RX 480 8GB speed 33 MH/S Power 80 watts

yeah right

No it was never 80 watts, most likely he is talking about the wattage that you see in GPU-z which is only the GPU chip wattage and doesn't account for the rest of the board like the memory controller, fans, and other components.

Honestly I don't think 33MH/s is easy with a 480 8GB, maybe some with a certain ASIC quality were possible but with my RX 470 4GB the most I could get was like 29.5mh/s and it wasn't really efficient. The best efficiency was at like 28.5MH/s and it still used 120 Watts per GPU from the wall not including the motherboard+drive+ram.

80 watts is just not possible with any RX 470/570.

rx 470 4gb you have elpida memory i guess yes they give you stable 29.5mhz but i have also rx 470 with samsung memory which gives stable 30.5-30.8mhz which is good for these cards.32-33mhz is easy to get with rx 480-580 with samsung memory an micron also doing not bad.

The RX 470/570 4GB came with either Samsung, Hynix or Elpida memory. I think the first batch was mostly Hynix and then some manufacteurs started to include Elpida and some higher end manufacteurs included Samsung memory.

90% of all my RX 470 4GB are Hynix and 10% were Samsung. The Samsung were the best because they gained usually 1-2Mh/s more than Hynix. The Elipida I heard were the worse.

The Samsungs were also good on other algos like XMR (the old XMR algo not current).

The issue is that before you actually buy and install the card, you have no idea what type of memory is included. With some models you can look and read the chip but others its covered and you need to use GPU-z.

My opinion:
Samsung worst (30,5mh only)
Elpida good (up to 33mh)
Hynix best (up to 33,4 - 34 mh)
