Bitcoin ASIC Machine A921 20T/S Canaan Avalon Miner SHA256 mining
BTC
PRODUCTS INTRODUCTION:
canaan avalon A921 chips are evenly distributed on two parallel
metal plates on a single hash board. 26 chips are designed on a
single metal board, so the number of chips on a single hash board
is 26*2=52. There are a total of 104 internal chips in the machine.
The chip arrangement interval is sparse from the air inlet to the
air outlet. The surface of each chip is coated with thermal grease
to improve heat dissipation efficiency.
Avalon A921 focuses on the convenience of heat dissipation and
ventilation when designing the mining machine, and the layout of
the computing board and the number of chips are therefore more or
less limited.

ABOUT THE ASSESSMENT:
The actual performance of Avalon A921 in this test is: the
computing power is less than the rated level by 2.8% and the power
is higher than the rated level by 14.3%, both of which are within
the official error range. The energy consumption ratio is 17.6%
higher than the official data.
From the perspective of a single error, when the measured computing
power is lower than the rated value, the measured power is higher
than the rated value. Although there will be force majeure
interference test results in the measured environment, but
according to the current test results, Avalon A921 The performance
can only be said to be more in line with the rated parameters given
by the official.
Q&A:
