External GPU for gaming, with bitcoin miners.... it is possible

**DiogoSaraiva** · December 29th, 2014

Hi,
Is possible add some GPU power to my computer with these usb bitcoin miners which are usefull for bitcoin mining?
if possible, how?

Thanks in advance

It may be possible, but most Bitcoin miners use pretty powerful video cards (usually ATI), and I doubt a USB graphics stick is powerful enough.

I have a mini PC (Giada A51B), and I guess it GPU is 512 Mb...
These bitcoin miners USB are 336 Mh/s so i will become with 512 + 336??
Or maybe not... is different units... Mh/s... Mb.....

So, Can you explain me?

Thank you very much

anyone??

Why do you think this USB key has a GPU on it? The purpose of this key is calculating hashes and not rendering games.

I don't remember why... but I think because I hear about that Graphics Card can Mining bitcoins, or so...
so Graphics card can mining bitcoins but bitcoin miners can't render games, is this correct?
Know you other way for render games? for more Graphics Card power???
by the way: what I can do with these bitcoin miners with their "calculated hashes" instead the main purpose (generate bitcoins)?

Thank you very much and have a nice day

Graphics cards are good at mining bitcoins, because they have a lot of tiny cores which are very efficient in manipulation of some data. Bitcoin miner ASIC also might have multi cores, but they are intended for mining only. Without this, their hash rate/watt would be much higher and mining would not be worth it. So you are probably out of luck.
