This is quite interesting. Has Pandaminer said anything about upgrade options when new GPU's are released into the market? Can this rig be upgraded to preserve some of the investment?
it is a good question.
This is a good unit
the imac uses
AMD Radeon R9 M395 graphics processor with 2GB of GDDR5 memory
Configurable to AMD Radeon R9 M395X with 4GB of GDDR5 memory
http://www.apple.com/imac/specs/so these are rx 480 they could be possible upgrade for the imac.
Before the RX 480s, my first "high end" card was the 390s which was at least a "1 year old' card when I bought some and thats was end of 2015 during the ETH hey days.
The 390s today is still quite an impressive work horse, very much the same as their 290/290x generations before that but with faster memory. Both are power hoggers though...
Then came the Polaris cards, 480s and 470s were nice because of the price-point, lower power consumption, decent hash power and easily rom modded further to get that extra juice.
I think the 480 will still be around in a year or two, unless the 490 / Vega series is quantum leaps ahead of 480s in terms of core clocks and high speed memory - which we need, in the memory intensive top coins. A optimised undervolted 480 rig today can already dip well below 150w or lower TDP per card. So 480 to 490, how far more can it go.... I doubt if everyone will queue to buy 490s to replace the 480s.
IMHO, I think 1-2 years from now, I bet the 480s are still the workhorses of GPU farms, just like their 290s/390s did prior. The only difference now is how low can the power consumption go still -- at what MHs performance ratio.
Maybe the more experienced miners can feedback.... because I know a number of them have brought back their Scrypt/LTC rigs of yester-years from the dead and still got decent $$$ mining ETH, ZEC and XMR.
The 480 powered Pandaminer I think will be worth investing and keeping for at least 1-2 years in the mining game, unless something drastic happens... like the unexpected rise of CPU mining.
Anyways, this is just my observation from mining just under 1.5 years now.
Appreciate comments from more experienced miners out there.
Have a great New Year 2017 and have safe holidays ahead!
I would think the cards in here do not need an upgrade for at least a year to 16 months.
for me getting an english windows 10 will be important. I am not going to try until monday.
it is in my garage and is not nasty sound like the s-5 s-7 s-9 from antminer.
So my fears were hot and loud and chinese gui.
it is under 90f to the touch. a plus
while loud the pitch is lower then I thought it would be so a plus
chinese windows 10 is driving me nuts. biggest flaw for me.
Do I think it is good yes assuming they ship them to you on time.
They did do the no risk shipping to me and they will not do this for others . I still have yet to pay for it.
lets see if some known people that ordered get theirs timely.
lets see how they hold up. for a bit.
but the size factor is really good. the heat seems good.
I am yet to test the stock psu it is 220-240 volts only.
Do I recommend it yes but we need to understand down side.
Short warranty.
Chinese windows 10 is very hard to make fully english _______ this just may be my stupidity but I did read some windows 10 software builds will not allow full switch to english. only a mix.
we do not know how fast they will ship to you.
If I had a 3 cent warehouse I would want a lot of these.
I am pretty sure I will keep it. So I am selling gear to pay for it.
