Loongson 3A5000 Benchmarks For These New Chinese CPUs Built On The LoongArch ISA

That's all you've got ?
At least he smiles far better than usual Ferengi clan:



Note trademark "Thetanus" smile.
Can't fake that.

It seems rather foolish to create a new instruction set architecture instead of just adopting RISC-V and get all that kernel support, compilers, toolchains, and all that already made just for free already.

Work started on Loongson in 2007/9 when MIPS licenses were purchased and design started. There have since then been several processors and architectural iterations. So it’s probably just a question of it predating RISC-V and them continuing along their chosen path evolving their arch, rather than suddenly dropping everything and starting over with RISC-V.

Is that a good or a bad thing from your perspective?
i mean, for us Europeans, it doesn't really matter if it comes from China or America. There's nothing wrong if the balance shifts. Actually, it already shifted.

I would say its bad. Currently, China leads as production centre, but West is still leader in technology. The xiaomi phones are in the end using snapdragon and ARM.

The problem with China is that, it has repeatedly exercised its expansionist policy blatantly, even with relatively little gain in power. It has a tendency to break international treaties, and just play dirty in global arena. The greatest problem with them is the idea of Han supremacy being incorporated in the only party that can exist there. All though none of the major powers have ever been angelic, I still think China is pretty much worse than USA and most European nations. Even Russia has not been as shameless in pursuing its whims as China

Who writes your texts ?What "expansionist policy" ?
Over that patch around their borders ?
Compared to which baseline ?

Any good examples that you'd care to share ?

Where does that show ?
In Africa, perhaps ?
There are plenty of mostly positive testimonies there for direct source - involved governments.
China has appeared as partner when IMF was preparing to eat them alive.

Just for comparison, this is what 14_EYES partners are doing across EU:

Humm, these benchmarks might be early stuff, without any optimization.
I can't really judge or compare MIPS, but the L1 and L2 caches look a little small; L3 is probably shared between cores. But then, I don't really know MIPS.
What would be interesting is to see if that thing shines on certain more optimized operations - and, of course, power consumption in conjunction with the overall speed. If this thing just uses 5 Watts, hey, the result might still be fine in comparison.

It is because you did not follow the discussion. It was uid313 who argued it was foolish of China not to jump onto RISC-V. I merely explained what Loongson copies from.

Well it is foolish, or at least lacking hindsight at best

It is nonsense of you to believe RISC-V could not compete with the desktop market by the way. We are already seeing RISC-V workstations and we are seeing Arm desktops, too. More is on its way. There is no technical reason why it could not compete. There is only not a lot of support, but rather a lot of politics at play.

Don't twist my words, I never said it couldn't. You asked that RISC-5 hasn't proved myself, I a said at least if you are looking at microcontroller/embedded it has. Of course it can be powerful for desktop but thats another kettle of fish (not even Sifive is aiming for desktop)

Anyhow, seeing how the thread has been evolving is there really just one thing I can add here: British tech rules!

Right, but I still don't see how all of your claims of licensing wrt to RISC-5 make any sense. RISC-5 is very popular in China specifically because its free of the licensing problems.

I mean you could have just said that they chose to make their own ISA because its very close to what they already have and so it takes less effort which is valid, but all of the other reasons you gave tbh is hogwash.

[uid313]

It is never foolish to make your own experiences. It is only foolish if it means you could fail at it or pay a too high price for it. Neither will be a problem for China, and making their own experiences will be a benefit to them.

RISC-V then still needs to prove itself and there is not much RISC-V on the mass market yet, but it has to compete against x86 and Arm first. However, Loongson is said to have copied much from x86 and Arm, but avoids licensing problems. So while China is making their own experience do they copy from what has already proven itself many times over.

While x86 has served us for a long time and continues to serve us, I don't think it is a good source to copy from when you want to create something new.

x86 has served us so long not because it is good, but despite that it is so bad.

i would prefer to not make this discussion in this forum too political, so it will be my last comment. I am referring to their multiple acts such as Tibetan invasion and their cultural destruction, Uighar cultural destruction at similar lines, multiple aggressions on Bhutan, Hong Kong debacle, and whole mess in South China sea. There are many more of their underhanded measures, such as funding of terrorist organisations against India, destabilizing democratic govts in Nepal and Myanmar and so on. Also i doubt there is any other major economy, USA included, that engages in citizen surveillance to the extent china does, with complete control over every social platform so that any criticism of CCP is never tolerated. These also enable systems such as their social credit system. I think there are so many multiple red flags, any sane person who values his freedom would be wary of them

When coping from x86 and Arm, because these are successful designs, is hogwash to you, then you have a severe comprehension problem.

[sdack]

x86 has served us so long not because it is good, but despite that it is so bad.

This is actually just your egocentric judgement kicking in. Anything that has survived for so long and despite people like yourself criticising it thinking they know better, is simply good by definition and because of your inability to actually change it. x86 is good, because it has out lasted all its competitors and critics.

If you cannot understand this, then you too have a comprehension problem and likely because you allow your ego to get in the way. I myself started with Motorola's 68k CPUs and was very reluctant to switch to x86. But I am still using x86 today and cannot help it, but find that AMD and its Zen CPUs are very fine processors despite it all.
