The post [Review] Antminer T9 vs. Antminer S9 – Who is the Bitcoin Bitcoin Miner? appeared first on 99 Bitcoins.

If you want to get up and mining as soon as possible and reliability is more important to you than efficiency, then we’d say the T9 is a reasonable choice. If you don’t pay for power and just want a good, fast miner you can “fire up and forget,” the Antminer T9 will fit the bill nicely.

If you’re willing to be more hands-on with your mining, then we’d say the forthcoming S9 miner will be the better choice, especially if you want that 180 day warranty. However, the wait for the next batch could prove costly, especially when factoring in likely shipping times from Bitmain in China.

If you’re money-conscious and don’t mind shopping around – perhaps even tinkering with a miner to achieve greater efficiency – then we’d recommend seeking out the right batch of second hand S9s, at the right price. If you can find them new that’s even better, but rather unlikely due to the high demand! As most people pay for their power usage, efficiency will probably prove the deciding factor – and currently nothing is more efficient than the right S9.

Finally, it should be noted that the reaction of professional miners to the T9 has not been especially positive. The general consensus appears to be that the T9 is a way for Bitmain to clear stock of sub-standard chips, by running them at higher voltage to boost their reliability. The downside of this is degraded efficiency.
