This *could change after 3000 series, but 5600 XT is king for a few

[alumar]

Did a 1.5h livestream last night going through a range of settings/configs with the 5600 XT 6GB using only the AMD Driver Tool. Results in video; bottom line 1300 core *800mv /w 1860M and -50% power limit = 75w of usage at nearly 39mh full card. 85w if you want 43.3mh. With a 30-50w System Power you could get 8 of those for 310mh @ 650w!

Yes and No. I personally went with RX5600XTs because RX5700s became EOL. Only a few RX5700 exist and no longer $300. leaving only 5700XT's for 380~. RX5700's/XT is better just for per hashrate and cost perspective. Good tuning can get 120W~ avg with 55mh/s.

But those watts are not at the wall.

I have used:

 5500xt
 5600xt
 5700
 5700xt

I can get 28 for the 5500 series at 63 watts
I can get 40 for the 5600 series at 84 watts
I can get 51 for the 5700.          at 108 watts
I can get 51 for the 5700xt         at 115 watts

those are all software numbers from my simple mining rigs.

prices matter. 

the best I can do for the 5500xt is 191-11 =180 each
the best I can do for the 5600xt is 244
the best I can do for the 5700xt is 349

and the 5700 is not easy to get anymore

all those prices are limited and include rebates and coupons.

I also do not push cards so squeezing every bit is not that import to me.

I rather under use them and they do last longer.

I can make an argument for any of them as long as they are a good price.

All of them are making money even if you have 20 cent power

I guess I'm lucky after buying my RX5700 last year. I've modified the bios to RX5700XT, undervolted it a bit and it's very close to RX5700XT, but not using as much power or heating severely like in others' cases. I've got a Sapphire Pulse and I'm very happy with it in my main rig

Yeah my guess wattage from wall per gpu is 105w. Total power consumption of 12x RX5600XT rig in Octominer 12x case+fans = 1450w total from Wall(PDU).

Based on your numbers, in terms of £/mh/w, the 5600xt is about 30% better than the 5700

TL;DR if you can get the 5700 for less than 1.3x of the 5600xt, then you should get it.
