Hello everyone!
Today we are in our R&D center and going to make a review on new ASICs from Bitmain -
ASIC S15 and ASIC T15
We will check their real hashrate, consumption, noise level
and compare profitability of these two models to the profitability of ASIC S9 on immersion cooling.
So let's look closer at our new models.
They are very similar, but differ from the previous models - ASICs S9
New models have a double body
There is a dual fan, which is now located on the front side only and a built-in by two tires power supplier,
which is attached to a seat by these two tires
Distinguishing feature of these devices is that they have two operation mods high performance and energy saving
The second one will be relevant for those who have high electricity rates
Characteristics stated by the manufacturer
T15 has 23 TH/s and consumption of
1540 watts in high performance mode.
As for energy savinf mode, it has 17,5-21TH/s
and a of consuming 1050-1260W
S15 has 28 TH/s
and consumes 1600W in a high performance mode.
As for energy saving mode
It has 15,5-18 TH/s
consuming 775-900W i an energy saving mode.
ASIC T15 costs $840 and ASIC S15 costs $1249.
Prices of January 2019.
Now let's plug in the devices and check their actual characteristics
We turn the T15 on
now it is on its operating conditions and we can check such parameters as consumption and noise level.
So the consumption of the device is 1795W
Its noise level is
Is around 65 decibels
manufacturer claims 75 decibels in high performance mode
As you see the actual parameters meet the claimed ones. Let's see the web interface
Now you see the web interface of ASIC T15 which is operating in high performance mode
And here you can observe its hashrate which is around 23.2TH/s
Also, here are the boards and chips temperatures
In general there is all the ordinary information
on the miner configuration tab we can change the operation mode of the ASIC
Now we'll set a checkbox
Switch the ASIC to the energy-saving mode
And see its parameters
Here we've got a working ASIC t15 in energy-saving mode. Let's see the numbers
Consumption is over 1250 watts
Noise level
is around 66 decibels, there is no much difference since the main source of noise is a power supplier
Let's see the T15 web interface
This is the ASIC T15 web interface
The device has 21 TH/s
Frequencies are quite low and here we can see temperatures of boards and chips as usual
On the minor configuration tab we make sure that the ASIC is operating in energy-saving mode
Now we have ASIC S15 operating in energy-saving mode
and let's check its characteristics - power an noise level
Energy consumption it is 907 W
Noise level is...
Is about 62 decibels which is a little bit lower than in case of ASIC T15.
Let's its web interface
So the web interface of ASIC S15 in energy saving mode
Hashrate is about 17.8 TH/s
Frequencies data, boards and chips temperatures
Now we will switch the ASIC to the high performance mode on the mining configuration tab and check its characteristics
And here we got ASIC S15 operating in high-performance mode, let's check the parameters
Consumption is 1684W
noise level is
Is about 63 decibels
There is no much difference either
ASIC S15 web interface operating in high performance mode
Hashrate is over 28 TH/s
Information about frequencies and temperatures is here as well
Now we have all the input data to calculate the profitability of our devices
To do this we use the BiXBiT calculator on our websites
Link to the calculator you will find in the description below
Click the calculator tab
select the device type - ASIC
the default algorithm is
SHA-256
In the hashrate line we put the ASIC T15 values we got in energy saving mode
21 TH/s
Power consumption 1250 watts
Electricity rate...we put 4 cents. It's an average rate
If your rate is different
You put yours respectively
A distinguishing feature of this calculator is that it calculates two values
The pink one is profit for devices operating on immersion cooling
The gray is for devices operating on air cooling
We use the gray one as in our tests ASIC T15 was operating on air cooling
The profitability of this device is $2,05 as we can see
In the same way
using our calculator, we calculated the profitability of all other S15 and T15 mods
as well as for ASIC S9 overoclocked on immersion cooling
Link to the video where we overclock ASIC S9 on immersion cooling you can find below in the description
Using the obtained data, we have compiled the table and calculated the profitability of all our devices
Based on the data obtained it can be concluded that on the current market situation
and inflated cost of ASIC S15 and ASIC T15
ASIC S9 overclocked in immersion liquid is more profitable
Well, that's all that we wanted to tell you today
