Spondoolies-Tech Promises More Power-Efficient Mining

By Danny Bradbury, Coindesk.com

An Israeli company launched a bitcoin mining system this week that promises to eventually double existing power efficiencies. Spondoolies-Tech is touting mining rigs that will offer up to 2.1TH/sec per kilowatt of energy today by the summer.

The company has designed an ASIC chip that it says can achieve a similar performance to the design currently used by ASIC mining manufacturers such as Cointerra. The difference, says Spondoolies-Tech cofounder Guy Corem, is the process node; Cointerra uses a 28nm (nanometer) ASIC chip design, whereas Spondoolies-Tech uses a 40nm design.

The process node in a computer chip is the resolution of the components on the chip. Smaller numbers mean a higher resolution, and hence more microscopic transistors in a certain area. This has two benefits: it increases the speed that the transistors can operate at, and it also lowers the power consumption.
