The new ones 4146 drivers for video cards Intel Arc they fix a problem shown since launch: excessive power consumption with multi-monitor setups. The fix, however, extends only to the use of two monitorswhile in the case of workstations with 3 or more monitors the problem persists.
Basically, the anomaly found on the new video cards of the Santa Clara house was including consumption around 40W in the presence of several connected monitors, even with the system idle. The use of different channels, and therefore a higher data flow, undoubtedly requires more power, which inevitably leads to an increase in energy consumption.
The problem with Arc video cards is that, even without a constant data stream being processed, the cards continue to draw excessive power. The new update from Intel corrects the problem, bringing down the absorption to a quarter compared to what has been done so far according to the Intel community on GitHub.
Essentially, what the new drivers do is put the card into “lower power state” as an Intel engineer suggests. However, he also points out that the feature only activates when one or at most two monitors are connected to the GPU. In the case of three or more monitors, the situation does not change compared to what has been seen so far.
However, Intel is also working on a solution for the other configurations that should arrive with subsequent updates. On the other hand, compared to the launch, performance has improved thanks to the drivers that have proved to be the biggest limitation of the new desktop video cards.
