Power consumption: difficult to separate

Based on the stress test, the power consumption table of P16G1 under different BIOS versions can be obtained:

Orange is the highest of the three, yellow is the middle, and green is the lowest.

It can be seen that the EC corresponding to different BIOS versions is the key to controlling the power allocation of CPU and GPU:

The EC 1.08 has the highest CPU power allocation, averaging 100 watts at single pressure, 72 watts at dual pressure, and 114 watts for GPUs;

The EC 1.07 has the lowest CPU power allocation, averaging only 73 watts at single pressure, 42 watts at dual pressure, and 127 watts for the GPU

The CPU power consumption of EC 1.06 is divided between the two, averaging 90 watts at single pressure and similar to 1.07 at dual pressure.

That is, EC 1.06 and 1.07, the power consumption is allocated to the priority GPU at double pressure, so that it is close to the TGP of 130W, while keeping the average power consumption of the whole machine at 200 watts, and the 230 watt power supply can easily cope with it and has better stability.

Originally, in the official spec sheet of the P16G1, the TGP marked by the RTX A5500 was only 115 watts, 1.13 fully compliant, and now 1.14 and 1.14 raise it to 130 watts.

Originally, at BIOS 1.13, the average power consumption of the P16G1 CPU under single pressure can reach 100 watts, which can already beat the 88.73 watts of the HP ZBook Fury 16 G9 tested by the author before!

Originally, at BIOS 1.13, the sum of the average CPU + GPU power consumption of P16G1 dual-pressure long-term was 72+114=186 watts, compared to the HP ZBook Fury 16 G9's 61+90=151 watts, compared to the ThinkPad P1 Gen 5 I tested before, 120 watts (or 127 watts), which is also a proper second deal!

Now, officially, for the sake of stability, overwhelm everything!

Therefore, in the above comprehensive test comparison, the P16G1 is cowardly, and even some of the results are not as good as the HP ZBook Fury 16 G9, which is the reason!

Personally, I prefer the extreme performance of the CPU of EC 1.08, and if you are worried about the excessive pressure on the power supply, you can replace the 300-watt power supply using the Lenovo Savior gaming book by yourself, which can be perfectly solved.

After replacing the 300-watt power supply, under the same test, what will be the power distribution and stability of the BIOS 1.13 P16G1 with higher power consumption and better CPU performance?

This question will be expanded on in the "Drama" section at the end of this article.

Temperature: It's hard to put into words

In the CPU single-stress test, under the three BIOS versions of P16G1, the average temperature of the CPU core and the temperature of the GPU are compared as follows (the curve color is the same as above):

Of course, the CPU and GPU temperatures are the highest under BIOS 1.13, and the lowest at 1.15.

In the GPU single-stress test, under the three BIOS versions of P16G1, the average temperature of the CPU core and the temperature of the GPU are compared as follows (the curve color is the same as above):

Of course, the temperature of the CPU and GPU under BIOS 1.13 is lower.

In the double stress test, under the three BIOS versions of P16G1, the average temperature of the CPU core and the temperature of the GPU are compared as follows (the curve color is the same as above):

Under BIOS 1.13, the average CPU core temperature is the highest, and the GPU temperature is the lowest.

The above is the working temperature of the key parts inside the P16G1 body, summarized as:

The highest peak temperature of CPU Core is 92 degrees Celsius, and the average value is between 83~88 degrees Celsius.

The peak GPU temperature is 81.2 degrees Celsius, and the average value is between 75~77 degrees Celsius,

The operating temperature of the HP ZBook Fury 16 G9 is as follows:

The highest peak temperature of CPU Core is only 91 degrees Celsius, and the average value is not higher than 75 degrees.

The peak GPU temperature is only 74.2 degrees Celsius, and the average value is not higher than 71 degrees Celsius.

In contrast, the operating temperature of the P16G1 is significantly higher by about 10 degrees, which is a very large gap.

Therefore, why is the P16G1 huge and heavy heat dissipation system so inefficient?

Or is it because its thermal grease pads are not installed in place?

Or is it because it should use liquid metal as a heat medium like the P1G5/ HP ZBook Fury 16 G9?

This, it's really hard to say...

