1000 core chip that runs on AA batteries!
They claim it consumes 7 tenths of a watt executing 115 billion instructions/sec.
Interesting, not from a practical standpoint but to shows what's possible and maybe on the horizon. It sure would be the bomb, tho, to put several of these to work on our stuff. https://www.ucdavis.edu/news/worlds...processorchip It looks like they cut corners on the design all over the place ( cache, instruction set, FP thruput ( single precision only, of course), but still ......

okay that's about 6.086956 picojoules per instruction by my math so at full instruction speed in theory I get about 10.834782 joules used per second ( aka watts) but other than running multiple tests LL isn't parallelizable so it's only use might be TF or some other thing done in parallel.

FFT multiplication is (sort of) paralizable. Thus the good performance of clLucas/CUDALucas, etc.

The raw data is 0.7W and 115e9 instructions per second. All we can take away from that is that the power draw lies between 0.75 and 0.65W, with the performance lying between 114.5e9 and 115.5e9 ips. Thus all we can conclude is that the energy per instruction lies somewhere between 0.65/115.5e9 and 0.75/114.5 pJ, or between 5.6pJ and 6.6pJ. IOW, there's a good chance that not even the first digit you quote is correct. Why, then, do you state nine digits? That amount of precision is total BS.

Rather than giving six decimal points of meaningless precision, give a +/ on the measure.

I was just doing straight math from the given numbers. doing it from xilman's range of 5.66.5 pJ it gives 9.97 watts to 11.7 watts at full power rounded to 3 places.

Just think about the RAM bottleneck ...

So what magic do they use to transfer instructions and data into/out of the processors?
