Not really interested in Gamers Nexus, I am still laughing at them when they made a big thing about putting an AIO on a Titan V and tweaked their setup to set some benching records. It took me one go to beat their scores with a standard air cooled Titan V because they did not know enough about tweaking the CPU memory.
You should not believe everything some of these tech sites claim, it is far better to test for yourself..
So you still are of the conclusion that hbm using lower power is a myth despite the fact nobody (besides you) claims otherwise?
