Games are a special breed of application since they delegate a lot of work to the GPU and often are GPU-bound, not CPU-bound. Other workloads often end up with the CPU waiting for memory accesses. The most obvious example, besides stream-processing, would be garbage-collected languages. Simply scanning the heap will benefit from all the memory bandwidth it can get. Even if speeds don't improve perceptibly because the CPU is simply waiting for the human 99% of the time it still may benefit laptop battery time due to increased power efficiency and the CPU completing that 1% sooner and returning to low power states.