When the ambient temperature is about 15 degrees Celsius, running the AIDA64 Stress FPU+ FurMark GPU Stress Test, the P16G1-DG-C of BIOS 1.15, the double copy lasted for two hours, and the temperature measurement on the surface of the body was immediately carried out without stopping the double copy, and the results are as follows.

Power supply: the highest point is 55.6--50.6 degrees Celsius;

Screen: the average value is about 25 degrees Celsius;

There are no exhaust vents on the left and right sides of the fuselage, which does not affect the temperature of the nearby area.

The temperature of the C surface where the P16G1 keyboard is located is as follows:

Palm rest: the left side and middle side are higher than 30 degrees Celsius, and the right side is slightly lower at about 27 degrees Celsius;

Keyboard: the left side is lower at about 31 degrees Celsius, the right side is higher at about 36 degrees Celsius, and the center part has the highest temperature, reaching 45 degrees Celsius;

Between the keyboard and the screen surface, there are two parts where the temperature is high, and the right side reaches a maximum of 49.8 degrees Celsius.

The temperature diagram at the bottom (D surface) of P16G1 is as follows:

The bottom palm rest is about 27 degrees Celsius;

The middle of the bottom is relatively high at 51 degrees Celsius---- because this part is where the GPU is located;

Below the bottom rear left and right sides of the heat dissipation ventilation grille is where the fan is, so the temperature is lower at about 30 degrees Celsius, and the highest point of the middle temperature reaches 58.5 degrees Celsius---- it should be noted that this highest temperature part is where the CPU is, due to the physical principle of infrared temperature measurement, this is already measured to the temperature inside the body, that is, the temperature on the internal heat dissipation plate.

When the P16G1 is subjected to a 2-hour double copy test, the surrounding temperature behind it is shown below:

You can see:

The heat wave discharged from the rear heat exhaust window is already placing the desktop of the body, causing two obvious high temperature bands.

There are no heat dissipation vents on the left and right sides of the fuselage, so there is no temperature rise on the left and right sides of the fuselage.

The heat dissipation vent on the rear side of the fuselage has two temperature highs, reaching 40.9 and 45.6 degrees Celsius respectively.

In summary, the author believes that the heat dissipation system of P16G1 does not perform well, and when it is double-copied for a long time, the external surface temperature, especially the temperature of the center of its keyboard, has exceeded 37 degrees Celsius, which will surely make the user's hands very unpleasant (except in winter).

Moreover, this is still when the BIOS version is 1.15, at this time the power consumption of the whole machine is only 200 watts, according to the test, when the BIOS version is 1.13, the power consumption of the whole machine is close to 230 watts, the pressure of the P16G1 cooling system will be greater, and the external surface temperature will increase accordingly.

At the same time, BIOS 1.15 when the power supply surface temperature has reached 55 degrees Celsius high, if it is BIOS 1.13, long-term power consumption is close to 230 watts, the temperature of the power supply surface will be higher, the user must be properly placed.

In the end, the author believes that the operating temperature of the P16G1 is a complete defeat compared to the HP ZBook Fury 16 G9 that I tested before!

Noise: high and low

Since the author's audio test system is not yet in place, I can only rely on human ears to listen to the record.

When the P16G1 is idle or running at medium load, the author basically has no fan noise perception.

However, after entering a long-term high-load operation state, the fan noise cannot be ignored: the sound pressure is high and there are obvious fluctuations.

Fortunately, the sound frequency is not very high, so it does not upset people.

Since no audio recording instrument is used, the author can only use the CPU fan speed in the HWiNFO64 recording data to express it.

The following figure is a comparison of the fan speed (RPM----rpm) recorded during the CPU single stress test of the three BIOS versions of the P16G1:

The average CPU fan speed of the three BIOS versions is 4807, 4018 and 4776RPM, and the peak value of 37000+ can be ignored, because HWiNFO64 is not accurate for recording instantaneous fan speed data.

The following figure shows a comparison of fan speeds recorded during a dual-stress test of the three BIOS versions of the P16G1:

The average CPU fan speed of the three BIOS versions is 4875, 4688 and 4756RPM, respectively.

As far as the author's ears perceive, the fan noise of the P16G1 when running at full speed is also inferior compared to the HP ZBook Fury 16 G9 that I tested earlier.
