what do you suggests if we want to achieve something around 1.5 terahash/sec?

thanks


almost yes


Do you already have the hardware?

almost yes

OT: How does scrypt run under nVidia/CUDA? Are nVidia GPUs better at mining LTC?

http://en.wikipedia.org/wiki/CUDA

Got the 3.5 from the Compute Capability Table, hence the slight confusion there. I'm not expecting miraculous results due to the differences in architecture between the ATI and nVidia cards in general, but would be nice to try and find a way to squeeze a bit more out of the nVidia cards just for kicks.

To do those speeds, it be more realistic to get the next batch of ASIC's coming out.

To compare GPU wise you'd need 2000-2500 Radeon 7970's. I'm not sure I want to figure out how many Nvidia cards that would be, but most likely just multiple that 2000-2500 by 4-6 depending on which card you get. Buying 10,000+ GPU's will cost way more than it's worth ($3 Million).

However an Avalon ASIC, running at around 60-65 GH/s ($1300-1500), would mean you'd need around 20-25 of them to get to 1.5 Th/s.

Clearly it is more cost effective you can buy ASIC's.

If you haven't actually bought the CUDA cards yet ( you said nearly yes), I advice you do not.
Unless you actually have another reason to buy CUDA cards, outside of bitcoin mining.

I know CUDA cards, are very popular in Render farms and simulation programs, but these are not good choices for Bitcoin.

as read on internet,the titan card has around 3000 cores

so even with that there is nothing we can achieve with it?
