It is also capable of addressing more memory than the SoCs used before. The BCM2711 chip continues to use the heat spreading technology started with the BCM2837B0, which provides better thermal management. Raspberry Pi designer the Raspberry Pi Foundation is working on delivering a new open-source Vulkan driver, a graphics application programming interface (API) that could mean higher-quality and faster graphics for the tiny computer.
