All About BTC, LTC, ETH mining as well as other alternative crypto currencies
Just about three weeks ago GAWMiners have announced their upcoming Vaultbreaker Scryt ASIC miners – a 500 MHS model and a 250 GHS mini. Today they have announced an updated about these new miners saying they will offer 50% increase in the hashrate for all existing and new customers that pre-order a Vaultbreaker. So the Vaultbreaker will be 750 MHS and costs $6999.95 USD (Batch 2 pre-order) and the Vaultbreaker Mini will be 375 MHS and costs $3795 USD (Batch 2 pre-order). The expected shipping date is still the end of Q3 (optimistic) or early Q4 (realistic).
The initial prices for the Batch 1 pre-orders were $8999.95 USD and $4999.95 USD respectively and the 500 MHS miner was supposed to provide this hashrate at sub 1000W of power usage. So the new prices for Batch 2 are now lower and offer higher hashrate (Batch 1 miners should also be upgraded to the new speeds). The new hashrate of 750 MHS however does come with 1500W of power consumption and the 375 MHS Mini will be with 900W of power consumption. So the extra 50% increase in terms of power do not come from further optimization, but apparently are a result of additional chips. With the new hashrate however the Vaultbreakers do become more attractive alternative than KnCMiner’s Neptune miners, especially if they can deliver at the same time or even earlier.
