Block Erupter: Dedicated Mining ASIC Project (Open for Discussion)Update
Our RTL design, optimization and simulation are finished. We have some data to predict the specification of actual chips after they are manufactured.
Hashrate: 1.25GH/s per chip
Area: 17.5mm^2 per chip
Power Consumption: 13.3W
Note that they are calculated from the front-end design and not accurate enough. But of course the possible difference range won't be large. We will keep our updates.
