Short-Term Optimization Ideas for ARC Graphics Cards in Low Load

[White]

Considering that the frequency of VRAM cannot currently be reduced, lowering power consumption through decreasing VRAM's frequency is not feasible. Therefore, an alternative approach could be to cut off power supply to the VRAM, effectively disabling it and significantly reducing power consumption.

Afterward, we can utilize the computer’s system memory, specifically a dedicated portion of the main RAM, as shared GPU memory. This strategy resembles the concept of integrated graphics cards but is limited by the PCIe‘s bandwidth constraints, resulting in lower bandwidth and increased latency compared to dedicated VRAM.

However, if the use of shared GPU memory alone cannot meet the computational requirements during low loads, we can also choose to disable a portion of the VRAM to further reduce power consumption.

Based on this strategy, we can define two modes for ARC graphics cards: an “Energy Saving” mode when employing the aforementioned integrated-like approach and a “High Performance” mode when utilizing the full VRAM capacity.

The mode selection can be determined by Windows’ graphics preferences, allowing Windows to automatically switch between modes based on the application’s requirements while also giving users the ability to manually choose the mode.

In summary, in the absence of the ability to reduce the VRAM's frequency, this approach shows promise for optimizing ARC graphics cards’ power consumption during low loads. I hope that together with Intel, we can address the current power consumption issue of ARC graphics cards in low-load scenarios.

Lastly, I wish Intel, as the official graphics processor supplier for the 19th Asian Games in Hangzhou, great success, showcasing their impressive performance and exceptional quality during this grand event, providing unparalleled visual experiences and gaming enjoyment for both athletes and spectators alike!
