrectly) short hand East Asia as Asia just like the people in the city of New York will often (correctly) short hand New York City as New York.
> In my experience, people in the United States often (incorrectly) short hand East Asia as Asia just like the people in the city of New York will often (correctly) short hand New York City as New York.

Ironically (for my generation in the UK at least) "Asian" meant "South Asian" and for a long time we didn't have a useful shorthand for "all parts of Asia"

HN hasn't been Bay Area centric in years. Honestly, most comments and usership on the platform seems to now align with DACH and CEE.
Presumed RISC-V hate is a perfect example of that - the UCs and CSUs have been using RISC-V in their curriculum since the 2010s becuase Patterson is faculty at Cal and most CompArch courses in both systems have been using RISC-V as a result because 61a/b/c are often used as the benchmark curricula wise. An entire generation of Californian computer engineers have been RISC-V fluent as a result.
The hivemind assumption that HN's user base is "venture capital", "tech bro", "founders", and "Silicon Valley" is around 5 years out of date.
Anecdotally, the vast majority of younger (below 30) founders, engineers, VCs, and builders in the Bay have either not heard of HN or quit it within weeks due to toxicity.
>HN hasn't been Bay Area centric in years. Honestly, most comments and usership on the platform seems to now align with DACH.
I honestly do not get this at all. HN remains very US-centric to me, and especially centric to the mindshare of the Bay Area's IRL conversations, and apart from some takes on tech rights, does not really remind me of my experience in DACH.
As someone from the DACH region I very much agree with this. I don't see a shift from typical US opinions to opinions often held in the DACH region. Not at all.
> I honestly do not get this at all. HN remains very US-centric to me, and apart from some takes on tech rights, does not really remind me of my experience in DACH.
The majority of HN's usership, posting, and comment activity occurs during peak EU work hours (3am-9am), stylistic patterns that are common for German-native speakers are increasingly prominent, and the fact that IRL conversation topics in the Bay Area tech scene are entirely different from those on HN shows a massive divergence in userbase.
HN "Who wants to get hired" threads are a good example of that as well.

1.) I doubt 99% of Europeans work during 3am - 9am
2.) At least there can be other reasons:
2a.) EU times and African times are basically the same and Africa has a huge population.
2b.) India is closer timewise to EU/African time zones
2c.) What are about posts afterworks?
" RL conversation topics in the Bay Area tech scene are entirely different from those on HN shows a massive divergence in userbase. "
Any proof?
Though it feels a bit strange that "I have exceeded the allowed number of requests. (500 times)" when I first clicked the article and I'm pretty sure I don't share the ip of my self-hosted VPN with anyone.
Maybe. I'm not sure if the original author's intent was to improve say how risc-v could be better or to say it is bad and people should use other (proprietary) ISAs instead.
Yeah the complaints in the original article are valid, but it's like complaints about Android or iOS. There are plenty of valid complaints against either, but neither is strictly better than the other.
"Now price the same journey on the other side, forget x86-64 and that duopoly, patent minefield, with multi-thousand dollar debug probes; we'll take a look at ARM."
The 386 and 486 patent should have expired more than 20 years ago. No one tried to open source it. https://github.com/EI2030/Low-power-E-Paper-OS/blob/master/0... There were many companies that had clones in the early 90s, and I wonder whether any of them still have the rights to manufacture them.
" That is a better reason than elegance. and I want to tell Mr Grinberg, that the word priviledge he tosses around in his article also extends beyond the ISA depending on where you are in the world."
Grinberg is an emigre from Ukraine, which isn't the most privileged place in the world. In fact his research articles go deeper than the average software developer in Silicon Valley.
There are 386 and 486 open source reimplementations in Verilog (see z386 and z486). As far as I know, existing commercial 386/486 chips still manufactured (yes they exist!) are descendants of Cyrix work, not Intel or AMD. Consequently, VIA may be contractually holding those back rather than Intel/AMD doing anything there.
Thanks for that information! I have been interested in getting x86 produced in smaller nanometer (e.g. <32nm). My project: https://ei2030.github.io/FemtoTX/#about
"Intel provided Rosaic access to an unknown Atom-class core, which enables the company to build its own custom processors based on x86 general-purpose cores, according to the report. The renowned chipmaker plans to ship Rosaic register-transfer level (RTL) code for the Atom processor core, which will let the startup build its custom system-on-chip (SoC) both at Intel Foundry and elsewhere."
What's interesting is that a startup with limited funds would most likely seek a 32-bit x86 license if a) they don't need more than 4GB of RAM, and b), if they don't want to pay AMD for the 64 bit license add-on. :)

