The one thing that is different from most desktops is embedded video.
Not just "video on the motherboard", but "video using shared memory
access". This can be a problem for interrupt latency, and the CPU can't
necessarily even tell that anything bad is happening - it gets
effectively stopped while the video subsystem is using main memory
(assuming the CPU is trying to access main memory as well).
