In the days since Bitmain announced the AntMiner R4, we have wondered whether the machine really performs as advertised. After some hands-on time with the R4, our first impression is that it seems to achieve the balance of power, performance and noise output Bitmain was shooting for.
Disclosure: AntMiner R4 was provided to review.

AntMiner R4 First Impressions
The R4 and the new APW5 PSU look like they could be an impressive pair. From a distance of 3 feet in an average-sized living room with an ambient temperature of 74 degrees Fahrenheit, the R4 and APW5 put out a combined 51 dB of noise.
The AntMiner R4 also runs at the specified 8.6 th/s, while achieving that relatively quiet 51 dB. Here are the specifications that get you to 8.6 th/s at 900 watts with 51dB:

Power Consumption: 845W +9% at the wall
Noise level: 52dB (at an ambient temperature of 35°C)
Chip quantity per unit: 126 x BM1387
Rated Voltage: 11.60 ~13.00V
Product size: 515mm (L) x 100mm (W) x 222mm (H)
