Inspired by the benchmark from Matt Dowle (https://h2oai.github.io/db-benchmark/), I compared his benchmark with GPU (Detail: https://lnkd.in/e7iHg7N).
For processing big data, GPU K20 2 GB is slightly better than 20 cores CPU Xeon 2.6 GHz 125.8 GB RAM, even much better in some tests 🙂 Of course, the performance comes with a price.
Thanks to Omnisci sales who gave me 12-month Standard 2 Free Trial which actually costs $495/month!
