Performance modes
Lenovo Legion is no longer a start-up brand, quite the contrary. In recent years, it has gained a strong position among gaming brands such as Asus, MSI and Gigabyte. This is mainly due to gaming tournaments, where we see Legion quite often, but especially on the gaming laptop market. The new flagship Legion 7i must not only resume where its great predecessor left off, but also beat strong competition.
Performance modes
The notebook offers a choice of Performance, Balance and Silent modes in Lenovo Vantage.
All tests were done in Performance mode, but it’s worth looking at the differences between the modes. Therefore, we compare the performance course of combined load using 3DMark in the Fire Strike benchmark.
Processor clocks show a big difference between Silent and Balance with Performance. Silent has significantly higher clock, which is not a coincidence. You’ll see why in a moment.
Power draw copies the progress of clock and again we see that Balance and Performance have almost identical curves, but in this case Silent has a significantly lower power draw.
Likewise, the temperatures are higher in the case of the Silent, which corresponds to higher clock, but not lower power draw. The reason will likely be the lower fan speed. For the first time we see at least a slight difference between Balance and Performance, where the latter has slightly lower temperatures.
How’s the GPU? No load differences unlike with Blender, so it always works at full speed.
Very interesting clock graph, where we see that the modes affect the GPU more than the processor. Silent has significantly lower clock, Performance has a slight lead over Balance.
Power draw confirms the findings from clock graphs in an even better light. Silent apparently limits the GPU to 80 W, Balance is around 95 W and Performance jumps up to 110 W.
We see surprising results with GPU temperatures. Performance has the best results here, which could not be expected given the highest power draw, but the opposite is true. The reason is higher fan speeds. On the contrary, Balance tries to be quieter and therefore has the highest temperatures among the modes. Silent stays somewhere in the middle.
The differences between the modes can be seen mainly in comparison with Silent, but Balance and Performance are more or less similar. Silent loses by 14 and 18%. Balance thus lags behind Performance by only 4%, which is a relatively small difference, but definitely noticeable, especially in the GPU part.

do not buy this laptop is given, even the hinges of the screen and lenovo does not give warranty. They do not have the solution
