AWS G3 instances quick benchmark


(Alex) #1

Released couple days ago AWS g3.4xlarge instances based on Nvidia Tesla M60.
They have 16CPU and 122Gb RAM at cost of 1.14$/hour on demand.

g3 looks to be much faster than g2 generation.
They are slightly better than p2 instances on Cats and Dogs model, but from performance/price perspective - p2’s are still more suitable for DL.

Cats & Dogs (batch_size=64) :

I can confirm this result. Quick benchmarking from my end -
Each epoch in lesson 1 was taking around 588 seconds on P2 & 460 seconds on g3.4x large. 22% increase.
Each epoch in lesson 2 was taking around 605 seconds on P2 & 456 seconds on g3.4x large. 25% increase.

And this blog - http://kaggler.com/keras-backend-benchmark-theano-vs-tensorflow-vs-cntk/ also confirms that M60 (g3 instances) is faster than K80 (P2 instances).
