Title: Litecoin for FPGA ?
Post by: PoorGirl on June 04, 2012, 06:22:42 AM
Hi Guys,

I read about FPGAs like the X6500 but wonder why all the code written for these micro-controllers target Bitcoin and not other similar eCurrencies like Litecoin ? My Excel tells me that for Litecoins I need less Mh/s to reach a target of x USD per day revenue. Besides finance, what limits FPGAs to mine for other coin-types ?

You have a good point here..

You will not get the same Mh/s mining LTC that you do for BTC on any device. Thus, mining Bitcoins on any current FPGA is more profitable, and is the sole currency people are buying FPGAs for.

ie, you may get 360 Mh/s mining BTC on a 6950, but the same card will only yield 0.4 Mh/s or 400 Kh/s if mining Litecoins.

I'm not even sure if the current FPGAs can run the script for LTC mining.

wow, FPGA for litecoin, that could be a nice thing

Well, maybe you are right. Its 500x easier to generate 1 LTC compared to 1 BTC.

So in 1h = can make 500 LTC
Same as 1 BTC with same hardware

Sell Value is:

500 LTC = 1,27 USD
1 BTC = 5.2 USD

So while I can make 500x LTC compared to 1 BTC the final USD value is 4x lower ..

Hence it's better to mine BTC and buy LTC if you (really?) need them. My understanding is that it is even better to mine LTC on a GPU, i.e. the whole "CPU friendliness" of LTC is gone.

It's still very easy to mine LTC on low spec CPU's.

Just don't expect to be getting rich off of it. This is why the GPU hostility was so good for LTC, everyone and their grandma could make some and have fun with the whole "crypto currency" idea.

Once the Bitcoin GPUs begin to migrate, that'll no longer be the case  :-[

It's also very easy to mine bitcoin on low spec CPU's.
Doesn't mean it is profitable.

I'll second that, especially if you have a lab full of computers that sit idle 95% of the time.

But which one is more profitable?

I did CPU mine on a netbook to see how things work and with the out of the box settings the LTC miner did 4
KHash whereas the BTC miner did 2.

The rate LTC to BTC is somewhere factor 500.

How to make sense of all this?

So with the new cgminer release does that mean I can run it in --script mode on my FPGAs?
