That article is irrelevant. You cannot know the exact type of memory installed on the GPU, but empirically.
I have 2 models from that list:
a Palit Dual GTX 1060 3GB, equipped with Samsung memory - about 20 MH/s stock, 23.8-24.6 MH/s overclocked (22.5 MH/s in the article)
a Gigabyte Windforce GTX 1060 3GB, equipped with Hynix memory - 15.5 MH/s stock, struggles to get to 19.1 MH/s overclocked (25.2 MH/s in the article, assuming it's Samsung memory - a great result)
My 2 satoshis about hashrate:
Lyra2REv2 - 26 MH/s
Palit Dual GTX 1060 3GB AMP (Hynix)
Power Limit 100%
Core Clock 2050 MHz
Mem Clock 3007 MHz
Hshare - 7.9 MH/s
Palit Dual GTX 1060 3GB AMP (Hynix)
Power Limit 100%
Core Clock 1987 MHz
Mem Clock 3499 MHz
