China Releases 2nd generation MIPS Chip 354

Posted by timothy from the cheapness-beckons dept.
eldawg writes writes with news of the launch of a second-generation Chinese 64-bit MIPS CPU. "The Godson-2 or 'Dragon' went into production last week. News reports indicate that, 'The CPU is 95% MIPS compatible using an unauthorized and unlicensed variation of the MIPS architecture, which is owned by the American company MIPS Technologies...The Godson-2 is pretty much a copy of the MIPS R10000 which makes it on par with 1995 technology.' The Chinese plan on using these chips in consumer electronics for the local market, but one can assume that they will eventually end up in exported electronic goods.

        A patent granted in USA is not automatically valid elsewhere, and you cannot infringe on a patent where it's not valid. The Chinese will infringe on MIPS patents if they try to export their chip to countries where the MIPS patens are valid.

        It does not implement the bits that are patented. IIRC there are patents MIPS equivalent of SIMD instructions and a few others. The chinese were wise enough to skip these so they in fact can export this and MIPS technologies will have to sit and watch.

        Do you have any facts about this, or is it your intuition?.

        It was one of the design criteria. There was plenty of information about it 1-2 years ago. It was carefully and deliberately designed around MIPS patents. The rest of the architecture and the instruction set is an industry standard and in the public domain.

        If the Godson-2 is "pretty much a copy of the MIPS R10000".

        It is as far as instruction set is concerned. It is not as far as technology and implementation. While R10000 was not a bad CPU, I would expect "Godson" to be considerably better. It should consume less and scale to higher frequencies. China has manufacturing capability on 150nm (and possibly less) which was not available to anyone in 1995

        1. This processor is 95% MIPS compatible. I understand incompatible, and 100% compatible. What do they mean by this?

        It could mean a couple instructions aren't implemented. This could be because:

        a) they had to avoid a patent
        b) some instructions were part of the original architecture, but were never used
        c) some better replacement was discovered

        It is relatively easy to strip out support for a couple specialty instructions from a compiler, so the usefulness of a "95% compatible" processor is perfectly conceivable.

        I'm just saying there's nothing here to suggest that it DOES. That's the whole art of "spin".

        3. If the Godson-2 is "pretty much a copy of the MIPS R10000" that seems to make performance claims (rather than just saying it's "MIPS compatible"). I'm not sure your Opteron-8086 analogy architecture analogy holds up.

        Performance is largely a function of non-platform-specific things, including having access to the latest silicon processes - and China does. Instruction set is not so relevant - we've gotten to today's performance mostly by heaping layers upon layers of pipelining and caching engineering on top of the original x86 instruction set so I think it's a fine analogy.

        Good catch that this is was a PR release.

        Who knows - there are tons of Silicon Valleyites who are just completely pissed about globalization and the threat of Chinese technology, so who knows the motive for this fine article.

      In the US, patents last 17 or 20 years, depending on the type [patentcafe.com]. And US patents aren't valid in China anyways.

This link -- the Lexra story [jonahprobell.com] -- is a good summary. From that article: MIPS Technologies claimed that because an exception handler could be created to emulate the function of unaligned loads and stores in software with many other instructions Lexra's processors infringed the patent. It was claimed to basically be a patent infringement case because the instruction set used the patented unaligned load feature.

    Learned a long time ago to ignore any political opinions given by computer scientists because agree with them and they'll just say the opposite. So after the whining about companies banning replication of their video codecs and software, it's now bad for China to replicate MIPS compatability.

    Nevertheless, compatability with the MIPS standard seems like the most trivial thing they could have copied. There are much harder problems to overcome in building a CPU than what spec to follow. The MIPS spec doesn't define how to mass produce very precise arrangements of semiconductor features for the least amount of money. It doesn't define how to dissipate heat and reduce power consumption.

    Also, one day people are going to figure out that whatever China's government says, it's 10 years behind their current status. China's government says its economy is only growing at 5%. In reality it's growing at 10%. They say they won't finish the olympic stadium until 2008. It's finished now. They say 3 gorges won't become operational until 2010. It's operational now.

    If you've ever used an R10k Silicon Graphics workstation, you'll know that these MIPS chips are pretty beefy. The floating point performance in particular on modern MIPS chips is spectacular. (R14k chips are used in Tezro currently)

    There's a REASON Silicon Graphics used MIPS chips in their systems until recently. (and they only switched to x86 stuff due to economic pressure, not performance...)

    I have a dual processor R12k SGI Octane on my desk and it still beats my brand new P4 out on a LOT of tasks. And that's a seven year old machine....

    Plus, these are 64-bit chips.

    Sure, the R10k processor is "from 1995". But SGI's policy at the time THEY were using MIPS R10k chips in their $50k workstations was to factor of ten beat everything else on the market. Meaning, their systems were engineered to be at least ten times as powerful as the competition (and ten times the price to boot).

    So... Knockoff R10k MIPS chips, built with modern advancements, smaller dies, and scaled to higher clock rates, will perform VERY WELL comparatively. In fact, for some tasks, (floating point) the chip should compete quite well with a P4 1.5 Ghz... and probably be a whole hell of a lot cheaper. And 64 bit I might add.

    And since there are already designs for systems with massive numbers of MIPS R10K nodes (Origin 2000 for example) which are considered to be "junk" it's not hard to imagine knockoff supercomputers....
