spondoolies is offering some amazing cyber monday deals. Naturally all before new tech is announced shortly.
Those amazing deals aren't that much better - if at all - than an S4 with a coupon. Am I missing something here?
Power usage is a rather large factor.
Underclocking to prolong profitability.
Check their thread and search for reviews not by Dogie since he's a paid employee these days. More evidence ... check sales of bitmain gear on ebay. I was in favor of bitmain till they came up short on price when you include shipping per GH and power per GH. Resale value is a short curve also.
I think you're reaching here. I own a ton of Bitmain and Spondoolies gear. From S1 and SP10 to S4 and SP20. SP31 coming soon too. I like the wide range of Bitmain stuff, I like the tough rack-mounted Spond boxes.
I don't see a significant difference in anything that you mentioned. I just sold an old S1 for $65 to someone in Montana, probably going to use for heat over the winter. S4 undervolts just fine.
The point is, both are solid manufacturers, both made some boo-boos (S4 first batch, SP30 specs), both seem to be able to support their customers. No need to disparage one at the expense of the other.
If you want to look at shipping and specs, SP20 is $815 shipped to the US for 1.7 TH/s and ~1150W, needs a power supply.
S4 is $960 shipped to the US for 2.0 TH/s and ~1400W, no extra cost.
Very close as far as I can see, and it makes sense - I bet both of these manufacturers are watching each other's pricing. Long live competition.
How far can you underclock the s4?
As for Dogie, he is a paid shill. Best to ignore trolls like him and stick to the facts.
