Chinese Chipmaker Unveils 64-Core ARM Processor

<i>That subsequently prompted some speculation that the chip would replace the now-banned Xeon Phi processors in the 100-petaflop upgrade to the Tianhe-2 supercomputer, which was supposed to be revealed in June at ISC 2016. Given that the latter never happened, it’s likely those FT-2000&#x2F;64 chips were not deployed, or if they were, did not meet expectations.</i><p>Hmm..<p><i>Process:Manufacturing with 28nm process</i><p>And there you go.<p>Not sure if people are aware, but China doesn&#x27;t have any sub-28nm (or 22nm?) fabs. TSMC has some of course, but the Taiwanese government is very, very strong on keeping those plants in Taiwan (although they are fine with TSMC etc building less advanced fabs in China).<p>Until they get a process shrink on this, I think.. well, I&#x27;d like to see some independent benchmarks.<p>Edit: The Samsung Exynos 5433 (4 cores on a 20nm process[1]) maxes out at 3.78 GFLOPS[2] on selected benchmarks. Call it 1 GLOP&#x2F;core - I find it unlikely that this thing is going to get 500 GFLOPS with 64 cores, even with a higher power consumption.<p>[1] <a href="http:&#x2F;&#x2F;www.anandtech.com&#x2F;show&#x2F;8718&#x2F;the-samsung-galaxy-note-4-exynos-review" rel="nofollow">http:&#x2F;&#x2F;www.anandtech.com&#x2F;show&#x2F;8718&#x2F;the-samsung-galaxy-note-4...</a><p>[2] <a href="http:&#x2F;&#x2F;www.anandtech.com&#x2F;show&#x2F;8718&#x2F;the-samsung-galaxy-note-4-exynos-review&#x2F;4" rel="nofollow">http:&#x2F;&#x2F;www.anandtech.com&#x2F;show&#x2F;8718&#x2F;the-samsung-galaxy-note-4...</a>

It seems this was announced exactly one year ago, not today!<p>Edit: Though last year&#x27;s announcement was just the planned specs, perhaps the unveiling here is the prototype itself and not the concept.<p>[Chinese links] <a href="http:&#x2F;&#x2F;www.ltaaa.com&#x2F;bbs&#x2F;forum.php?mod=viewthread&amp;tid=364899" rel="nofollow">http:&#x2F;&#x2F;www.ltaaa.com&#x2F;bbs&#x2F;forum.php?mod=viewthread&amp;tid=364899</a> <a href="http:&#x2F;&#x2F;bbs.kafan.cn&#x2F;thread-1849400-1-1.html" rel="nofollow">http:&#x2F;&#x2F;bbs.kafan.cn&#x2F;thread-1849400-1-1.html</a>

<p><pre><code> &quot;FCBGA package with 2892 pins&quot; </code></pre> Yikes! Thats pretty dense on the other side, would love to see a picture.<p>It&#x27;s a 100 watts, so at 3.3 volts its drawing 30+ amps, so I&#x27;m guessing that a good chunk of those pins are power and ground. Is that a good theory?

At 500 gigaflops, I would buy these in a heartbeat if they were offered for sale to the public. While that&#x27;s only half the performance of a xeon phi, this is a traditional CPU which makes programming it much more straightforward. Not to mention that the cost would be significantly less.

I wonder how erlang would work on this, especially in a multi-coprocessor system.

I guess that&#x27;s what happens when you forbid Intel from selling to China<p><a href="http:&#x2F;&#x2F;wccftech.com&#x2F;us-government-bans-intel-nvidia-amd-chips-china&#x2F;" rel="nofollow">http:&#x2F;&#x2F;wccftech.com&#x2F;us-government-bans-intel-nvidia-amd-chip...</a>

This appears to a global-cache-coherence chip.<p>Slides 12-16 <a href="http:&#x2F;&#x2F;insidehpc.com&#x2F;2016&#x2F;08&#x2F;phytium-china-unveils-64-core-arm-hpc-processor&#x2F;" rel="nofollow">http:&#x2F;&#x2F;insidehpc.com&#x2F;2016&#x2F;08&#x2F;phytium-china-unveils-64-core-a...</a><p>Each 8-core &quot;panel&quot; has its own L2 and DCU The L3 is globally shared, with the usual cache coherence protocol. 30ns latency for L3 hit.<p>I am not an expert on cache performance, but this certainly seems like an up-to-date design.<p>Can anyone compare this to Xeon and Phi ?!

Sounds cool. Does anyone have any benchmarks to get an idea of what this processor can actually do?<p>A price would also be nice.

I fear for Intel, AMD, and the US semiconductor industry. This is not competitive with Xeons <i>yet</i>, but it will be.<p>On the other hand this is good for the future of computing in general. The worst case scenario would be for things to stagnate with no competition, offering no incentive for anyone to push beyond traditional Moore&#x27;s law type scaling.
