Hi Castlenock
the main problem here is a VIRTUALIZED hardware and, if I remember correctly, the AC2 instances are 15-25% slower compared to the same hardware on your desk running without virtualization.
The Tesla GPUs are not the fastest ones, gaming GPU is faster by 20+% as it uses much higher clocks…
Try to look for a lower CPU core version with the same GPU count as too many cores bring no performance anyway… There are the Workstation CPUs that are aimed at performance, lower core count but much higher GHz…
While I may have to invest in that regardless, I’m also thinking of going another route and with my next build (if I get some business), and go for one of those 10 core intels on a z170 board with a 1080 ti or two once they are released. There would have to be some significant improvement over the same 4 core CPU / single GPU build though and I’m just not seeing it from my experiments.
A local fast PC will be always faster than a cloud solution… at least in the foreseeable future…
