Litecoin mining speed

[iPaulito]

Can someone please explain me how can someone achieve 15 000 KH/s mining litecoins when according to this https://github.com/litecoin-project/litecoin/wiki/Mining-hardware-comparison if you have 2xAMD 7990 you achieve 2 250 KH/s and cost is $1K for just one card.

As I understand it correctly there is no posibility of mining SCRYPT based currencies with ASIC so how is it done??

Thank you for your time

AFAIK ... you cannot mine LTC with anything but GPU and CPU.

Which I think is great. Gives us little guys a chance in the digital coin world.

I am sure someday there will be an asic equivalent for LTC.  But lets hope that does not happen for a while!

Getting only 250Kh per card seems a bit low. I'd guess more like 750.
But some ppl rent a warehouse and stack 30 mining rigs in them. That should get you close.
Checkout some pools: http://www.wemineltc.com/statsAuth Top miner does 140.000 KH/s. That is about $100K of equipment.

Multiple computers, one mining account. Simple.

Yeah that's not the speed of one rig, it's probably at least 4 or 5 rigs.

i don't think a 7990 can mine only 250, more toward 1mh
