Yes, you can buy ASIC hardware that make current mining hardware useless.
http://www.butterflylabs.com/ Sells units ranging from 5GH/s to 500GH/s. They designed their own chips/hardware. I have a unit sitting 4ft from me that's doing 31.5GH/s and using ~110W. Website appears to be down atm?
https://terrahash.com/ Sells units ranging from 4.5GH/s to 180GH/s. Uses Avalon chips on a K16 board (developed by BKK and other members of this forum). Avalon chips are well tested, but are not shipping yet.
https://www.kncminer.com/ Sells units ranging from 100GH/s to 400GH/s. Uses a custom 28nm chip developed by ORSoC. They are still working on a prototype, and are obviously not shipping, but so far seem pretty legit.
https://megabigpower.com/shop/ Sells units ranging from 25GH/s to 400GH/s. Uses a custom chip developed by BitFury, who used to write bitstreams for FPGA mining back in the day. They have a prototype, but have not shipped any units yet.
Then there are Avalon units, but those are not being sold anymore. Instead the people who started the Avalon project are new selling chips for the likes of TerraHash and other companies. And lastly there is ASICMiner, but they primarily focus on selling shares for their own mining efforts. ATM they own ~20% of the entire Bitcoin Network. ASICMiner also sells mining hardware, ranging from 300MH/s to 10GH/s, but they are WAY too overpriced to even talk about here.
Hope that answers your question.
