RISC-V and framework laptops are my little spark in the dark that is proprietary tech.
I hope these open technologies go far and beyond

Quake is a "very old game" now? You make me feel old.
@pleappleappleap Says:
So.... you've ever booted Linux an Alpha or Mainframe or MIPS or PA8000 or 68k or PowerPC or POWER. or Itanium, or SPARC?
There are even stranger ones like National Semiconductor NS32532 and the IBM Cell (the Playstation3 CPU) that can boot Linux.
@AndrewTSq Says:
First I was into Risc-V but then I start reading about modular ISA which sounds like the reason why this will not be anything big. From my understanding, it means I can develop a software on my cpu with instruction set A.. and give the software to you where you miss a few instructions, so these will be emulated instead. I guess Risc-V will be perfect in closed systems if this is true, cause then you dont have this headache. But if its true, it will be like when MMX came for example, and you could not run this software cause your cpu lacked the instructions. But I could have understand it wrong

Looking forward to the VisionFive 2! Though it's hard to get right now, since the Kickstarter just ended end shops are sold out everywhere.
@volodymyrdobrovolsky8610 Says:
The RISC-V does not contain innovative ideas in microprocessor design capable of replacing existing processors such as x86 and ARM. The RISC-V processor is not suitable as a candidate for this role. They say “RISC-V does not represent new technology”. The RISC-V has no novelty potential. The tomorrow’s world needs completely new architectural ideas as familiar processors x86 and ARM are morally obsolete architecturally. I propose the novel architectural idea, see my article, address is below in this comment. The RISC-V is good for embedded systems, controllers, and similar as free and open. There are other positives and improvements, but they are on the engineering level. But the RISC-V will never become a general all-purpose processor. The RISC-V is based on 40-year old ideas as RISC-V Foundation claims. There is no sense to port the huge x86 and ARM software ecosystems on it. Thus, RISC-V will never gain a victory over x86 and ARM. The most of positives about the RISC-V processor are arbitrary speculations. Actually, the main advantage/benefit of RISC-V is free and open architecture (open ISA). The RISC-V processor has instructions with variable lengths, consisting of 2-byte snippets. It is strange, it is bad being a deviation from the classic, absolute, and pure RISC principles well formulated at the beginning of the RISC era. Also the RISC-V processor has 6 instruction formats, and it is too many.
I sceptically evaluate the RISC-V microprocessor, because it is based on old ideas and does not advance computer science and practice, freezing the long-achieved scientific and technical levels. However, I pay tribute to the creators of the ideas of the RISC microprocessor, with the main feature to perform all arithmetic/logical operations only on registers, and use external RAM only to load/store processed data. I also pay tribute to the idea of the free and open computer architecture (not patented instruction set architecture).
The Contemporary microprocessors contain 8 specific hardware components: (1) SMT (Simultaneous Multithreading), (2) register renaming, (3) instruction reordering, (4) out-of-order execution, (5) speculative execution, (6) superscalar execution, (7) delayed branch, (8) branch prediction. These components make up some kind of a “magnificent eight” of components which essentially raise the performance of microprocessors. But unfortunately they are very complex. A processor core having these components is a full-fledged one, otherwise it is good for simple applications, e. g. for embedded systems, controllers etc.
The “magnificent eight” of components is very hard to design, only the experienced firms and developers are able to do this, and much know-how was acquired, some effective solutions are patented. Particularly complex is the SMT. Only powerful and advanced firms like Intel, AMD, IBM are able to equip their processors with the “magnificent eight” components. It is not surprising that some Intel processors, and the famous Apple's M1 processor do not contain SMTs. If a company is able create the full-fledged RISC-V processor with all “magnificent eight” components then it would be a serious achievement, and such RISC-V would be considered of the World's class comparable with x86, with ARM, but not more. As far as I understand most of the developed RISC-V processors have no components from the “magnificent eight”, and are intended for embedded systems.
