Core decision rule: the cache determines how many cold-start reads you have to pay for, and the chip determines the cost of each cold-start read; if the configuration causes the cache to be broken every round, a chip upgrade cannot make up for the performance gap.

UnverifiedMemory capacity determines whether the parameter count plus the KV Cache can fit into the device; memory bandwidth determines the speed of weight reads during each token generation in the decoding phase, and thus directly determines inference latency.65% similarUnverifiedWhen the operating system's OOM Killer decides whether to terminate a process, it bases the decision on whether the instantaneous memory peak touches the memory limit, not on average memory usage.64% similarUnverifiedWhen running a 1B-parameter model purely on CPU, the bottleneck is mainly memory bandwidth rather than compute: every generated token requires reading the model weights from memory once, so quantization level, CPU core count and memory frequency greatly affect speed.63% similar
