Is it worth investing in Vega for mining purposes, or should one just stick with AMD RX 580 series.
If you run a farm and can get rx580 for rrp then its the lowest cost for mining purposes. Vega is a card that will last longer for resale as games graphics card. Later on AMD will be releasing a special little Vega card to replace rx580, that is the card that probably mines the most for the least cost, it might be another 6 months before then
For short term vega 56 is good
but in long term vega 64 is best for me
I see on many forums vega 56 have problem with chip
I dont think 56 and 64 have great differences. Does mining benefit from 8 more shaders because the 56 isnt really slower apart from that
The HBM2 is lower binned and has lower voltage tolerance for 24/7 mining over 2-3 years.
The best binned HBM2 costs $150 for 8GB!
So you can guess; Samsung must have given a huge discount to AMD to use up Samsung's lower quality and less voltage tolerant HBM2!
This why, AMD can price RX Vega 56 at $400.
The main difference is quality and voltage tolerance of the HBM2 used.
