Antminer T15 disassembly evaluation

Antminer T15 disassembly evaluation

On November 8, 2018, Bitmain released marketing information, announcing the launch of its first 7nm chip Antmiminer T15. It supports the SHA256 algorithm and has two versions: high performance and low power modes.

Miner parameters

model	high performance	low power modes
hash rate	23TH/s ± 2%	17.5TH/s ± 2% ~ 21TH/s ± 2%
energy consumption	1541w ± 7%	1050w ± 7% ~ 1260w ± 7%
power efficiency	67 J/T（25°C condition）	60 J/T（25 °C condition）

Exterior

Packaging: No logo on the top, shell size: 486*388*265mm, with ZEUS logo tape around it.

Unpacking: Remove the EPE foam on the top; you can see that the T15 has changed the ESD package, which is different from the S9 series.

Miners in the box: The power board is integrated with the miners, and the dual fans are parallel to the air, as shown in the figure below:

Pool and Miner Setup

For the installation settings of Antminer T15, please refer to the Antminer T15 Manual on the Support-Asic Miner Manual page of the ZEUS MINING's official website.

After the setting is completed, the miner enters the high-performance mode, and the real-time status is displayed on the "Miner Status" page.

High-performance mode test

Power on for 20 minutes, the overall hash rate is 23TH/s.

After running for 4 hours, the overall hash rate is 23TH/s. However, a hardware error on the hash board: 1448;

The overall power consumption is 1493.2w, and the noise of the air inlet is 83.6dB.

Energy-saving mode test

Enter the "Miner Configuration" page, select the low power consumption mode, save the settings, restart the miner, and wait for the miner to go online:

Miner status after 30 minutes of mining;

Miner status after one hour: hash rate 20TH/s, fan speed 2760rpm and 3000rpm; maximum PCB temperature: 58°C, 61°C, 65°C;

Power consumption: 1300w, noise: 83.9dB.

Antminer T15 dismantling

The connection between the control board and the hash board:

The power board is connected to the hash board:

The miner structure design is significantly different from the previous generation. Remove the air outlet cover; the internal structure is as follows:

Remove the hash board; the air duct is as shown below:

The distance between the air inlet and outlet of the T15 miner is 160mm. The distance between the air inlet and outlet of the Antminer S9 is 255mm, with more heat sinks and higher air resistance.

Note: If the miner rack of the mining farm is installed according to the earlier S9 series. Upgrading to Antminer T15, the distribution of racks needs to be adjusted.

T15 control board: front and local details

Power board: The power board is installed on the upper part of the miner. The output is routed to the power strip via copper tape. The front is as follows:

Power input and output, parameters of power supply APW8:

Hash boards: 3 hash boards in a single miner. Front and back:

Power connection: The data cable connects the power board and the hash board.

chip:

Hash board chip: BM1391AE.

Single hash board: 60PCS.

Single miner: 60*3 (hash board) = 180PCS.

Local details: some key device models: MP2019, PIC33EP16

Generalize

Mode	High-Performance Mode	Energy Saving Mode
Hash rate (average)	23TH/s	20TH/s
Energy consumption	1493.2w	1300.2w
Noise	83.6dB	83.9dB