A course directed on further development of RISC-V is a wrong way, and leads the computer architecture to deadlock. The RISC-V is not promising for computer industry. In fact, RISC-V hampers the further development of the state-of-the-art microprocessor technologies. The World demands absolutely novel microprocessor having much more higher performance than all contemporary ones. The novel and effective ideas on computer architectures do exist! Here’s such a novel processor architecture in article V. K. Dobrovolskyi. “Microprocessor Based on the Minimal Hardware Principle”. The article is published in scientific magazine Electronic Modeling (Електронне моделювання), 2019, vol 41, No 6. pp. 77-90. The magazine is posted in the Internet:
https://www.emodel.org.ua/en/ touch ARCHIVE, move to 2019, then to VOL 41, NO 6, (2019) then click Microprocessor Based on the Minimal Hardware Principle, then go below to Full text: PDF, and click PDF.
My novel processor architecture does not have the “magnificent eight”, The “eight” is not necessary at all. This comment reflects different view on the RISC-V architecture, and the computer community has a right to become familiar with such a view. I’m Volodymyr Dobrovolskyi (V.K.Dobrovolskyi).
@first-thoughtgiver-of-will2456 Says:
I wonder if the simple architecture will allow for significant overclocking and/or high core count like the IBM series. Very exciting and I think philosophically from a computer science perspective RISC architectures with emergent instruction composing are superior to macro ops and CISC. If ever we change from silicone based chips to something futuristic like graphene, it is likely the first architecture will be RISC.
@rajakegelapan8498 Says:
new VisionFive 2 has launch, hope can see the review soon
@MnemonicCarrier Says:
Here's hoping an 8-core 2GHz version is released in the near future :)
@leeyk8006 Says:
RiscV only has benefit in the ISA. ASIC needs various costs like IPs EDAs fabrication pacakaging and so on. Briefly, It needs abundance of echo systems of FPGA or easy asic (this may be too much) with open eda environment. And FPGA board with open risc v, npu, gpu HW source would be the wanted but too far.
@gunnargunaxe Says:
Hmmmm... new and fresh open hardware 2 core computer vs old and fully optimised 4 core arm... Interesting 🤔
@NetRolller3D Says:
Alright, watching this video - that's *definitely* a Radxa. Exactly the same packaging style as the "Developer edition" Rock 5Bs, except with a black background instead of green, to match the PCB itself (final production Rock 5Bs have a slightly different design on the paper sleeve, but Dev Edition is exactly like this).
@dand337 Says:
Deepin 23 has just released RISC-V image. Could you try it out? I wonder if such cpu will handle full featured desktop.
@1000wolfdogs93 Says:
#ExplainingComputers Try getting distrobox up and running on this; maybe even try installing arch, through distrobox.
@Oktokolo Says:
So is it fully supported by the nonexperimental mainline vanilla Linux kernel?
@phrtza Says:
Impressive. I did not expect to see Quake running that well.
@etmax1 Says:
The interesting thing is that the US courts ruled back in the day that an ISA could not be patented/copyrighted which is why we had AMDx86 and Cyrix x86 and Z80 mimicking 8080. Where RISC-V differer from ARM is that the entire VHDL used to design the architecture is open source. They could have done RISC-V with the same ISA as ARM but then they would have faced much more detailed comparisons on there performance I'd wager. I saw someone do some benchmarks between RISC-V and ARM and ARM came out slightly on top, but I would imagine as a community develops behind RISC-V that the VHDL improves the differences become less pronounced.

@ExplainingComputers: I don't really get SBCs. All I see is a cheap Linux box. If I already have Linux on my existing system then what is the point? Perhaps you can explain that? :)
@tedcalouri2694 Says:
How much of the delay you experience is the processor and how much is a result loading from a flash card I wonder?
@RinksRides Says:
$200 is low cost for a SBC?!
@eamoralesl Says:
I started using Linux because where I worked (circa 1997) we used and sold Sun and Axil workstations and since getting one of these workstations for my house was impossible, I started learning a *nix flavor OS and bringing the knowledge to my work, too bad open Solaris died otherwise I would've loaded this SBC with a Solaris based OS just for the nostalgia and fulfillment of owning a RISC workstation with Solaris. ;)

@gabrielevidali Says:
So Europe should go this way instead of hosting Intel factories?
This is quite amazing - I can't wait to see what comes out of this!
@EdFrench_uk Says:
It'd be good to do comparisons of power consumed by these SBCs rather than the recommended as that needs lots of headroom. I am curious if there is a significant power penalty with riscv as sbcs often have power constraints.

@messengerofiexist2139 Says:
The way a computer functions has not changed since the first CPU’s were made. The limitations were money, the greater the number of registers the higher the cost.
Does risk-V include division? :D
