If these are cheap and people can run a lot of chips at once then this could be a game changer. I want a few hundred myself. lol.

the price of dev boards and chips so far is not cheap, but not fixed. they will sell at the price people will pay for shovels, supply&demand..next machine contains ~208 chip for total ~12/mhs scrypt and 330g sha256 or 450g sha256 and 8mh/s scrypt depending on mode

Any one know more about this chip?


specs are here

https://github.com/gridseed/gc3355-doc/blob/master/GC3355_DataSheet.pdf

And holy shit, it claims to do 59.6 KH/s while using 0.44 W

This is 0.00738 W/KH/s versus 0.300 W/KH/s for a GPU -- a 40.7 fold increase in efficiency.  This is about the same increase in efficiency as compared to BTC when ASICMINER first introduced its chips; I'm curious to see how they did it.

electricity efficiency is awesome. put me in for 10 units.
the domain is still not ready.

My understanding of that GPU is ~750khs per card. Which runs about 300$. Energy consumption, by massive amount yes. Price will be based on kh per unit. We will be selling @ 0.90$ per khs (Which we have achieved in relation to profitability.) As for kh/s, easily and with only a single unit. Our conservative numbers are 960kh/s with 3.5 watts consumption. I would say we have beaten its numbers pretty thoroughly.

That would be around 75W for the same result with the GC3355 plus some pocketchange in btc

scrypt requires a memory bank, doesnt it? where is that going to come from for this design? every other scrypt asic has talked about the need for high-end DDR5 memory, and lots of it

24" PCI-E cables with 16AWG wires and stripped ends - great for server PSU mods, best prices https://bitcointalk.org/index.php?topic=563461

OOPS, I'm a little bit late to this thread.

Hey senseless, which code are you using for LTC? Thanks a lot

Mine probably https://github.com/kramble/FPGA-Litecoin-Miner though senseless should confirm.

The code gets around 16kHash/sec on a LX150 with 4MBit RAM, TMTO LOOKAHEAD_GAP=4 and 16 threads. Or 60kHash/sec on a ztex quad 1.15y board. Its not the most efficient implementation, but its the best I've come up with to date. Someone with a bit more expertise should be able to push this up a bit (it only clocks at around 64MHz and 30% LUT utilization).

Coincidentally the spec quoted for the Gridseed device per LTC unit is pretty much identical to my results, so its certainly possible, though they will probably be clocking it a lot faster and using less RAM overall.

Woah!, Now i wonder if Litecoin is going to crash, or skyrocket from the network now having Litecoin mining chips.
Im intrested to see how this turns out... and weather or not i should buy some "cheap" litecoins

It's likely that ltc price will rise as more people spend more money to mine it, similar to bitcoin. It'll also have more people materially invested in the coins talking about them, also the same result. If Bitcoin price raises to $5k, people will want to get on the next profitable coin. Maybe ltc goes to 250-500.

I think LTC will be a good invest.

People mine Litecoin, because it's not Bitcoin.

If I had to buy an ASIC to mine Litecoin, why would I bother, I might as well just buy an ASIC to mine Bitcoin.  Roll Eyes
