The double-copy test in this game evaluation has always been regarded as the most direct way to reflect the performance and heat dissipation of the game, and there is a law that is recognized by the public. That is, the higher the processor power consumption when copying the machine, the better the performance is played. The better the game performance.
But the higher the power consumption of the processor, the higher the heat. For the game, the power consumption and temperature are two points that must be balanced. Then the higher the power consumption of the game processor, the better the game performance. Does the processor have a greater impact on the game?
We asked this question because we found two problems. The first problem is that the power consumption of the i7-8750H game on the market is very uneven. The high can be stably played at around 60W, and the low can be as low as 25W. The gap is very large.
The second problem is that although the i7-8750H runs differently on different models, except for the models that will overheat and drastically reduce the frequency, the number of frames in the game is not much different.
In order to find the answer, we used the HP Shadow Wizard 4 to test this game. Its hardware specifications are i7-8750H, GTX1060, 8GB DDR4, 128GB SSD+1TB HDD, 144Hz gaming screen.
The reason why this gamebook was chosen is because its processor power consumption can be stabilized at around 45W, and the power consumption is further improved after the violent mode is enabled.
At the same time, HP Shadow Elves 4 is also the only known 8-bit CPU notebook that provides CPU TDP adjustment in the BIOS (F.05 and above). It can manually control the processor power consumption limit. There are 5 gears available. 20W, 25W, 30W, 35W and default (no limit).
In the test process, the violent mode is enabled by default; in terms of games, in order to control the variables, two single masterpieces are selected: "Tomb Raider 10" and "Witcher 3"; monitoring software uses game plus, monitoring content is frame number, CPU Occupancy, CPU temperature and CPU frequency; average length of one round is about 10 minutes; room temperature is 25°.
The test method is very simple. Test the two games separately under different power consumption limits, and keep the test content consistent.
"Tomb Raider 10" test and conclusion
The Tomb Raider 10 test content is the first level, from climbing the snow mountain to being washed away by the avalanche. The test quality is preset by the system, the resolution is 1080P, and the vertical synchronization is turned off.
The following are the test results under different power consumption limits.
测试 "Tomb Raider 10" test data under 20W
测试 "Tomb Raider 10" test data at 25W
测试 "Tomb Raider 10" test data at 30W
测试 "Tomb Raider 10" test data under 35W
测试 "Tomb Raider 10" test data under default power consumption
From the test results, the following conclusions can be drawn:
1, 5 kinds of power consumption limit, the number of frames is different, but the difference is not big;
2, 25W, 30W, the default three processor frequencies are the most stable, the temperature is also high, and the number of frames is more stable;
3, 20W, 35W, the highest frame number is slightly higher than other gears, the frame number fluctuation is relatively unstable, but the impact on the game experience is small, the core temperature is low, and the frequency fluctuates up and down.
"Witcher 3" test and conclusion products
"Witcher 3" test content is DLC "Blood and Wine", from the beginning of riding to the encounter with the deserters, the whole process does not fight. The test screen is the system default height, the resolution is 1080P, turn off the vertical synchronization, close the NVIDIA hair technology, no Limit the number of frames.
The following are the test results under different power consumption limits.
测试 "Witcher 3" test data under 20W
测试 "Witcher 3" test data under 25W
测试 "Witcher 3" test data at 30W
测试 "Witcher 3" test data under 35W
测试 "Witcher 3" test data under default power consumption
From the test results, the following conclusions can be drawn:
1, 5 kinds of power consumption limit, the number of frames is different, but the difference is not big;
2. The higher the power consumption upper limit, the higher the overall frame number;
3, 25W, 30W processor frequency is relatively more stable, the number of frames is more stable, but the overall frame number is slightly lower;
4, 35W, the default processor frequency fluctuates greatly, the maximum frame number is slightly higher than other gears, the frame number fluctuation is relatively unstable, but the impact on the game experience is small;
5, the default power consumption high temperature time (70 ° or more) is short.
The results show that processor frequency is more important than power consumption
Judging from the results of the above two game tests, the following conclusions can be drawn:
1, the processor performance is sufficient, the lock power limit does not affect the number of game frames, of course, the power limit can not be too low, can not become a performance bottleneck;
2, different games have different power consumption requirements for the processor, "Tomb Raider 10" works well under lower power consumption, "Witcher 3" is better at higher power consumption;
3. The frequency fluctuation of the processor has a certain correlation with the number of frames. The frequency fluctuation is large, and the higher the number of frames is likely to occur. The frequency fluctuation is within a certain range, and the impact on the game experience is not large;
4. The more stable the processor frequency, the more stable the frame number.
Of course, the above conclusions are limited to the content and results of this test, and some of the gaps are very subtle, and may be affected by the surrounding environment, not completely correct.
However, some of the results are still worth considering. For example, the higher the processor power consumption, the higher the number of game frames, and not all games require high processor power consumption. Of course, the importance of the processor frequency is also clear. For example, the frequency is higher. Stable, the more stable the number of game frames.
Here, answer the questions that have just started. The higher the processor power consumption, the better the performance of some games, but there are games that have better performance at lower power consumption. Which game you need to watch.
The effect of the processor frequency on the number of game frames is more obvious. The more stable the frequency, the more stable the number of frames, the large fluctuations in frequency, and the high number of frames in the game, but the number of frames is relatively unstable.
The above test is carried out under fixed room temperature. Inevitably there will be errors in the test. There will be time to test more games to verify whether the conclusion is correct. Also test at different room temperature, look at the room temperature in it. roles played.
