The cost is based on the current ETH price, if it goes up by Jul, the next batches will be more expensive.
The real cost is 800 + 200 shipping (in US) + 130 ATX power supply, roughly 1100$ at the current prices, close to zero resell value.
The same efficiency as GPUs.
Takes less space. Huge +++
A lot of noise, around 80dbl ?
So it will drive GPU prices down until they reach the equilibrium.
This won't kill GPU mining, but the GPU prices should get back to MSRP, that is a good thing.
Exactly, thats a very good thing actually for the GPU mining market. Insane inflated prices going down. And don't worry this won't kill GPU mining. The hashrate is the same as one GPU rig. It would take really a lot of these heaters to kill ethash. I actually like this ASIC announcment. First time for everything.
