Can you quickly explain me what this FPGA cards are? Im new to the subject.
Are they advanced GPUs for DC or VDI usage or are they something else?
-Is the mobo a especial kind of mobo or you can use any other components as normal Rigs?
-Do they use Win10 and any other normal driver/miner ?
Sorry for the noob questions!
FPGA=Field Programmable Gate Array
Put simply, they're somewhere between a gpu and an asic: they are application specific, but you can code the program, so basically you can use it for anything you can get it to do. It's more akin to a gpu in mining terms, but instead of specifying a miner and letting existing drivers and software to do the work (which includes powering and running aspects that aren't needed for mining, much less efficient as gpus are designed for, well, graphics, etc), you have to program the gates to do what you want. Which is why it can be far more energy efficient. Sort of. This is a really basic breakdown from a slightly-more-experienced-than-amateur coder who has only been reading up on FPGAs for a few months (and has only played with Intel test boards).
If you're interested in learning more, Intel actually has some really good basic guides available for free if you go to their FPGA product support pages (I think they even have FPGAs for Dummies linked there). It's a lot to learn. They're really, really fun, but there's a huge learning curve for programmers, much less for someone like me who is Linux proficient and knows a little C...