> Baochip. A VexRISC-V with an MMU built around a stack thats open from silicon to os Baochip-1x: A Mostly-Open, 22nm SoC for High Assurance Applications
Uh, which one of these is a datacenter server cpu? Or a workstation cpu? Or at least a developer laptop cpu? How about a Raspberry Pi 4 level SBC (supporting latest ubuntu and fedora releases, driving a display that runs a browser and plays video ...)
There's a lot of angry indignation but it seems obvious that Dmitry is quite right about this.
But I found this is where this blog post starts making a lot of sense:
> Has anyone tried adding an MMU to a Cortex-M? The physical tradeoffs are real, the difference is that with RISC-V, the ISA owner does not decide for you where that boundary must be drawn. If you want virtual memory on ARM you license a Cortex-A instead, which is a different core family, a different profile, a different negotiation, and a different royalty.
> Compare what happened with Baochip. The RISC-V privileged specification defines supervisor mode and Sv32 paging as optional things an implementation may provide. VexRISC-V is an open core, somebody added an MMU to it. bunnie built a chip around it and runs a microkernel with real process isolation on it
Yeah, that is a good point. We're still in the low-end specialty realm, but that is real interesting advantage for RISC-V, a good reason for it to exist.
As for shipping to Trinidad and Tobago ... this post is trying too hard to turn this into moral issue, but it seems a bit random (OrangePi cost $30 and shipped free? you can also get arm-based and stuff from the same places), and the vast majority of people don't live on semi-remote islands, it doesn't make sense to consider this kind of accessibility above all else, and it's strange to blame Dmitry for not thinking of you here.
Just an unlucky spawn point. We need to focus on ourselves. "oh no shipping to some remote island is expensive compared to NYC that has next day free on everything" Well, duh.
Naïve take. We live in a global neoliberal economy, our standards of living are the direct result of introducing scarcity and other forms of exploitation elsewhere while keeping domestic populations largely unaware of how unfair their position is. There is no ethical basis to simply "focus on ourselves" here. We must do the exact opposite.
Let’s take the rationalist approach, then: does the author of this blog post seem like someone who could contribute reasonably to humanity’s future? Does it seem like we might be doing ourselves a disservice by ignoring them, and those like them?

yo this is actually some really fire reading. i had to read it twice then go back and read the original that he's responding to here. i feel full of wonder right now seeing people who are this deep into compsci debating merits in the marketplace of ideas, there's just so much going on globally with computing that i never even get to see. super fascinating to read about the different constraints at play here even the global socioeconomic ones and how they apply to the chip world in general. it sounds like risc-v's real play is democratizing access to the entire embedded stack

This is a bay area centric take on a non bay area centric take.
The typical bay area centric take has the following vibe:
1. I am among the group of most open minded people
2. I admit mistakes, but I don't change my view, that means I may make the same mistakes next time on a different concrete cases
3. Morally I am among the least corrupted
4. I work for the moderately morally questionable firms with nice paychecks, but my moral views are not tainted a bit
5. I never think on the other's perspectives
As exemplified in the following series of essays

Bangladesh is a country in Asia...

I don't pay as much for shipping as the author does, but his struggles are nevertheless relatable: most sellers refuse to ship here, most of those who do want dozens and dozens of dollars for it, and some (few, usually Chinese) sellers save the situation from being completely hopeless.
In my experience, people in the United States often (incorrectly) short hand East Asia as Asia just like the people in the city of New York will often (correctly) short hand New York City as New York.
It's an interesting evolution given that Asia as a term started out meaning just the westernmost tip of current-Asia, ie Western Anatolia.
Slight correction, people in NY refer to it as “The City” and people in NYC say the same, but specifically mean Manhattan.

We aren't the only ones, but we are the loudest about it, because erasure sucks.
Don't get me started about Macedonia.
So is Ireland.
I don't think they are necessarily asserting otherwise
So what does it mean to ship from Asia to Bangladesh? Do you ship from India, Iran or Indonesia? Or just within Bangladesh? :)
Shipping from Asia to Asia doesn’t make much sense
Asia is a pretty big place

Bay Area != US
The Bay Area is its own microcosm of culture and philosophy that diverges significantly from much of the US.
Not making a statement on how prevalent either are on HN, but Bay Area is very much not equivalent to the US.
As an American, it’s extremely Silicon Valley centric, at least in mindset.
Extremely. The valley/startup lens is absolutely the dominant one.

