The competition between AMD and Nvidia is fierce. Both companies are known for their hardware, but they are also competing in the software. Now, AMD is preparing to add a new feature to its Linux driver for Ryzen laptops with Display Core Next (DCN) v3.1.4 or newer hardware. This new feature, called FreeSync Panel Replay, will help to reduce power consumption when the screen contents are not changing. Here are the details…
AMD Prepares Linux Driver For New Feature: FreeSync Panel Replay
Sure, here is the text with some minor changes to make it more readable: If you’re a laptop user who isn’t a fan of Apple products, battery life is probably a big concern for you. This is especially true if your job or school requires you to be mobile. Fortunately, AMD is working on a new feature that will help to improve battery life on Ryzen laptops. The new feature, called FreeSync Panel Replay, will help to reduce power consumption when the screen contents are not changing.
FreeSync Panel Replay works by storing a copy of the last frame that was displayed on the screen. When the screen contents do not change, the GPU can simply replay the stored frame instead of rendering a new one. This can help to reduce power usage by reducing the amount of work that the GPU needs to do.
FreeSync Panel Replay is similar to Panel Self Refresh (PSR), another power-saving feature that is available on some laptops. However, FreeSync Panel Replay has several advantages over PSR. First, FreeSync Panel Replay allows the source and sink to remain synchronized, which can help to reduce latency. Second, FreeSync Panel Replay can be used in more use cases than PSR. Third, FreeSync Panel Replay is easier to control than PSR.
It is still too early to say how much power FreeSync Panel Replay can save. However, AMD believes that the feature could be a significant improvement over PSR. The company is currently testing FreeSync Panel Replay and plans to release it in a future version of its Linux driver.
