Something that I find very interesting is that it is probable that some of the patent applications that Einstein evaluated were for methods of synchronizing clocks for railways. This was a pretty big deal at that time, and Einstein was prob

The nonzero transition band of real antialias filters is typically a way bigger concern than the strict equality of the Nyquist theorem.

The explanation in that paragraph is not necessarily incorrect, just confusing because it talks about voltage "in" wires and isn't clear about what two terminals are being referenced. It is true that the voltage between live

by twtw 9y ago
That is single phase. The "hot" (or "live") wire has a nonzero voltage relative to ground, and the neutral wire is usually around the same voltage as ground (do not count on this). The one-way plug ensures that the &qu

Alright, I understand better now what you are saying. I'm eager to see some benchmarks that can answer those meaningful questions. Thank you for your courteous reply.

I responded to your other comment to disagree, and I'll do so again here. Nobody is comparing DGX1-V to a single TPUv2 chip, because it doesn't make any sense to do so. they are totally different kinds of machines. But for some re

Another field that might be interesting to compare is analog design. There is a similar stack of theories: lumped element -> transmission line -> maxwell's equations. And yet analog IC design depends heavily on inherited mental m

It doesn't matter in the ways you are considering. The ultimate comparisons are going to be time, cost, and power to complete some benchmark, just as you say. I only mention the number of chips because loads of people are comparing the

Some things: A "single TPU" is 4 ASICs. It is not clear if it makes sense to compare a "single TPU" to a "single GPU." As a point of reference, NVIDIA's numbers are 6 hours for Resnet-50 on Imagenet when t

by twtw 9y ago
Why does it make any sense to compare the price/hour for a single TPU (4 ASICs) to the price/hour for p3.16xlarge, which has 8x V100? Also, that benchmark cost of $358 is for Resnet-152, not Resnet-50.

by twtw 9y ago
It will be interesting to see some benchmarks that compare TPUs to V100, since all previously published comparisons from Google compare TPU to K80 (3 GPU architectures ago).

It still mostly worked fine? In 2001-2002, S&P500 was still higher than it had been for all but 5 of the last 40 years (after adjusting for inflation). So it was far more effective than hoarding cash. 2008-2009 was slightly worse, but t
