The roofline model is often used to quantify the memory wall bottleneck: when arithmetic intensity (the number of operations per byte of data) is low, the system is in the "memory-bound" region.

UnverifiedThe book distinguishes model performance bottlenecks into four types: compute-bound, bandwidth-bound, memory-bound, and system-bound.70% similarUnverifiedMemory bandwidth is one of the main bottlenecks for inference latency in large models, where compute units are often waiting for data to load, a phenomenon known as the "memory wall".70% similarUnverifiedModel performance bottlenecks may stem from multiple sources, including host-side overhead, communication blocking, or compute unit idleness.70% similarUnverifiedWhen a benchmark's total score is diluted by a large number of metadata query tasks, a high score may mask a model's real weakness in geometric computation.68% similarUnverifiedA model's context window has a token limit, and anything beyond it is rejected or billed extra; in engineering, splitting, truncation, or summary compression are commonly used to control length.68% similar