I like to encounter discussions about German digital health system or the German start up system or neo2. I've never seen them so I doubt it.
Also almost no debates about Polish stuff (Hello neigbours!)
How is it not tech bro centric when every third thread is about some new feature of a random Anthropic product?
the fact that this comment is getting downvoted into oblivion instead of discussed is poignant enough.
fwiw, my experience is similar. hn has not been about startups, vc funding, or anything in that space for quite a while.

Well, this place (wherever you are) is like a memory of the world we used to love, and the memory is fading... Definitely true too.
You can't expect a place tightly connected to a changing world to stay the same.
So, you are calling the author a liar?

To me it feels like the difference in positions is "this could be made better" vs. "but this is already so much better than before". Both are right.
Maybe I'm missing something important so far...
Maybe. I'm not sure if the original author's intent was to improve say how risc-v could be better or to say it is bad and people should use other (proprietary) ISAs instead.
I was thinking the same. RISC-V is certainly impressive and I'm glad we have it, but the original article isn't wrong in its complaints either.
It definitely could have gone with a less abrasive tone (as entertaining as it is), so it's no wonder it's getting some pushback.
Yeah the complaints in the original article are valid, but it's like complaints about Android or iOS. There are plenty of valid complaints against either, but neither is strictly better than the other.

Uh, which one of these is a datacenter server cpu? Or a workstation cpu? Or at least a developer laptop cpu? How about a Raspberry Pi 4 level SBC (supporting latest ubuntu and fedora releases, driving a display that runs a browser and plays video ...)
There's a lot of angry indignation but it seems obvious that Dmitry is quite right about this.
But I found this is where this blog post starts making a lot of sense:
> Has anyone tried adding an MMU to a Cortex-M? The physical tradeoffs are real, the difference is that with RISC-V, the ISA owner does not decide for you where that boundary must be drawn. If you want virtual memory on ARM you license a Cortex-A instead, which is a different core family, a different profile, a different negotiation, and a different royalty.
> Compare what happened with Baochip. The RISC-V privileged specification defines supervisor mode and Sv32 paging as optional things an implementation may provide. VexRISC-V is an open core, somebody added an MMU to it. bunnie built a chip around it and runs a microkernel with real process isolation on it
Yeah, that is a good point. We're still in the low-end specialty realm, but that is real interesting advantage for RISC-V, a good reason for it to exist.
As for shipping to Trinidad and Tobago ... this post is trying too hard to turn this into moral issue, but it seems a bit random (OrangePi cost $30 and shipped free? you can also get arm-based and stuff from the same places), and the vast majority of people don't live on semi-remote islands, it doesn't make sense to consider this kind of accessibility above all else, and it's strange to blame Dmitry for not thinking of you here.
More than half the article is AI slop. Sad.
That is just an amazing website and initiative.

Does anyone have an archive?
The author of the article just got a fan.
Some serious stuff he builds on top of those chips.
Just an unlucky spawn point. We need to focus on ourselves. "oh no shipping to some remote island is expensive compared to NYC that has next day free on everything" Well, duh.
So “you were born somewhere ‘unlucky’, that’s how it goes, sucks to be you”.
Is that really your take?
Naïve take. We live in a global neoliberal economy, our standards of living are the direct result of introducing scarcity and other forms of exploitation elsewhere while keeping domestic populations largely unaware of how unfair their position is. There is no ethical basis to simply "focus on ourselves" here. We must do the exact opposite.
Appeals to an ethical basis don't work on everyone
Let’s take the rationalist approach, then: does the author of this blog post seem like someone who could contribute reasonably to humanity’s future? Does it seem like we might be doing ourselves a disservice by ignoring them, and those like them?

Edit: y’all really don’t like being told you should care about other people, huh?
yo this is actually some really fire reading. i had to read it twice then go back and read the original that he's responding to here. i feel full of wonder right now seeing people who are this deep into compsci debating merits in the marketplace of ideas, there's just so much going on globally with computing that i never even get to see. super fascinating to read about the different constraints at play here even the global socioeconomic ones and how they apply to the chip world in general. it sounds like risc-v's real play is democratizing access to the entire embedded stack
